Abstract
An engraving system and method having a non-volatile memory loaded with error coefficients. The error coefficients represent previously experienced differences between computed cell configuration values and corresponding configuration values for cells actually engraved. Sets of error coefficients are tabulated and stored in the memory along with associated setup parameters. Setup of the engraving system for a new job is swiftly accomplished by using values of the setup parameters to retrieve sets of approximate error coefficients, from which interpolated values are obtained. The interpolated values of the error coefficients then are used for calculating configuration control parameters such as AC gain, video gain and white offset.
