Both UV inkjet printers and small character inkjet printers are inkjet printers, but there are differences in their working principles, application industries, printing heights and market prices. When purchasing an inkjet printer, you only need to understand these four points , you can quickly make a choice that suits you.
1. Different working principles
The small character inkjet printer adopts the continuous inkjet technology (Continuous Inkjet Printer), which uses the charged deflection method of the ink to deflect the ink dots out of the normal flight path, and shoots to the surface of the target printing object to form a dot matrix, thereby forming characters , numbers or graphics.
The UV inkjet printer is a high-resolution inkjet printer (a new type of inkjet equipment). It is a piezoelectric inkjet printer using Drop On Demand technology. The ink is not recycled and the ink concentration is consistent. Add thinner (solvent), and the running cost is lower than small character inkjet printer.
2. Different application industries
Small character inkjet printers are widely used in food, beverages, pipes, pharmaceutical packaging, alcohol, cables, daily cosmetics, electronic components, PCB circuit boards and other products. The content suitable for printing is mainly the production date , validity period, shelf life, LOGO pattern, counter, time information, etc., the resolution of the printed traceability QR code is not high.
Due to its ink characteristics, UV inkjet printers are favored by manufacturers in various application industries. UV inkjet printer inks can be dried and cured immediately after being irradiated by ultraviolet curing lamps. They have good stability and can realize inkjet marking on various materials. It can print various variable data online in real time, including barcode, two-dimensional code, date and time, counter, LOGO, graphics, form, database, etc. It is widely used in food, medicine, daily chemical, label printing, card making, packaging Printing, medical, electronics, hardware and other industries.
3. Different printing heights
The printing height of small character inkjet printers is generally between 1mm-15mm. Many inkjet printer manufacturers will advertise that their equipment can print 20mm or 18mm in height. In fact, few manufacturers can do it. Usually, small character inkjet printers are the most Only 5 lines can be printed, and the printing distance is within 1cm for the best effect. If the distance is too large, the printing effect will be greatly reduced, and the dot matrix may also be irregular, which will affect the quality of product marking.
The printing height of the UV inkjet printer is much higher than that of the small character inkjet printer. For example, the micro-embedded UV inkjet printer can reach 54mm without splicing. For example, the splicing and expansion of multiple nozzles can reach up to 129.6mm at present, which can realize High-definition and large-scale printing, and the recognition rate of the printed QR code is as high as 99%, which is especially suitable for products that require “anti-counterfeiting and traceability, one code per item”.
4. Different market prices
Compared with UV inkjet printers, the price of small character inkjet printers is cheaper, and the price of a UV inkjet printer is 3-4 times the price of a small character inkjet printer. The inks used by the two are also different. UV ink is an ink that needs to be irradiated with ultraviolet rays to dry. Even if it is not turned on, the ink will evaporate less.
