What is mesh count?
Mesh count refers to the actual count of threads per square inch/cm (in both directions). It affects ink deposit, images, and print quality.
Typically, for spot design prints, you can use as low as 25 mesh up to 300 mesh count or more depending on the type of inks that you can use and the line thickness and font size that you use.
For halftone prints, it is dependent on the dot size (LPI) of your design. The lower the LPI, the lower the mesh count. The higher the LPI, the higher the mesh count. It is also dependent on the type of ink that you will use. Water-based inks, with proper printing technique, can work well up to the minimum of 150-180 mesh. Plastisol inks can work well up to 355 mesh.
