Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0023] Multiple hanging screen printing process of the present invention, it comprises the following steps:

[0024] Step 1: During pre-press plate making, divide the patterns in the layout according to their characteristics;

[0025] Step 2: Rasterize the partitioned patterns and output sub-files;

[0026] Step 3: Compiling and combining the sub-files into a complete layout, and then rasterizing and outputting to the electronic film;

[0027] Step 4: Output the ...

Abstract

The invention provides a multi-screen printing process comprising the following steps of: 1, partitioning patterns in a layout of a printed page according to characters during plate making before printing; 2, respectively rasterizing the partitioned patterns and outputting subfiles; 3, editing the subfiles, combining the subfiles into an integral layout of the printed page, rasterizing the subfiles again and outputting the subfiles to an electronic film; and 4, outputting the electronic film to a film or making a printing plate. After the patterns are partitioned, colors in all regions can be respectively adjusted into screentones most suitable for printing types, so that the picture quality is up to the optimized, and the problem of poor local printing effect caused by adopting the same screen type is avoided. Combination of different screentone types can be adopted on some color printed bills with anti-fake requirements under the condition that multi-color printing is not additionally provided, so that the effect of anti-fake scanning and color scanning imitation is achieved.

Description

technical field [0001] The invention relates to the field of printing, in particular to a printing process. Background technique [0002] Resolution is a parameter used to measure the amount of data in a bitmap image. Usually expressed as pixels per inch (Pixel per inch, abbreviated as ppi) and dots per inch (Dot per inch, abbreviated as dpi). Screen Resolution (Screen Resolution), also known as screen frequency, refers to the number of lines per inch of the screen used for printing images in the printing field, that is, the number of lines of the hanging network, expressed in lpi; for example, 150LPI refers to the number of screens per inch. Inch Plus has 150 network cables. The technical scheme of ordinary screen printing process, hanging net refers to the use of a certain resolution of the network cable frequency when outputting. For example, high-end printing generally uses 150-175lpi, and some high-end picture albums also use 200lpi-300dpi resolution. [0003] Halfto...
