Hi Haitham,
 
  I looked into screen printing equipment and found a manufacture by the name of M&R Printing,
 
  if you go on the internet and type that in you can look to see if they have something that would fit.
 
Other than that I know some people have used equipment.  With regards to the SW100 we have a material that is the same which is    
 
  our Additive T.  If you need a pint of that testing let me know.
 
Hope this helps
