The knowledge about Sticker Printing Process

Adopting roll-type sticker paper can complete multi-color printing, hot foil, laminating, die cutting, and collection at one time. This machine can use metal plate and resin plate for printing. Due to the building block structure, certain functional parts can be added or removed flexibly and conveniently according to the characteristics of the printed parts. The paper feeding structure and paper delivery structure of this machine are basically similar to those of a flexographic printing machine. The difference is that a mechanism that can control paper stepping and printing is added during the entire travel process. The agency requires strict time control and positioning control, otherwise it will affect the accuracy of overprinting.



The sticker printing China is to print trademarks, labels, and advertising layout patterns on special composite paper. The composite paper is a good quality surface paper (back) coated with sticker water, and then adhered to the surface and waxed on the bottom paper. When in use, as long as the backing paper is peeled off, the sticker paper printed with graphics and text can be directly pasted on commodities or other objects. Since the sticker printed matter has the advantages of easy peeling, strong stickiness, flexible use, wide adaptability, and convenient for continuous pasting, it is widely used in social and economic life and has a very broad market.


The direction of the paper during web-based China sticker printing is different from that of the general printing method. It realizes the overprinting by the axial jump movement. That is, three sets of printing plates are installed on the printing plate cylinder at the same time. When the sticker paper jumps on the printing platform, the printing plate cylinder reciprocates once in the horizontal direction to realize one color printing. To print three-color overprinted labels, the sticker paper must be moved three times on the platform to complete the entire page overprinting work.


The advantage of this printing structure is that it simplifies the structure of the equipment and reduces the volume of the machine. However, due to the short printing stroke, the printed product is not easy to dry, which is not conducive to the completion of large-area wet press and wet overprinting, and is more suitable for small area overprinting. Or overprint. From the perspective of the embossing structure, the printing quality of the circular flattening sticker machine is better than that of the flat flattening machine, especially in the aspect of printing the solid layout, which can achieve the good effect of uniform and thick ink layer. However, the sticker machine with a flat-pressing structure can easily make the layout (printed product) show an "oily" ink layer when printing a large-area solid plate, and the printing quality is not satisfactory, which is only suitable for small-format printing. After printing, the sticker products can also be online for bronzing, laminating, die-cutting, and slitting.


For sticker products that work online at the same time, the layout design should fully consider the characteristics of the equipment, and try to avoid large-area solid layout overprinting, so that printing, bronzing, and laminating can achieve better results.
