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

I looked at the website related to printing equipments, they have many choices but I still need to discuss more about what do we need exactly.
