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
