WHY STANDARD VIEWING

Producing and printing high quality color is a complicated process that demands accuracy and consistency. Far too often, incorrect or inconsistent lighting and viewing conditions result in communication problems during the color reproduction process. To combat these problems, the industry has established an International standard, ISO 3664:2000, to insure greater viewing consistency. When all participants involved in the color process view color under standard conditions, color communication is optimum. Any deviation from the standard can result in frustrating and costly errors.

Industry standards require that viewing conditions meet strict specifications with regard to: color quality, light intensity, evenness of illumination, viewing/illumination geometry, and surround conditions. Differences in any of these conditions can affect color appearance.

There are many factors that influence the way color is perceived. Individuals perceive color differently due to the complex nature of the human eye. When you combine this fundamental factor with the significant impact physical viewing conditions have on color appearance, the slightest variation in lighting and environment can produce MAJOR color shifts. The best way to guarantee that the color communication "chain" is functioning under accurate and consistent conditions is to require that all participants view color in a tightly controlled environment designed and manufactured in accordance with industry standards.*

Once this goal has been accomplished it is crucial that all viewing environments are routinely maintained to assure ongoing compliance with the standard. Accurate color viewing can only be achieved if all components of the system are operating at full potential.

Note: One critical system component that can significantly alter color perception and render a system "non-standard" is the D5000 fluorescent bulb. Aging and yellowing of D5000 bulbs create dramatic color shifts. Scheduled relamping of fluorescent bulbs is a very simple and cost effective way to insure standard viewing conditions.
