Abstract

Disclosed is a technique to reduce the gloss associated with the solid area print samples generated in a IBM 3900 non-impact printer. This is accomplished by a surface modification of the non-compliant hard teflon hot roll through a glass bead impinging (burnishing) technique. By adjusting the pressure of the impingement of beads, the print gloss level can be controlled.

Reduction of Image Gloss and Improvement of Print Quality

      Disclosed is a technique to reduce the gloss associated with
the solid area print samples generated in a IBM 3900 non-impact
printer.  This is accomplished by a surface modification of the
non-compliant hard teflon hot roll through a glass bead impinging
(burnishing) technique.  By adjusting the pressure of the impingement
of beads, the print gloss level can be controlled.

      The benefits derived from the hot roll surface modification
over 1.5 million feet of running can be summarized as follows:

1.  Improved the print solid area uniformity
2.  Enhances the fuse quality of print samples
3.  Reduces the print gloss from 13.10 to 4.95 units, thereby
    producing a matte finished print samples.

      The reduction in gloss was very crucial to Barcode printing as
glossy prints have higher failure rates during scanning due to
specular reflection.
