The UV printer has been able to print the glossy effect of the varnish, especially the 3D embossed pattern made with the UV printer, and then print a layer of varnish with the printer, the effect is the best. How does a UV printer print out the varnish effect? Is it necessary to add a device to the machine? Don’t worry, after reading this article, you will know the truth about printing varnish.
Printing principle of UV printer:
The UV printer uses a piezoelectric method to print ink onto a material through a precision nozzle to form a pattern, and the pattern is set to be imported into the printing software. The computer starts printing and the data is transferred to the printer to complete the work. There are a variety of print options available in the print software that can be adjusted to print only one color (red, yellow, blue, black, white) or just color. The most commonly used 3D embossing effect of UV printers is to print white + black to draw the embossed spot color area and then print a white + color.
The principle of the UV printer printing varnish effect is the same. Add a separate print head for printing varnish on the printer. The printing software has the function of printing varnish. The varnish function can be activated to complete the varnish effect. Among them, varnish can realize partial printing and global printing. It can print varnish or white + color + varnish synchronous printing. Generally, it is white + color + varnish synchronous printing function, so that UV printer can be completed again. The product is made, and the bright surface processing of the product is mostly used to print the varnish function separately, and the varnish is finished once.
There are three common processes for UV varnish:
1. Manual varnish, using a spray gun to manually spray oil onto the material, requires uniform spraying of technology.
2.UV printer varnish, suitable for local or small surface varnish. If the large format will affect the working efficiency of the UV printer, the thickness of the glazing oil is not so good.
3. Varnishing varnish, suitable for any material, varnish effect is adjustable, high efficiency. If it is within the budget, it is recommended to buy one more varnish machine, especially in the home improvement background wall industry. The multi-production efficiency requirements are higher and more applicable. The billboard industry and other small handicraft processing industries generally use UV printers directly on the varnish.
