Ice flower UV ink intermittent curing method

① ice flower ink is not only suitable for mechanical printing, but also suitable for manual printing. In order to obtain good printing effect, in production practice, appropriate printing conditions, such as pressure, scraper angle and distance, should be adjusted according to their own actual conditions, such as insufficient base strength or too high surface humidity. It is recommended that the shore hardness of the scraper be 65~75

② it is not suitable to use the process of overlaying ice ink on the color ink layer. If this process is applied to the printing of ice flower ink, it will affect the final pattern effect and firmness of ice flower ink. The reason is that different colors of ink have different absorption of ultraviolet light. It is recommended to use colored ice flower inks

③ ice flower ink shall be fully stirred before printing to make it even. In particular, when the ice flower ink with several patterns is mixed, it should be stirred with bamboo board. It is best to use a wide leaf mixer for mixing in large quantities, and the inclined angle of the middle leaf of the mixer is 30~45

④ curing and drying shall be carried out immediately after printing. The ice flower UV ink adopts intermittent curing method, and the transfer speed of the printing on the curing machine is 25~35m/min. Curing light source 3 The servo valve is regularly replaced with 6 UV lamps discharged in parallel. Therefore, the power intensity is 60~80w/cm. 5. Limit protection of lamps: it has the function of mechanical and program-controlled limit protection; The interval is 60~80cm. The light intensity of the first three UV tubes is controlled to be (3 ~ 4) w/cm2, and the light intensity of the last three UV tubes is controlled to be (4.5~5.5) w/cm2. During curing, after the printed matter passes through the first three UV lamps, it should be blown by wind in the cooling area, then enter the curing area of the last three lamps, and then blow by cold air
