subject: On The Label Printing Process Characteristics And Note [print this page] Is to mark the so-called label printing, labeling, advertising space patterns printed on paper in the special compound, the compound is based on good quality paper, tissue paper (the back) painted quit Glue After the adhesive on the bottom surface of waxed paper. Use, as long as the paper peeled off the bottom, you can put the stickers printed with graphic paper, pasted directly on the goods or other objects. As the stickers printed with the exposed tear easily, strong adhesion, flexibility, adaptability, easy to paste a row many times, it is widely used for social and economic life, market prospects are bright.
Present, label printing there are two processes by offset printing and letterpress, rotary machine structure points, round flatten flatten three kinds of stamping the form of peace.
Printed pages and other large products, such as advertising, using rotary or round flattened offset, letterpress printing machine, product quality and printing efficiency can be quite satisfactory results. The small format of the structure and needs more make-cutting, stamping the mark, label products, the most appropriate use of self-adhesive label printing presses. Such machines are plastic, two presses of the uniform convex ink printer together with the characteristics of a machine, using roll-type adhesive paper, can be a complete multi-color printing, hot foil, laminating, die cutting, rewinding such as scrap and cutting process. The machine can use the metal plates and resin printing, thanks to modular structure, can print a characteristic change in a flexible and convenient features. Feeding the machine structure and revenue structure and aniline printing paper similar, the difference is that, in addition of the moving process can be controlled Paper Step printing. The agency requires a strict time control and position control, otherwise it will affect the accuracy of overlay.
Web sticker printing paper to the general printing methods, it is moved axially to achieve overlay of tabbing. Ie plate cylinder at the same time loaded with three overlay version, when the adhesive paper embossed platform in a move every jump, plate cylinder rotate back and forth along a horizontal direction, on the realization of a color print. Three-color overlay label printing, sticker paper, the platform must move three times to complete the full-page overlay work. Print advantage of this structure is to simplify the device structure, reducing the size of the machine, but because of the printing stroke short, Indian product is not dry and not conducive to the completion of a large area of wet wet trapping pressure, but more suitable for a small area of trapping or chromatography. Structure from the imprint of view, self-adhesive round Pressing Machine Printing quality than platen machines well, particularly in the printing field layout, the ink can be achieved even without a good solid results. The platen structure of adhesive machine, printing easy for a large area on the ground version of page (printed materials) presents "You Hua" like ink, print quality is not satisfactory, only a small layout for printing.
After the completion of the printing adhesive products can also be conducted on-line hot stamping, laminating and die cutting, slitting process. Online simultaneous operation of adhesive products, layout design should give full consideration to the device features the best of the field layout system to avoid trapping a large area, so that printing, hot stamping, laminating can get good results.
Hot foil adhesive products to capture market advantage is essential for a process. Etching adhesive, adhesive plastic film products used in the appropriate forum Foil To be decorated, will greatly enhance the value-added goods. However, if the process properly, film adhesive foil Stamping Flooding occurs, such as layout, foil attachment is not strong, burr edge issues such as layout, will seriously affect the image of the product market. Therefore, the background ink is not printed too thick, deep process should try to make it thin and India ink, ink that is necessary to adjust depth and hue, the printing ink layer corresponding to those able to achieve the original thin requirements, and facilitate the aluminum foil strong adhesion, while not produced in Latvia The background color ink stamping defects. To make hot foil layout clear, zincograph to a suitable depth of some corrosion to parts stamping blank page and a certain amount of height difference, from the eye to avoid. As the hot foil printing pressure than the pressure corresponding to bigger, in order to avoid distortion caused by packet compression foil lining the edge of burr generated layout, including pads (pads) should be used in rigid material, the deformation coefficient, roughness, to ensure hot India effect of making the same batches of product quality. In addition, if adverse effects of hot stamping, stamping does not occur, the blur, when the attachment is not strong and other defects, process measures can not overcome the above situation can be considered a good replacement and the quality of hot foil, to improve the stamping effect.
As long as we correctly know and understand the principle and process of self-adhesive printing process, and considering the various impacts the quality of the circumstances and reasons, and to take appropriate technical measures, they will print the product quality as the market welcomed the kinds of stickers printed.
