Abstract

The invention belongs to the technical field of printing, and in particular relates to a printing process for finishing a UV (ultraviolet) snowflake pattern by offset printing. The technical scheme of the printing process is characterized by comprising the following steps: (1) designing and typesetting according to the printed characters, patterns and signs to generate to a CTP (computer-to-plate) with 150 to 200 lines per inch; (2) arranging the CTP generated in the step (1) to the last group of printing units of a UV offset printing machine, and placing printing paper into a Fidek; (3) adjusting the viscosity of UV offset printing snowflake printing ink to be 20 to 30 S, and adjusting an inking position of the UV offset printing machine to be 20 to 70 percent; (4) adjusting the paper feeding speed of the UV offset printing machine to be 7,000 to 12,000 pieces / hour, starting a UV drying system of the UV offset printing machine, adjusting the drying power of the UV drying system to be 2 to 5 Kw, and starting the machine to print. According to the printing process, the UV snowflake pattern is printed by adopting the offset printing machine, so that the consumption of the printing ink is effectively reduced, the printing efficiency is improved, and the UV snowflake pattern with a strong flash effect and three-dimensional effect can be generated by printing once.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a printing process for applying offset printing to complete UV snowflake patterns. Background technique [0002] UV snowflake pattern is a kind of surface treatment of printed matter by using UV snowflake ink to produce a printing effect with strong flash effect and three-dimensional effect. It is widely used in the packaging and printing fields of high-end tobacco, alcohol, cosmetics and tonics. In recent years, the printing process of UV snowflake patterns is mainly based on screen printing. The mechanism of producing snowflake patterns is the crosslinking reaction of the ink, and the adjacent or similar particles in the pigment are attracted to each other and solidified to form a fine texture. However, in this process of screen printing UV snowflake pattern, one printing can not produce obvious three-dimensional effect, and only two or three silk screen printing c...
