Waterless offset printing technology is maturing, but the number of printing companies that try and apply waterless offset printing technology is not large. The reason, cost and technical maturity are still “landing†obstacles. Cost proposition
A practitioner in the plate industry told reporters that waterless offset printing requires the use of special plates and inks, while the price of waterless offset plates is about 20% higher than that of ordinary offset plates. Waterless offset inks are more than ordinary offset printing. The price of ink is also about 10% higher. At a time when the operating profits of printing companies have generally declined, many printing companies have come up with high funds to purchase water-free offset printing supplies.
Of course, the printing production process is a whole, and the single cost of consumables is obviously not comprehensive. The comprehensive cost of waterless offset printing and water offset printing is more rational. One interviewee gave his company a comprehensive application cost accounting for waterless offset printing technology, with 21 days of work per month, 8 hours of work per day, 1,000 printing plates, and 1 million prints produced: in normal printing Under the entire production process, waterless offset printing has water offset printing, which can save the cost of developing solution and other pharmaceuticals, waste disposal cost, and machine maintenance cost (mainly refers to water roller and water roller related equipment maintenance costs). Thousands of yuan, the replacement time and preparation time of each printed job is reduced by 20% to 50%, the effective working time is increased by 16%, the printing loss of each device is reduced by 30%, and the paper is saved 150kg per month. However, he also said that this does not completely offset the increase in costs associated with rising cost of waterless offset supplies.
Technical considerations
In addition to cost considerations, technology maturity is also a challenge to promote waterless offset printing technology. A printing company with a leading position in the industry in Shenzhen has used waterless offset printing technology for many years, but it still faces many problems in the application process. For example, because the water-repellent offset plate is partially made of silicone, it is extremely easy. Scratched, therefore, the waterless offset printing plate has a higher bad rate. During the same test, the waterless offset printing rate is reduced by about 35% compared with the water offset printing in the same time; due to the high viscosity of the waterless offset printing ink The existence of printing pressure, the printing registration is still difficult, especially the long paper registration is more difficult. In addition, a representative of a printing company in Beijing that uses waterless offset printing technology to produce safe printing products also told reporters: "Operator's mastery of waterless offset printing technology is also the reason for limiting the wide application of waterless offset printing technology. Although waterless offset printing has Water offset printing is easier to operate, but if the operator does not understand the waterless offset printing technology and is not familiar with the difference between waterless offset printing and water offset printing, it will lead to frequent failures." For example, the operator must pay attention to the amount of waterless offset printing ink. Less than water offset printing, otherwise easy to stick blanket, resulting in paste phenomenon; must be dedicated to the waterless offset printing curve; printing plate cylinder and blanket cylinder should be very flat, otherwise it will easily damage the printing plate.
In general, waterless offset printing is receiving much attention, and technology is becoming more mature, but it will take time to fully promote it. On the one hand, suppliers should further improve the level of waterless offset printing technology, develop low-viscosity, high-flow waterless offset printing inks, improve the abrasion resistance and dirt resistance of waterless offset printing plates, and further reduce the waterless offset printing consumables. Costs, to eliminate printing companies' concerns about cost and technology; on the other hand, printing companies should also make more efforts in training operators and their own technology.
