“55” means the thread diameter is 55 microns
“135 mesh” means there are 135 holes per inch
For “T”, there are 3 kinds: S, T, HD
“S” : A thinner thread diameter, so more ink is applied to the substrate. Ideal for opaque printing to textiles, for example 53S-48(135mesh). ”T” : Standard mesh thread diameter, used for most printing jobs, for example 53T-55(135mesh).
“HD” : Heavy duty mesh thread diameter, used for where the mesh may be subject to excessive wear from sharp objects or abrasive ink, for example 53T-70(135mesh)
