Summary:

Investigations spanning several years in the area of softproofing on display have identified the following potential barriers to achieving contract proof-quality on display:1.Correlation of CIEXYZ and CIELAB between hard copy measurements and display measurements, 2.Effects of flare, 3.Effects of resolution, 4.Absolute accuracy of measurement devices, 5.Absolute accuracy of calibration technology, 6.Impact of variations between manufacturers and between lots of the fluorescent tubes used for illuminating hard copy, 7.Effects of non-opaque paper, 8.Lack of robust system level control of profiles, calibration state, etc.Once these topics are addressed to an adequate level of precision, consistent matches can be achieved between contract proofs or press proofs and the corresponding image viewed on display for a wide variety of reproduction conditions ranging from high quality commercial printing to newsprint. Virtual Proofing is the term used to indicate contract proof-quality color accuracy on display achieved automatically on multiple displays even when they are compared side by side to each other as well as compared to a contract proof or press proof illuminated in a viewer. This paper will seek to describe the solutions necessary to overcome each of the barriers listed above, and to confirm that virtual proofing now has a strong technical foundation.
