UV printer is a new type of direct digital printing technology developed in the past ten years, which is directly printed on the surface of the product by computer control using software, also known as non-contact inkjet printer. UV printing has achieved a breakthrough in digital printing to the industrial field. Before we mentioned that UV printing is one of the processes of trademark printing. Today we will specifically understand how UV printing operates.
UV printing basic knowledge:
What is UV printing?
UV printing is a process that uses an ultraviolet light source to cure coated ink so that it dries quickly and forms a hard coating. The UV in the UV printer is the abbreviation of ultraviolet light, that is, the ultraviolet light emitted by the LED lamp is used, so that the printed product is dry in the printing process, that is, the pattern will not be blurred.
Classification of UV printing?
According to the type of UV printer classification: can be divided into coil printers, flat printers and cylindrical printers.
Classification according to the UV printing mode of operation: can be divided into positive and reverse.
According to the principle of UV printing imaging classification: can be single color, color white, color white, color white and black color.
UV printing process:
Step1: design the manuscript, the manuscript needs to be tif.jpg/eps/pdf image file format;
Step2: edit the pattern information on the computer, and output it to the inkjet machine;
Step3: to be printed material dust treatment, need to wipe with alcohol;
Step4: digital printing equipment directly printing production (early CNC production of furniture can be);
Step5: Irradiation of UV light (ultraviolet) while printing, so that the ink can be cured instantly.
Advantages and effects of UV digital printing
1. Multi-material application: UV digital printing is widely used in printing of various materials, without replacing different types of equipment.
2. Strong adhesion and scratch resistance: the ink used in UV digital printing is cured by UV, making the print have high adhesion and scratch resistance, not easy to fade, and even can withstand the harsh outdoor environment.
3. Good printing effect: the printed matter printed with UV ink is bright in color and has the advantages of high printing consistency. Can achieve high-precision printing, you can print out a delicate, realistic image.
4. High speed and high efficiency: UV ink digital printing can reach a printing speed of more than 100 square meters per hour, greatly shortening the printing cycle and improving production efficiency. In addition, because the UV curing process is a photochemical reaction process, the curing time is very short.
5.Dry immediately: Use LED or UV-cured inks, they can dry immediately.
The way UV printing products are detected
There are many standards to judge the print quality, in addition to the test of firmness, there are some related quality tests, such as anti-aging test, anti-low temperature performance, anti-ultraviolet (fast sun) performance and soon. Among them, the more intuitive and important way is the test of firmness — the hundred-grid experiment.
Hundred grid test is the national standard test method for detecting the adhesion of coating or coating, which is to draw equal squares on the coating or coating, and then pull with special tape, and judge the adhesion according to the shedding of the coating (plating) layer.
Usually select a 10*10mm test surface on the spray surface and cut it into 1*1 small pieces, and then paste the area with a special tape and wipe it with a rubber to ensure close adhesion, and then tear it off quickly at 90。departure Angle to test whether the falling off area meets customer requirements.
