The invention relates to the technical field of printing, in particular to a production process of a personalized packaging bag, a personalized label or a personalized transfer film.
Background
The common printing methods include four major types, namely letterpress printing, intaglio printing, lithographic printing and stencil printing. Because gravure printing can completely express continuous tone and rich layers of originals through ink layers with different depths, the ink is thick, bright in color and rich in stereoscopic impression, and therefore flexible printed matters such as packaging bags, labels, transfer printing films and the like are mainly subjected to gravure printing. However, before gravure printing, a plate needs to be made for patterns or characters to be printed, drying and overprinting are needed after printing of each color, a coil stock is unreeled and printed through a printing roller during printing, and the coil stock is reeled after printing is completed, so that the process is complex, the coil stock is only suitable for long-plate printing and large-batch printing, the production cost of a small amount of diversified printed matters is greatly increased due to plate making, plate replacement and printing again, the economic benefit of an enterprise is not improved, and the sizes of rolled printing materials are fixed, are not convenient to adjust and are not convenient to manufacture into personalized shapes.
With the progress of social technology, a digital printing machine represented by HP indigo series appears, the printing machine adopts full-digital information transmission, complex plate making and overprinting processes in the intaglio printing process are omitted, the pictures and texts of digital information can be quickly printed on a printing stock, and the quick and low-cost printing of personalized pictures and texts is realized. However, the printer can only print the pictures on a printing stock with certain thickness and stiffness, and can not print the pictures on the flexible base material.
