Abstract

Abstract An apparatus and method for adjusting color and gray balance in a color printer, wherein a multicolored output sheet (180) including a set of printer color balance adjustment instructions for performing color balance adjustments processor is produced by the print engine. A processor provides a color balance judging indicator, from a scanned test pattern sheet in the case of a copier or from a memory electronically storing a test image. A controller is used to transmit the set of printer color and gray balance adjustments to the processor.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 84 words
A printing system adapted to print multicolored indicia on sheets, comprising: a processor, responsive to receiving a set of printer color balance adjustments, for providing a color balance judging indicator ; a controller for transmitting the set of printer color balance adjustments to said processor; and a print engine, associated with said processor, for printing a multicolored output sheet (180) including a set of printer color balance adjustment instructions on performing color balance adjustments with said controller according to the color balance judging indicator.
Claim 2
Dependent Claim 38 words
The printing system of claim 1, wherein the printer color balance adjustment instructions printed by said print engine includes a set of gradated color balance information for indicating a magnitude of the color balance adjustments to be performed.
Claim 3
Dependent Claim 65 words
The printing system of claim 1, wherein: said processor, responsive to receiving a set of printer gray balance adjustments, provides a gray balance judging indicator; said controller transmits the set of gray balance adjustments to said processor; and said printer engine prints a set of printer gray balance adjustment instructions for performing gray balance adjustments with said controller according to the gray balance judging indicator.
Claim 4
Dependent Claim 40 words
The printing system of claim 3, wherein the set of printer gray balance adjustment instructions printed by said print engine includes a set of gradated gray balance information for indicating a magnitude of the gray balance adjustments to be performed.
Claim 5
Dependent Claim 27 words
The printing system of any one of claims 1 to 4, wherein said processor comprises an electronic data storage member for generating the color balance judging indicator.
Claim 6
Dependent Claim 34 words
The printing system of any one of claims 1 to 4, wherein said processor comprises an image scanner for generating the color balance judging indicator according to a test pattern image on a sheet.
Claim 7
Dependent Claim 37 words
The printing system of claim 1, wherein: said processor provides a pantone color status indicator; and said print engine prints a pantone checking color output sheet for indicating a pantone color quality output of said print engine.
Claim 8
Independent Claim 79 words
A method for adjusting color and gray balance of a printing system adapted to print multicolored indicia on sheets, comprising: obtaining a color balance judging indicator from a print engine; outputting a multicolored sheet from a print engine, with the multicolored sheet including a set of printer color balance adjustment instructions on performing color balance adjustments to the print engine; and performing a set of printer color balance adjustments according to the set of printer color balance adjustment instructions.
Claim 9
Dependent Claim 37 words
The method of claim 8, further comprising: determining a magnitude of the color balance adjustments to be performed according to a set of gradiated color balance information included on the multicolored sheet outputted by the print engine.
Claim 10
Dependent Claim 64 words
The method of claim 8, further comprising: obtaining a gray balance judging indicator from the print engine; outputting a multicolored sheet from the print engine, with the multicolored sheet including a set of gray balance adjustment instructions for performing gray balance adjustments to the print engine; and performing a set of gray balance adjustments according to the set of printer gray balance adjustment instructions.
