Embodiment Construction

[0020] Such as figure 1 As shown, the molding-gravure printing integrated machine consists of an unwinding device 1, a molding device 3, a printing device, and a winding device 5. The printing carrier is sequentially connected to the unwinding device 1, molding device 3, printing device, and winding device through a transmission shaft Device 5; the molding device 3 includes a holographic embossing roller 3-1 and a pressure roller 3-2, both of which are arranged tangentially, and the printing carrier enters the printing device after being molded by the molding device 3; the printing device consists of two groups of printing units ( 4, 4'), a drying device (4-3, 4-3') is provided at the rear of each printing unit (4, 4'), and a drying device (4-3, 4-3') is installed on each printing unit (4, 4'). There are photoelectric tracking devices (4-1, 4-1').

[0021] The roll printing carrier is placed on the unwinding device 1, and enters the molding device 3 through the transmission s...

Abstract

The invention relates to a method for performing positioning chromatography on holographic information and color printing information, which belongs to the technical field of anti-counterfeit printing. The method is characterized by comprising the following steps of: impressing laser holographic information on an aluminizer film or an alumite material on a mould-pressing and intaglio-printing integrated machine by using a mould-pressing device; and printing the color printing information on the aluminizer film or the alumite material by using a printing device, wherein mutual positioning chromatography is performed on the laser holographic information and the color printing information. In the method, the defects in the prior art are overcome; mould-pressing and printing integrated production is realized, and off-line secondary printing is avoided; pattern chromatography is accurate and continuous; and the rejection rate is low. The method is suitable for the repositioning printing of plastic film products after mould pressing.

Description

technical field [0001] The invention belongs to the technical field of anti-counterfeiting printing, and in particular relates to a method for positioning and overprinting holographic information and color printing information. Background technique [0002] The Chinese patent with the publication number CN1313578A discloses a printing method of holographic images and characters, which includes the following steps: A. making a positioning holographic plate; B. embossing holographic information and characters on the substrate; C. combining holographic images and characters with ordinary The images and texts are registered and printed, and the registration methods include mechanical registration and photoelectric registration. The paper is accurately positioned at a certain position through the regular positioning device; the photoelectric automatic registration reads various colors through the light head, and the computer system judges the registration error and the amount to ...
