What are the modern printing technology methods?

With the rapid development of printing technologies, especially since the introduction of digital printing, the author of this article has summarized the printing techniques currently in use in the market, classified them, and analyzed their working principles. By comparing these various printing techniques, it is possible to identify the advantages and disadvantages of each one, so as to select those that meet our needs. I. Spray Printing: The detailed requirements regarding file preparation when creating designs are as follows: 1. For large-scale outdoor spray printing, the files should be in proportion to the actual size, with a resolution of 32 pixels per inch. The color mode can be CMYK or RGB, depending on the requirements of the printing machine; some machines have poor handling of black colors, so it’s necessary to use Photoshop to remove black elements from the design files. 2. For indoor photo printing, the files also need to be in proportion to the actual size, with a resolution of 72 pixels per inch. The color mode is usually RGB. It may also be necessary to apply a laminating film over the printed material.

II. Ink Printing: According to our design requirements, the file size should be in proportion to the actual size, with a pixel resolution of 300 pixels per inch. The color setting for printing is standard CMYK. After the design is finalized, it is sent to a graphic output service center where it is converted into film suitable for printing. This film is then taken to a printing factory to create a printing plate. Finally, the printing is carried out using the machine. If the customer has special requirements, such as for packaging materials, it’s necessary to create separate die-cutting files, convert them into film, and send them to a die-cutting factory. There, the die-cutting specialists will turn these files into die-cutting plates. Once the printed products are ready, the die-cutting plates are attached to the machine, and the products are cut out one by one manually. This process is referred to as “die-cutting.” If the printed products need to be laminated, this step must be carried out before printing. There are two types of laminating films: glossy and matte. This constitutes the entire process of ink printing.

III. Alcohol Printing: The process of alcohol printing is simple – all that’s needed is a computer, paper, and an alcohol printing device. Its principle is quite straightforward: it combines traditional printing technology (ink printing) within one machine. The computer sends the data to the printer, allowing the printing process to be completed in one go. This can also be called digital printing. However, tasks such as die-cutting, laminating, and punching still require manual intervention. Due to the high cost of these devices, this printing technology has not yet entered the mainstream market; only a few printing factories possess such equipment.

IV. Screen Printing: The process involves several steps: creating film, developing the plate, setting up the printing frame (usually made of aluminum), and then carrying out the printing, either mechanically or manually. This type of printing equipment is generally relatively inexpensive. Usually, only one color is printed at a time; for multiple colors, color separation is required, which increases the cost. One of the outstanding advantages is that the ink can be printed in a thicker layer, resulting in a richer texture and stronger adhesion. 5. Rapid printing: In terms of its working principle, generally speaking, it is a large-scale printing unit capable of printing on coated paper; its structure consists mainly of a computer server connected to this device. It is also known as a digital proofing machine. This printing technology is often used for small-scale printing, such as preliminary proofing of printed materials. Traditional proofing methods were similar to the actual printing process, but the advent of this machine has replaced those old methods, which were both complicated and costly. It is also used for producing brochures, small books, and color pages for project proposals. The above is a summary by the editor of the different categories of modern printing processes, along with a brief analysis of them. It is hoped that this information will be helpful for everyone learning about printing processes. This article is reproduced from: http://www.vsprint.net/news/1703.shtml
