Inkjet printer
The inkjet printer is a product of a large-scale printer series. There is no high definition of printing and photocopying machines, but the inkjet printers that are now launched have a great improvement in definition. It uses solvent-based or UV-curable inks. The solvent-based inks have strong odor and corrosiveness. During the printing process, the ink penetrates into the interior of the printing material through corrosion, making the image less likely to fade, so it is waterproof and UV-resistant. , scratch resistance and other characteristics.
Inkjet printer classification
Inkjet printers can be divided into two types according to the format: large format inkjet printers and ultra large format inkjet printers.
The large-format inkjet printer has a width of about one meter, and is printed by dye ink. The resolution is higher (up to 600-1000 DPI), and it can be sprayed to high-gloss photo paper to produce a photo effect. However, due to the limitation of ink performance, the product is not waterproof or UV-resistant, and must be coated or coated later, suitable for renderings and samples.
The ultra-large format inkjet printer has a width of more than 3 meters. It uses pigmented ink to print, mainly facing the outdoor huge advertising market, and the resolution can meet outdoor requirements (usually 24-70 DPI can fully meet outdoor demand).
Inkjet printers can be divided into airbrush type and piezoelectric type according to the principle of inkjet printing.
The airbrush type inkjet printer is the earliest form of large format inkjet printer. This type of inkjet printer has been launched relatively early, the technology is relatively mature, and the machine failure rate is relatively low. In the production of super large format works, the color of the equipment is too soft and uniform. However, the text and lines are ambiguous, and at the same time, due to ink limitation, coating or filming is required later, and splicing often causes chromatic aberration. At present, due to technical limitations, the accuracy and speed of this kind of equipment have not been significantly improved, so its market competitiveness is gradually weakening, and the more advanced piezoelectric inkjet printers are gradually becoming the mainstream of the market.
Piezoelectric type is divided into piezoelectric continuous inkjet (CIJ) and piezoelectric drop-on-demand (DOD). Piezoelectric continuous inkjet is a CIJ continuous inkjet technology that has matured in industrial automation production lines.
Inkjet printer application industry
1. Glass industry
The digital inkjet printer can directly print various patterns on the glass surface instead of hand-painting, realizing the instant processing without plate, high efficiency, low cost and rich color.
2, decoration and decoration industry
UV digital inkjet printer can directly print the required patterns on the surface of various decorative materials such as ceiling, fireproof board, aluminum-plastic board, MDF, stone, ceramics, glass, etc., to meet the needs of individual decoration, and bring considerable economy to the architectural decoration company. benefit.
3. Signage industry
The digital inkjet printer can directly print patterns on the surface of various hard sign materials, replacing traditional signage processes such as screen printing, etching, and filming, which reduces the number of processes, reduces costs, and increases the degree of firmness.
4, murals, decorative painting industry
The digital inkjet printer can directly print patterns on the surface of ceramics and wood products instead of manual painting and screen printing. The products are post-treated, wear-resistant, water-resistant, temperature-resistant, and radiation-resistant indicators meet the requirements, and meet the needs of personalized decoration.
5, exhibition board production
The platform digital inkjet printer can directly print the required patterns on the surface of various advertising plates such as KT board, Chevron board and plexiglass, instead of photo printing and laminating process, without degumming, non-foaming, low cost and time saving.
