Embodiment 1

[0033] Using the locking screen pattern UV printing and coating technology of the present invention to make a milk powder can for ordinary packaging of 3 sections as an example, the hardness of the tinplate is T4, the amount of tin plating is 2.8 / 2.8, and the specification of the iron sheet is 0.23*802*7300, which includes the following steps:

[0034] 1) Locked texture data information processing

[0035] Analyze the level distribution and color tone data of graphic data files, select the appropriate locking area A, and generally select the midtone area with rich color tone levels; see figure 1 , figure 2 ;

[0036] Use the professional drawing software module Power Lock to draw the locked graphics in the locked area (the locked graphics can be personalized according to customer requirements, such as using customer LOGO), and make the locked graphics into an independent vector file;

[0037] Select the appropriate channel to lock the graphics that need to be locked. Genera...

Embodiment 2

[0051] Using the lock screen pattern UV printing and coating technology of the present invention to make a beverage can as an example, the hardness of the tinplate is T4, the amount of tin plating is 1.1 / 2.8, and the specification of the iron sheet is 0.20*860*1036, which includes the following steps:

[0052] 1) Locked texture data information processing

[0053] Carry out layer distribution and color tone data analysis on graphic data files, select the appropriate locking area, generally choose the middle tone area with rich color tone layers;

[0054] Use the professional drawing software module Power Lock to draw the locked graphics in the locked area (the locked graphics can be personalized according to customer requirements, such as using customer LOGO), and make the locked graphics into an independent vector file;

[0055] Select the appropriate channel to lock the graphics that need to be locked. Generally, choose a channel with a relatively high layer coverage, such as ...

Abstract

A locked reticulate pattern UV (ultraviolet) printing method includes following steps: 1) processing locked reticulate pattern data information, selecting a locked area, drawing a locked graph in the locked area by the aid of a professional cartographic software module, and manufacturing the locked graph into an independent vector file; selecting a channel to lock a graph needing to be locked; and respectively printing channels with locked information and channels without locked information into Postscript page description files, rasterizing the Postscript page description files and explaining the Postscript page description files into single-channel bitmap files; 2) realizing computerized direct platemaking, uploading the single-channel bitmap files to a computerized direct platemaking machine, and exposing and drying on a light-sensitive pre-coating section plate; 3), external coating; 4) UV printing; 5) solidifying; and 6) polishing. Reticulate pattern anti-fake information is inserted under the condition that appearances of products are not affected, troublesome procedures of traditional film publish are omitted, UV high-fidelity printing is adopted, and glossiness is good. In addition, fuel consumption and waste exhaust are relieved, and purposes of saving energy and protecting environments are achieved.

Description

technical field [0001] The invention relates to UV printing and coating technology, in particular to a method of UV printing and coating with locked screen pattern. Background technique [0002] Traditional iron printing adopts heat curing mode, using heat curing ink and gas drying room to dry ink, which consumes a lot of energy and emits a lot of waste gas, which is not conducive to energy saving and emission reduction. [0003] The traditional special screening method generally realizes the dot anti-counterfeiting by customizing the dot shape. Customizing the dot shape can realize the personalization of dot anti-counterfeiting, but it is easy to cause a large dot expansion rate and reduce the printing suitability of the product. [0004] The traditional pre-press plate-making process is graphic data information processing → RIP raster processing → making film film → drying traditional PS plate. Contents of the invention [0005] The purpose of the present invention is ...
