4. Combined printing and on-line processing With the improvement of the quality of printed matter, printing technology is also moving in a more complicated direction. On the one hand, rich and diverse printed materials have led to the complication of the printing process. On the other hand, the combination of printing processes and On-line finishing and molding processing also create more beautiful prints. Combined printing and on-line processing have become the focus of most printing and printing press manufacturers today. The advantages of this form are: the diversity of the printing system; the increased flexibility of the printing method; the increase in the value-added of the printed product; and the exquisiteness of the printing quality.
Combination printing can include offset printing, flexo printing, gravure printing, screen printing, digital printing and other printing methods. Combining a variety of printing forms and processes to avoid the deficiencies of a single printing method, a variety of effects of a complete print product perfect, especially in the printing of bills, high-end packaging products, cigarette packets and other widely used.
On-line processing is reflected in prepress processing and postpress processing. It can be used for coating, compounding, transfer, and polishing, hot stamping, film lamination, die cutting, embossing, folding, and cutting. The functions are combined in one production line to form a variety of production capabilities so that the products can be completed at one time, which can increase production efficiency and reduce waste.
(1) Polishing Polishing applies a layer of colorless and transparent coating on the surface of prints. After leveling, drying, and calendering, a thin and uniform transparent bright layer is formed on the printed surface. The lacquer coating layer has high transparency and smoothness, makes the surface of the printed product have a beautiful luster, improves the surface properties of the printed matter, and protects the printed graphics. It is widely used in packaging decoration, books and magazine covers, albums, trademarks, advertisements. , large-scale decoration and other printed products.
Modern offset presses have adopted the coating machine as a standard configuration, and even equipped with double coating units, can also achieve UV printing of printing materials such as plastics, paperboard, etc., and the printing format is also expanded to the following four or super large format to meet the needs of customers. More demand.
The glazing form is usually applied by an anilox roller-coated roller glazing and a knife-type glazing with an enclosed knife cavity to ensure the smoothness of the glazing and the precise control of the amount of varnish.
(2) Curing device UV curing is generally applied to UV coating. The coating is a mixture of active monomers or oligomers that can be polymerized by free radicals. During the curing process, the coating is irradiated with ultraviolet light. , Generate free radicals or ions and cross-linking reaction, the formation of solid polymer, thereby completing the coating process of curing. This drying method has a bright future. UV gloss gloss is good, in line with environmental requirements.
(3) Cold Stamping Device Cold stamping printing process is a process for printing and stripping of electro-aluminum foil using UV glue. First apply the adhesive on the graphic area where the substrate needs to be stamped. Apply pressure and peel off the roll to make the foil transfer to the print surface. The entire process does not require heating and the cost is low. Online hot stamping is the addition of a cold stamping machine on the offset printing press. Hot stamping can be performed before or after printing.
(4) Cutting device On-line cutting uses web feed paper, which can be printed on a single sheet after cutting. This form of paper feeding saves 20% of the cost and was used in the dripa2004 offset press in Heidelberg. The dredgea2008 Roland 700 sheetfed offset press is also equipped with such a cutting device. KBA's online cutting device is located on the impression cylinder of the last unit and performs online cutting of prints.
(5) Post-press molding on-line processing Post-press molding on-line processing Various box types can be processed online, such as straight boxes, lock-bottomed paper cassettes, double wall paper cassettes, envelope-type paper cassettes, sandwich-type paper cassettes, and square boxes , hexagonal boxes and so on. The folder-gluer includes conveying, folding, lock-bottom and other mechanisms, requiring accurate processing position, firm bonding, and adjustable size and size. (Finish)
