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.

Tip #7 – Sharing the Data for Electronic Color Standards

Posted by Elaine Becker on Mon, Feb 27, 2012

While sharing the data for electronic color standards may seem like a “no brainer”, it’s easy to fall into the trap of making the assumption that the person at the receiving end of the data knows how it was obtained and how to use it.  So here are some best practices to follow to make things go smoothly.

Tip #5 – Monitor Spectrophotometer Performance

Posted by Elaine Becker on Mon, Jan 30, 2012

With today’s increasingly tight color tolerances and a global supply chain, it’s getting tougher to meet color specifications and tolerances.  How can you be assured that when you certify instrumental color data, you can do so with confidence?

Tip #4 - Inter-Instrument Agreement

Posted by Elaine Becker on Mon, Oct 31, 2011

What is Inter-Instrument Agreement? Should I care?  How do you determine it?   How do I know what my numbers are?  Can I measure it myself?

Tip #3 – The Physical Color Standard

Posted by Elaine Becker on Fri, Jul 29, 2011

 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:

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.

Using OnColor color matching software with a USB adapter - 64 bit PC

Posted by Myron Langer on Thu, Jun 30, 2011

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.
