Satin weave

For satin/atlas weave, the weft passes under one warp thread and then over the next two or more. The adjacent weft thread follows the same pattern but staggered by at least two warp threads. In this way a fabric is made in which parallel weft threads predominate on the top surface and warp threads are thus mostly exposed on the bottom surface.
This results in a particularly smooth surface.

Sawtoothing

The edges of printed lines and areas are spiky. Main reason: coating thickness too small, and/or RZ value too high

Screen printing frame

Aluminium and steel are the mostly used materials for screen printing frames. Aluminium frames are less heavy and easier to handle but to give a comparable strength to steel , the cross sectional area must be enlarged. See also 'frame'
