THE EFFECT OF CALIBRATION ON SHORT-TERM REPEATABILITY AND COLOR DIFFERENCES IN ELECTROPHOTOGRAPHY

Abstract

The goal of every printing technique is to get a high quality, durable print, accurate color reproduction and possible repeatability. The aim of this paper is to test the influence of the calibration process on the short-term repeatability of the print, and to analyze the reproduced color difference, and how all this is affected by the printing process of electrophotography. The color difference values are predefined by changing the brightness value. The chromatic coordinates a and b remained unchanged. Three sets of sheets were examined, the  one where the calibration of the machine was done before printing of each sheet, the seconf where the calibration was the the first day of printing and third, where the alibration was completely ommited.
