Today's printed matter has undergone great changes in the form of binding. For example, it can be used to bind double coils. It can be used for flat binding, and it can also use nylon-coated plastic threads. The following are the three common types of binding.
Flat order. When designing a flat-book, it is first important to note that there is enough room for binding between the order and the text. For example, if the O-spiral thread has a 3:1 ratio (3 holes per inch), you should leave 3/8 inch blank; and when the hole ratio is 2:1, leave a 1/2 inch blank.
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 milling back allowance on the back of the book, a 1/8 inch cut is also required on the other three sides of the book. In addition, a 1/4-inch rubberized area should be left in the lower part of the book cover to prevent the glue from seeping into the next book during the binding. The wireless adhesive binding process also requires the printing of the bleeding cover to be larger than the size of the text. a little.
Wireless adhesive binding. Although the cost and time required for wireless adhesive finishing seems to be somewhat incompatible with digital printing for the short-run printing market, some post-press binding companies have pre-made different colors, styles and different colors commonly used in digital printing hardcover. The size of the hardcover book case is used by digital printers, so wireless glue and adhesive hardcover have become a common binding method for digital printing. The
Different binding forms, the resulting binding effect is not the same, we can choose according to the specific situation.
