Embodiment Construction

[0018] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0019] The present invention adopts the standard color test table printed on paper 1 under a certain printing condition, simulates and calculates the color value of the standard color test table printed on another paper 2 under the same printing conditions, and then according to this standard The color value of the color test table generates a characteristic file printed on paper 2, which is used to simulate the proofing of printing under this kind of paper.

[0020] Such as figure 1 As mentioned, the flow chart of the method for predicting the printing color characteristics of different printing materials in the present invention, the method for predicting the printing color characteristics of different printing materials in the present invention includes the following steps:

[0021] Step S1: Measure an...

Abstract

The invention discloses a prediction method of printing color features of different printing materials. The method includes the steps of S1, measuring and acquiring spectral reflectance of visible spectrum of each color block on a standard color testing table printed on first paper; S2, measuring and acquiring spectral reflectance phipaper1i(lambda) of visible spectrum of the first paper; S3, measuring and acquiring spectral reflectance phipaper2i(lambda) of visible spectrum of second paper; S4, under the same printing conditions, calculating spectral reflectance phicolor2i(lambda) of visible spectrum of the color blocks printed on the second paper according to the following formula, wherein i=380, 381...780; S5, calculating a printing feature file generated on the second paper according to phicolor2i(lambda), and using the printing feature file as a simulation target of sampling before printing so as to generate a printing sample.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a method for predicting printing color characteristics of different printing materials. Background technique [0002] The color of the printed matter is displayed by the ink attached to the printing material, and the paper and ink are the main factors affecting the color of the printed matter. In actual printing production, the ink is purchased by the printing factory according to its own needs, and the printing factory can control the use of ink, while the use of paper is affected by various factors such as the needs of users and the quality requirements of printed products, and it is often replaced more often. However, the paper has a great influence on the color. After changing the paper, the printed color will deviate accordingly. Then the previous printing characteristic file is no longer suitable for this printing. If it is applicable again, it will bring difficulties to ...
