Spot accuracy is a reflection of the high-precision calibration error of inkjet points and an important parameter for uating the control accuracy of inkjet printing systems。

By calculation, optimize and control the peak value and micro droplet accuracy of the edge after inkjet dot forming。

When inkjet droplets spread on the substrate, surface defects and other reasons can cause solutes to "nail" at the contact line, and the droplets will continue to maintain this spreading shape. Due to the fast solvent evaporation rate at the contact line, the solution will transfer and compensate for the evaporated solvent from the middle of the droplet to the edge of the droplet. Finally, solutes deposit on the substrate to form an uneven thin film with thick edges and thin middle layers, known as the "coffee ring" effect. The uniform diffusion accuracy of micro and nano particles is controlled through thickness compensation technology。

This is a super inkjet technology jointly developed by the Inkjet Research Institute and the Nanometer Research Institute. Compared with the droplet size that inkjet printheads used in inkjet printers on the market can spit out, the size of ultra-fine droplets can reach about 1/10 or less (with a volume of less than 1/1000). In addition, the corresponding viscosity range is 0.5-10000/mPa. s, achieving high-precision non heated discharge that traditional inkjet technology cannot achieve. Therefore, we have achieved remarkable results in the discharge of a wide range of liquid materials, including nanoinks such as Ag and Au, insulating inks, various corrosion inhibitors, adhesives, proteins, etc.

Disrupting the existing inkjet concept and achieving high viscosity non heated discharge of 10000/mPa. s。

Due to the high dryness of ultrafine droplets, the droplets spit out in a liquid state will quickly dry and evaporate. Therefore, by placing them in the same position, a three-dimensional stacking structure can be formed, which is common in the field of biology。
