Embodiment Construction

[0046] The present invention provides a high-precision frequency modulation printing process, which includes the following steps:

[0047] Step 1. Determine the best printing plate dot value and printing plate output curve suitable for 10 micron frequency modulation dots, and standardize the best printing solid density, the best dot expansion value and the best ink overprint sequence process standard for 10 micron frequency modulation dot printing , In order to obtain the printing color gamut of high color rendering range.

[0048] 1.1 Design a printing quality data test version suitable for 10 micron FM dot printing.

[0049] Beta version such as figure 1 As shown, the layout basically covers 30 ink zones of the folio printing machine, and the size is 860×574 mm. The test version includes signal strips and test strips. The signal bar includes the gray balance detection section, the overall gray balance test color block, the four-color monochrome gradient test strip, the printing ...

Abstract

The invention discloses a high-precision frequency-modulated printing process which comprises the following steps of: 1. confirming an optimal printing plate screen dot numerical value and a printing plate output curve which are suitable for a 10-micron frequency-modulated screen dot and specifying optimal printing solid density, an optimal screen dot extending value and an optimal ink printing sequence standard which are suitable for 10-micron frequency-modulated screen dot printing to obtain a printing color gamut with high color gamut generation; and 2. carrying out printing work and data check strictly according to the process standard specified in the step 1 and all printing plate data obtained in the step 1 in an electronic color scanning and pattern adjusting procedure, a digital proofing procedure, a computer direct printing plate output and printing plate flushing procedure and a printing procedure of general printing work. In the high-precision frequency-modulated printing process provided by the invention, the traditional printing idea is eliminated, 1485 groups of color management data which are suitable for 10-micron frequency-modulated printing and a 10-micron frequency-modulated printing process specified standard are especially developed so ad to realize the 10-micron frequency-modulated screen dot printing.

Description

Technical field [0001] The invention relates to a frequency modulation dot printing process, in particular to a high precision frequency modulation dot printing process. Background technique [0002] At present, the commonly used screening methods in image reproduction in the printing industry are amplitude modulation screening and frequency modulation screening. Amplitude modulation screening is to keep the number and arrangement of the dots unchanged, and the color and density are controlled by the size of the dot diameter. In other words, in order to reduce the value of a given color in a specific area, keep the number and arrangement of the dots and reduce the diameter of the dots. The main technical feature of amplitude modulation screening is the four-color separation of the image (cyan, magenta, yellow, black). Different dot sizes are used to represent the shades of the image. The four-color dots are arranged to form a certain grid, and the four colors are overprinted int...
