More information about screen printing mesh size: Different mesh sizes are used for different
applications in the screen printing process. Mesh size is measured by how many

inks. These inks contain particles that will not pass through typical
mesh sizes. So you need a lower mesh number with large holes to
all particles pass correctly. Glossy plastisol inks have finer particles so you could probably use 86 mesh, while glossy inks have much larger particles so 40 or 60 mesh is recommended. 200 and 230 mesh are used for more detailed images and finer inks. These mesh sizes can contain larger halftone dots, but are not
Recommended for four color process prints or fine detail halftone printing.
Solvent-based and graphic screen printing inks that are much finer should also be used with these mesh sizes. Also, if you want a softer ink feel on your shirts, you can

printing on signs, banners or CD. The use of a higher mesh allows automatic
printers used in UV printing to regulate the amount of ink that passes through the
screen.
