Classification of UV printer nozzle

                  The classification of UV printer nozzles is introduced. When customers buy UV printers, manufacturers will introduce the nozzles of UV printers. There are currently two types of nozzles used in UV printers on the market.

Classification of UV printer nozzle.

                 Comparison of Seiko industrial sprinklers and EPSON sprinklers:

                1, Epson has a nozzle with 180 holes in 8 rows, with a total of 1,440 holes. One nozzle can print 8 colors, while Seiko nozzle has one nozzle, one color, and four colors and four nozzles. The number of holes is 1024.

               2, Epson's ink drop is 3.5pl, and Seiko's minimum is also 12pl. In contrast, Epson's accuracy is much higher and much more delicate.

               3, Epson print head can choose four-color, six-color, eight-color, double-four-color printing, and Seiko print head requires one print head per color, which costs more.

               Epson print heads have the advantages of high precision, high speed, and low price before they have become the darlings of the market. Hangzhou Kale also developed Epson's five-generation print heads independently developed UV printers.

              When it comes to UV printers, I have to talk about UV lamps. It is an important part of the UV printer and the key to the printing process.

              UV lamps are also divided into two categories, one is the traditional ultraviolet mercury lamp. It has the advantages of high power and fast drying, but its heat generation is large. Poor mercury lamps can even deform the material during the printing process. There is also a current class of more advanced LED lamps. The advantages are low heat generation and energy consumption. Low and long life. With the development of LED uv lamps, the drying efficiency of today's LED uv lamps is close to catching up with mercury lamps. At the same time, LED lamps are also more environmentally friendly and non-toxic than mercury lamps. LED lamps are now the preferred component of uv printer manufacturers.

              Screen adhesion:

              Although UV ink can be printed on any surface, the adhesion of various materials is different. Boards such as wood boards and chevron boards have better adhesion, and they are not easy to fall off after the image is sprayed on. However, the denser materials such as glass and metal plates have a weaker adhesion after painting.

              To increase the adhesion of the printed image, you can increase the adhesion through pre-processing and post-processing. For example, spray a professional coating on the surface of the material before spraying, and the image adhesion after spraying will be much higher. You can also spray a layer of varnish or varnish on the surface of the material after spraying to isolate the outside from direct contact with the image. There are also some other processes, such as double-sided glass, which seals the image in the middle of the glass to achieve the purpose of never peeling the image.
