Using Optical Brightener Compensation (OBC) for Profiling Printing
Conditions on a Press
The OBC Module is mainly targeted for inkjet and xerographic printer workflows, as the generation
and print of the Gray Evaluation Chart does not easily translate into a press workflow. Users who
wish to use the OBC Module to profile their press should check if the paper used for production
on the press could also be used with an inkjet or xerographic printer. The user would then print the
test chart both on the press and on the inkjet or xerographic printer. Step one would be to print and
measure both the CMKY/RGB test chart and the Gray Evaluation Chart from the inkjet or xerographic
printer and assess the results under appropriate viewing conditions. Step two would be to repeat this
process from charts printed on the press. In a final step the user would match the results of step 1
against those of step 2, but use the results from the Gray Evaluation Chart printed on the inkjet
or xerographic printer to enter the information on the amount of UV preset under the viewing
condition into the OBC Module.
ProfileMaker Certification of Proofs based on OBC Profiles
To control the quality and validity of a hardcopy proof according to ISO 12647-7*, hardcopy proofs
must contain a control strip (e.g. ugra/Fogra Media Wedge or IDEAlliance ISO 12647-7 2007 Color
Control Strip.
*ISO 12647-7: Graphic Technology – Process control for the production of half-tone color separa-
tions, proof and production prints – Part 7: Proofing processes working directly from digital data
