Printing Press Structure and Principle
A printing press is a device specifically used for printing images and text. It typically consists of upper and lower platens, a roller, an ink roller, ink or water cartridges, transmission components, and an electrical control system. It works by transferring ink or water through pressure between the printing plate and the paper to print designs and text onto paper or other materials.
Why a printing press can't make copies?
During the printing process, printing plates undergo complex processes such as typesetting and platemaking, resulting in complex graphic designs. Therefore, large-scale printing is often required. A photocopier, on the other hand, is a device specifically designed for copying documents, books, and other documents. It is simple to operate and easy to use, and can be used for small batches or single-sheet reproduction.
Although both printing presses and photocopiers are digital printing devices, their principles and functions differ, making them incompatible. Printing presses are designed for precision and speed, while photocopiers prioritize fidelity and ease of reproduction.
New Technologies in the Digital Printing Era
With the rapid development of digital printing technology, digital printing equipment has become versatile. Certain models of printing presses now include copying capabilities and can handle multiple printing methods, such as single-sided printing, double-sided printing, embossing, laminating, and more. These devices are often used in offices, designer studios, and other settings where flexibility is crucial.
