Cold stamping process
Heidelberger Druckmaschinen AG has developed an innovative cold stamping process for its time-honored offset press, which has a low ability of independent innovation and few advanced and personalized special varieties for the current development of the domestic plastic machinery industry. The cold stamping module applicable to the syba CD74 and CD102 series printing machines can perform post press processing with metal texture on any substrate with a gram weight of g/m2, and presents a gorgeous high-quality effect. Label, packaging and commercial printing enterprises can use this technology to meet the growing market demand for excellent surface finishing effects
compared with hot stamping, cold stamping technology has some important advantages. The use of traditional offset printing plates saves preparation time. At the same time, this new technology can achieve a printing speed of 15000 sheets/hour and achieve accurate registration. The application effect of the cold stamping process in cutting off the power supply on the fine structures and components such as text, lines and diagrams is very ideal, and it is suitable for short edition and frequent replacement
Sebastian wolf Co., Ltd., located in eltville, is a very professional printing enterprise. Alessandro Compagni, President of the company, said, "I believe our customers will be very satisfied with the products with this new stamping technology." The company has 44 employees, and its Suba CD74 is equipped with a cold stamping module. Using this new technology saves a lot of homework time, which makes Mr. Compagni very happy. He explained, "the speed of CD74 production (whether offline or offline) is much higher than that of hot stamping before."
this cold stamping technology requires two units. The first unit applies the adhesive to part or all areas of the print through the traditional offset printing plate; The second unit combines the cold stamping module and the metal foil conveying system to store this calibration value with the receiving unit. The metal foil passes through the imprint line between the rubber drum and the imprint drum. The pressure of the rubber blanket transfers the metal layer on the metal foil to the part coated with adhesive on the surface of the print. The base of the metal foil is removed, and the metal layer remains on the surface of the print. In addition, after cold stamping, these two units can also be used for traditional offset printing
