US Patent:

6623894, Sep 23, 2003

Filed:

Mar 14, 2001

Appl. No.:

09/808309

Inventors:

Dallas K. Pierson - Oakdale MN

Assignee:

Kodak Polychrome Graphics, LLC - Norwalk CT

International Classification:

B41J 2455

US Classification:

430 5

Abstract:

The invention is directed to compensating for imaging aberrations that result from repeated passes by an imaging laser array. The aberrations may result from swath lines formed by thermal heating and from the ruling and screen angle of the image. The techniques described herein reduce the undesirable aberrations in thermal laser generated images by breaking up and/or reducing the swath lines. In general, the techniques provide for overlapping swaths and providing masking for one or both passes that print the overlapped region.

Dallas K. Pierson - Oakdale MN, US

Assignee:

Kodak Polychrome Graphics, LLC - Norwalk CT

International Classification:

B41J002/47

US Classification:

347240, 347251

Abstract:

The invention is directed to techniques for compensating for imaging aberrations that result from repeated passes by an imaging laser array. The techniques provide for printing overlapping swaths and providing masking for at least one printing pass. The masks generally expand and contract the breadth of the printing swath.

Inventors:

Dallas Pierson - Oakdale MN, US

Assignee:

Imation Corp.

International Classification:

B41J002/455
G03C011/02
H04N001/21

US Classification:

347/233000

Abstract:

The invention is directed to compensating for imaging aberrations that result from repeated passes by an imaging laser array. The techniques described herein reduce the undesirable aberrations. In general, the techniques provide for printing a first line of image data and a set of contiguous lines as a function of the image data and a first mask. On a subsequent pass, these lines are overlapped. The line that overlaps the first line prints the image data again, but masked. The lines that overlap the contiguous lines print the image data normally.

International Classification:

G03F 3/08

US Classification:

358001900, 358518000

Abstract:

A system and a method are provided for maintaining accurate visual color performance of displays. In particular, various embodiments of the present invention described herein provide a system wherein partial color certification is incorporated into the calibration procedure. In the event that the partial color certification is out of tolerance, a full certification procedure is performed. If the full certification procedure is out of tolerance, the calculated errors of the certification procedure are utilized to perform an update to a baseline profile for the display. The updated baseline profile can either replace the existing baseline profile or can be concatenated with the baseline profile to preserve the baseline behavior of the display.
