he basic principle of inkjet printing is to first generate small ink droplets and then guide them to a set position, which can be roughly divided into two types: continuous jet and drop on demand.

• Continuous inkjet printing (CJI)

(1) Deflected Drop to Print
(2) Undeflected Drop to Print
Both prints and non-prints produce ink droplets in a continuous manner, while non-printed ink droplets are recovered. This method is generally used for printing labels or cartons and lower-order products.

• Controlled Drop Inkjet Printing (DOD)

(1) Piezo (Piezo)
(2) Thermal bubble
Both produce ink drops in the printed area. Piezoelectric inkjet is characterized by being electrically deformed by a material, and is pressed against the ink to cause the ink droplet to be ejected through the nozzle and landed at a predetermined position. The main supplier is Epson et al. The thermal bubble type inkjet uses the sheet resistance at the end of the nozzle to instantaneously heat up to a high temperature, so that the ink forms bubbles by boiling, and the ink droplets are pushed out along with the bubbles, and the ink droplets are sprayed to a predetermined position of the substrate through the nozzle. Major manufacturers include Canon, HP, and Lexmark.

The type of ink can be divided into three types: oil-soluble type, water-soluble type and hot-melt type. The inkjet printer ink used in general office is mainly water-soluble ink, which is mainly composed of dye and has a wide color gamut. High brightness and chroma and high reproducibility and non-toxicity.

The inkjet inks produced by our company are strictly controlled by precision instruments in the manufacturing process and quality control. It is suitable for Epson and HP two types of printer systems, not only the printing process is smooth, but also the nozzles are not cleaned. Nozzle), the ink loss is small (cost saving), and the nozzle is not corroded (expanding the life of the nozzle), the printing color is bright and bright, and the anti-light effect is higher than the general commercial ink.
