The difference between UV inkjet printer and small character inkjet printer

by:Leadtech Coding     2021-12-08

UV inkjet printers and small character inkjet printers are all ink inkjet printers, but their working principle, application industry, printing height and market price There are differences. When purchasing an inkjet printer, you only need to understand these four points to quickly make a choice that suits you.

1. The working principle is different.

The small character inkjet printer adopts continuous inkjet technology (Continuous ), The ink dots are deflected out of the normal flight path by means of electrified deflection of the ink, and projected to the surface of the target printed matter to form a dot matrix, thereby forming characters, numbers or graphics.

UV inkjet printer is a high-resolution inkjet printer (a new type of inkjet equipment), using drop on demand inkjet technology (Drop On Demand) piezoelectric inkjet coding The ink is not recycled, the ink density is consistent, no thinner (solvent) is added, and the operating cost is lower than that of the small-character cij printer.

2. Different application industries

Small character inkjet printers are used in food, beverage, pipe, medical packaging, wine There are many applications of coding on products such as, cables, daily cosmetics, electronic components, PCB circuit boards, etc. The content suitable for printing is mainly production date, expiration date, shelf life, LOGO pattern, counter, time information, etc., printing traceability The resolution of the QR code is not high.

Because of its ink characteristics, UV cij printers are favored by manufacturers in various application industries. UV inkjet printers can be dried and cured immediately after being irradiated by ultraviolet curing lamps, which is stable Good performance, can realize inkjet marking on various materials, and can print various variable data online in real time, including barcode, two-dimensional code, date and time, counter, LOGO, graphics, tables, databases, etc., widely used in food , Pharmaceuticals, daily chemicals, label printing, card making, packaging and printing, medical, electronics, hardware and other industries.

3, the printing height is different

The printing height of the small character inkjet printer is generally between 1mm-15mm Many cij printer manufacturers will advertise that their equipment can print 20mm or 18mm height. In fact, few manufacturers can do it. Usually small character inkjet printers can only print 5 lines at most, and the best printing distance is within 1cm. The effect is that 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 the product label.

The printing height of UV cij printers is much higher than that of small character cij printers. For example, UV inkjet printers can reach 54mm without splicing. The splicing extension of the sprinkler head can currently reach up to 129.6mm, which can realize high-definition large-scale coding, and the recognition rate of the printed two-dimensional code is as high as 99%, which is especially suitable for products that require 'anti-counterfeiting traceability, one item, one code'.

4. The market price is different

Compared with UV inkjet printer, the price of small character inkjet printer is cheaper , The price of a UV cij printer is 3-4 times the price of a small character inkjet printer. The inks used by the two are different. UV ink is an ink that needs ultraviolet radiation to dry. The ink density is consistent and does not need to add a thinner (solvent); the small character ink is a normal ink and needs to be added. Even if it is not turned on, the ink volatilization will be reduced.


Clouds of expiry date printing machine failures surround the world of date coding machine in particular, simply because people don’t pay as much attention to the cij printer as they should do.
Leadtech Coding has a whole range of different items to help you make an informed choice every time you make a purchase. Check it!
These date printing machine cij printer are not only useful but also more cost effective than those traditional ones.
