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

Other causes of loss of tension:<br />
– Poor frame characteristics (profile,<br />

– Not adequate frame pre-tension<br />
– Quality of the adhesive<br />
– High humidity<br />
