Screen printing is a common printing technique that uses a screen to transfer ink or pigments onto printed materials to form patterns or text. This printing method is also known as silk screen printing, and it has a wide range of applications, including textiles, electronic products, plastic products, painting art and advertising.
This article introduces the production process, types and benefits of screen printing in detail.
The basic process of screen printing is as follows:
1. Make the plate
Make the pattern to be printed on one or more screens, usually using polyester fiber, nylon or stainless steel screens.
2. Make a printing template
Paste the plate on the aluminum frame to form a printing template.
3. Prepare the ink
Choose the appropriate ink according to the printing requirements, and adjust the color and density of the ink.
4. Ink rubbing
Apply the ink on the screen and scrape it evenly with a scraper.
5. Embossing
Place the printing template on top of the object to be printed, and imprint the ink onto the object through the screen.
6. Drying
After the ink is dry, the printed pattern is completed.
Types of screen printing:
According to different application fields and requirements, screen printing can be divided into various types, including the following:
1. Flat screen printing
Make a screen mold on a flat plate, and then transfer the ink to the printing material through the opening part of the screen.
2. Rotary screen printing
The cylindrical screen mold is fixed on the printing machine, and the ink is transferred to the printing material by rotating the screen mold.
3. Elastic plate printing
Using a screen mold made of elastic material, it can better adapt to irregular surfaces during printing and improve printing quality.
4. Thermal transfer screen printing
By transferring thermal ink to thermal paper, and then contacting the paper with the printing material, the ink is transferred to the printing material by heat pressure.
5. High-viscosity screen printing
Use high-viscosity ink, suitable for printing rough surface materials such as wood or plastic.
6. Steel screen printing
The mold made of steel plate can be used for efficient and long-lasting printing on a large printing area.
The benefits of screen printing include:
1. Wide range of applications
It can be applied to the printing of flat, curved and three-dimensional objects.
2. Rich colors
There are many kinds of inks, and various colors can be prepared.
3. Rich texture
Rich texture, gloss and texture effects can be achieved.
4. Strong durability
The screen printing pattern is durable, wear-resistant and not easy to change color.
5. High production efficiency
It can realize large-area continuous printing and is suitable for mass production.
6. Easy operation and maintenance
Screen printing equipment is easy to use, easy to maintain and clean.
Summarize
Screen printing is a widely used printing method with a simple process and a wide range of applications. Its advantages include good adhesion, vivid color effects and the ability to adapt to various shapes and surfaces. Whether for commercial printing or artwork production, screen printing is an important technology.
