| ANSI (American
National Standards Institute), a U.S. member of the International
Standards Organizations (ISO) that develops voluntary standards
for business and industry. IT8 is a set of standards developed
by the ANSI committee governing color communications and control
specifications (Romano). IT8 standards cover RGB, CMYK, scanning
targets, and multivendor calibration (Romano).
An IT8.7/3 target is a
printed reflection target that can be used to obtain the color
gamut achievable by the fingerprint test. The target can be
read by either a colorimeter or by a spectrophotometer. Many
devices exist today that will even automate the process of reading
and interpreting the target generating a color profile of the
achievable color gamut for each fingerprint test.These color
profiles are governed by the ICC (International Color Consortium).
They can be attached to color halftone files thus optimizing
the color balance of the printed halftone itself for a particular
fingerprint. Color profiles have helped to attain consistency
within the printing process by permitting predictable color
reproductions. It is very important to understand that a separate
profile is created from each fingerprint. Failure to utilize
the appropriate profile, may result in unpredictable print.
If used correctly, ICC color profiles can be a powerful tool
aiding all types of printers.
