Embodiment 1

[0034] Embodiment one: see figure 1 , a method for pressing dark lines on a microporous substrate, comprising the following steps:

[0035] S1, make hot stamping plate, select copper plate as the hot stamping plate, and use engraving machine to engrave dot matrix on the hot stamping plate to form a hot stamping pattern, test the hot stamping plate to check the quality of the hot stamping plate;

[0036] S2, bronzing operation, select a microporous sheet (also called a microporous coil) with a thickness between 203-254 microns, preferably a 254 micron microporous sheet, and place the microporous sheet on the working platform; then , apply pressure and temperature to the bronzing plate, and the microporous sheet is hot-pressed by the bronzing plate until the anti-counterfeiting pattern on the bronzing plate is stamped out of dark lines on the microporous sheet;

[0037] Among them, the engraving pattern of the hot stamping plate is pressed into the paper at a depth of 25-30 μm,...

Embodiment 2

[0039] Embodiment two: see figure 1 , a method for pressing dark lines on a microporous substrate, comprising the following steps:

[0040] S1. Make the hot stamping plate, select the copper plate as the hot stamping plate, and use an engraving machine to engrave dot matrix on the hot stamping plate to form a hot stamping pattern, and test the finished hot stamping plate to check the quality of the hot stamping plate.

[0041] S2, hot stamping operation, the hot stamping plate is installed on the hot pressing machine, and the hot stamping machine drives the hot stamping plate to apply pressure and temperature.

[0042] Among them, a microporous sheet (also called a microporous coil) with a thickness of 203-254 microns is selected, preferably a 254 micron microporous sheet; then, the microporous sheet is continuously fed on the workbench and Carry out hot pressing.

[0043] During the work of the hot pressing frame, the number of hot stamping machines is 55-70 times per minut...

Abstract

The invention discloses a method for hot stamping of dark lines on a microporous substrate, and relates to the technical field of hot stamping of dark lines on substrates. The method comprises the following steps that S1, a gold stamping plate is manufactured, wherein a gold stamping plate material is selected, and an anti-counterfeiting pattern is engraved on the gold stamping plate material; S2,gold stamping operation is conducted, wherein a microporous sheet is selected and placed on a working platform, then the gold stamping plate is heated under pressure to perform hot stamping on the microporous sheet until the dark lines are formed on the microporous sheet completely through anti-counterfeiting patterns on the gold stamping plate by hot stamping, and the microporous sheet is a polyolefin microporous sheet. The method has the advantage that the production efficiency of sheets with dark lines is greatly improved.

Description

technical field [0001] The invention relates to the technical field of ironing dark lines on substrates, in particular to a method for ironing dark lines on microporous substrates. Background technique [0002] Anti-counterfeiting marks can be pasted, printed, transferred on the surface of the marked object, or marked on the packaging of the object, or marked on the appendages of the object (such as commodity tags, business cards and anti-counterfeiting cards), and have an anti-counterfeiting effect. [0003] At present, tube and anti-counterfeiting patterns on the market include tufted flowers, ground patterns, lace, etc. Among them, there is a kind of dark pattern on the market. After this kind of dark pattern is printed on paper, it is difficult to be observed under normal circumstances. Only when the substrate is backlit can it be observed by the human eye. [0004] In the prior art, such dark lines are usually engraved on the base material by means of laser engraving. ...
