Abstract
A color correction method is provided for an electronic printing system that results in a color print that is made as close as possible to what an operator actually observes on a monitor screen (What you see is what you get). The printing system includes a computer, a color printer, and a color monitor. A calibration is automatically performed by the system's computer through the use of calibration software, a series of test patterns stored in the computer memory, a monitor calibrating device, and a scanner equipped with color trichromatic measurement capabilities.
