How to Screen Print:
This dude explains it all in 15 min!
PREP:
- Coat screen in photo emulsion in a red light room
- Wait for screen to dry (use drying cabinet to accelerate, if available).
- Print out a positive, transparency film with design on it
- Lay positive onto UV exposure unit with dried unexposed screen,.
- Expose.
- Wash out unhardened photo emulsion with warm water from an electric power shower (mildly pressured) in front of a waterproof light box
- Dry again in another drying cabinet or wait for it to dry naturally
- Use brown tape to block out any unwanted areas of the screen that are not coated with photo emulsion
- Mount screen into frame
- Put a bead of ink along one edge, and float the screen
- Use newsprint to do a test to get it going
- Use a piece of plastic fixed to the bed to find the position of the print on the bed for alignment with the paper
- Use masking tape to mark corners
REPEAT:
a. Locate paper on masking tape registration corners
b. Drop the screen onto the bed
c. Pull once/twice hard towards you
d. Lift screen
e. Flood back the screen to prevent drying
f. Place paper in drying rack
WRAP UP:
- Wash screen with pressure washer to blast out all the ink and photo emulsion
- Dry screen ready for reuse.
NOTE:
- If the screen starts to dry you can have Mr Muscle on hand to keep the screen moist (not sure why this and now something else)
- Don’t let the screen dry with ink in it, or the holes in an air suction table.
- The process for t-shirts requires a heat curing thingy and paper and ideally a t-shirt shaped bed for alignment and hold down.
