Color QC and Matching Blog
Much of this blog series has been focused on the instrument and getting the best possible inter-instrument agreement. However, we can’t forget the basics of good practice in color measurement when it comes to sample presentation. Some types of samples can be very repeatable to present to the instrument, while others pose more challenges.
Before generating an electronic color standard, a physical standard needs to exist and be measured to generate the electronic data. Here are some guidelines for selecting the specimen and storing and handling it:
While many of the new spectrophotometers on the market today are equipped with a USB cable to connect to the PC, most of the older models still use a serial communications cable to communicate with the PC. USB to serial adapter cables can bridge the gap for those PC's that do not have a serial port installed on their PC. There are many such devices available, but not all work well with the high demands of data transfer of a color spectrophotometer--especially not on a 64-bit PC.
When upgrading their color matching software to OnColor, many customers want to convert an existing colorant database so it can be used in OnColor.
CyberChrome Inc was an exhibitor at the recent American Coatings Show in Charlotte, NC. Featured products included OnColor Profiler for improving inter-instrument agreement and the OnColor Suite of color management software for quality control and color formulation.
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:
Paying attention to details can help you get the most out of your investment in a color matching system, get you the best color match accuracy, and get your colors approved in the fewest hits.
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.
The OnColor Suite of color QC and color matching software is licensed through use of a hardlock key. The USB hardlock key that is shipped with the software can be used on one computer at a time.
