Description of weave type
Plain weave 1:1 = PW
The mesh type is specified along with the weave type. This describes the pattern in which the weft and warp fibres cross over each other, and is expressed as a weave number.Screen printing mesh are either plain or twill weave. Plain weave is a 1:1 weave.
Twill weave 2:1 = TW
Various types of twill weave have differing weave numbers e.g. 1:2 or 2:2.
Do not use twill weave meshes for half-tone prints! They often lead to line pattern in a 45° angle according to the weaving structure! (see Moiré effect)
