Introduction

When analyzing the term "printed electronics," it can be simply understood as an industry involving the use of a certain printing technology to manufacture electronic devices and products.

For centuries, printing methods have been widely used on substrates such as textiles and paper. In the past, the advent of mass-producible printed materials...

The methods of storing, transmitting, and replicating knowledge have had a profound impact. At the current stage of technological development, printing on rigid or flexible substrates...

It is considered a complement to or alternative to traditional electronics manufacturing processes. The difference between media printing and printed electronics lies in the fact that media printing is used for transmission...

Printed electronics transmit information for humans to read and process with their eyes, while printed electronics require machines to recognize and process electronic information; the required resolution levels and functions...

Sex is the reason for the difference between the two. Some functional materials widely used in printed electronics include, but are not limited to, nano- or micron-sized materials.

Metal particles, semiconductor polymers, and dielectric materials. Due to the need to achieve a certain recognition resolution, it is necessary to print particles smaller than 20 µm.

The tiny feature sizes. The thickness of the printed film layer is closely related to the quality control of electronic devices, and the registration accuracy and ink materials both need to reach a certain level.

A very high level of quality. Overall, the precision tolerances in printed electronics are much smaller.

Printed electronics printing processes are mainly divided into two categories. One category is non-contact printing processes, such as inkjet printing and electrostatic dispensing (ESD).

Printing processes; another type is contact printing processes, such as gravure printing, gravure offset printing, reverse offset printing, and screen printing. This document mentions...

It provides recommendations for measuring and evaluating printing plates, therefore its scope is limited to printing processes that use printing plates. GB/T 47251 is proposed to consist of 3...

Terminology and methods.

Because the ink is transferred directly from the printing plate to the substrate, the printing quality of the circuitry depends on the quality of the printing plate. Therefore, the quality of the printing plate is crucial.

Quantity is very important. Many companies are involved in the large-scale production of printed electronic equipment, including equipment manufacturers, plate manufacturers, and printing press manufacturers.

Plate manufacturing equipment suppliers all involve standardized measurement and evaluation methods for using printing plates.

3 Terms and Definitions

The following terms and definitions apply to this document.

platemaster

A medium for transmitting printed text and images.

Note. The image on the printing plate can be raised above the surface (relief printing) or engraved below the surface (intaglio printing).

The definitions required to determine the shape and size of the printing plate.

Orientation Corner

Asymmetrical angles are specified for mechanical positioning and for operator visual confirmation of the printing plate orientation.

Note. This term is illustrated graphically, as shown in Figure 1.
