Layout design is the key. Most binding methods have defined margin sizes suitable for their binding methods. Of course, for some carefully designed products or products with more complicated die-cutting procedures, the folding rules can be adjusted. A small change in layout design can turn high-speed and smooth automation products into costly and time-consuming manual products.
Many high-speed printing presses can automatically collate pages after printing. This saves time for some production links, but may extend the cycle in other links. For example, in the case where the index and the content are separated, although the index has to be manually paged, both the index and the content need to be punched automatically.
Pre-collation is also bad for some machine-bound jobs. For example, the thick cover of a spiral bound book needs to be punched separately from the inner pages of the text before collating and binding.
If this batch of jobs needs to be indexed, especially when bound with a ring binder, it is a good way to strengthen the index. Polyester film is a laminated sheet that can be used for the index part and the spine part to ensure that the index is not damaged too much under high usage. Polyester film can also provide a variety of colors to match the rest of the book.
Keep the glued part free from ink, toner and coating. Any material that is bonded by paper bonding can be done by gluing. For some packaging boxes and folders, all glued parts must be free of ink, colorant and paint.
Laminating is a good way to make the cover and other parts of the book strong and durable. However, because the chemical composition of the colorant is not compatible with many kinds of coatings, problems occur in the binding process. Fortunately, there are some coating materials that are specially used in conjunction with colorants. Therefore, you should communicate with the binding factory or the finishing department before printing to avoid problems in the subsequent production process.
Thick substrates require indentation. When the text is printed on paper of 128 g/m2 or more, or paper with a thicker ink covering layer, it is necessary to indent before folding. Depending on the quality and printing requirements, the creasing can be done during the folding process, or as an independent production step.
