Color QC and Matching Blog
Using electronic color standards and sharing L*a*b* color values is the goal of many companies and their supply chains these days. It’s easy, fast, and convenient. If we’re all using the same numbers for our color target, isn’t that the best way to assure that we’re all matching to the same color? It is certainly more convenient than shipping samples around overnight. But before you do so, you need to understand the best practices of color measurement and for setting and maintaining numerical color standards. Many color disputes arise these days because color instruments don’t necessarily read the same. Electronic or numerical color standards are widely used and shared within a supply chain and have many benefits, but if all of your instruments are not regularly monitored and calibrated, then problems can arise.
When you buy a new PC these days, it typically doesn't come configured with a serial port. This once standard type of port has been replaced by USB ports.

The solution is to use a Serial to USB adapter cable which allows you to connect your color computer via a USB port.
When upgrading their color matching software to OnColor, many customers want to convert an existing colorant database so it can be used in OnColor.
Workers in digital imaging and publishing use color management to achieve consistency throughout a workflow. The goal is to preserve the quality and accuracy of an image from capture to final reproduction. Each device in the workflow supports a different color space. The available color management systems profile the gamut capabilities of each device, and then limit the working color space to the gamut that is shared by all of them.
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.
