We had the opportunity to spend a few minutes with Shelley as she shared some of what she's learned managing color for PPG over the years:
Color QC and Matching Blog
Tough economic times often mean having to make do with fewer resources to handle the workload. The same workload for developing new colors, adjusting production batches, and approving colors is spread over fewer people. Staff become stressed and can easily overlook color shifts they might otherwise have caught.
Well...this frequently happens when a minor colorant is overshot in the batch and the only way the computer knows to correct it is to dilute it out by adding all of the other colorants. Remember, the color computer is always trying to go for the perfect match or DE=0.00. Often times this is not the "perfect answer" in the practical world. The colorist is frequently able to accept a small color difference if he can fix the batch with the add of one colorant, or a small add of two colorants. In these cases, using the manual correction features of OnColor can solve the problem by giving you control with practical choices on how to adjust the color of a batch.
