The stated values are in [N/cm] according to DIN 16611 (screen printing
standard) and measured using
SEFAR® Tensocheck 100. The above
values refer to tensions measured after
stretching only (before gluing to the
frame). These values are valid for
dimensions of 1x1m. Larger formats will
show a reduction of approx 4% every
0,5 m of additional shank length.
Tensioning system requirements
In view to obtain the above values, the
performance of your tensioning system
should be:
–Stretching clamps SEFAR® 2,
SEFAR® 3A or any other system that
guarantees even and balanced tension.
–A mesh clamping system that does
not allow the mesh to slip, even under
high tensions. It should be regularly
cleaned and exempted of contaminants such as oil and dirt.
–Tensioning clamps should be regularly
checked in view to avoid sharp edges
which could damage the mesh.
–High humidity and high temperature
could have influences on stretching
performances. This may lead to difficulties during the stretching process.

Stretching process / Relaxation:
Loss of tension after gluing process
Tensioning process lasts up to 3 minutes
until the desirable tension is achieved.
Waiting time approx 3 to 5 minutes
before gluing the mesh on the frame,
the loss of tension after 24 hours will be
10 to 20% for respectively, coarse and
fine meshes (any other parameters such
as frame deformation are not taken in
account).
Other causes of loss of tension:
–Poor frame characteristics (profile,
material…)
–Not adequate frame pre-tension
–Quality of the adhesive
–High humidity
