Description

Description Method for realizing online printing of changed content and hybrid digital printing system [1] Technical field

[2] The present invention relates to a method of implementing on-line printing of changed content on a rotary press and a hybrid digital printing system.

[3] Background Art

[4] Traditional printing methods include: offset printing, flexo printing, embossing, gravure printing, gravure printing, silk screen printing. Each has its own advantages, such as offset printing, which is advantageous in printing precise halftones, uniform gradation and high definition; while flexo printing is good at solid printing, metal ink printing, partial glazing, etc. Metal ink printing, security printing, solid printing have advantages and thicker ink layer thickness; line gravure printing is unique in line printing and security printing; screen printing is in ink layer thickness, metal ink and special There are special features in printing effects. In the past, in order to make the printed products have the comprehensive advantages of the above several different printing methods, most of them are used on different single machines, and printed many times, such as offset printing machine printing related content, and then using flexo printing machine, embossing machine, The gravure press, the line gravure press or / and the screen printer print out other relevant content in order to print the perfection of the product. However, the drawback of this multiple printing method is obvious. When the substrate is printed many times, it will be deformed, resulting in inaccurate overprinting and an increase in the reject rate. If a substrate is used in a separate press, after multiple printing and post-press processing, the production efficiency is very low. In addition, since printing products using a separate paper printer, it is necessary to go through multiple printing processes and post-press processing, and the storage of semi-finished products is a relatively big problem for enterprises. Because the storage environment of the semi-finished products should be the same as the printing environment, otherwise the product quality is difficult to guarantee.

[5] In order to solve the above problems, a satellite rotary printing machine has been invented. The satellite rotary printing machine has the following features. The modular design is to make any printing unit or post-press processing unit into a single module. Installed in the necessary position as needed, this modular structure enables different combinations of modules and can be placed anywhere the customer wants. The general satellite rotary press can perform various printing functions such as offset printing, flexo printing, embossing, gravure printing and silk screen printing at one time. Previously, most of these satellite rotary presses relied on imports. However, they have been completely localized in recent years, and their prices are much cheaper than similar foreign products. At present, most domestic satellite rotary presses are used in China. Now Some rotary presses are only suitable for large-volume and long-term product printing.

[6] Whether it is a traditional stand-alone rotary press such as offset press, flexo press, embossing machine, gravure press, or screen printing machine, or imported or domestic satellite rotary press, they cannot be directly used at one time. Printing has changed content, and the changed content needs to be completed by another independent digital printing device, especially for content with color change, and more needs for multi-color digital printing equipment. If the digital printing equipment is also designed to be modular, and combined with an offset press, flexo press, embossing machine, gravure press, screen printing machine or satellite rotary press to achieve printing with changing content, but Since the current speed of digital printing equipment is fixed, the printing speed of existing offset presses, flexo presses, gravure presses, screen printers or satellite rotary presses needs to be changed, that is, at the beginning of printing, In order to observe the print quality manually, it is necessary to print at a lower speed for observation, and once the printing is normal, in order to improve the production efficiency, it is necessary to print at a higher speed, and now the speed of the rotary printing machine can be mostly at 0 m/min. Adjust to within 100 m/min. This makes it impossible for existing rotary presses to directly interface with digital printing equipment, and has to use separate digital printing equipment to print printed materials with changing content, such as the current large number of electronic surveillance codes that need to be printed, mainly 釆Printed in this way.
