Embodiment Construction

[0046] figure 1 Shown are test elements 1 and 2 according to the prior art, which are used, for example, to obtain characteristic data in accordance with ISO 12642-2:2006. This involves test elements for the CMYK printing process. For example, the manufacturer can replace these test elements with special test elements, which are especially necessary when using spot colors.

[0047] The test elements 1 and 2 are constructed from the color zone 3, which must be distinguished as a whole: the uncovered color zone 4, that is, the white color zone 4, the color zone 5 with mixed components produced by overprinting of different printing colors, and the use of one for each The full-tone color zone 6 produced by the sole printing color 100% coverage and the hue value color zone 7 made of only one printing color, wherein the basic hue value of the constituent color zone coverage of each printing color can be between 0 and 100% between.

Abstract

The method involves printing a test element (10) with number of color fields (3-7) on a print material. The tone values and dot gain curves for the printing process are determined such that the correction curve is determined for obtaining the characterization data of printing process. Independent claims are included for the following: (1) test element for determining characterization data; and (2) device for determining characterization data.

Description

Technical field [0001] The present invention relates to the technical field of electronic copying and to a method for determining characteristic data used in a printing process. First, at least one test element with a certain number of color zones is printed on a substrate, and at least one type of printing The hue values ​​of the colors are correspondingly allocated to these color regions, the color regions of the at least one test element are spectrally measured by a measuring instrument to obtain measurement results, and these measurement results are stored as actual spectral data. Background technique [0002] In plate-making technology, printed manuscripts for printed pages are produced, which contain all the elements to be printed such as text, graphics and images. In color printing, an independent printing manuscript is generated for each printing color, which contains all the elements printed in the corresponding color. In four-color printing, they are the printing color...
