How does uv printing work?

2023-01-04

I believe that many people have used UV printers, which have left good memories and beautiful pictures in our lives. UV printers are widely used in commercial printing, and even now they have entered thousands of small families. UV printers can print colorful things on different materials for us, so do you know how UV printers work? Now let UV printer manufacturer Hapond explain it to you in detail.

How does uv printing work?

 

1. When the UV printer is printing, the UV ink and the ultraviolet rays irradiated by the LED lamp undergo a curing reaction, so that the UV ink is instantly dried and attached to the surface of the object. In terms of printing time, it can be done immediately, without some baking and drying operations, saving manpower and time.

 

2. During the working process of the UV printer, there will be a positioning process. During the movement of the platform, the parameters of the x-axis and y-axis will be read to find the precise position to be printed. In the positioning of the X axis, it is mainly to read the numerical movement of the grating bar. On the Y axis, the movement is achieved by controlling the drive of the motor.

 

3. In terms of pattern processing, UV printers have special printing software. You only need to pre-set some printing effects for the pattern to be printed through the common ps drawing software. After simple processing, set the size to be printed, the position where the pattern needs to be printed, and whether to print relief and varnish effects through the printing software. .

 

What is the principle of uv printer?

 

The uv printer is a kind of printer, which belongs to the piezoelectric inkjet printing equipment. It uses uv photosensitive technology, uses computer input control, and uses inkjet technology and uv curing technology to achieve printing effects. So what is the principle of uv printers?

 

1. Printing principle:

 

The uv printer relies on the voltage inside the nozzle to eject the ink in the nozzle hole to the surface of the substrate to achieve the purpose of printing pictures. Generally, there are thousands of nozzle holes on a small nozzle, and the nozzle can control the ink output of the nozzle holes.

 

2. Curing principle:

 

The uv printer uses the ultraviolet waves emitted by the uv lamp to react with the photosensitive curing agent in the UV ink, causing the pigment molecules in the UV ink to solidify on the surface of the material to achieve rapid drying of the ink, so traditional baking and drying procedures are not required.

 

3. Positioning principle:

 

The uv printer can accurately control the printing patterns on different materials and shapes mainly rely on the positioning principle: on the X-axis positioning, it mainly relies on the grating decoder to direct the horizontal printing of the equipment; on the Y-axis, it mainly relies on the servo The motor is driven to control the length of the printing material; on the Z axis, it mainly depends on the lifting function of the machine head.

 

How does uv printing work?

 

The uv printer has brought us a colorful life, like the posters on the street, the patterns on the cups, the contents of our books, etc. are inseparable from the printer, it replaces the advantages of manual labor that cannot work quickly and effectively, Improved work efficiency.
