Embodiment 1

[0046] Such as figure 1 As shown, white ink is sequentially printed on the PET material by screen printing technology to form a white ink layer 4, a black reserved ink is printed to form a retained ink layer 2 close to black, and a gray ink is printed to form an ink layer 3 to be engraved. Wherein, the printing times of allocating black reserved ink is twice. The mass-to-number ratios of C, M, and Y inks in the prepared black reserved ink are: 55 parts of cyan ink, 45 parts of magenta ink, and 15 parts of yellow ink. The mesh number of screen printing is 300 mesh; the above-mentioned cyan ink, magenta ink, yellow ink, white ink and gray ink adopt UV ink, and use UV drying after printing each layer.

[0047] After printing, the fiber laser engraving machine is used to engrave the gray ink layer 3 to be engraved according to the designed graphic, and the exposed part is close to the black reserved ink layer 2; wherein, the fiber laser wavelength is 1-2 microns, The power of la...

Embodiment 2

[0049] Such as image 3 As shown, on the PC material, the white ink is printed sequentially by screen printing technology to form a white ink layer 4, the black reserved ink is printed to form a retained ink layer 2 close to black, the pure black ink is printed to form a protective ink layer 5, and the white ink is printed An ink layer 3 to be engraved is formed. Wherein, the printing times of allocating black reserved ink is twice. The mass-to-number ratios of C, M, and Y inks in the prepared black reserved ink are: 35 parts of cyan ink, 25 parts of magenta ink, and 35 parts of yellow ink. The screen mesh number of screen printing is 380 mesh; the above-mentioned cyan ink, magenta ink, yellow ink, white ink, and pure black ink use UV ink, and each layer is dried by UV after printing.

[0050] After printing, the fiber laser engraving machine is used to engrave the white ink layer 3 to be engraved according to the designed graphic, and the exposed part is close to the black ...

Embodiment 3

[0052] On the PET material, white ink is sequentially printed by screen printing technology to form a white ink layer 4, a black reserved ink is printed to form a retained ink layer 2 close to black, and a gray ink is printed to form an ink layer 3 to be engraved. Wherein, the printing times of allocating black reserved ink is twice. The mass-to-number ratios of C, M, and Y inks in the prepared black reserved ink are: 60 parts of cyan ink, 50 parts of magenta ink, and 10 parts of yellow ink. The mesh number of screen printing is 300 mesh; the above-mentioned cyan ink, magenta ink, yellow ink, white ink and gray ink adopt UV ink, and use UV drying after printing each layer.

[0053] After printing, the fiber laser engraving machine is used to engrave the gray ink layer 3 to be engraved according to the designed graphic, and the exposed part is close to the black reserved ink layer 2; wherein, the fiber laser wavelength is 1-2 microns, The power of laser engraving equipment is ...

Abstract

The invention relates to mixing black maintaining ink, an ink layer structure and a laser code carving method. The mixing black maintaining ink includes ink components of three-primary colors C, M andY, namely, cyan ink, magenta ink and yellow ink, and according to the mass part ratio, the cyan ink ranges from 30 parts to 60 parts, the magenta ink ranges from 20 parts to 50 parts, and the yellowink ranges from 10 parts to 40 parts. The ink which is obtained through mixing of the three-primary colors C, M and Y and is macroscopically black is adopted for replacing pure black ink, the dark inklayer of images-texts is obtained through mixing, and therefore the laser carving removal complexity difference of different ink layers is formed conveniently; and the problems that shallow ink layers are subjected to laser carving removal and dark ink layers are shown are solved, and the code carving effect with multiple colors mathaced is achieved through the principle.

Description

technical field [0001] The invention relates to the technical field of laser engraving, in particular to a method for preparing black retention ink, ink layer structure and laser engraving. Background technique [0002] Traditional printing is to present graphics and texts by superimposing ink layers. The advantages are simple equipment and many types of color matching, but the disadvantages are slow production speed, polluting the environment, high labor costs, complex production processes, and difficulty in changing dynamic information. [0003] The advantages of digital printing are fast printing speed and convenient image and text change, but the disadvantages are high cost, poor ink retention and poor wear resistance. [0004] Under the action of laser, the upper ink layer absorbs energy until it is saturated and vaporized, while the lower layer absorbs insufficient energy and is not damaged by the laser, which can realize the engraving effect of engraving the upper lay...
