Waterless offset printing technology is mature, but try and apply the waterless offset printing technology printing enterprise quantity is not much, investigate its reason, cost and technical maturity is still ground obstacles.
1, the cost of proposition
Said a plate industry, supporting the use of the special edition of waterless offset printing needs of material and ink, and waterless offset printing plate price is about 20% higher than ordinary offset printing plate prices, waterless offset printing ink than ordinary offset printing ink, the price also is higher than 10%.In printing enterprise operation profit declines in the present, let many printing companies suddenly put up high money to buy waterless offset printing consumables is really too much for some.
Printing production process as a whole, of course, a single look only at the material costs are clearly not comprehensive, comparison of waterless offset printing and offset printing water comprehensive cost more rational.Integrated application of cost accounting of waterless offset printing technology, for 21 days, 8 hours a day working hours per month, out of 1000 plate, producing 1 million pieces of print meter: under the condition of normal printing, from the whole production process, compared with the waterless offset printing offset printing water, a month can save drug expenses such as developer, liquid waste processing costs, machine maintenance costs (mainly refers to water roller and water roller) related equipment maintenance costs thousands of dollars, changing time and prepare for every single templates time reduced by 20% ~ 50%, the effective working time increased by 16%, each device of the printing loss amount decreased by 30%, save paper 150 kg per month.But this does not completely offset waterless offset printing consumables cost rising cost increase.
2, technical considerations
Except for the cost consideration, technical maturity is also a difficult problem in promotion waterless offset printing technology.A shenzhen technology level in the industry in a leading position of the printing enterprise, although has the waterless offset printing technology for many years, but it still faces many problems in the process of application, such as: because the waterless offset printing plate investing ink part for silica gel layer, easy to be scratched, therefore, waterless offset printing edition version of bad rate is higher, in the process of a test, the same time, waterless offset printing offset printing with water is reduced about 35%;Because of the large waterless offset printing ink viscosity and printing pressure, its printing alignment is still difficult, especially long grain paper alignment is difficult.In addition, a Beijing the waterless offset printing technology in the production of security printing products printing enterprise representatives also said: "the operator on the degree of master waterless offset printing technology is also the cause of limiting waterless offset printing technology is widely used. Although there are water than waterless offset printing offset printing easier to use, but if the operators do not understand waterless offset printing technology, is not known to have water waterless offset printing and offset printing differences, will lead to failure occurred frequently."For example, the operator must pay attention to the dosage of waterless offset printing ink to less than water offset printing, otherwise easily lead to paste version phenomenon; sticky rubber cloth,Must for waterless offset printing production special publishing curve;Printing equipment of the plate cylinder and rubber roller should be very smooth, otherwise easy to damage the plate, etc.
Overall, waterless offset printing is concern, technology is maturing, but to the comprehensive promotion still will take time.On the one hand, suppliers should also further improve the level of waterless offset printing technology, research and development of low viscosity, high liquidity waterless offset printing ink, improve the abrasion resistance of waterless offset printing plate, dirty resistance, etc., and further reduce the waterless offset printing consumables cost, dispel printing enterprise concern about cost and technology;On the other hand printing enterprise should also be in training to operators and their own technology to make more efforts to accumulate.
