UV printing what is it?
It is one of a kind of digital inkjet printing with the use of specific inks that harden under the influence of radiation of special ultraviolet lamps; there is a process of photopolymerization. UV printing is opaque printing, that is, a thin film is formed on the printed material, the ink is not absorbed by the material itself. Images can be applied on almost any basis by pre-treating the surface with a special primer and removing static electricity from the work surface. You can also print on a ribbed surface, such as two-ply corrugated cardboard. Among the materials on which you can print a color layout, there are some that we had never dreamed of before, such as leather, wood, carpet, linoleum, rubber.
Application of UV printing (business areas)
In advertising. Currently, this type of printing is widely used in the production of advertising products, POS materials such as mobile phones, growth figures, anti-theft door covers, solid posts, headings and more. Printing can be done on materials such as corrugated cardboard, micro-corrugated cardboard, PVC plastic and other sheet and roll materials. UV printing is also becoming more prominent in the souvenir industry, with the help of which you can print on covers for phones, flash drives, pens, pulp, so you can make multicolored prints, even on a laptop or tablet.
Interior decoration. Ultraviolet printing also has a strong foothold and interior decoration applications include stretch ceiling printing, kitchen and bathroom panels, printing and theatrical decoration. Printing is possible on materials such as tile, laminate, linoleum, carpet and more.
Architecture and construction. Modern construction companies and architects also use UV printing in their work. These are glass printing, composite printing, porcelain stoneware and tile.
UV-resistant, UV-printing advantages
Modern inks for UV printers are captured in the process of polymerization under the influence of ultraviolet radiation. This process is irreversible, making the print very saturated, bright, resistant to atmospheric phenomena, requiring no additional protection, such as laminating. Unlike solvent and eco-solvent inks, UV-printed images have good resistance to mechanical stress (abrasion) and reactive substances.
Ultraviolet ink cures, dries almost instantly, and as a result, the range of printing materials is very large.
Another advantage is that you spend a minimal amount of time printing without any prep work, such as film output, dies, plates, and more.
Types of printing equipment
Roll-up UV printers. This equipment, as well as solvation and eco-solvent plotters, are specially designed for printing only roll materials popular in the advertising environment, such as banner, mesh, paper, film, backlight, and more.
UV tablet printers. This type of equipment is intended for printing precisely sheet materials, various types of plastics, corrugated cardboard, foam and the like. The peculiarity of such a printer is the immobility of the table on which the material lies, and only the printing carriage in motion. The advantages of this type of printing are the high accuracy of printing. This kind of printer can handle heavy materials. This type of equipment is suitable for printing on glass, mirrors, wooden furniture items.
Combined or hybrid UV printers. This type of equipment has a vacuum-powered movable table, making it easy to print both traditional roll materials and non-heavy sheet materials on this printer; for the latter the machine is equipped with sliding tables with rollers for feeding material.
RPK "PrintStandard" uses hybrid UV printers in its production. To achieve the best print quality (halftones, gradients) we use six-color printing with different materials.
