Everything You Need to Know About Screen Printing Mesh
What is Screen Printing Mesh?
It is a finely woven fabric that serves as a stencil in the screen printing process, used for transferring ink onto different surfaces like fabric, paper, glass, and metal. It allows ink to pass through open areas while preventing it from reaching parts of the surface not meant for printing. The mesh is stretched tightly over a frame, and the mesh count and material type influence the quantity of ink applied and the precision of the printed details.

What is Screen Printing Mesh Count?
Mesh count refers to the number of threads per inch in a printing mesh. This measurement is crucial as it directly impacts the resolution, ink deposition, and the level of detail achievable in the printing process.
Higher mesh counts mean finer threads and smaller openings, which are great for detailed designs and thin ink layers. Conversely, lower mesh counts have larger openings, suitable for thicker inks and bolder graphics.
Common Types of Mesh Count and Their Applications
Mesh Count | Description | Common Applications |
32T | Low mesh count, allows for more ink deposition, ideal for bold designs. | Specialty inks like glitter or flakes. |
43T | Low mesh count, good for heavy ink deposits. | Textile printing with excellent coverage. |
55T | Low mesh count, balances coverage and definition. | Textile printing and general applications. |
64T | Medium mesh count, suitable for various materials. | Printing on textiles, paper, and cardboard. |
77T | Medium mesh count, good for finer details. | Lightweight garments and paper printing. |
90T | Commonly used for higher detail designs. | Top layer prints on fabric and paper. |
110T | Versatile mesh count, suitable for bold designs. | T-shirt printing and general-purpose screen printing. |
156T | Medium mesh count, balances detail and ink coverage. | Textile printing with moderate detail and bold colors. |
230T | High mesh count, ideal for fine details and thin inks. | High-resolution prints on lighter fabrics and paper. |
305T | Very high mesh count, allows for intricate designs. | Detailed artwork and halftones on smooth surfaces. |
Impact of Mesh Count on Printing
The mesh count in screen printing plays a critical role in determining the quality and characteristics of the final print. Essentially, it affects three major aspects of printing: resolution, ink deposition, and the texture of the print.
- Resolution: A higher mesh count, with more threads per inch, results in a finer mesh. This allows for printing finer details because it can hold smaller dots of ink. It is ideal for intricate designs or small text that requires high precision.
- Ink Deposition: The amount of ink that passes through the mesh to the substrate varies with the mesh count. Lower mesh counts have larger openings, which permit a greater volume of ink to pass through, creating a denser and more opaque print. This is particularly beneficial for bold designs or when using specialty inks like metallic or glitter.
- Texture of the Print: The texture of the final print can also be influenced by the mesh count. Coarser mesh (lower mesh count) generally results in a thicker ink layer, which can add a noticeable texture to the print. Conversely, higher mesh counts lay down a thinner ink layer, which can be smoother to the touch.
These factors collectively contribute to the versatility of mesh printing screen techniques, allowing for customization according to the specific needs of the print job, from detailed artistic images to robust commercial designs.

Considerations for Selecting Screen Printing Mesh
When choosing the right mesh for screen printing, several factors need to be evaluated to ensure optimal print quality and efficiency.
Material Type
The material of the mesh can influence its durability, ink compatibility, and print quality. Common materials include polyester, nylon, and stainless steel, each offering different benefits depending on the printing application.
Mesh Count
Selecting the appropriate mesh count is crucial as it affects the resolution and the amount of ink deposited. Higher mesh counts are used for detailed prints on smooth surfaces, while lower counts are better for bold prints on rough surfaces.
Thread Diameter
The diameter of the threads in the mesh can affect the overall ink deposit and the detail of the print. Finer threads provide detailed prints with less ink deposit, suitable for high-detail designs.
Mesh Tension
Proper mesh tension is essential to avoid issues like blurry prints or uneven ink distribution. Higher tension typically results in better print quality.
Mesh Color
Mesh color can impact the exposure times during the screen making process and ultimately affect the print. White mesh offers lower exposure times, suitable for finer details, whereas yellow or orange mesh helps with sharper images and is better for very fine detailed work.
Maintenance and Cleaning Tips for Screen Printing Mesh
To preserve the quality and extend the life of your printing mesh, proper care and cleaning are essential. Here are some straightforward guidelines to follow:
- Regular Cleaning: Clean the mesh promptly after each use to prevent ink from drying and clogging the mesh openings.
