[0029] Example: Making a large-size holographic master of a hologram of a soft-packed cigarette packet
[0030] Task requirements: It is required that the effective molding area of the spliced holographic master is 775×619.8mm, the size of the unit holographic pattern (that is, the small cigarette case) is 155×103.3mm, a total of 30 unit holographic patterns, forming a 5×6 The matrix of the unit holographic graphics, plus the size of the holographic master after the frame is 1000×800mm, the purpose of the frame (trimmed nickel plate) is to meet the requirements of subsequent processes, such as electroforming or molding.
[0031] The manufacturing method is:
[0032] 1. Copy 30 pieces of holographic patterns (that is, unit holographic patterns) of small cigarette packs by electroforming, that is, copy 30 nickel plates with holographic patterns of small cigarette packs. The thickness of the nickel plates can be selected to be about 55 microns, but each The thickness differe...
