Blanket knowledge and holographic printing

Printing blankets are a key element in obtaining high-quality prints. All types of blankets have the same structure: the bottom layer and the surface layer. The bottom layer is composed of layers of fabric fibers, each layer is independent, and there is a layer of elastic material between the two layers to control the stretchability of the blanket. This makes the blanket porous and also has a certain degree of elasticity.

The surface layer is different according to the manufacturer, may be composed of several layers of elastic materials, each layer has its own physical properties, and then these material layers with different physical properties are combined together. Afterwards, the combined blankets are wrapped on a roller, finely stretched, and finally hardened into the oven.

The difference between blankets is very large. Different surface structures, profiles, hardness, and compressibility make the processing process different. The most critical element of the blanket - the surface layer should have the ability to obtain maximum and minimum ink from the plate without damaging the image, while at the same time the ability to transfer these inks to the printing material as much as possible, and at high speed in the case of.

What is holographic printing

Holographic printing is an anti-counterfeiting printing technology developed using laser holographic imaging technology. A three-dimensional model is illuminated from different angles with a laser beam and reference light separated from the laser beam. The light reflected by the model passes through a slit to form interference fringes containing the model holographic information. This interference fringe was recorded on a photographic film, turned into a nickel plate, and pressed on an aluminized film to reproduce the model holographic pattern under normal light. This is the principle of holographic printing.
