Screen Printing Overview - Murakami Screen

Screens
• Stretcher with several screens being
stretched on the bias to prevent
moire. Easier and less costly to
change angle of halftone during
output of films.
• Typical tension on a 300T would be
to perform a rapid stretch technique.
• The mesh is brought up to ever
increasing tension four times.
• First 15 newtons, Second 19
newtons, Third 22 newtons, Fourth
25-27 newtons, then allow to sit for
five minutes or longer.
• This will result in the highest
retained tension after being cut out,
about 22 newtons after cutting.
• After the initial print run tension will
drop to about 17-19 newtons. Only
a high quality mesh will retain that
tension. Cheap mesh will continue
to lose tension with every print run.
