Abstract

Disclosed is a color printer which uses a CRT to print on photographic medium. The printer contains a uniformity EEPROM that corrects for brightness of each position on the CRT. If a position cannot be corrected, a blank code is placed in the EEPROM at the position, to blank the CRT at the position. Adjacent positions are intensified, or positions in the same column on other CRT rows are intensified to correct for the defective position. The printer also allows the uniformity information to be field updated by printing an entire page of each primary color, sending these pages back to the factory, scanning them into a computer system using a document scanner, analyzing each page, creating new uniformity data from the analysis, and sending this data back to the printer where it is loaded into the uniformity EEPROM.
