Using digital inkjet printing, its process is simple, no need to make screens and proofing, high degree of automation, colorful colors, high resolution, no environmental pollution, is a true ecological high-tech printing process, it will develop rapidly in the future, and it is urgent to develop general Paint ink with strong performance, low cost and no need for pre-treatment.
Adopting transfer printing: Disperse dye sublimation transfer printing is currently widely used, and some ionic dyes such as new thermal diffusion transfer printing and reactive dyes are being researched and developed (but water washing and sewage discharge are required after printing.) If paint is used Transfer printing does not require baking and washing after printing, and no sewage is discharged, but it has higher requirements for coatings and adhesives. Thermal diffusion transfer printing is currently one of the most promising imaging technologies.
