In the process of digital printing post-press processing, due to the digital printing printing quality has the characteristics of different from traditional printing printing quality, there are quite a few place need to pay attention to.

Experience a: unfavorable effect immediately after printing

Technology introduction: is the plastic mulch on print surface form the unity of paper-plastic print.In the printing surface covered a layer of transparent plastic film, can strengthen the printing surface brightness, wear-resisting, waterproof, prevent heat, anti-fouling, etc.

Problem description: after coated on digital printing printing quality, printing quality can appear the phenomenon of blister, this is because the digital printing ink layer containing silicone oil, usually glue can't normal penetration ink layer.

Solution: adjust the part in the process of digital printing production process, try to print in place for a period of time after printing to coated.

Experience 2: die-cutting and creasing emphasizes accuracy

Process description: the specific use of paper or cardboard according to certain specifications, with a knife cut into certain shape process for die cutting;Using steel wire according to certain specifications, the pressure on the paper or cardboard imprint, in order to take advantage of the imprint the paper or paperboard bending, this method is called indentation.

Problem description: at present, with the personalized packaging products, small batch and variable demand, part also USES digital printing printing packaging products.Bending of packaging products, combining site need to die cutting, indentation process implementation.Die-cutting, indentation common wrong size, finished product skewed or overlapping not beautiful modelling problems are largely related to the size is not accurate.

Solution: layout should be strictly according to customer processing requirements such as size calculation, measurement, review and make real samples, to avoid error influence use, and cause big loss.

To experience three: hot melt adhesive temperature control good

Technology introduction: gum is to put the printed paper, including illustrations, cover, etc., according to the different size specifications to fold into a book, after pressing, gluing, cutting and a series of process, finally make it into a book.Simple process, mature technology, low cost, high binding efficiency.

Problem description: binding quality fit and unfit quality directly related to the quality and appearance of the books and periodicals, the temperature is too high, easy to aging, rubber doesn't work;Temperature is too low, the phenomenon such as glue, paper.

Solution: use hot melt adhesive glue order, before production will hot melt adhesive heated to a certain temperature, general control between 150 ~ 200 ¡æ, the best temperature in 170 ~ 180 ¡æ, and to maintain the stability of the temperature.
