ABSTRACT:
A print bar color printing system wherein exposure occurs through previously deposited color toner is compensated for light absorption in the previously deposited toner by selectively increasing the output of the print bar during a pixel time interval. Each time interval is divided into sublines which are available for applying image data. One subline transmits image data corresponding to the color of the image to be exposed at the photoreceptor surface, while the second subline carries information as to previously exposed and developed color images which overlap the subsequent image. The print bar is then selectively addressed to form the main color image with a pulse of relatively long duration, or duty cycle, followed by a pulse having a relatively short duty cycle. The second or third pulses represent the additional exposure level needed to compensate for light absorbed by previous color toners formed on the belt during the earlier development process.
