What is silkscreen printing?
In the simplest way, silkscreen printing is a printing technique that uses printing molds. This mold is used to position the printed image and then has a lever to spread the ink evenly on the surface through the printing mesh.

The reason it’s called silkscreen printing is because when they first applied this printing technique, professional craftsmen used silk to separate the ink and the material to be printed. In the following years, people gradually replaced them with other materials such as fabric, cotton, metal mesh, etc. However, the name silkscreen printing remained for this printing technique.
The development history of screen printing
Screen printing was invented a very long time ago, more than 1000 years ago people discovered a way to duplicate images on materials by stretching fabric fibers on wooden frames. Next in France and Germany in the 1870s, researchers invented the use of silk fabrics to make printing nets. Helps make copies to other surfaces quickly and synchronously.
Next, in 1907, Samuel Simon invented the process of making nets with silk threads.
In 1914 John Pilsworth developed the multi-color screen printing method and was first applied in San Francisco, California. Mark the development milestone to this day.
Classification of silkscreen printing techniques
In printing silkscreen printing techniques will be divided into many different types. To make it easier for everyone to visualize, we will detail each of these classification criteria.
Based on the way the mold is printed
The first will be based on the printing mold, people will divide silkscreen printing into 3 types:
Handmade silkscreen printing
Handmade silkscreen printing will be done 100% manually from ink wiping to drying. This printing method is usually only used to print small orders.
Semi-automatic silkscreen printing
Semi-automatic screen printing, also known as screen printing, mechanizes a few operations. It still has to be done manually, but the alignment will use some extra printing done by the machine. Helps increase work efficiency and reduce execution time.
Automatic silkscreen printing
As the name suggests, automatic screen printing is the use of machines. Alignment, ink removal, and drying are all done by the machine, helping to increase the amount of printing in a short time.
Based on the shape of the printing mold
In addition to the way the mold is printed, people also divide the technique silkscreen printing according to the shape of the printing mold. According to this division, there are flat mesh molds and round molds.
Flat screen printing mold
Flat screen printing molds are sheets and are often used to print on soft and flat materials such as: Fabric, paper, rubber, etc.
Silkscreen printing using a circular mesh printing mold
Circular mesh printing molds are often used to print on curved materials such as: Printing on dishes, ceramics, printing on glass, etc.
Based on printing method
Finally, based on the printing method, based on this criterion, screen printing will also be divided into 3 types:
Direct silk printing
This is a way of printing directly on the product to be printed, usually this style is usually applied to yellow or white printed materials. Because these finished products will not be affected by the background color, the print quality is sharper.
Break-through silkscreen printing
Next is silkscreen printing This printing technique is often applied to items with background color, if printed directly, the color will be blurred. Therefore, people will use breaking screen printing technique to print the desired color on the finished product without smudging or smearing.
Backup silkscreen printing
If the printed materials have a background color, but the back-up printing cannot be used, the backup printing method will be switched.
Principle of silkscreen printing
Principle of silkscreen printing technique very simple, similar to the principle of printing oil ink on paper. In silkscreen printing, people will use silk molds or metal mesh molds, then ink on it. Only a part of the ink penetrates through the printing mold to go down to form the shape on the material to be printed.
Advantages and disadvantages of silkscreen printing
Each type of printing has its own advantages and disadvantages. So when choosing to use, everyone should grasp these advantages and disadvantages to decide whether to choose silkscreen printing or other printing techniques.
Silk screen printing possesses many advantages, so this technique has been applied for a long time and is still widely applied. So what are those advantages?
- Low printing costs because there is no need to invest too many modern machines to serve the printing process.
- Can print on many different materials such as: cloth, paper, plastic, glass, ceramic, rubber, …. Sharp image quality.
- You can print as many colors as you want.
Besides the advantages silkscreen printing technique There are also many disadvantages as follows:
- Each printing color and image will use a different mold, so it is very time consuming, moreover, printing a small quantity will cost a lot of money if printing in many colors.
- It is easy to break the printed image during or after printing, if the ink is not good.
- The ink adheres quite tightly to the material, so it is difficult to wash and remove. Therefore, when implementing requires care to avoid ink smearing outside.
- Each printing will need a screen printed film board, so a vector file and design file are required. The image files will not be usable, requiring the worker to design to the above two file types. So it takes quite a while to execute.
- Screen printing is very difficult to print discolored or orange shapes. Therefore, most of the printing of silkscreen printing is color printing.
- Silk-screen printing usually takes longer and more stages, so it cannot be taken immediately like digital printing. Moreover, it is only suitable for small and moderate quantity orders.
What elements are required for screen printing?
To get a publication silkscreen printing perfect, one will need to prepare all the elements, complete tools. Specifically as:
Materials to be printed
The first will be the materials that need to be printed, printed information on it. These materials include: fabric, paper, rubber, glass, leather materials, metal, etc.
The printing mold is usually made of a square or rectangular wooden frame that fixes the printing net. The printing mold is also a place to store the ink and let the ink pass through the mesh to penetrate the surface of the material.
Printed mesh part
Say silkscreen printing But this printed mesh is quite diverse, can be silk fabric, cotton fabric, cotton fabric or metal mesh. The printed grid will be divided into a printed quarter and a non-printed element.
Screen printing inks are very different from those of other printing techniques. They are pliable and viscous. Usually will be produced in each color and in a separate box. If you want to create another color, the worker will have to mix it yourself when doing it.
The lever will depend on the printing mold to design the size, usually made of wood. The bottom of the lever will have to be flat so that when pulled on the mesh surface, a uniform print will be created on the surface of the material.
Finally, the printing table is a tool to place and fix the material to be printed. Normally, people will use a special glue layer to keep the material to be printed from moving, to help the printing process not be skewed or smeared.
Silk-screen printing process
Want to create a publication with silkscreen printingone will have to go through 5 stages, the printing process is as follows:
Step 1: Prepare the frame and make the glue
First, the craftsman will prepare a printing frame, this frame is usually made of wood and has a rectangular shape. After that, it will continue to mix PVA glue, the glue needs to have a certain consistency to achieve high efficiency when covering the surface of the printed mesh.
Step 2: Take a film and make a printing mold
In this step, people will use the previously mixed glue to cover the surface of the printed screen and then dry it. Next, film will be taken on the printed screen by placing the film board on the glue layer of the mold and photographed under the sun or under a white light.

Filming after 2-3 minutes, the printer will take out the printing mold and spray it with water. So at the locations where the film has just been taken, the glue layer will be washed away and the ink will easily penetrate through it to print on the printed surface. For each color, people will use a different film board and do it in many prints.
Step 3: Mix ink
This step will apply to colored prints. Here, the worker will use the basic printing colors to blend to create the right ink color with the image to be printed.
Step 4: Proceed to print
To proceed with printing, people will fix the material to be printed on the printing table with a special glue → Put the mold in place → Put the ink on and pull the lever to let the ink penetrate the printing mesh → Repeat at least is 2 times for the ink to adhere evenly to the surface.
Step 5: Dry or dry the finished product
Finally, after getting the finished product printed on the surface, the printer will proceed to dry or expose the finished product. Drying or drying for 12 – 48 hours for the printed image to dry and adhere to the surface of the material. Then move on to another stage.
