Method for manufacturing holographic mother board by using electroforming imposition

Abstract

The invention relates to a method for manufacturing a holographic mother board by using an electroforming imposition, which is used for big-size unit holographs. The method comprises the following steps: firstly, fixing a plurality of nickel boards of unit holographs on a flat plastic bottom board by using double-faced adhesive tapes, and then, eliminating spliced joints between every two nickel boards of the unit holographs to manufacture a big-size holographic mother board. The invention has the advantages that the method can be used for splicing a large holographic mother board containing unit holographs in different unit sizes, the splicing speed is quick, the splicing precision is high, and the subsequent electroforming process can level up and eliminate the joints, thus the nickel boards can be combined together to form an ideal large holographic mother board.

Description

technical field [0001] The invention belongs to the field of holographic technology, in particular to a method for manufacturing a holographic mother plate by electroforming imposition for large-scale unit holographic patterns. Background technique [0002] At present, the technologies used for imposition at home and abroad can basically be divided into two categories: [0003] The first is a mechanical imposition machine for small-sized unit holograms, which uses the principle of hot stamping to splice small-sized unit holograms into a large-sized hologram master by hot stamping transfer. Due to the limitation of its principle and technology, at present, only small-sized holograms can be spliced, and the unit size is mostly within the range of 10 cm x 10 cm, and large-sized unit holograms cannot be spliced. [0004] The second is the silica gel imposition method. In principle, this method can splice large-sized unit holograms. It uses silica gel to replicate the unit holo...

AI Technical Summary

Problems solved by technology

However, due to the softness of the silica gel, it is difficult to control the cutting and splicing accuracy, and the imposition cycle is also very long (because the silica gel replication of each unit holographic pattern generally takes 24 hours), the process is complicated, and human factors have a greater influence

[0005] Therefore, for large-scale unit holograms, there is currently no ideal imposition method and machinery to splice holographic masters with large-size unit holograms.
