OK- I have built a profile for ColorBurst RIP (think its a good one). What do I use as an evaluation print and how do I set it up to insure I don’t mess up the evaluation print numbers (and resulting output.)
I downloaded the G7 Digital Prees Form 1- CMYK - to use as a test form. It has a section that uses CMY, K, and CMYK in to reproduce the same image- to eveluate grey balance for instance (all black, just CMY or cmy plus black.)
But I am perplexed about something- The G7 eval form is an untagged raw CMYK file- (without an icc profile.) The way ColorBurst is set-up- it always assumes an ICC profile for CMYK files if they aren’t tagged with one. In my case - ColorBurst assummes that untagged CMYK files are Gracol 2006 coated #1.
If I drop the untagged file in to the RIP - it will take the raw CMYK numbers and process them assuming they are Gracol Coated #1. Is that correct?
I tried assigning the Gracol Coated #1 to the CMYK file before sending it to ColorBurst - but that had undesirable consequences- The idnetical images made from CMY, K and CMYK that were to be used for greyscale evaluation were all converted into cmyk - all with equal values all with a overload of magenta.
I gather I am missing some fundamantal understanding here- can someone please hekp me out?
