Calibration of PostScript-Based Color Reproduction Systems

This paper will present an overview of the variables involved in imagesetter calibration. It will describe some of the common methods used to control these variables in Postscript imagesetter. The emphasis in the presentation will be on the use of Postscript transfer routines to accomplish this purpose. Different approaches to managing transfer routines and the interactions of competing transfer functions will be discussed. This will include attaching transfer routines to individual documents, creating printer description files which include transfer routines and downloading the transfer routines into the imagesetter. The advantages of a device independent approach to calibration will be presented. This paper will also address those features of Postscript Level II which are related to imagesetter calibration. features of Postscript Level II which are related to imagesetter calibration.
