2Digital Printing's Postpress Methods and Technical Points
3. Saddle stitching
Saddle stitching is a good choice for most digital prints and is particularly suitable for the binding of thinner books such as guides, booklets and brochures. The binding method is economical and practical, and can be carried out online with other processing methods. Simultaneous post-press processing of folding, folding, binding, and online cutting can be performed, which can provide guarantee for fast delivery required by digital printing.

4. Set flat
When designing a flat-book, the first thing to note is that there is enough room for binding between the order and the text. For example, when the O-spiral thread has a 3:1 ratio (3 holes per inch), Leave at least 3/8 inch of blank space; when the ratio of holes is 2:1, leave at least 1/2 inch of blank space. This blank refers to the distance between the mouth and the nearest line edge.
In order to clearly define the specific location of the processing, the designer is better to understand the changes of the actual printing paper after the digital printing before the digital printing process, which is particularly important for digital printing. Most computer design programs do not consider slight changes in the thickness of printed paper. In digital printing, the color material printed on the surface of the paper causes a change in the thickness of the printed sheet. When the digital printed sheets are bound in tens of pages, the accumulated thickness Changes may make the computer's carefully calculated binding size meaningless. Therefore, we must master the proof change parameters of the actual production paper after digital printing in order to accurately calculate the thickness of the book during the printing design, so as to ensure the proper binding size after the printing process.
5. Wireless glue binding
As with adhesive offset printing, digital glue bindings also need to consider the amount of cutting. In addition to leaving a 1/8-inch back allowance on the back of the book, a 1/8-inch cutout is also required on the other three sides of the book. In addition, a 1/4-inch glue area should be left in the lower part of the book cover to prevent glue from seeping into the next book in the binding. Adhesive adhesive processing also requires that the print cover should be larger than the text size.
6. Wireless adhesive binding hardcover
Whether you believe it or not, wireless glue binding is also an important post-printing method in digital printing binding. The key to the hardcover process is how to securely bond the book block to the hard case and produce books that can be stored for long periods of time. Although the cost and time required for adhesive binding of wireless glue seem to be somewhat out of proportion to the digital printing for the short-run printing market, some post-print binding companies prefabricate different colors, styles, and differences commonly used in digital printing. The size of the hardcover bookcase is used by digital printers. Therefore, wireless adhesive binding has also become a common binding method for digital printing.
