Many years ago, precisely in 1994-1995, many people believed that the emergence of digital printing was a threat, especially for screen printing, it was a terrible threat. Within five years, digital printing will annex screen printing, and even Americans and Europeans believe this. Fortunately, in the face of this situation, there are other down-to-earth and visionary people, such as the highest screen printing professional organizations such as the European Screen Printing Association (FESPA) and the International Screen Printing Association (SGIA). The best solution is to organize and integrate large-format digital printing within their associations, and then combine digital printing in their own printing plants, so that digital printing will not occur in front of the screen printing. competition. I remember that in some international technical lectures and exchanges, including the FESPA exhibition in Lyon in 1996, some digital printing practitioners have done statistics. They claim that the results of statistics show that digital printing is in other printing processes (mainly It ’s screen printing) There will be breakthrough expansion in front of the position, but they have forgotten the following three points:
1. Due to mechanical and physical limitations such as the conversion speed of the printing head or the ejection speed of ink droplets, digital printing technology will eventually reach its limit at some time or soon;
2. They often claim that digital printing can achieve a high printing speed, but forget that its actual printing resolution is only 50dpi or 72dpi. Suppose you want to achieve the quality required for printing POP, that is, 300dpi or 600dpi, the printing speed should be reduced by 6 to 12 times, the speed of 600m2 / h becomes 100m2 / h or even 50m2 / h. In screen printing, the quality required by our customers is 300L / inch (120L / cm), often 610dpi, and we need photo-like quality. In contrast, the speed of digital printing is too slow;
3. Many digital printing processes require that the printing materials used must be pre-processed, and after the printing is completed, special finishing processes must be carried out in order to provide mechanical and physical protection for the printed matter. These finishing processes use The inks or colorants are very expensive, and the finishing process will increase the cost of printed products. In addition, they also neglected how the screen printing process can react so quickly in the following aspects.
1). Screen printing, like offset printing and other printing processes, makes full use of the advantages of digitization, and its pre-press process quickly realizes all digitization.
2). Screen printing technology has developed a large-format multi-color printing machine for graphic printing and a computer-made screen printing plate system, and has comprehensively improved and improved screen printing technology, products, equipment and productivity. As a result, in 1996, digital printing of 100 copies of jobs was cheaper, and by 1990, the more economical number of digital printing fell to 50 copies, and screen printing quickly regained a lot. Part of the lost market. The actual situation is not as optimistic as they predicted. Screen printing has reached relative stability in Europe and other parts of the world. For many screen printers, digital printing has become their necessary and complementary business. Digital printing has been accepted by screen printers. Its existence is no longer regarded as a threat, but a very meaningful opportunity. This is why our screen printing companies must enter the field of digital printing. Let us now discuss the digital printing market. For the digital printing market, my opinion is that some medium-sized screen printing companies or sign manufacturers have about 20 to 40 employees, equipped with some semi-automatic and fully automatic screen printing production lines, suitable for their choice of digital The printing technology should be a piezoelectric inkjet printer, not a thermal inkjet. Thermal inkjet machine is too limited, it can only print on some traditional printing materials. However, 50% of piezoelectric inkjet printers use solvent ink, which has environmental pollution problems.
I once suggested to a friend in Italy that it is best to purchase a platform piezoelectric inkjet machine that uses advanced UV technology. This system can print on a variety of printing materials without special processing before and after printing.
This is a major advancement in digital printing technology, which perfectly adapts to the needs of screen printers, enabling them to provide more services to customers without any environmental pollution problems. For a small-scale screen printing plant with an investment of 150,000 US dollars, the production operation should be free of any pollution, no additional drying device, and only a UV curing system after the print head. You must know that operating in an ultra-large format (more than 4-7m wide) market means that your investment must reach at least 700,000 US dollars. For some large companies with investment potential, this number is still very conservative. In this case, you need to do many commercial operations. Need to print 30m2 or wider prints, for most customers only once a year, only your production business for one year, your sales staff will provide you with 200 to 300 new customers. On the contrary, if your digital technology investment is reduced to a minimum, below 20,000 US dollars, in this case, you can only print jobs with a width of less than 135cm, the printing speed is not fast, the quality level is in the middle and lower, but, This helps you serve your existing or new customers. Such digital printers can only use solvent inks (unfortunately the volatiles are above 50%), and behind the digital printers use screen printing traditional infrared dryers (IR) or air jet dryers. Of course, there is a problem of environmental pollution.
