Embodiment Construction

[0029] For other purposes and effects of the present invention, please refer to the embodiments shown in the accompanying drawings, which are described in detail as follows.

[0030] Please refer to Fig. 2 (A) shown, the manufacture method of master plate unit of the present invention is to utilize photosensitive type UV adhesive 31 to be coated on the master mold 20 surface of tool texture 21, and cover transparent plate 32 on UV adhesive 31, as It is made of PC or PVC material; make the UV glue 31 penetrate into the texture 21 completely to form the corresponding texture 311; irradiate UV light to make the UV glue 31 mature and harden, so that the UV glue 31 will be attached to the transparent plate 32; then make the UV glue 31 Separated from the master mold 20 , the texture 21 of the master mold 20 is completely copied on the UV glue 31 . Repeat this step several times to obtain several pieces of master units 30 with deep lines 311 .

[0031] As shown in the aforementioned...

Abstract

An embossed master plate with texture pattern and its plate assembly method, at least two master plate units with metal film on the back are attached to the surface of the silica gel substrate in a downward manner with lines; at the joints of these master plate units Apply UV glue on the top, the UV glue fills the gap of the seam, and partly penetrates to the surface of the texture; irradiates UV light, makes the UV glue on the master unit and in the seam harden, and makes each The chip master unit is combined into a large master; the master is separated from the silicone substrate; and the immature and hardened UV glue that seeps into the surface of the texture is cleaned. This invention proposes an innovative plate-making technology that is simple and takes into account the texture and seam flatness requirements of subsequent electroforming and embossing processes, so that when many master plate units are assembled into a large master plate, the seam has better flatness degree without affecting the grain structure on both sides of the seam.

Description

technical field [0001] The present invention relates to embossing masters, especially embossing masters with textured patterns. The invention also relates to a method for making the master and a method for grouping. Background technique [0002] Currently used in the manufacture of holographic pattern imprinting masters in the holographic texture pattern imprinting process, for example, Taiwan Patent Publication No. 384419 discloses a method of making a photomask using a computer-drawn grating pattern, and then using a semiconductor process to make a full-body pattern. The photo master is then electroformed into a nickel plate; the nickel plate is then used to replicate the finished plastic hologram. The above-mentioned technique of making a master using a semiconductor takes a lot of time and costs a lot. [0003] see figure 1 As shown, there is another cheaper and simpler method for making a master plate, which is to make a plastic sheet 10 and a master mold 20 engraved...
