Manufacture method of master embodying rainbow holographic image and special-purpose holographic image

Abstract

A method for preparing a master plate with rainbow holographic images and special holographic images comprises the following steps: (1) splicing a rainbow holographic plate and a special holographic plate together to form a spliced plate; (2) agglutinating the spliced plate obtained from step (1) onto a circular roller to form a printing roller; (3) pressing the printing roller onto the side of aplastic membrane with a carrier, so that holographic image information on the spliced plate is copied onto the carrier of the plastic membrane; (4) electroforming a layer of nickel on the carrier to form a nickel-metal layer, and then stripping the nickel-metal layer from the plastic base material, so as to obtain the master plate with the rainbow holographic images and the special holographic images. In the invention, since the spliced plate is agglutinated on the circular roller, and the base material is wrapped on a pressing roller at the time of pressing, that is, the holographic image information on the splicing plate is copied onto the base material through a method of pressing a round body with another round body, large-sized spliced plates can be used to adapt to the characteristics that the rainbow holographic plate is large in breadth and to splice the rainbow holographic images and the special holographic images together.

Description

technical field [0001] The invention relates to a method for making a stamping master, in particular to a method for making a master including rainbow holographic images and special holographic images. Background technique [0002] Rainbow technology is a holographic technology that records a hologram by taking a photo with a laser at one time, and reproduces a monochromatic image with white light illumination. Special image holography technology is a kind of holographic technology that uses laser light to record bit by bit on the carrier after digital encoding, and forms corresponding patterns and characters on the carrier. After different coding, it can be recorded on the carrier. Different patterns and text.

Problems solved by technology

[0003] At present, in the field of rainbow holographic plate making, usually only a simple rainbow holographic plate can be produced; while in the field of special image holographic plate making, firstly make a small special image holographic plate, and then use an imposition machine to assemble it on the plastic plate to form a large plate. However, because the imposition machine generally adopts a flat pressing method (that is, the splicing plate is flat when copying, and the substrate is also flat) or a flat pressing round method (that is, the splicing plate is flat when copying, and the base material is wrapped on the roller). ) to copy the holographic image information on the mosaic plate to the substrate, so that the area of ​​the mosaic plate is limited, such as the area of ​​the mosaic plate in the flat pressing method is generally not more than 150mm×150mm, and the area of ​​the mosaic plate in the flat pressing round method is generally No more than 150mm×50mm, and the rainbow holographic plate has a large format, generally 780mm×650mm or even larger. Therefore, the mosaic area of ​​the rainbow holographic plate and the special image holographic plate is quite large. The rounding method cannot copy the holographic image information on the mosaic plate to the substrate, and cannot form a large plate containing rainbow holographic images and special holographic images, so that rainbow holographic technology and special image holographic technology cannot be applied at the same time
