Abstract
A method and system for correcting a deviation in color balance in an image output device, without the need for performing a direct adjustment to the hardware. Image output devices may include printers, displays, or other image output devices. Deviation data may be derived from the output characteristics of every element color of an image output device, and stored at the image output device. A color correction device is provided which has the ability to receive the deviation data, and produce image data having a color correction based on this deviation data. The system can then communicate the color corrected image data to the image output device. The color correction system also may be configured to discriminate among a plurality of image output devices, with each image output device having the ability to store their own inherent output characteristics at the image output device.
