Problems solved by technology

The disadvantages of this technology are: 1) It needs to position each piece of sheet-fed paper and web, so the registration speed is slow and the efficiency is low; 2) This technology is difficult to register; 3) Only Can register a specific pattern, low production efficiency
This method is to perform multiple positioning printing on a roll, which is not suitable for holographic overprinting

Embodiment 1

[0026] Such as figure 1 As shown, the roll substrate 1 of plastic products or paper products, each group of specific patterns 1-2 corresponds to a cursor I1-1, each specific pattern 1-2 is the same, and has an overprint area on the specific patterns 1-2 1-3;

[0027] Such as figure 2 As shown, each holographic pattern 2-2 on the reel holographic anti-counterfeiting film 2 corresponds to a cursor II2-1, the holographic pattern 2-2 is similar in shape to the overprint area 1-3, and the holographic pattern 2-2 is slightly larger than the overprint area 1-3 3.

[0028] The cursor distances on the roll substrate 1 and the roll holographic anti-counterfeiting film 2 are equal. During overprinting, one roll of substrate 1 corresponds to three sets of same roll holographic anti-counterfeiting films 2 at the same time.

[0029] Such as image 3 As shown, the roll holographic anti-counterfeiting film 2 is placed on the unwinding shaft I3, and enters the overprinting device 5 throu...

Embodiment 2

[0031] Such as Figure 4 As shown, when the web 1 has different specific patterns 1-2 and 1-2', each group of specific patterns 1-2 has a cursor I1-1, and each specific pattern 1-2' has a cursor I1-1 Cursor I1-1', corresponding as Figure 5 As shown, at this time, the roll holographic anti-counterfeiting film 2 must also have different holographic patterns 2-2 and 2-2', each holographic pattern 2-2 has a cursor II2-1, and each holographic pattern 2-2' There is one cursor II2-1'. During overprinting, the specific patterns on the roll substrate 1 correspond to the holographic patterns on the roll holographic anti-counterfeiting film 2 respectively, that is, the specific pattern 1-2 corresponds to the holographic pattern 2-2, and the specific pattern 1-2' corresponds to the holographic pattern. 2-2' one-to-one correspondence. Wherein, the cursor distance of the cursor I1-1 on the roll substrate 1 is not equal to the cursor distance of the cursor II2-1 on the roll holographic a...

Abstract

The invention discloses a holographic positioning overprinting method between coils and belongs to the field of anti-counterfeiting printing technology. Substantially, a holographic pattern on a drum holographic anti-counterfeiting film is positioned and overprinted on a drum printing stock; and the method is characterized in that: 1) each specific pattern or each group of specific patterns on the drum holographic anti-counterfeiting film and the drum printing stock have an axial positioning cursor; 2) the drum holographic anti-counterfeiting film and the drum printing stock are put into an overprinter unwinding device, respectively pass through a traction roll and enter an overprinting device; after overprinting, the anti-counterfeiting film is stripped and winding is performed; and before overprinting, the two kinds of drums are respectively horizontally and axially positioned and then subjected to continuous overprinting. The method can realize accurate and continuous overprinting between the coils, improve overprinting accuracy and efficiency and reduce the reject rate.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting printing, and in particular relates to a method for holographic positioning and overprinting between roll materials. Background technique [0002] At present, positioning holographic overprinting on the roll substrate can only achieve one-way positioning transfer, that is, the position of the holographic pattern on the substrate is fixed, but the content is random. In this way, the consistency of the holographic pattern in each printing unit of the substrate cannot be achieved under the prior art, that is to say, the holographic pattern and the specific printing pattern cannot be accurately overprinted in each printing unit. [0003] In recent years, the existing technology has also developed, especially in cigarette packs, but it can only realize accurate overprint positioning printing of sheets, and cannot complete continuous overprint printing of rolls. [0004] For example: the Ch...
