what is ruby lithe? and how and why is it used from your plotter ? thanx trying to reaquaint myself w/screenprinting
Posted by Dave Johnson (Member # 2535) on :
Rubylith is a cuttable film that blocks out light from exposing portions of your screen. The idea here is that you cut a positive image (the screen has to be a negative to print a positive) and weed out the portions that you don't want to print.
When exposed to light the emulsion, direct or indirect film will cure or set. The ruby prevents the image area from curing and that portion will wash out with water or solvent depending on the system you are using.

Another option for you is to skip the Rubylith and use UlanoCut Green (or Amber). It is a water-adhered, water soluable stencil film. You cut it on the plotter and reverse weed. No need for photostencils.
