At present, there are mainly two types of inkjet printing technologies: continuous inkjet printing and pulse printing technology. The former can be designed as a double or multiple bending system, the latter can be divided into thermal inkjet, piezoelectric inkjet, valve inkjet, electrostatic inkjet process. The following outlines the development direction of inkjet printing technology.
Various printing technologies are evolving at ever-changing speeds. In recent years, people are working to apply digital printing technology, which is mainly applied to paper, to the printing of textiles. However, due to the significant differences in the nature of textiles and paper, many new problems have arisen in practical applications. First of all, the amount of textile image required for printing a unit area is much higher than the corresponding amount of ink printed on the paper, which inevitably brings problems related to printing speed, firing frequency of the ink droplets, and service life of the nozzle. Second, chromatographic requirements in textile printing are much wider than paper printing. In order to obtain a high-quality printed image, high-resolution dot-matrix and multi-level color gradation are required. In paper-based inkjet printing systems, the quality of printed images is often improved by increasing the resolution. In traditional printing technologies, such as screen textile printing, this goal is achieved through high grayscale (resolution is now relatively high. Low, this difference will in turn bring new image quality control issues to inkjet textile printing.
Another important development direction of printing technology is the digital control of the printing process and the personalized processing of printed products. To achieve this goal requires good computer design software, good performance printers and ink coordination. This has been achieved in small products such as ties, flags, etc. due to personalized prints of patterns and colors in inkjet printing.
In addition, recently there have been some new areas of application of inkjet printing technology such as medical images, 3D printing products, digital printing newspapers, and publications. It can be seen that ink-jet printing technology will have a broader development prospect in the future.
