Color viewing and tolerance standards have been established to ensure colors can be evaluated in a stable environment. Printing Industries of America offers products that verify proper viewing conditions or allow individual users to determine their sensitivity to color differences. QC devices help to improve customer relations by confirming the color expectations of the client so that each job is produced to their liking with the least amount of approval steps and waste for the printer.
A viewer’s color tolerance, though normally subjective to each individual viewer, can in fact, be quantified. The Pilot Color Tolerance Exercise helps to determine an individual’s standard for color acceptability based on their preferences. Some color vision products challenge the viewer to discriminate between hues such as the Farnsworth-Munsell 100 Hue Test, and others like the HRR Pseudoisochromatic Test detect if the viewer suffers from a color vision deficiency.
Lighting conditions can also affect the way that color is viewed. Not all light is the same temperature or intensity, therefore, controlling this variable when evaluating color will produce more consistent results. The graphic arts standard for color viewing is 5000K, and products like the RHEM Light Indicator alert the viewer when the lighting conditions do not meet that standard.
