Problems solved by technology

However, once a new product is printed or a new operating device is encountered, the operator usually cannot accurately judge whether to increase or decrease the amount of ink, so that a good printing effect cannot be achieved
In this case, it will usually result in waste of paper and ink, resulting in increased printing costs and reduced production efficiency.

Abstract

The invention relates to an ink control method and device for a printed matter. The method comprises the following steps: obtaining a preset number of printing proofs, wherein the printing proofs are determined according to the printing pressure, the type of printing oil, the use amount of paper and the inking amount; measuring and recording chromatic values and density values of the printing proofs; establishing a relation model between the chromatic values and the density values which are obtained through measurement, and calculating the optimal density value based on the minimum chromatic aberration; determining at least one candidate density value within a density value standard range according to the optimal density value, and calculating a derivative value of a chromatic aberration function corresponding to each candidate density value; and increasing or decreasing the current ink amount according to the obtained derivative values of the chromatic aberration function. The ink control method provided by the invention can accurately judge whether to increase or decrease the ink amount at the present, so that the printing quality of the printed matter is improved, and the cost in a printing process is saved.

Description

technical field [0001] The present application relates to the technical field of printing quality control, in particular to an ink control method and device for printed matter. Background technique [0002] In the actual printing production process, controlling the amount of ink is the main means for machine operators to control the color difference of printed matter. [0003] At present, operators mostly rely on experience to control the amount of ink on printed matter. However, once a new product is printed or a new operating device is encountered, the operator usually cannot accurately judge whether to increase or decrease the amount of ink, so that a good printing effect cannot be achieved. In this case, it will usually cause waste of paper and ink, which will lead to increased printing costs and reduced production efficiency. Contents of the invention [0004] The purpose of the present application is to provide an ink control method and device for printed matter, w...
