How close can a proofer, in terms of Delta-E values, should I be able to get to my real print? The proofer is a Fuji Final Proof. Our printing process conforms to TR001 (SWOP) specifications.
Here’s the deal:
Our proofer vendor has used Gretag Macbeth Profile Maker to create a Device Linking Profile.
The proofer data was from a file we output and he presumably scanned or auto-read. (IT-8)
The print data was from a color list created by hand; Lab* data for 875 patches.
Also provided was the CMYK blend of each of those 875 patches.
What was returned to me was; a proofer profile, a printer profile, and a device link profile.
Proofs created using that device linking profile measure slightly closer to the print, but not nearly dead-on. (Closer than the previous set of curves in the proofer, which were created by hand years ago) I would estimate that around 2% of the vectors are under 6 DE, 48% are between 6 and 10 DE, the other 50% over 10 DE.
I expect much better results than this… am I being unreasonable?
I can attach profiles and color lists and whatnot if that will help.
