i1P proofing profiles are great. My grand format files will sometimes have very thin transitions to rich black. The TAC is unacceptably low. In one instance when I asked for 400 TAC i1P returned a TAC of 141. With same data I performed the following: 320 TAC gives me 320. 340 TAC gives me 340. 350 TAC gives me 141. 360 TAC gives me 141. And finally, 380 TAC gives me 380. Xrite observed this behavior with my data and has submitted, in their words, 'bug' to developer. I have since received no timeline for a fix. And my favorite response to repeated inquiries was, ³use monaco if you have to² I then realized profile L* is always lighter than measured data and now want to pick my own separation by manipulating data. DLP or spot color can achieve the black I want but will not fix neutral rendering of raster data, correct? I can force a better separation by manipulating data but what will I break? :) thanks -- Dan Bergstrom | Color Technology and Quality | PRIMARY COLOR ORANGE COUNTY http://www.primarycolor.com | T 949 660 7080 C 949 616 4986 On 2/27/16, 10:30 AM, "Roger Breton" <graxx@videotron.ca> wrote:
Doesn't I1Profiler give you ample control over TAC?
/ Roger ---
Any experience out there in manipulating lab data for profiles? I¹d sometimes like to force the profiling software (i1Profiler) to pick a different TAC than it¹s default. I THINK it picks its TAC preferring minimum chroma and I want to allow I little more chroma and pick a lower L*. Or sometimes just force yellow under magenta in rich black of resulting profile.
thanks
