Abstract
Color profiling a media for a printer is a tedious and time-consuming process. Embodiments of the invention avoid the need for unnecessary color calibration and profiling by making use of similarities in color rendering that exist between various printers and their color behavior on a media, as well as the similarity of substrates. In this way, embodiments of the invention avoid the need to create output profiles when a system is already equipped with an adequate profile. This allows average users to get adequate quality color reproduction faster for less demanding day-to-day print runs.
Claims30
A method for automatic media color profile identification, comprising:
- selecting a media for use in printing on a selected printer for which a specific media color profile does not exist;
- executing a calibration and profiling procedure to identify similarities in color rendering between said printer and other printers, color behavior of media on said other printers, similarity of said media with other media by:
- printing a test target on said selected media;
- measuring the printed test target, wherein the test target comprises a plurality of patches;
- saving said printed test target measurement;
- based on said test target measurement, searching a database of existing media color profiles in said selected printer;
- for each of said existing color media profiles calculating a score, wherein said score is based on a difference between said test target measurement for each of the plurality of patches and on characteristics of said existing media color profiles, and wherein said score is a weighted score depending on a difference for each of the plurality of patches;
- returning a list of selected candidate media color profiles, wherein said selected candidate media color profiles are sorted in score order;
- and
- selecting and applying a candidate color media profile from the list as a media color profile for said selected media on said selected printer;
- wherein application of said selected candidate color media profile in said selected printer for said selected media makes it unnecessary to create additional color media profiles in said selected printer for said selected media.
