Accurate color judgement is dependent on proper lighting conditions. Industry-standard D50 (5000 Kelvin) light is used to ensure proper color communication between print buyers and suppliers when viewing color proofs.
The GATF/RHEM LIGHT INDICATOR will tell you whether or not your lighting conditions are suitable for color critical judgement. If you can see stripes on the indicator, lighting conditions are not suitable; if there is only a solid color the lighting meets industry specifications.
Cummings Printing can provide you with a GATF/RHEM Light Indicator which will help you verify that your viewing conditions meet industry specifications. To request your light indicator, contact your CSR or Sales Representative.
