Printer test pattern10/13/2023 ![]() ![]() ![]() ![]() The calibration target includes a large number of patches generated from combinations of printer colorants, and may repeat some of those patches either on the same sheet or on a plurality of sheets at positions on the sheet which are spatially distinct.ฤก. A method of calibrating the response of the printer to an image described in terms of colorimetric values, including the steps of: a) setting printer parameters b) deriving a printer response characteristic by printing a calibration test from device dependent printer signals stored in a device memory, the calibration image including a plurality of color patches, some of which may be repeated at a plurality of locations on the test image at spatially disparate locations selected to keep local printer non-uniformities from affecting both locations c) measuring printer response characteristics in device independent terms d) generating a memory mapping of device independent colors to printer responses for subsequent use in printing images defined in device independent terms. ![]()
