NOTE: This is a copy of a post made to another list 'printing across boarders [pab]' which I thought this group would be interested in and might be able to comment upon....
Hello and Happy Holidays Group;
I have been following several of the lively discussions in this group with great interest. I can personally attest to the fact that the efforts of the GRACoL committee have created, in addition to lively discussion, a greatly increased interesting in color verification and color process control in the Unites States. (This is a very good thing).
I do, however, have one question for committee members related to the new 126470-7 control strip. Is there a reason the reference data for the strip is not available as spectral reflectance curves?
As the developer of a client/server internet based color verification and process control system which has had paying subscribers for almost four years, and is based entirely upon spectral reflectance data we and our customers would certainly appreciate the availability of the data in such a format.
Because I know the skill level of this group I will save all the preaching about the merits of being able to transform the spectral reflectance results of measurements into alternative angle and observer pairs. Surfice it to say we work with clients across many of the printing processes, and some use alternative angle and oversrver pairs other than D50 / 2 degree. Because of this our spectrally based database hase serverd us and them well.
We are simply trying to prevent having one database structure for reference data (standards either published or self arrived at) and another stucture for the powerful and verstitle measured spectral reflectance vaules.
I look forward to any response and again with everyone a Happy Holiday Season!
