Poor control of viewing conditions is the most common cause of color misalignment between hard copy proofs and virtual proofs.

The following factors should be considered when aligning colors that are displayed on a monitor with colors on a hard copy proof or press sheet:

  • Light sources that affect a user's color perception are:
    • Monitor backlighting
    • Viewing booth lighting
    • Contamination from ambient light
  • The monitor display is emissive while the press sheet is reflective. Color on a press sheet may look different under different lighting conditions, while color on a monitor is independent of room lighting conditions. Color on a monitor is dependent on the monitor's backlight.
  • The light level in the viewing booth must produce an overall brightness reflected from the press sheet that matches the brightness of the monitor display.
  • The Kodak Matchprint Virtual technology is optimized for the spectral output of lamps that are manufactured by Graphic Technology, Inc. (GTI) and JUST Normlicht, Inc. Lamps produced by any other manufacturer may produce color artifacts. The lamps must not be aged more than 2500 hours, and the brightness of the lamps must be adjustable with a dimmer control. Bulbs need to be used for 100 hours before they can be used for color-accurate viewing.

You are responsible for assessing and adjusting the viewing environment before using the Matchprint Virtual technology to compare monitor proofs to hard copy proofs or press sheets.

A Kodak Reference Proof kit is included with your purchase of onsite training (SUA). Use the kit's reference white sheet, reference proof, and profile to verify correct color and optimize your viewing conditions.

Overhead light fixtures

Ambient lighting, or overall illumination, can significantly affect the accuracy of color viewing. To reduce ambient room lighting, close curtains, install dimmers for lights, or use fewer bulbs.
In rooms where Matchprint Virtual is used, install CIE D50 (5000K) fluorescent halogen lamps that meet the IS0 3664:2000 graphics viewing standard. D50 illuminants such as GTI Graphiclite color viewing lamps are designed for color-accurate viewing.

If you are not sure whether your lamps meet the ISO standard, contact your lamp manufacturer.
