Test pattern printing method, information processing apparatus and printing apparatus

摘要

The test areas are each printed with a different mixture of the ink colorants and serve as an indicator to show the degree of color deviation while the reference areas serve for visual comparison with their adjacent test areas. The variation in color mixtures is arranged so that by counting the pairs number of test and reference patterns until the pair with the best color uniformity between the test and reference area is found, a correction value is obtained to cancel the variation of the color of the colorants being used. An independent claim is included for apparatus for printing a test pattern.
