Its technical features are digital simulation design for product application, digital color management and printing process platform application, integrated product production and ERP and DAM production management. The main technologies and their development are summarized as follows:

Box design and 3d digital simulation

The folding carton printing production is printed in CIP3/CIP4 digital technology frame, and has incorporated the box design and 3d digital simulation into its production system. In the box type design and 3 d digital simulation, the software designer application, according to user's final demand as well as printing production process of folding carton production is decomposed into functional structure and its forming process design and surface finishing method design two links. With silk screen printing mesh, function structure and its forming process design is to meet the needs of the folding carton protection packaged products, and to determine the methods of die cutting and pasting box for the (given could satisfy the requirement of process after all kinds of digital control line, such as die tangent, tear line, line, etc.). The design of the surface finishing method should be based on the box type digital control line to design and beautify and display the product patterns and various finishing process lithography, so that the drawing text and the molding match. When two link is completed, according to the two types of data obtained, using three-dimensional digital simulation technology to simulate the actual effect and the folding method of folding carton Shanghai printing quotation, also can use in actual material samples on digital proofing technology application.

Pre-press production technology digital integration

The pre-printing technology of folding paper box can be summarized as: content expression digitalization, expression form color, functional structure personalization. And folding carton using digital integration of prepress production technology, based on the analysis of folding carton product benchmark graphic data, control data and equipment work, on the basis of the optimization method of graphic processing and typesetting printing everyday, make a description of the page content data, various kinds of process control and management of the data and processing data can flow to the transmission and transformation, realize the content description data, printing control data and processing data fusion.

The digital integration of pre-printing technology of folding paper box is mainly manifested in the following two aspects.

(1) the box type design data and the benchmark integration of prepress processing data in hangzhou in the design of folding carton printing, function structure and processing data and surface finishing processing data must be according to the performance of the prepress printing condition control benchmark for, to ensure that product design effect and the printing effect.

(2) the print data before and after printing, printing and its surface finishing process data integration, namely the data processing of box type design two-color printing presses, must be to deal with process after special processing, such as the pretreatment of the stamping parts. It is also necessary to use CIP3/CIP4 to directly generate printing ink quantity control data, die-cutting data and online quality control data directly from pre-printed data. Therefore, the control parameters of each quality control factor and process control point are set up to realize the stability of the equipment benchmark, the correct data transmission and easy to control.

The large - level printing of the printing technology and the digital control of the four-color printing press

Adopt by the large format printer (more than 740 mm * 1050 mm), large-format digital imaging equipment, CTP technology, wire processing technology, digital color management and digital production process system of the new technology of large-format three-dimensional printing, the printing technology is the application target of folding carton from beautification products to beautify the products and sales show an important symbol of unification.

At present, the global folding carton from the "quality, efficiency" to "quality, efficiency cost value-added" and requirements of high-end color of products with high quality, with the rapid development of market and product competition directly triggered with technology and value-added products competitiveness promotion combination of large-format printing technology and digital control. Its technical features are mainly manifested in the following aspects.

(1) digital integrated printing operation is adopted. It will force enterprises to raise the technical threshold label exhibition and realize the change from traditional experience to digital management.

(2) establish an innovative production model based on product guidance market. That is to achieve the integration of data from data to product, and break through the printing quality bottleneck of folding carton in the production of large and high yield.

(3) competition from single-factor competition to comprehensive ability competition. The folding paper box market is being subdivided and integrated, so that the printing personnel, enterprise resources and process technology must be innovated.

After printing, the wire production and automatic discharge

In the process of printing and printing of folded paper box, the technology development trend of improving product quality and production efficiency is to use wired production and automatic exhaust. Among them, the folding carton postpress attachment production mainly include the attachment surface finishing, such as hot stamping, polishing, local UV glazing flexible printing, the most representative has Roland 700 attachment cold seal device. The automatic discharge of automatic discharge based on the quality of product printing is mainly based on the automatic discharge and automatic discharge. Based on the quality automatic discharge, the quality deviation of the sample and the standard is compared with the density detection or chromaticity test, and the method of double charge is used to eliminate the waste, such as the wire detection device of Roland 700. Based on the position error of automatic waste refers to the die cutting, stamping, etc. In the folding carton postpress jiaxing printing, according to the position of sample and standard error, adopts double receiving method to eliminate waste, such as Bosch, automatic die-cutting machine exhaust device.
