Epson x900 & GMG issues
by Martin Orpen 22 Jun '12

22 Jun '12

If anybody on the list is using a GMG RIP to drive a 7900 or 9900, I'd like feedback on a quick test please: 1. Make a CMYK image in Photoshop that covers the width of whatever paper you're using and about 8-10 inches deep. 2. Fill the image with 100 cyan and 80 yellow. 3. Dump the image on the RIP and proof it on GMG Semimatte or Gloss using 8 colour mode and 720x720 resolution, bidirectional preferred, but doesn't really matter. It also doesn't matter if you've calibrated this setup or if you are running to SWOP or FOGRA39L or to a Custom Linear MX. Note that this is a test of 8 colour mode -- not the usual 10 colour mode that the x900 machines use. We cannot get this green (100c 80y) to print without both horizontal and vertical banding. The banding is gentle and looks like the green is moving from cyan to yellow -- more like moiré than mechanical issues you'd get with a head problem. In 10 colour mode our 9900 prints fine -- but that may be because the cyan and yellow ink combination is replaced with mostly pure green. I need to work out if this is a mechanical problem with a 6 month old 9900 or an issue with screening or inks? It'd also be interesting to know if anybody else notices a rather strange effect caused by the vinyl strips in the print catcher -- if you leave that green print face down on the strips for 5 or 10 minutes you'll see that the inks that were in contact with them have gone dark and need a few minutes to recover their expected colour. Never seen that happening in 10 colour or with other colour combinations... Appreciate it if anybody can help with this one and I'm more than happy to reciprocate if any other GMG/Epson users want tests run. -- Martin Orpen Idea Digital Imaging Ltd

Just wanted to thank the kind members in this forum for taking time in helping me with my project. I've come to realize that I am dealing with color professionals here and for those of you (Rudy, Edmund, Tim, Matthew, Tom; hope I didn't leave anyone out) who were generous with sharing your expertise, I am very grateful. Taking a day off from this today, so for all of you who are owed a response, one will come tomorrow. Cheers Scott Goldstein Los Angeles

Re: Help! Methinks I'm doing everything right but....

Maybe I'm posting to the wrong list..... is this a professional forum where $5K and $9K pieces of equipment are considered part of the norm? If so, please excuse my post and please direct me to a place less professional in nature. I certainly didn't mean to offend anyone. All I am asking for, as a rank amateur at this, are answers to the questions I asked so I can complete a project I am working for on my own time and dime. I'm using an Imac and Epson 3880 and trying to do a reasearch project for a non profit. This equipment is primarily used for research, printing local posters etc. It's not a graphics factory. They have no color meter so instead of purchasing a $150 or so color meter, I rented a Colormuki because I heard it was great. And given that I am doing a freebie here, A $500 piece of equipment happens to be "ultra expensive" to me. I had no idea I was dealing with a forum that traffics in high end ($9k) gear. In the words of Steve Martin, "Excussse me" for the faux pas of calling the Colormuki "ultra expensive". I wish more time was spent on helping me then deriding my choice of words. Anyway I really need help. As I said, I'm using an IMAC DESKTOP OS X 10.7 with its 27 inch (i think) screen an Epson 3880 printer Adobe Lightroom 4 I downloaded and used the latest ColorMunki software I did the screen calibration 2X. Both generating very similar results. Looks good. I then printed the color "swatches" as directed. let it dry and scanned it with the Colormunki repeated that per directions. It generated a second color "swatch" table which I scanned row by rwo and used the results to set a paper printer profile (I did this whole thing two times as well) With Epson printer control off , In soft proofing and in printing (with both the generated color profile and the Epson supplied paper profile) I get the same terrible results, high contrast, washed out prints. When I have the Epson printer control the process, the results are a lot better but still not right. I tried manually adjusting the colors, contrast, etc, but it was all hit and miss and never correct. So I really need help . I am a novice at this and don't understand things like "changing the path". This is alien territory for me I live in Los Angeles and I would be more than happy to pay someone to send time on the phone and help set this up for me. Many thanks in advance. Just trying to help out a worthy cause. PS. I can post scans if that would help. Scott Goldstein Los Angeles

Epson SpectroProofer Supported Papers
by Ken Fleisher 21 Jun '12

21 Jun '12

Hello. We just received our Epson 4900 printers with the SpectroProofer option. After installing the SpectroProofer Utilities software, it is apparent to me that Epson is basically using ColorBase for the linearization. Unfortunately, when I go to select the paper type, it does not list Epson Proofing Paper White Semimatte! I will be very surprised if I cannot use this paper. Does anyone know how I can do a linearization for this paper using the SpectroProofer Utilities software? Thanks in advance for any help you can provide. Ken Fleisher

DELL U2410 and ISO conformance
by Ken Fleisher 20 Jun '12

20 Jun '12

Hello. We use the Dell U2410 monitor for some of our less critical color stations. One particular monitor shows a pretty strong color shift from side-to-side (green-to-magenta), especially when viewing a solid gray screen. To see if the monitor has a hardware problem, I used an i1Pro and BabelColor CT&A to test for ISO 3664 conformance. I was actually surprised when the monitor passed all of the tests, since I was expecting it to fail on either the uniformity or the chromaticity. Despite the numbers, the monitor is visually non-uniform. I suspect that it is a field-of-view issue. My questions are: 1) Does it seem possible for one monitor of this model to exhibit poor field-of-view characteristics while others of the same model are significantly better? 2) Is it uncommon for a monitor to pass the ISO conformance tests yet still appear so non-uniform? 3) Does anyone have any other suggestions as to what may be the cause of the non-uniformity? Thanks in advance for your help! Ken Fleisher

Looking for the history of ColorSync
by Vincent Heuring 20 Jun '12

20 Jun '12

I've been giving a talk to local groups here in Boulder about color in general and ICC profiles in particular. I discuss what color is and isn't, and then the history of the CIE, covering the CIE color spaces, etc. Because they are mostly PC-centric groups I give them a dose of reality by talking about Steve Jobs impact, beginning with his great interest in typography and fonts, and his impact on the design of the original Mac, and the ground-breaking work by Bill Atkinson (fat bits, marching ants, etc.) I go into the early relationship between Apple and Adobe (Adobe shipping the first postscript license and the first version of Photoshop to Apple. the laserwriter and DTP). When I get to ColorSync, though I can't find any history except that Apple pioneered the CMM and the ColorSync consortium which morphed into the ICC. I'm curious about the early history: who pushed for the development of ColorSync, who was instrumental in its development, and how the ColorSync consortium became the ICC, and any other nuggets. Apple was the groundbreaker and deserves the credit. Any help/info would be appreciated. TIA, Vince Heuring

Help! Methinks I'm doing everything right but......
by Scott Goldstein 20 Jun '12

20 Jun '12

Pleas I am trying to color match my IMac computer (27inch cinema screen, using Adobe Lightroom) with my Epson 3880 printer. I rented the ultra expensive ColorMunki calibrator (since returned) and created a profile for my monitor. Did it twice. Identical results. Everything looks good and balanced. Fine Then I used the device to calibrate my printer. Printed two color patch test sheets on Epson Premium luster paper and created a profile (which, as expected, is basically the same as the supplied ICC profile for that paper from Epson) Did this twice as well. Fine But when I use the generated printer profile ( with the Epson printer control OFF), I get really funky prints... kinda stark contrasty and oddly somewhat low in saturation. In a word awful. When I have the printer control the color, it gets a lot closer to the screen image but still not right. I don't know what to do. An infinite number of thanks in advance

Color Change Going To Full Screen
by Mark Rockwood 20 Jun '12

20 Jun '12

Hello Group, Been years since I've been here. I have been shooting tethered with Aperture running on MacBooks and attached to LaCie 319 additional screens. With them set up to mirror, the image on the Lacie looks beautiful as should be expected from a calibrated screen. Problem arises when I go to a full screen view on the LaCie. The color picks up red and looks wrong. With the AD looking over my sholder the comment is the same again and again. "Wow, the color look awful". I keep switching back and showing them the image in the preview panel in the software but if doesn't stick. I have searched Apeture for a menue that will let me select the calibrated profile for the full screen view but to no avail. Anyone with experience in this area?

i1profiler and iO Table second gen with M1
by Roger Breton 17 Jun '12

17 Jun '12

I hear various reports that the path between the iO Table second gen and i1profiler isn't as smooth as can be. Right now, it seems only i1profiler supports iO Table 2nd gen, as far as supporting M0/M1/M2 modes. And that support, in effect, isn't all that successful. Does basICColor Catch supports iO Table 2nd gen in all its measuring modes? ProfileMakerPro v5 can only allow measurement in M0 with the new iO Table 2nd gen. And under Lion, forget it. Better turn to Windows. Argyll, I gather, already supports i1pro2 in M0/M1/M2. Curious to hear others' experiences. / Roger
