I want to try and get some other suggestions on color settings for the igen using the freeflow rip.Right now all files we send to the igen are converted to Rgb. I am not real happy with the way the black lays down even though you get the very blackest black you can get with RGB it does hurt my images.What i am looking to try some testing on is maybe sending all file CMYK instead of RGB.I would like to have some settings from people who are matching color very well and we are also trying to match the Gracol standards. What i would like to have from some folks is the settings that you use in your advanced settings. Rgb color space,CYMK color space, Destination profile (custom?), Rendering on your data. We do bulid our own TRC to adjust our color specifics but i am tryng to better our overall laying down of color. Im reaching out to you guys to get some other some suggestions to try to improve my overall printing and smoothness of color.Not that mine is unacceptable now but i want to improve more and get the very best i can.The settings that i use right now with our own TRC is as follows-- RGB color space-AdobeRGB CMYK color space is GRACOL 2006 Coated v2 CMYK-Gray color space is Gamma1.8-text graphicsIgen gray-Destination Profile is Xerox igen3 Max GCR-Rendering Data is alll data Perceptual.

What I find with questions like this is people don't like to share their "secret recipies ". You may not get many responses because of that, but I feel that we are all in the same boat and we all can use information to make us ALL sucessfull. Thats what makes Forums so great..

Anyway..

I use similar settings as you although I do not use the same. I have 3 Queues I use for all my jobs and tweak as needed. 1) For the brightest colors I use Igen color for rendering the brightest colors (tends to make fleshtones yellow though) 2) Gracol but with RELATIVE not perceptial and SRGB. Relative and srgb seem to be better for photos and adobe and perceptual for graphics if I remember correctly. 3) I create a Swop Queue for the in between jobs tends to warm thing up. I rarely use Adobe color and almost never use perceptual.. I also find that with the latest software using "edit image" set to Hi Saturation you get more depth in the color and use this as a default in all my Queues.

That said I have a question..

I have a problem with Black only text (and sometimes graphics) printing as 4c screened instead of 100% Black only. I have been fighting this off and on for over a year now with Xerox. Has anyone seen this besides me. It started happening 2 versions of software back on my Doc USP and continues to this day. I have some work arounds that work 70% of the time but still cannot fix. Funny thing is when I had the last software upgrade the problem we gone and I could not reproduce but after about a month it came back and is still a problem. Anyone else seen this or know how to remedy. I have had Xerox working on the problem for some time know..

Thanks!

Yes I agree Dale I may not get to many secrets from others but i would hope that others would be will to help as i know i would help other users if i could. All of us has the same goal and that is to produce the very best we can for the company we work for. So hopefully i will hear from others and if i can help anybody with something i will.I run a an igen that has 3 feeders with a bourg bprf and a bourg booklet maker with a challange 3 knife trimmer on the end all inline so alot of my work is perfect bound books but i also do alot of full color sheet work too.When making books i run 4 to 5 different papers at the same time.So if i can help someone in that area let me know.

Alot of the color issues aren't from the Igen but actually the file and how it was designed. You can get a screened black if the file was designed with a build black. Depending on the program used, Word is the worst at color, the program uses a percentage of cmyk to create the black. Adobe In-design is the best program for helping with color. If the file was made in another program you can make a pdf of it and drop it in to and In-design layout. There is a tool for looking at the color separations. This will show you how the Igen will print the file. If the black is "built" and not a solid Black/K. I also have found that having a file designed with Pantone colors will alow me to use the Spot Color tools on the Igen DFE this allows me to change the CMYK percentages to match what the customer wants. I can then reset Pantone Spot colors to the default numbers. I do use TRC's but very rarley I can not get accurate and reproducabe color. To maintain the Igen color I make a Desination Pofile for my Igen every 6 mos. and of course mantain color calibration.
