Problems solved by technology

[0003] The disadvantage of laser holographic transfer paper in the prior art is that the transfer film will inevitably form a slit during the embossing printing process. Generally, the width of the slit is 0.1-0.5mm. In the process of transferring printing paper, the transfer paper seam
The transfer paper with slits will form unqualified products during the ink printing process, and these unqualified products must be manually sorted out, which is troublesome
In addition, the existence of seam will cause a certain waste of material

Embodiment

[0028] 1) Substrate: PET film: material transparent, flat, uniform thickness, error ≤ ± 10%, no water marks, stains, scratches, light transmittance 91% ~ 93%, its material is polyester material; PET The film thickness is 12-50um, and the length of each roll is about 5000 meters.

[0029] 2) Equipment: Except for version shaft II4, other equipment and its connection are the same as the prior art. There is a cooling area 4-1 on the plate axis II4, which adopts forced cooling methods, such as water cooling and air cooling, and the temperature of this area is lower than the imaging temperature of the imaging area 4-2.

[0030] 3) Preparation of the anti-counterfeiting holographic smooth film: firstly paste the working plate on the plate axis I 3 and plate axis II4 according to the prior art, the plate seam of the working plate on the plate axis I 3 is at any position, and the plate of the working plate on the plate axis II4 The plate seam is in the cooling area 4-1; according to ...

Abstract

The invention relates to laser holographical flow film, flow transfer paper and a production process, which belong to the technical field of laser holographical anti-counterfeiting printing. The invention has the technical key points that: PET film is printed twice; wherein, slots formed in the first mould pressing printing are right arranged in an imaging area in the second printing. Therefore, the prepared laser holographical flow film has no slots. By adopting the laser holographical flow film of the invention as the transfer film, the slotless transfer paper can be prepared through transfer printing. When the products of the invention are supplied to clients, the man power can be avoided from being wasted in removing the slots, the utilization ratio of the printing products for clients can be more greatly enhanced.

Description

technical field [0001] The invention belongs to the technical field of laser holographic anti-counterfeiting printing, and in particular relates to a laser holographic smooth flow film, smooth flow transfer paper and a production process thereof. Background technique [0002] Laser holographic transfer paper is a new type of material in the anti-counterfeiting packaging and printing industry. Its basic production process is to make a transferable holographic plastic film, and then transfer the laser information to the paper to make laser holographic transfer paper. The holographic transfer paper has changed the traditional process of embossing the hologram on the surface of the plastic film and then performing paper-plastic composite. Instead, it directly transfers the hologram to the surface of various papers, because it can use environmentally friendly base paper, so it can be used in It greatly reduces the pollution to the environment. In addition, it also has functions s...
