Tip #2: Measurement Conditions and Color Parameters

Posted by Elaine Becker on Tue, Jul 12, 2011

The next fundamental rule in sharing electronic color standards  is that the color parameters using in the calculation of the coloriemtric data must be the same.

10 Tips for Using Electronic Color Standards

Posted by Elaine Becker on Thu, Apr 28, 2011

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.

Color Management: The Pathway to Consistency

Posted by Elaine Becker on Wed, Jun 16, 2010
  This blog post was authored by John W. Root of Mt. Baker Research.

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.

Color Geometry: A Matter of Degrees

Posted by Elaine Becker on Tue, Jan 05, 2010

Long before computers were invented a radio, film, and television comedy team known as Abbott and Costello perfected a classic skit that became known as the "Who's on First?" routine; essentially a dizzying five-minute display detailing by example the pitfalls of miscommunication via homophones, homonyms, home-run hitters, and high comedic art.
