From the perspective of binding and post-press processing, there are still some details that cannot be ignored in the post-press processing of digital printing. Now we discuss the post-press processing methods of digital printing, and hope that these contents can provide some reference for digital printing industry. Consider pre-press processing from pre-press design Prepress design will help the successful completion of digital printing postpress processing. In digital printing, the quality of pre-press design has a great impact on post-press processing costs. Due to the limited paper specifications used in digital printing, and a large number of digital prints are single-sided printing, in addition to requiring the pre-press design of digital printing to make the most effective use of paper, the following factors should also be considered. 1. Paper thread direction Where possible, try to make the direction of the paper strands consistent with the back of the finished book. Due to the particularity of the combination of the color material on the surface of the digital printing paper and the paper, if folded in the direction of the horizontal thread, the image is likely to break at the folded position. Therefore, the digital print should take into account the post-press processing technology when designing the pre-press. 2. Image position on the printed sheet Usually, many digital prints design the image in the middle of the printed sheet, but only find out that it wastes a lot of time and money when doing post-press processing after printing. For example, if you design an image with a size of 210 × 285mm on a frame with a size of 450 × 320mm, you need to cut all four sides of the printed sheet; but if you place the image at a certain corner (such as the upper left corner) ), You only need to cut both sides, which saves post-press processing time and reduces printing costs. However, if the other two sides of the image are bleeding designs, you still need to trim all four sides of the printed sheet. The main points of binding and post-press processing Only by carefully designing and arranging the printing work from the beginning can the harmony between printing and post-press processing be guaranteed. In production, the following points should be noted. 1. Fold Because the ink color material on the digital print only adheres to the surface of the paper, the folding process is prone to breakage. Therefore, it is better to press the crease before folding. 2. Laminating Laminating the surface of digital prints, especially after printing a large area, and then laminating, will help protect the printed matter in post-press processing, especially when cutting or packaging . It is not necessarily advantageous to apply a single-sided coating to a double-sided printed product, because the uncoated side may be more prone to peeling of the printing color due to friction in subsequent processing. 3. Saddle stitch Saddle stitching is a good choice for most digital prints, especially suitable for the binding of thin books such as guides, brochures and brochures. The binding method is economical and practical, and can be carried out online with other processing methods. It can perform post-press processing of collation, folding, binding and online cutting at the same time, which can provide guarantee for the fast delivery required by digital printing. 4. Flat book When designing a flat booklet, first of all, pay attention to leave enough binding space between the binding opening and the text. For example, when the thread-hole ratio of the o-spiral is 3: 1 (referring to 3 holes per inch), it should be Leave at least 3/8 inch blank; and when the line-to-hole ratio is 2: 1, at least 1/2 inch blank should be left. This blank space refers to the distance between the stitching edge and the nearest line hole edge. In order to clarify the specific position of the bookbinding process, it is best for the designer to understand the changes of the actual printing paper after the digital printing before the digital printing process, which is especially important for digital prints. Most computer design programs do not consider small changes in paper thickness after printing. In digital printing, the color material printed on the paper surface will cause the thickness of the printed sheet to change. When binding dozens of digital printed sheets, the cumulative thickness The changes may make the binding size carefully calculated by the computer meaningless. Therefore, it is necessary to grasp the sample change parameters of the actual production paper after digital printing in order to accurately measure the thickness of the book during the printing design and ensure that the post-press processing obtains a suitable binding size. 5. Wireless glue binding Similar to the wireless binding process of offset printing, the wireless binding of digital prints should also consider the amount of binding. In addition to leaving a 1 / 8-inch milling back margin on the back of the book, a 1 / 8-inch cutting volume should also be reserved on the other three sides of the book. In addition, a 1 / 4-inch glue area should be left at the bottom of the book cover to prevent glue from seeping into the next book during binding. The wireless glue binding process also requires that the printed bleeding cover should be a little larger than the text size. 6.Wireless glue binding hardcover Believe it or not, wireless glue binding hardcover processing is also an important post-press processing method in digital printing and binding. The key to the hardcover process is how to firmly bond the book block to the hard book case to produce a book that can be stored for a long time. Although the cost and time spent in wireless binding and binding hardcover seem to be somewhat unequal to digital printing for the short-term printing market, some post-press binding companies have prefabricated different colors, different styles and different commonly used digital hardcover The size of the hardcover book case is for digital printers to choose. Therefore, wireless adhesive binding hardcover has also become a commonly used binding method for digital printing. Integrated post-press processing solution The quality and speed of digital printing make it more eye-catching and become one of the increasingly widely used printing methods, and most digital prints almost need to be processed after printing to become a practical printed product, and most post-printing The processing technology can be applied to the post-press processing of digital printing. In order to meet the requirements of customers for quality and speed, many digital printing companies have purchased a wide range of post-press processing equipment to form a complete post-press processing solution, which has also become a powerful weapon for these companies to participate in market competition.
