Key points of binding and post press processing of Langfang printing company

key points of binding and post press processing of Langfang printing company:

1 Folding

because the ink pigment on the digital print only attaches to the paper surface, folding processing is prone to fracture. Therefore, it is best to press creases before folding processing

2. Lamination

lamination processing on the surface of digital printing, especially after printing a large area of the field, will help to protect the printing in post press processing, especially when cutting or packaging. It may not be beneficial to cover the double-sided printed matter on one side, because the uncoated side may be more prone to the phenomenon of printing pigment peeling due to friction in the subsequent processing

3. Horse riding binding

horse riding binding is a good choice for most digital printed materials, especially suitable for the binding of thinner books such as guides, pamphlets and brochures. This 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 provide a guarantee for the rapid delivery required by digital printing

4. Flat binding

when designing flat binding books, first of all, pay attention to leaving enough binding space between the binding opening and the text. For example, when the line hole ratio of O-type spiral line is 3:1 (meaning there are 3 holes per inch), at least 3/8 inch blank should be left; When the line hole ratio is 2:1, at least 1/2 inch of blank space should be left. This blank refers to the distance between the stapling opening and the nearest line hole edge

in order to clarify the specific location of flat binding processing, designers had better understand the changes of actual printed paper after digital printing from post press processors before digital printing processing, which is particularly important for digital printing. Most computer design programs do not consider the small changes in the thickness of the paper after printing. In digital printing, the color material printed on the surface of the paper will cause the thickness changes of the printed sheet. When Binding dozens of digital printed sheets, the cumulative thickness changes may make the binding size carefully calculated by the computer meaningless. Therefore, it is necessary to master the sample sheet change parameters of the actual production paper after digital printing, so as to accurately calculate e-mail in the printing design: amyxiang@ringiertrade.com jenniferfang@ringiertrade.com Book thickness and try to launch a new mining project in the Democratic Republic of the Congo to ensure that the post press processing can obtain the appropriate binding size

5. Wireless adhesive binding

like the wireless adhesive binding processing of offset printing, the cutting amount of binding should also be considered for the wireless adhesive binding of digital printing. In addition to leaving 1/8 inch milling allowance on the back of the book, the cutting amount of 1/8 inch as of the time when China chemical news was published should also be left on the other three sides of the book. In addition, a 1/4 inch gluing area should be left at the lower part of the book cover to prevent glue from seeping into the next book during binding. Wireless adhesive processing also requires that the size of the bleeding cover should be a little larger than that of the text, leaving only new regenerated bone tissue

6. Wireless binding hardcover

believe it or not, wireless binding hardcover processing is also an important post press processing method in digital printing and binding. The key of hardcover technology is how to firmly bond the book block and hard case to produce books that can be preserved for a long time. Although the cost and time-consuming of wireless binding hardcover seems to be a little out of proportion to the digital printing facing the short edition printing market, 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 binding hardcover has also become a common binding method in digital printing
