Description

Self-adhesive water-based labelless printing material

The present invention relates to the technical field related to decals (paper), and more particularly, to a self-adhesive water sticker filmless printing material.

Please refer to FIG. 9. The conventional water transfer decal (paper) uses the normal printing and forward rotation mode as an example. Its structure generally includes a watermark paper 91 and an epoxy ink layer 92 (standard film) stacked in this order. ), And a screen printing film oil layer 93; wherein the epoxy ink layer 92 (standard film) includes a primer gold oil layer 921, an epoxy white ink layer 922, and an epoxy colored ink layer 923 sequentially stacked. , And an epoxy-protected gold oil layer 924.

When the water transfer decal (paper) is to be transferred, it is necessary to soak the water for a few seconds to separate the watermark paper 91 from the epoxy ink layer 92 and the screen printing film oil layer 93 (separation function), and then pass through the ring. Oxygen ink layer 92 (standard film), the bottom rubber oil layer 921, the epoxy ink layer 92 is pasted to the processed object (not shown in the figure) at a preset position (repost processing) and pre-baked (about 80-90 degrees). After 20 to 30 minutes, the screen printing film oil layer 93 is peeled off, and different temperatures are set for heating and baking (commonly known as baking paint), and the low temperature is about 90 ~ 120 degrees Celsius. The pattern or text provided by the epoxy ink layer 92 is used to highlight the overall visual effect of the workpiece to be transferred.

However, when the conventional watermarking paper 91 is implemented in water transfer decals (paper), there are many defects that are caused by human scale in the process of stacking the epoxy ink layer 92 (standard film);

First, the conventional watermark paper 91 is made of long fiber paper with water-based adhesive coating, and the long fiber paper of watermark paper 91 has a siphon effect, and due to absorption Moisture causes the entire material of the paper and printing materials to shrink and expand under different temperature changes, and also makes the watermark paper 91 extremely poor in thermal stability. It cannot be baked at low temperature during the process of the epoxy ink layer 92 (standard film) color printing process ( Baking standard), is not conducive to color printing, the temperature and humidity control of the printing environment must be controlled (long fiber paper will shrink).

Second, because the watermark paper 91 (long-fiber paper) is easily affected by relative humidity, such as the printing environment humidity, screen printing primer layer, and ink layer will change the size stability of the paper material, so it cannot be heated and dried (baked standard) Therefore, in the process of registering the watermark paper 91, there is a concern that the registration is inaccurate. It is known that the size shrinkage of the watermark paper 91 is changing, and the misregistration of registration and registration accuracy during overprinting also causes the risk of longer printing time and process yield control errors.

3. In the process of stacking and printing the epoxy ink layer 92 (standard film) with the traditional watermark paper 91, the overprinting of the epoxy protective gold oil 923 will be forced to overprint the epoxy protective gold oil 923 after each layer of ink does not reach the effective dryness of the resin crystal to form a film. During the coating process, the surface of the label film loses its luster after baking or micro-bubbles occur during the coating process, which affects the aesthetics and yield of the label.

Fourth, because of the physical characteristics (water absorption, shrinkage) of watermark paper 91 (long-fiber paper), each layer of epoxy ink layer 92 (standard film) must be waited for the previous brush coating layer to dry completely after printing ( Crystallization into a film) before entering the next printing stack. To this end, a complete epoxy ink layer 92 (standard film), the printing process often takes 2 to 3 days to wait. Also, because the construction period is too long, in order to avoid the delay of the printing process, the predetermined order quantity (replenishment number) is printed in advance, so the phenomenon of "stock mark" often occurs. Of course, the printing factory will calculate the cost of the stock mark in the quote Medium, resulting in high purchase costs.

V. Another important issue of water transfer decals (paper) is that the labeling process (epoxy ink layer 92) must be immersed in water (de-labeling process) in order to make the watermark paper 91 and the primer gold Oil layer 921 is detached, epoxy ink layer 92 and screen printing film oil layer 93 Water will be attached to it (de-labeling procedure). When the epoxy ink layer 92 and the screen printing film oil layer 93 volts are attached to the workpiece to be transferred, an additional (rush) water process (slip film, positioning, If the process is not implemented, the epoxy ink layer 92 and the screen printing film oil layer 93 will cause blisters when they are left to dry, which will cause failure during baking and require rework to remove and rework.

6. The "screen printing film oil layer 93" of the conventional water transfer decal (paper) is mainly used as a carrier for the epoxy ink layer 92 to be transferred to the transferred object after the watermark paper 91 is detached. The screen printing film oil layer 93 has ductility and applicability, but the stretching is too soft, which easily causes deformation of the ink on the epoxy ink layer 92, and the distortion of the pattern makes it higher when the epoxy ink layer 92 (standard film) is transferred. Attrition rate. A common solution is to increase the film thickness and increase the stiffness (resin hardness), which in turn causes a delay in the original printing time (resin crystal formation time).

7. Printing with watermark paper 91 (long-fiber paper) as the substrate (traditional printing material), because the ink crystallizes into a film at a slow speed, it is not possible to speed up the process of registering through layer-by-layer hot baking during stack printing. Speed of printing. Therefore, the natural drying method is required, and the processing time will be greatly extended.

8. When the watermark paper 91 (long-fiber paper) is used as a printing material, as long as it is baked (about 50 ° C), the size shrinkage of the printing material will inevitably be formed. However, low-temperature baking paint is generally 90 ° C, and 80 ° C is the beginning of thermal bridge Temperature, which is also the temperature at which the epoxy ink layer 92 (standard film) is stacked, must be naturally dried, which is also the main reason for the extremely long working hours.

In view of the problems and shortcomings of the above-mentioned conventional techniques, one of the main objects of the present invention is to provide a self-adhesive water-stick labelless printing material. The new design of the structure can replace the water-marking paper and overcome the water-marking paper 91 (long Fiber paper) shrink deformation In addition, when it is implemented in the process of labeling (flower), it can greatly reduce the processing time, and it will not cause the loss of printing register accuracy and positioning errors due to shrinkage. , It has the convenience of self-adhesive paper operation, and more functions and characteristics of filmless mold operation reposting.

In view of the problems and shortcomings of the above-mentioned conventional techniques, the second main purpose of the present invention is to provide a self-adhesive water-based filmless label printing material. Through the new design of the structure, the printing material resistant to baking (baking) temperature is shortened The man-hours of subsequent ink stacking processes and the convenience of label film transfer.

According to the above-mentioned object of the present invention, a self-adhesive water sticker film-free label printing material is provided, which includes a laminated base paper, a low-viscosity isolation gold oil layer, and a release layer. The water-marking paper is replaced by a self-adhesive water-film-free labeling printing material, and provides preset release force and polarity response.
