AWT Mesh Thread Count And Halftone Determiner Tool.
An Invaluable
tool for determining the mesh threads per inch and also
halftone counts. Place you screen on a light table and the
thinly spaced lines cause a moiré pattern that point
to the mesh count. Moiré will display for 300 mesh
as a pattern at 150 and 100.
Stop guessing which mesh count in on your frame. Easy to read both U.S. and
metric mesh numbers of monofilament and multifilament fabric, either from roll
or stretched on frame. Two different scales are used for monofilament meshes,
one for USA mesh counts from 100 to 240, and metric counts from 40 to 95; the
other for those USA counts from 200 to 480, and metric counts from 78 to 190.
Multifilament chart determines mesh counts from 6XX to 25XX, USA halftone counts
from 55 to 200 and metric halftone numbers from 21 to 78. Photographically
produced on heavy 8 x 10" polyester photo film ( 7 mil. ) for durability and
clarity.
Note: This is not a tool to help you with the proper mesh count selection for screen making.
