I am setting up a job which will be output by a a G7-certified printer, separating to a standard GRACoL2006_Coated1v2.icc profile. I have some general questions relating to some areas that might require some special treatment:
------
1) Some pages use a rich black background behind knocked out text. I have two questions related to this:
a) What is the ideal build for a neutral, rich black? My files currently have it defined as 30c,27m,0y,100k, but I can adjust as needed.
b) Should knockout text over that background have a .25pt 100k outside stroke to act as a keep-away (as they currently do), or is that better handled by in-RIP trapping?
------
2) Some images are gray (neutral or toned). Should they also be separated using the GRACoL profile, or am I better using a very high GCR separation. I have used high-GCR separations in the past for that sort of image, but perhaps the G7 process makes that an unnecessary or less desirable choice. And if I am best off with a high-GCR separation, what might be best settings for me to generate one from ProfileMaker?
------
3) My employer (not me) will be going to Hong Kong for the press check. He has often been accustomed to calling for inking adjustments as he sees initial signature output, but my understanding is that too much of this is not desirable with a gray-balanced G7 approach. Any insights?
