I’m comfortable discussing it here, our process is not a secret and perhaps our conversation will assist someone in my situation!
I’ve plotted the ramps to a color list and viewed them with ColorThink, and I can see the lack of information; I’m surprised so many companies will create (and sell) a profile built from only this information!
yeah, pretty sparse isn’t it.
Our product is a 120mm circle, with a 20mm chunk taken out of the middle. (Sounds suspiciously like a CD doesn’t it?)
we’ve profiled such CD-like products in the past and, in fact, have a target set for just such purposes. it is on multiple CD’s so you need to be confident about the consistency between CD’s
I use an X-Rite instrument (528) with a 2.0mm aperture, and I’m confident that I can get at least 180 patches in the well-controlled area of our print. (The edges and extreme head/tail are poor places for measurement as a result of the limitations of our ink train)
well, that would be another way of doing it but rather painful I would think…
If you can supply an EPS (or PDF) that I can hack apart, I’ll even make the image myself if that saves you the trouble.
about our process
Our proofs were derived from a screen-printing 5-color halftone process, as you can imagine our offset (waterless on a non-absorptive substrate) process had a tough time meeting SID’s and gains!
Our engineering team has made great strides towards standardizing our output to SWOP; and now graphics is on board with a brand new proofer and color management team waiting in the wings. (To take your profile and “ruin” their beautiful proof!)
well, If you want me to send the target set over we can use it as part of our press profiling service (in reality it would not be exactly like a press profile as we would not be averaging but the press profiling pricing would apply to this special case)
I assume you have the downloaded Press Profiling kit?
