[Chinese Packaging Network News] In the entire printing process, we call the design, plate making and other technologies the prepress, the printing is called the main printing, the indentation, folding, die-cutting, etc. are called after printing, and can be printed The former, main printing, and post-press segmentation are concerned with the development trend of digital printing.
Before the printing, the design part has basically been digitized. The design has been inseparable from the computer and can not be separated from the network. In the platemaking technology, offset printing, screen printing film production, gravure printing engraving technology, flexo printing engraving technology has also been widely used. However, traditional offset printing PS printing and printing techniques, gravure printing and flexo printing etching, and traditional techniques and techniques such as screen printing and photolithography are still in use. Such processes and techniques are more or less used. Three wastes will be produced, causing environmental pollution.
At the same time, there are new technologies and processes to replace them, such as CTP computer direct plate-making technology in the offset printing process, digital printing technology without a plate (possibly replacing screen printing), and so companies engaged in backward technology and technology are already It's time to "force it".
The main printing process has already been analyzed before. Now let's talk about India. The digitalization of postpress technology is currently mainly indentation and die cutting. This technology is mainly used for the post-press processing of personalized packaging, publishing, and non-standard containers in small batches. The greatest feature of digital postpress processing is randomness and freedom. Degree, the process completely eliminates the need for the original indentation, die cutting die, this type of equipment is the production of personalized packaging essential.
