【Abstract】 The paper introduces a new treatment method before printing that is helpful for those plastics, which are hard to be printed. This subject was finished by means of many systems experiments according to polymer physics and plasma physics combining print principle.The critical surface tension,coarse degree and the oil ink adhesive force of plastics were improved, so the print adaptability was improved. This method have not those shortcoming of traditional chemical methods such as low efficiency, drainage of waste liquid, and pollution of environment. It gave the possibility to increase plastics applied extents especially to those plastics products which were not regular. The feasibility and reliability of plasma treatment were confirmed after finishing the comparative tests of plasma treatment, the determination of critical surface tension, the tests of oil ink adhesive force and observation results of surface coarse degree of plastics using polarizing microscope.更多还原
