Re: Color server for a Kodak Approval system
by Nagy Péter 11 May '12

11 May '12

Hi Martin, depending on your customer's needs and their workflow, the easiest option would be to buy some additional modules for the existing Kodak system. As far as I know, Prinergy will do all kinds of color normalizing and conversions using its ICC or device link modules. The advantage of this solution is a very tight integration, though it comes at a price. Other packages: GMG Colorserver (the de facto tool to solve all color-related problems), Colorlogic's Zepra (very sophisticated since v2), or Alwan's CMYK Optimizer. An interesting options is Callas pdfToolbox, which is a preflight tool in the first place, but does device link color conversions, too. You might get some hot deals right now on all the items mentioned above, because of the ongoing Drupa. Hurry up! Hope this helps. Kind regards, Peter Nagy Colorcom Media Budapest, Hungary

Re: i1 Profiler (X-Rite support?)
by Jeffrey Cunningham 11 May '12

11 May '12

Are others out there getting satisfactory support from X-Rite? If so, how? If not, is this or the Luminous Landscape forum the best place to go for help? I'm having multiple issues from crashing during dual-display profiling on Vista to crashing during profiling with PM5 targets (re-measured in i1P). If I'm lucky, I get a reply from X-Rite tech support asking for more information (data files, logs, etc.), but then I never hear from them again. When I run into a problem, I just revert back to PM5, so I'm never dead in the water, but it does make it hard for me to recommend to partners. Is it just me?

i1 Profiler charts to ColorPort?
by John Lund 11 May '12

11 May '12

OK, this thread about ProfileMaker-to-i1Profiler got me thinking about how else to use i1Profiler for a specific need. Is there any way to use i1P's chart generating prowess in combination with an older, unsupported spectro? Specifically, is there a way to generate a chart with i1Profiler, then load that into ColorBurst's Spectralvision Pro (an OEM version of ColorPort), to format the chart so that SVP can read it with a DTP20 (Pulse)? Why would anyone want to do this, you might ask... well, I would like to use i1Profiler to improve the CMYK profiles used in the RIP. ColorBurst requires the use of a UV-cut spectro - hence the DTP20, since my EyeOne is UV-included. Like ColorPort, SVP can save measurements in cgats format, which i1P can import to build the profile, so I just need to get the i1P patch set formatted & read by the DTP20. I haven't had any success figuring out how to resave the .pxf file i1P generates into anything that ColorPort can use (assuming any success here should also work in SpectralVision Pro). When I go to build new target, and Import Patches, ColorPort sees the .pxf (and a resaved .txt version), but then just throws up a "There was an error importing this file" error. Maybe instead of just resaving the .pxf as a.txt file it needs some editing as well? Obviously, I have no clue. I know this is a bit obscure, but thought if there is an answer someone here will know it... Thanks in advance for any responses!

You basically import the patch data, then futz around with patch size and such until you get an identical appearing target in i1Profile that matches what you had in ProfileMaker pro. So even though you have the correct patch order and position, that isn’t something i1P can decipher. If you setup the instrument and page to match the original, then it is a matter of carefully altering the patch size sliders until you get the exact match.

...original art pigments along with the 1Ds Mark II sensor...
by Tim Vitale 11 May '12

11 May '12

I meant to say examine the color issues at the highest [screen] magnification/resolution, just before the image pixilates, in Photoshop and look at the juxtaposition of particles/canvas weave to see if they have a specific aliasing of color separation. Or, just what the hell is going on, here? I have just assumed the problem passage was sand colored. If the region is red or blue/purple it could be the PCS [profile connection space]. I'm always fighting the color changes introduced as the colors in the image go through **correction** in the profile. Most output profiles go through Lab PCS, not the more linear XYZ PCS used for monitor profiling. Bruce Lindbloom has an excellent explanation of this issue. See http://www.brucelindbloom.com/index.html?UPLab.html. Make sure you use the Munsell Display Calculator http://www.brucelindbloom.com/index.html?MunsellCalculator.html. In the Java MDC, set -- Model: Lab; Show: Radials; Select [sliders]: Hue 7.5PB, Value: 2, Chroma: 6. You will see the issue. Now move the Hue slider. The radials are not straight for certain colors, thus , blue/purple turns purple when it goes through the PCS, as does, red shift to orange. It happens often enough that I question the use of input profiles. I have certainly tried to use Lindbloom helper profile. ArgillCMS is the only tool that respects helper profiles, but it is just too basic for me, AS GOOD AS IT IS. How does the thing look if you print **without** a camera profile, just to see if it is the profile. My gut says UV and polarization are not the issue, if you have already varied the lighting positions and polarization angle. I sent you to Mike Collette because the scanning back is the *only way* to capture art correctly. The new 46 MP Foevon SD1 Merrill maybe workable as well. I have to talk with someone using the SD1 Merrill.

What do you think? Tim What is meant by very highest resolution in PS? I will do the exercise of removing the polarizing filter. Also, put the image softly out of focus. I have a UV / IR filter arriving Friday. Let's see if this make a difference. I don't follow you with this sentence: ICC profiles can't solve everything, and actually cause many problem, generally they cause fewer problems than they correct.

Subject: I suspect the original art pigments along with the 1Ds Mark
by Robert Bullivant 10 May '12

10 May '12

Need advice and help. I will start with what I am using: EOS 1Ds MK II; UV coated tubes in two White Lighting, Ultra 1800's; polarizing filters on lights and camera lens;......... Here are a few thoughts that may help; 1) I'd not reccomend using strobes to capture any artwork ever. It can adn does make ceratin pigments flouresce. This can be intensified through the use of polarizing filters. 2) The camera you are using is not ideal for capturing art work. Reccoemnd a scan back such as Phase One or Better light with a custom profile. 3) Color could be out of gamut. Robert

Need advice and help. I will start with what I am using: EOS 1Ds MK II; UV coated tubes in two White Lighting, Ultra 1800's; polarizing filters on lights and camera lens; EF Micro 100 mm L. OS 10.6.8, PS CS 5 extended. Epson Pro 9600 with matte black ink. Substrate for this client is Moab Entrada Brite. Printer, substrate, and inks custom profiled by me using i1Publish version 1.3.1. i1Pro version "D". Lens/camera/illumination custom profiled with Classic ColorChecker as well as he ColorChecker Passport. Everything converted to DNG. I only use Adobe DNG profile editor to create the custom camera profile. Also did image capture with natural light and polarizing filter on same lens. MBPro 17" with non glare display. MultiSync PA271w, custom profiles with SpectraView. My issue: ColorChecker Passport as well as ClassicColor Checker targets look fine on display and on print. So does two different white balance targets. Most of the captured image of the original art appears fine. Exception is the desert sand/dirt. I have imaged this original probably eleven (11) times. Studio flash, and natural daylight coming into the studio. Different exposures. The targets are in most of the image files, and sometimes alone. In PS CS5, camera raw, I have attempted various adjustments. First, exposure. Temperature, and other features. Then I open in PS. Immediately choose the printer profile, and continue to fruitlessly modify image. I do have a client, artist, that knows how to use selective color (much better than me). She will be in my studio next Monday. I suspect the original art pigments along with the 1Ds Mark II sensor is part of the issue. What do you think? Should another forum be more appropriate, please tell me which one. I thank you all, in advance for your advice and guidance. Cheers David B. Miller, Pharm. D. David B. Miller, Pharm.

When he would photograph different oil paintings the color would go off. We could dial in the Colorcheckers spot on but the paintings would be off. He was using a Leaf multi shot camera so it was not due to ailiasing. It was just the pigments in the oil paints. We tried polarizing on the lens and on the lights. He had to wind up tweaking each capture to correct the color. Regards, Gerry Yaeger www.TheDigitalCoach.com Now offering web based training. 619-889-6113
