UV Crystal Label Printer coil digital printing machine cold transfer sticker machine
There is a hot spot in UV flatbed printers, and that is the crystal label. Crystal label is also called UV transfer sticker. Its predecessor is called pressure sensitive sticker. It is a kind of printing on the special release material, then covering the transfer film, and then using the film to transfer the pattern to the surface of the product. Surface graphic production process. At present, there are four mainstream production processes in the market: pure screen printing, screen printing + digital, AB film digital solution, and digital spray glue solution. UV printers can also be used for pattern printing of crystal labels.
When it comes to crystal labels, its feature is that it can be made in small batches or even one piece, and the pictures and texts can be left on the tear film. In addition to good pattern effects, it also has good scratch resistance and weather resistance, which is somewhat similar to the advantages of UV printers. At present, crystal labels are mainly used in packaging, marking, and special-shaped and irregular surfaces with poor printing efficiency using UV printers, such as products with cylindrical surfaces.
The difficulty of the crystal label is not the equipment, but the stable process. However, using a UV flatbed printer to produce graphics on crystal labels has obvious advantages over silk screen printing and transfer printing in terms of labor, environmental protection, and personalization. But crystal labels are not suitable for everything, such as tableware, hot water cups and other edible contact products, which are too rough, cloth, clothes, soft leather, etc. are not suitable. In addition, in the relatively harsh outdoor environment, there is also a risk of warping and falling off.
Some people once said that the appearance of crystal labels threatens UV printers, so it is still unreliable. As far as the current technological level and the actual needs of customers are concerned, mass production of crystal labels is still not suitable. In addition, since labeling relies on manual work, there are errors in labeling and positioning, so it is not suitable for products that have strict consistency standards. Each product and each process has its applicable fields and limitations. Regardless of the printing and production process, the crystal label is more like an art decoration.
