Notes from screen printing testout session 23.06.09:

  • Material bought from Wöco:
    • FIXME
  • Sensitize emulsion:
    • Fill up the small sensitizer bottle with water
    • Add to the box with emulsion
    • Stir well
  • Coat screen with emulsion
    • Do this away from bright light or sunlight
    • Use the "squeegee" to coat the screen with emulsion
    • Do this from both sides repeatedly to get an even coverage and an even surface as a result
  • Dry the coated screen (this will taka 30-60 minutes)
    • Place horizontally in a _dark_ room
    • To speed up, use a fan (occationally using a hairdryer might also help)
  • Prepare the design
    • Design a positive 1-color bitmap image (i.e. what you see is where the ink goes)
    • Print on a transparent foil using as dense ink as possible
    • Our printout was not very dense due to a broken/out-of-ink printer
  • Expose the screen
    • Place the printed transparent foil onto the screen
