Analysis of the Disadvantages of Digital Printing

Digital printing technology still needs to be improved, and its shortcomings are mainly manifested in four aspects:
（1） The printing speed is slow.
Efficiency is money, and the speed of printing largely affects the efficiency of the enterprise. At present, the fastest digital inkjet printing machine can achieve a printing speed of 150m2/h, but compared to traditional printing machines, it is still far behind and needs further improvement.
（2） Ink costs are relatively high.
Although digital inkjet printing does not require the production of screen printing, the total cost of small-scale production is lower than that of traditional printing. The price of the ink used is much higher than that of the dyes and pigments used in traditional printing. Therefore, beyond a certain printing length, the ink price will drive the cost of digital inkjet printing to exceed that of traditional printing. Reasonable adjustments need to be made to the price of future ink in order to promote the development of digital inkjet printing.
（3） The integration of new and old technologies.
Digital printing technology is constantly improving, and the printing speed is also accelerating. However, there is still a long way to go to catch up with the speed of traditional printing machines. Therefore, the basic composite pattern of textile printing industry in the future will be to use time-saving digital printing machines for proofing or small-scale production, and then use traditional printing machines for mass production. The combination of new and old technologies still faces challenges and further breakthroughs are needed. [1]
（4） Color accuracy
Compared to traditional spot color printing, where each set of colors is individually matched with a color paste, a computer based color measurement and matching system can achieve high color accuracy. Even if a certain color paste deviates, it only affects one set of colors. Digital printing is a CMYK mixed color printing, where all colors are mixed with four color ink. Any slight external influences such as ink differences, differences between print heads, and minor changes in the printing process can affect the accuracy of a series of colors after mixing. Therefore, the color accuracy of digital printing is slightly worse than that of traditional printing.
