Analysis on Key Points of Post Printing Binding in Digital Printing

       Only by carefully designing and arranging the printing from the beginning can we ensure the harmony between printing and post press processing.Analysis on Key Points of Post Printing Binding in Digital Printing

Analysis on Key Points of Post Printing Binding in Digital Printing

During production, the following points shall be noted:

1. Folding

       Because the ink pigment on the digital printed matter is only attached to the paper surface, folding processing is easy to break. Therefore, it is best to press creases before folding processing.

2. Film covering

        Laminating the surface of digital printing, especially after printing a large area of field, will help to protect the printing in post press processing, especially in cutting or packaging. It may not be beneficial to cover double-sided printed matter on one side, because the uncoated side may be more prone to peeling off of printing pigment due to friction in subsequent processing.Analysis on Key Points of Post Printing Binding in Digital Printing

3. Riding order

      Horse riding binding is a good choice for most digital printed materials, especially for the binding of thinner books such as guides, brochures and brochures.Analysis on Key Points of Post Printing Binding in Digital Printing

      The binding method is economical and practical, and can be carried out online with other processing methods. It can carry out the post press processing of page matching, folding, binding and online cutting at the same time, which can ensure the rapid delivery required by digital printing.Analysis on Key Points of Post Printing Binding in Digital Printing 

4. Flat binding

      When designing a flat bound book, first pay attention to leaving enough binding space between the binding opening and the text, for example, The wire hole ratio of O-type spiral wire assembly is 3:1 (there are 3 holes per inch), 3 / 8 inch blank should be left; Analysis on Key Points of Post Printing Binding in Digital Printing

      when the line hole ratio is 2:1, 1 / 2 inch blank should be left. Most computer design programs do not consider the small change of paper thickness after printing. In digital printing, the color section printed on the paper surface will cause the change of sheet thickness. Analysis on Key Points of Post Printing Binding in Digital Printing

      When several pages of digital printing sheets are bound, the accumulated The thickness variation may make the binding size carefully calculated by the computer meaningless.Analysis on Key Points of Post Printing Binding in Digital Printing

       As with the offset binding process, the cutting amount of binding should also be considered for the wireless binding of digital printing. In addition to leaving 1 / 8 inch milling allowance on the back of the book, 1 / 8 inch cutting amount should also be left on the other three sides of the book. Analysis on Key Points of Post Printing Binding in Digital Printing

     In addition, a 1 / 4-inch gluing area shall be reserved at the lower part of the book cover to prevent the glue from seeping into the next book during binding. The wireless adhesive binding process also requires that the bleeding cover should be a little larger than the text size.Analysis on Key Points of Post Printing Binding in Digital Printing

      The key of hardcover technology is how to firmly bond the book block with the hard case to produce books that can be preserved for a long time. Although it seems that the cost and time of wireless adhesive binding hardcover are not commensurate with the digital printing facing the short print market.Analysis on Key Points of Post Printing Binding in Digital Printing

     some post press binding enterprises have prefabricated hardcover cases of different colors, styles and sizes commonly used in digital printing hardcover for digital printers to choose, Therefore, wireless adhesive binding hardcover has also become a common binding method in digital printing.Analysis on Key Points of Post Printing Binding in Digital Printing
