Digital printing has four advantages over traditional proofing.
With its fast proofing, digital printing machine can enhance the response speed of the enterprise to the order, step by step in the shopping mall, enhance the competition of printing enterprises, reduce the processing price and reduce the profit space. Customers put forward higher requirements for printing enterprises from aspects of cost, response speed, quality, service and so on. Improving the speed of proofing will undoubtedly make the enterprise win in the hands of many competitions.
The use of digital printing machine can replace some of the original work that must be done on the circular and flat screen printing machines without taking up the time of the machine. Usually a sample often takes up 3-4 hours of a machine. If the customer is not satisfied, it will be modified again and again, resulting in a great waste of production capacity.
3、The effect is good and the customer's approval rate is high
Digital printing and traditional printing belong to different systems. Many professional and technical personnel are worried that the effect of proofing with digital printing machine is too good. Traditional printing can not achieve this effect. In fact, this worry is unnecessary. At present, in order to solve this problem, domestic companies have organized the best technicians in China to carry out in-depth research and find out the solutions. This scheme uses software to adjust the effect of digital printing, so that the traditional printing machine can fully achieve the effect in production. From the perspective of color, because the color range of traditional printing paste is wider than that of digital printing ink, the color effect produced by digital printing machine can also be simulated by traditional sizing agent.
4、Wide range of application
The ink that can be used for proofing has active ink, acid ink, dispersed ink (transfer printing), and the use of dispersed ink is used to find the right ink. In the customer's sample, if it's paper manuscript or electronic manuscript, it can be directly printed with digital printing machine after color separation. The traditional printing machine can complete mass production according to the proofing effect.
If the sample is the sample, you need to explain to customers some of the characteristics of digital printing, in recognition of clients before the change proofing mode. In particular, enterprises should take into account the ability of customers to accept new things. For some conservative customers, it is still safe to use traditional proofing methods. Only when digital proofing becomes the mainstream of the market, it is appropriate to recommend digital print proofing to these customers. This process will take about 2-3 years at home.
Digital printing technology and traditional printing technology are two completely different printing mechanisms. Therefore, the use of digital printing machine proofing needs to have a running in period with customers. From the point of view of the process, there should be a running in period in the enterprise's internal proofing and production system. If it is possible to establish a set of technical standards, the enterprise can quickly import digital printing system for customers.
Digital printing technology needs to be improved, the disadvantages of digital printing technology, mainly in four aspects:
(1) the speed of printing is slow.
Efficiency is money, the speed of printing is to a large extent the benefit of the enterprise. At present, the speed of the fastest digital ink jet printing machine can reach 150m2/h, but it is still far behind the traditional printing machine, and it needs to be further improved.
(2) the ink cost is high.
Although digital ink-jet printing without making screen, a small amount of production total cost than traditional printing, dye and pigment ink which is cheaper than traditional printing is much higher, so more than a certain length after printing, digital printing ink prices will boost the cost of making more than traditional printing. The price of the ink in the future needs to be adjusted reasonably to promote the development of digital ink-jet printing.
(3) the problem of the combination of new and old technology.
Digital printing technology continues to improve, the speed of printing is also accelerating, but to catch up with the speed of the traditional printing machine still has a long way to go. Therefore, the use of time-saving digital printing machine for proofing or small quantity production, combined with traditional printing machine for mass production, will be a basic combination mode of textile printing industry for a period of time. And the combination of new and old technology and difficult problems, we need to make further breakthroughs.
Compared with the traditional printing of spot color printing, namely, each set of colors individually adjust the color paste, through the computer color matching system, we can achieve high color accuracy, even if a color paste deviate, it only affects one color. The digital printing is CMYK mixed color printing, all colors are mixed by four color ink. A little bit of external influence, such as ink difference, printhead difference and tiny change in printing process, will affect the accuracy of a series of colors after blending. Therefore, the color accuracy of digital printing is a little worse than that of traditional printing.
