Tip #8 Sample Presentation for Color Measurement

Posted by Elaine Becker on Fri, Apr 20, 2012

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.

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.

How to improve Inter-instrument Agreement with Instrument Profiling

Posted by Elaine Becker on Thu, Jul 16, 2009
So many color disputes arise these days because color instruments don't necessarily read the same.  Electronic 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 are known to read the same, then problems can arise. 

Many users assume that since they do a daily calibration on their instrument, their readings are correct.  And if they are correct, then they must match every else's.  That's not usually the case.  Spectrophotometers from different suppliers may read color differently.  Even with the same model from the same supplier, significant differences can be found depending on the age of the instrument and how well it is maintained.
