ABW ICC profiles for Epson 3800 and Macintosh

Filed under: Printing — admin @ 2:20 pm

Free ABW (Advanced Black and White) Profiles for the Epson 3800 and Macintosh

NOTE: 12/25/09 – As of 10.6.2, these profiles will not show up in Photoshop. Apple made some kind of change that wreaked havoc on ICC profiles in OS 10.6.2. I’ll try to get these fixed, or perhaps 10.6.3 will fix them. (My fixes, when available, will not be as complete, since I don’t use some of those listed papers any more.) See my more recent blog post “Suddenly, gray borders on photo prints” for more details.

I’ve posted here my Epson Advanced Black and White (ABW) profiles for the Epson 3800 printer with K3 inks, and the Macintosh computer. (Note: profiles are posted as I create them.)

Included in the single zipped archive are ABW profiles for 17 papers:

Canson Arches Museum Velin Rag
Canson PhotoGloss Premium
Canson PhotoSatin Premium
Canson Rag Photographique
Epson Enhanced Matte
Epson Premium Luster
Epson SemiMatte
Epson Velvet Fine Art
Epson WaterColor
HawkMountain Sharpwing Luster
Hahnemuhle Bamboo
Hahnemuhle Fine Art Baryta
Legion Entrada Natural
Mitsubishi Gekko Blue
Mitsubishi Gekko Green
Museo Max
Red River Ultra Pro Gloss

Click here to get the profiles.

NEW PROFILES – to get around the 10.6.2 ICC profiles issues are below. They include:

Epson Enhanced Matte
Epson SemiMatte
Epson Velvet Fine Art
HawkMountain Sharpwing Luster
Hahnemuhle Fine Art Baryta
Legion Entrada Natural
Mitsubishi Gekko Blue
Mitsubishi Gekko Green
Museo Max
(write if you want one of the others)

Click here to get these revised profiles.

NOTICE! These profiles were made for MY setup, and are therefore provided AS IS. In exchange for getting them for free, you acknowledge that they may be completely unsuitable for you, and you are using them at your own risk.

The profiles were made using “No color management / printer manages color” setting with perceptual RI, and ABW set to “Normal” and all other settings to zero. Prints were allowed to try for 24 hours prior to measurement.

The paper manufacturer’s recommended paper setting was used in all cases.

The way the names will appear in the profile list in Photoshop is this:

Each will begin with ABW_ (making it easy to keep them all together.)

Next is the manufacturer’s code:
CA = Canson/Arches
HK = HawkMountain
HN = Hahnemuhle
MU = Museo
LP = Legion Paper (Moab)
MB = Mitsubishi (Gekko)
EP = Epson
RR = RedRiver

next is the paper

If a number follows, it is the weight of the paper

and finally the paper setting used
EM – enhanced matter;
VFA – velvet fine art;
WC – watercolor;
PL – Premium Luster;
PG – Premium Glossy;
PSG – Premium SemiGloss

To use these profiles, do this:

Place the profile in your ~/library/colorsync/profiles folder.

When printing, choose “Photoshop manages colors” and select the appropriate ABW profile. Set the rendering intent to perceptual.

In the print driver dialog, be sure you have selected the proper paper, and set it up for ABW printing, using the same settings as I did when creating the profile.

Remember that matte paper really needs 12-24 hours to dry, and will look darker when first removed from the printer. If after 24 hours, what you’re seeing is too dark or too light compared to your (properly calibrated) monitor, then repeat the print, choosing darker or lighter from the ABW popup, instead of “Normal.”

Thanks to Roy Harrington, maker of QuadTone RIP , for his permission to use his script to convert my raw numbers into actual ICC profiles and distribute them.

On my paper choices: matte for B&W

Filed under: Printing — admin @ 7:05 pm

I print using an Epson 3800 with K3 inks.

I’ve just spent a couple of months and many hundreds of dollars running my own tests on papers from a number of manufacturers, from Red River to Canson. I’ve run standard tests, and then from those chosen papers for my own hand-made ICC profiles.

Now, paper is a highly subjective choice. Not only does it depend on the artist’s eye, but within his range of photos, a type and warmth (or lack thereof) depending on the image and artist’s intent.

I generally think of mattes for B&W since I love the deep blacks and velvet tones that a matte paper affords. But then that does not apply to all B&W photos, as some demand brilliant white highlights. You may or may not want to peer into the shadows; you may or many not want a silver tone. And the save type of caveats apply to surface textures.

So my own predilections are – for B&W: mattes with a very flat surface, and for color, a RC paper… generally speaking. That’s my “bent” not hard and fast rules.

And that said, in terms of matte papers, I have got to say that for my tastes those from Canson/Arches were, across the whole line, quite fine. After testing hundreds of sheets of paper from all the more common names, I tested the Canson products last… because as others have noted, they are probably the most expensive papers, and testing is not cheap. That said, I guess it should have come as no surprise that the paper chosen by Picasso, Miro, Renoir and others turned up at the top of my tests.

Deep rich blacks and a wonderful ability to accept the full range of tones made them stand out. My carefully crafted nuances translated perfectly to the paper. The feel of the papers was of quality, and if they were a buck to two more per sheet than all of the others, it was money well spent.

Mechanically: no dust; no cruft. Perfectly flat out of the box. I had found my matte paper.

(Caution: you cannot roll these papers for mailing; they must be sent flat.)

Particularly, I liked the Arches Velin Museum Rag. If I had to choose just one Canson paper, this would be it. (For proofing this paper, try Red River Aurora Natural 64lb.) The Canson BFK Rives is also a delight. I’d honestly have to mention all their matte papers to be fair, since all of them were simply excellent (although some had more texture than I care for.) I have never “gushed” about an entire line of paper before, but this is the exception that proves the rule.

OK… let’s be fair: are their other good matte papers? Sure, and nice ones too.

For papers with OBs, the Epson WaterColor and Velvet Fine Art and Moab Entrada Rag Bright are good, as is the Red River Premium Matte 2.0 or Plus. Without OB’s it’s Canson first, followed by Museo Max; Entrada Natural and Hahnemuhle Photo rag or HawkMountain Condor Natural.

I’d like to suggest that you get a sampler of the Canson papers and have a go at it. I think you’ll be as pleased as I was.

Next up: the RC (resin coated) papers for B&W.

Framing the Fine Art Photographic Print

Filed under: Techniques — admin @ 12:44 pm

Framing a Fine Art Photographic Print

Framing a photograph can be done several ways. The most common is without a matte, and is usually a photo of friends or loved one. Fine photographs, on the other hand, are virtually always matted. Beside the fact that this separates the surface of the photo from the rear surface of the glass (thus protecting it from sticking and other damage) the matte sets off the photo, and provides isolation from the surroundings; a “viewing area” if you will.

Framing is itself an artistic endeavor and thus subject to individual tastes. Therefore, I’m describing my own sensibilities here, and not hard and fast rules.

Paintings are often enhanced by the choice of a fancy frame. We have all seen those cases where one wonders whether or not the frame itself was not the object, rather than the painting it housed.

Photographs, on the other hand are diminished by ornate frames. A photograph is a captured instant, a single moment extracted from the flowing river of time. The viewer moves into a photograph as though he were there at that moment, with one big difference. Since that moment is frozen, he do something he cannot in real life – observe and blend every instance and detail into the whole it truly is.

Further, a photograph is composed by the artist. It is a chosen point of view, a perspective. And just as one uses “point of view” and “perspective” in an intellectual or argumentative sense, it is used in the physical and spatial sense with a photograph. That is: the artist is positioning you in space and time, and presenting you with an intellectual statement.

With all of this going on – with the striking depth of involvement which one can experience with a fine art photograph, the context in which it is placed becomes paramount.

That context is the presentation: the frame.

I always choose a simple thin black frame. This serves the purpose to draw a pronounced but unobtrusive rectangle around the image, separating that area from its surrounding. This deliberate choice says “look here.” In keeping it plain, thin, black and simple, it serves this purpose only, and does not call attention to itself – only to the object it contains. In short, there is no need to look at the frame, as there is nothing of interest to see on it.

As for the matte – considerations include color and width, as well as matting style.

There are single and double layer matte and I prefer the former, for the same reasons I prefer a simple frame: to my senses, a double matte merely makes the viewer think “look at the fancy matting.”

The color of the matte should enhance the photograph, or at the very least not detract from, nor alter it. The tone and color of a fine art photograph has been painstakingly worked by the artist, and the color of the matte, if it is anything besides a neutral tone, will alter that for the viewer. This applies whether the photograph is color or black and white.

In some cases, a bright white matte is appropriate, while in others, an off-white or even creme-tone is a better choice. In short, you must match the matte to the print itself.

Now, I’m making an assumption here, as expressed in the title of this piece: that you’re truly working with a fine art print: one which has meaning for you. If you are instead working with a designer and color-coordinating a room, and the matte “simply has to be lime green” then I’d suggest you choose a photo based on its colors, not it’s “message.” The choice may still be a fine art print if you’re very fortunate, but will likely be a more conventional “pretty” photograph.

The width of the matte’s borders needs to match the size of the image within, and the size of the frame; it’s a bit of a balancing act. A larger frame (say 18 x 24 and above) with a matte width of 1″ on a side will look out of proportion to the print, and fails to provide enough isolation to separate the image from its surroundings.

Equally, a 4″ x 4″ photo in a 20″ x 20″ frame has 8″ margins around the image, reducing the photo to 1/25th of the area, and results in a pretentious and unbalanced presentation.

It is that sense of a comfortable separation, a “viewing table” if you will, which determines the appropriate matte border width.

Finally, there is another consideration: is it the image or the print that you are displaying? For example, the images of Ansel Adams made him famous, but owning one of his original prints is a prize as well. The print is valuable because of the image it holds, but an authentic Adams print also has an intrinsic value.

Because the fine art print is carefully cropped by the artist, any matte which covers it, even slightly, defeats the artist. A photograph is largely composition and balance, and the photographer has very carefully chosen what is included and excluded; chosen the ratio of length to side; and skillfully ranged the tones from center to edge.

Your choice is to have your matte come directly up to, and slightly over the edges of the image, or you can back off a bit, and show some of the paper on which the image rests.

framing.jpg

I find matting which covers the image even a tiny bit to be a choice which fails the intent of the artist. In short, I favor the style of matting which allows the full image to be displayed, with a bit of the paper showing, for the reasons stated above.

Yet as with all artistic “rules” this too can be broken. For example, some photographs are taken with the full intent to be matted, and allowances therefore made by the photographer. Portraits spring to mind as an example of this category.

So there we are: several things to consider when framing and matting a fine art print: frame, matte, color, size, and edges, with most of it dictated by the print itself. If this all seems a bit intimidating, you can simply take the print to a framing shop, and work with the framer there, who will no doubt be well aware of all this, and can guide you through the process.

Should you choose a framed print from my collection, you’ll likely find it conforms to my preferences as stated above.

Digital? Shoot at 5.6

Filed under: Techniques — admin @ 12:42 pm

Here’s something most folks don’t know about digital cameras: in terms of a quality, well-resolved photograph, you should stay away from the smaller apertures. F22 is too small.

If you’re fortunate enough to have a full-frame sensor camera (such as the Nikon D3/D700 or Canon EOS 5D, for example) you can go to about F11. With better DX (half frame sensor size) cameras, such as the Nikon D300) you can go to between 5.6 and 8; and with little consumer cameras, you should stay at f4 or 5.6.

What’s up with that recommendation? Well, it get a bit technical (see “Airy disc” online for details) but it basically comes down to the smaller the aperture, the bigger the point of light on the surface of the sensor. And if the point of light covers several “pixels” (individual sensors) you’ve lost resolving power.

Even before that happens though, you’ll start overlapping the sensors, and will end up losing contrast, which appears to the eye as a loss of resolution.

Ever wonder why your digital photos look “flat?” That’s why.

Yes – it’s a trade off between resolution and depth of field, and it’s an agonizing one. If you -need- the depth of field, and have to go above f11, you’ll lose some resolution.

A solution might be to go with a lens with a wider angle. Equally, setting your zoom to the wider end of the scale will open up the aperture on many lenses.

If you’re a photographer, you owe it to yourself to run a few tests to confirm how this affects your particular setup.

Meanwhile, (and this is a generalization, varying by sensor size/density, but the gist is correct:) just remember that you’ll get sharper photos at around f5.6 than you will at f22 with your digital camera; that your sweet-spots are between f4 and f8.

George DeWolfe: sorta…

Filed under: Corrections — admin @ 9:42 am

Have “experienced” George DeWolfe’s “Digital Photography Fine Print Workshop” book.

Didn’t say read, because Mr. DeWolfe is a talented photographer but annoyingly and extremely full of himself.

It’s this latter part that made the book so hard to read. He spends a huge amount of time telling the reader how great he is, and how fortunate they are that he is sharing his wisdom.

Very tiresome.

And, of course, there are the parts where he’s wrong.

Such as in his basic workflow, where he places noise reduction as the last thing done to the photo, prior to sharpening and printing, because “Noise…is the exact opposite of sharpening.” Huh? “Blur” is the exact opposite of sharpening.

This is a computer, folks, not a sentient being. Computers run programs that are looking, in this case, for a very specific condition: CCD noise and color noise, so it can effectively remove them.

It is NOT looking for contrast enhanced, color corrected, noise. It will never find that… because that’s not what it’s looking for.

You want your noise removal done as _early_ in the workflow as possible, not as late as possible.

As to the book as a whole, I’d give these comments:

It’s a very basic beginner’s book. If you want Fine Art Print information, get “Fine Art Printing for Photographers” by Steinmueller and Gulbins.

DeWolfe’s artistic advice is much better than his technical advice. If you want a good book on photos in Photoshop, get Martin Evening’s “Adobe Photoshop CS3 for PHotographers.”

Epson 3800 prints too dark: FIXED!…

Filed under: Tales from the trenches — admin @ 10:07 pm

… at least for me. As soon as I went from PS CS2 to CS3, my prints came out 1.5 or 2 stops too dark. Drove me nutz.

Search on the web, and I see I’m hardly alone. Call Epson, and they admit it… but have been working on a fix for nearly a year now. Sigh.

Then tonight, I’m determined to find it, and I start mucking about. One of the things I did was turn on print preview, with my chosen paper profile. And on a whim, I clicked on “Preserve RGB numbers” and saw exactly what the printouts look like: way too dark. A clue!

Off to Adobe help, where I find that the definition of “Preserve RGB numbers” is ” Simulates how the colors will appear without being converted to the color space of the output device. ”

Hmmm… is it possible that the output is not be converted to the printer’s color space for some reason?

If so why, and what can be done about it to fix it?

Off to look at my profiles… to discover that I have two full sets of Epson 3800 profiles… one at /Library/ColorSync/Profiles and another at /Library/Printers/EPSON/InkjetPrinter/ICCProfiles/Pro38.profiles.

Hmmm… do I have a conflict here? Should not be, but on a whim, I delete the batch of profiles at /Library/ColorSync/Profiles, and head back over to PS to see how thing work now.

And the result is… “things work now!”

No more excessively dark prints.

Is this the reason that it was so hard to find? Double profiles? Some had them and some didn’t? (The ones at /Library/Printers/EPSON/InkjetPrinter/ICCProfiles/Pro38.profiles are, in fact, inside that package, so not very obvious.)

Did I find it, or were the gods just smiling on me? Taking pity?

See if that is your circumstance; see if that fixes it for you.

Good luck!

Setting White Balance with a Gray Card

Filed under: Techniques — admin @ 10:31 am

This is for the more serious photographers and videographers on the list, and there’s no doubt that some of you (certainly the pros) already know this… but some may not.

White Balance.

The human eye is very adaptive: take a sheet of typing paper outdoors, and it looks white. Take it indoors and it looks white. But that’s just our brains at work. Photograph it out doors and it looks slightly blue; shoot it indoors and it looks significantly orange. That’s because it’s not the paper – it’s the light.

In the film days, this was compensated for by using indoor or outdoor film, but in the digital age, it’s done in your camera. Every digital camera offers “automatic white balance” and often a range of cute little icons for outdoors (sunny) outdoors (cloudy) indoors (incandescent bulbs) indoors (florescents) and so on.

And better cameras will also have “custom white balance” as well.

Now: if you go to the trouble to set your white balance for a given lighting situation, there _will_ be a visible improvement in the color accuracy of your print.

The process involves choosing “custom white balance” in your camera’s menu, and then shooting something “white” filling the frame. That setting is then saved, and used as long as you don’t change the lighting in the current environment. (If you do change it; go outdoors; whatever, you have to go thru the process again.)

Except that my description above is incorrect. The bit about “shooting something white” is where it fails… because (unless you’ve paid for it specifically) “white” isn’t white. White typing paper, for example, has optical brighteners in it which reflect more blue, making it appear whiter to the human eye.

“White” as far as the digital camera (or digital video camera) is concerned is (here’s the key) -equal- amounts of 100% red, 100% green and 100% blue. On a scale of 0-255, for example, that would be R255, G255, B255. White light is an equal mixture of all the primary colors.

Your white typing paper is probably something more like R240, G248, B255. And those are not fixed numbers for typing paper… what I’m saying is that your white typing paper is really R?, G?, B?.

What you’re tying to achieve in white balancing your camera is, not surprisingly, “balance.” You want to photograph something under the “custom white balance” setting in your camera that is EQUAL amounts of R, G, and B.

And fortunately, that’s easy and inexpensive: take a trip to your local photo store, and buy an “18% gray card”… because gray IS, by definition, equal amounts of red, green and blue.

Take your white balance setting off of gray card, and you’ll see your color accuracy jump _way_ up.

“Balance” achieved.

Finally, as many of you know, if you also include the gray card in one of the photos in a given lighting situation, you can use that later on in Photoshop to help adjust the photo colors was well.

HDR sucks… most of the time

Filed under: Uncategorized — admin @ 2:01 pm

HDR Sucks.

OK: most HDR is poorly done, and that’s what sucks; even with CS3, there is no free lunch.

“HDR! Better than sliced bread! Faster than a speeding bullet!…”

As I write this, it’s the winter of 2008, and you cannot pick up a photo magazine, computer magazine, or visit a website without someone screaming at you about HDR photos.

“High Dynamic Range” or, as I call it Too Much of a Good Thing.

Remember this? Back when the Macintosh first came out, and WYSIWYG and Postscript came along, it was at long last possible to create straight lines, and use various types without having to be a graphic artist.

Proof that PostScript did not a graphic designer make, was amply supplied by thousands of barely readable newsletters sporting 46 different fonts on each page.

It was horrible. Look – just because you bought a hammer, doesn’t mean you’re a carpenter, but it does make every problem look as though it can be solved with a nail.

Well, here we go again.

Photographers have historically been plagued with low dynamic range (the amount of detail from the blacks to the whites, usually expressed in EVs or f-stops.)

Early tintypes and early film had a limited range 5-7 stops. Film runs from 8 to 19 or so stops. A digital camera runs from about 9 to 12 stops.

The human eye is about 7 stops. That is, when you’re looking at something in particular, your iris settles on a size, exactly like the aperture of a camera, and at that given size, you have the ability to see a light intensity of about 150: 1 (or just slightly greater than 2^7 – [7 stops].)

Since early photography was also about 7 stops, it was well received… but ultimately a little frustrating. Looking at the photo as a whole, the image was perfectly satisfactory, but because a photograph is a fixed moment, we always take the implicit invitation, and look into it, trying to pick out interesting details. And with a limited EV range, the detail was lost, either in the shadows or the highlights.

Thus photography became at least in part, a quest for additional range. But that quest can be carried only so far, before it starts going “over the edge,” and then no longer looks “right.”

It’s that threshold we seem determined, like a child with a new toy (or a wanna-be graphic designer with Postscript fonts) to exceed.

Look up from reading this right now. Glance around. Look at bright areas and dark areas. Really look – how much can you _actually_ see in the darkest shadows? What happens when you look at something bright? Can you see it, while at the same time, see into the shadows?

No, of course not. The iris opens and closes. In fact, you cannot -clearly- see anything except the tinniest field just around your direct line of sight, and focus. (Your mind may fill in assumed details, but as I said: really look, paying attention to what you can, and cannot, see.)

My point is that what you see is 7 EV… and if you stare into the shadows, you’ll open them up a bit… but not more than 7 EV. Ditto for bright areas. And at no time will you ever see more than 7 EV. It’s a sliding, but fixed, range. We don’t see much detail in dark areas (our eyes “have to adjust”) and humans are very bad at seeing in the dark. We do much better with more light… but it can get to be too bright for us as well, although it’s not as several an impediment as the low light level issue is.

So I’d suggest that about 12 will give us enough leeway to look into the shadows, and recoup some of the blown out whites. (The famous Zone system had 11 tonal areas.)

Fortunately, I own a camera that will provide me with about 12 EV, but what many do, and what I’m discussing here, is the 3-shot, 2 stops over; 2 stops under; one right on; blend-them-together technique so avidly discussed these days.

But, and here’s the problem: it’s not “evenly spaced.” That is, when you overexpose by 2 stops, you’re making the shadows 2 EV brighter. And in the 2 stop underexposure, you’re cutting down the highlights by 2 stops.

In short, you’ve giving the viewer a 4x extension of the light in the darkest areas where we do not see well, which is completely abnormal, since humans don’t see into shadows well, and then, with the underexposure, you’ve _cut_ (not extended) the range on the high end.

In short, you have a picture with a 9 EV range, pushed toward the shadows.

I’ve seen on the cover and in feature articles of well respected journals, read by many a professional, photos with such “high dynamic range” and they look terrible!

The problem is what happens to the middle range: the main perceptual area of the photo as a whole: it becomes “thin.”

In fact, I actually mistook the cover of a recent “Photo Techniques” for a pencil and watercolor drawing on first glance… as did my wife, who is a painter. It was a photo taken inside an old, trashed and abandoned room, with windows opening to a sunny day outside.

Yes: I could see into all the shadow areas, and make out details out in the bright sunlight. However (and here’s the point) I have never had such an experience in my real life, using my real eyes… nor has my wife, which is why, on first look, we took the photo to instead be an illustration: it simply had no relationship with reality.

In fact, it reminded me of what happens in poorly done audio these days: it’s compressed (I’m talking frequencies, not file size here) beyond all belief so that it can be played loud. Musical nuance is gone; harmonics are gone. It’s a large, flat monotone without any human expression…

… and it fails as music.

Most HDR is similarly overdone: “brightness” is just tacked on to the image in a haphazard way, “opening up the shadows.”

It fails as a photo, as it’s no longer within the range of human experience.

Fortunately, just as we are no longer stuck with 46 fonts per page, and the wanna-be graphic designers eventually returned to their day jobs, leaving the trained designers to produce nice works with no more than 2 fonts per page, there _is_ good HDR.

It’s not simple to do correctly, but at least there is a correct way to do it.

First, make sure that you’re not shooting automatic anything! Particularly, be sure automatic white balance is off. Turn off auto-focus. Use a tripod. Shoot -2, 0 and +2 EV.

The, for your print, you open up the shadows, but not necessarily all two full stops. You put the extended range in the _middle_ of the picture, not at either end. Leave a bit of blow out if it’s called for. Leave some pure black.

You want darkest pure blacks; blacks with only a hint of shape; blacks with some tone; blacks with some texture. If you open it up so much that none of your blacks fall in the first three categories of that list, you’ve overdone it.

Extend the detail in areas of the photo, not all over it. THINK about what you are doing. If you are sharpening to draw the eye, then provide the extra range there, where the eye is drawn. That’s what masks are for!

Open the shadows a bit, but only in the deepest areas; do not let it spill over into the middle tones. Opening the shadows should be done very modestly if there is a 150:1 tone range (ie daylight) but can be done more strongly when the tone range is 20:1 (a darker subject) because that is the way our eyes work.

Do not increase the shadow detail in the middle range (or at least not much) – keep it at 8 or 9 EV… for exactly the same reason. (Ansel Adams considered the bulk of the image to be within the center 9 zones.)

In fact, go look at some good black and white photos, and notice the tone range. After all, EV is a measure of luminosity, not color. Study the prints of Weston, Adams and the other great B&W photographers. There you will find a rich, velvet and lucious range of tones, all of which invite investigation.

Personally, the first thing I do when working raw is turn off the color and look only at the luminosity, in LAB, and get that set right. Then I pop the color back in.

Having HDR can be a good thing, yeilding spectacular and moving prints… or it can be like a newsletter with 46 fonts per page.

If photography were a entirely mechanical craft, then Photoshop could do all the work for us, but it’s not: it’s an art, which takes human experience, skill and judgement to do correctly.

You want a great photo? Plan on spending some quality time with it.

Why are my photos colored magenta (& other mysteries)?

Filed under: Techniques — admin @ 2:53 pm

Here’s an introduction to how to do color matching; what it is; how to set it up; and why it works. If you’re new to digital photo printing, or just confused as to why your prints don’t look like what you saw on screen, this simple “no geek speak” intro is for you. I wrote it years ago, but it’s just as valid today as it was 4 years go.

It’s so long however, that I’ve put it on a separate web page, which you can find here. (www.tracyvalleau.com/colorprofiles.html, just in case the link gets broken…)

Longer banners on the 2200 and changing ink…

Filed under: Techniques — admin @ 7:38 pm

Epson 2200 banners longer than 44 inches can be made by using GIMP print.
(Originally posted 2/5/05.)

In fact, longer than the roll paper you can buy (which is 32 feet.)

Here’s a couple of things to be aware of:
1) there are no profiles for GIMP. (I’ve made my own using PrintFIX, but the license won’t let me share them. Sorry.)
2) The default GIMP settings over-saturate the image.
3) The rotation direction is 180 degrees opposite from that used by the Epson drivers: instead of left-edge first, it’s the right edge.

And one last tip: if you run out of ink (OK: before you run out of ink, and when you see the blinking lites indicating low, and you decide you don’t want to risk it) do NOT use the software to pause the printer for reloading!! (You’ll have to start over again.)

Simply hit the ink button on the front of the printer, and replace the cartridge. It will continue printing seamlessly.
