Printing technology experience

Not sure, so put aside, not only the product is easy to deformation, but also affect the progress of the order, to the factory brought unnecessary trouble.

Printing Equipment:

Again, we need to wash the pre-press processing and post-press processing. Prepress processing is an important part of print production, including a variety of content, including prepress image processing, color separation, plate making and proofing content, but also including lithography, relief plate, gravure plate, screen plate several different plate making methods. And we learned how to do it.

Relatively speaking, post-press processing is more cumbersome, and post-press processing is the production process that makes the printed matter obtain the required shape and performance, such as: stitching: refers to the position of the book should be linked. Front mouth: also known as the mouth, refers to the reading and reading edge relative to the stitching edge. The margin between the top line of a book's text and the edge of the page. Base: The margin between the bottom line of a book's text and the bottom edge of the page. Back: also known as the back, refers to the flat part of the book that needs to be glued (or bound) after the book. Hardcover books have round backs and square backs. Title page: A sheet of paper with the title, publisher's name, and author's name on it. Some books have the backing paper and the title page printed together: the cut appears uneven knife marks. Small page: A page in a book that is smaller than the cropped size. Square back: a kind of hardcover. The back of the book is straight and perpendicular to the back cover. Corner wrapping: To wrap a layer of leather or fabric over the front corners of a book's cover. Book groove: also known as book groove or groove, refers to the groove where the cover and back cover are pressed into the connecting part of the spine after the hardcover cover is closed. Stitch distance: The distance between two adjacent stitch positions on the same book thread in the stitching. The number of stitches: In the sewing of the lock thread, the number of needle eyes of the book sewing and countless tedious links.

Finally, we learned about printing and making up. Printing is the process of transferring information from negative or positive negatives to plates or other sensitive materials by means of contact exposure. Printing plate is to separate the graphic dot on the original picture of the plate, transfer to the printing plate with a photosensitive way, for lithography printing, but also to make the graphic dot part of the plate with inophilic performance, the blank part has a hydrophilic exclusion ink performance, this image transfer procedure, for lithography printing plate. Only the original picture is printed into a printing plate, the formation of inked pictures, and then transferred to the paper through printing, in order to complete the reproduction of pictures and texts. Plate printing is a bridge process between plate making and printing. On the color separation plate, it is required to transfer the text and text of the original picture without deformation. Under the printing, the ink performance of the graphic part and the hydrophilic energy of the blank part are required to be clear, and at the same time, it must be able to withstand tens of thousands of times of stamping friction without changing its ink and hydrophilic energy. However, as an intermediate transfer process, change is bound to occur, in order to obtain its stability and less change, it is necessary to control the plate photographic performance, plate printing operation process, image transfer data, and the adaptation performance of printing, etc., in the overall specification data of the plate printing process to ensure smooth and good reproduction. Printing in the entire copying process to go through two times, a printing version, a printing version. Therefore, printing is very important in the entire reproduction process, and its quality directly affects the quality of printing and printing efficiency. However, there are many problems in the current printing process, such as proofing and printing most of the use of different plate materials, the dot changes of the two are very different; The dot expansion of proofing and printing is not consistent, which needs to be adjusted reasonably by printing plate; The quality of the printing plate itself is unstable, resulting in more rework. Therefore, it is an urgent and important task to strengthen the standardization of printing process and data quality management to achieve stability and optimization of the quality of printing.
