Screen Print & Using The Registration Guides
The function of Pin Bar registration system in use with screen printing is slightly different than that used with lithography. The Pin bar is used here to make the registering of the paper easier an faster and to help cut down on multiple choices of registration.
Step to using the Pin Bar registration system in screen printing:
- Place the screen in a set of locked hinges
- Place a piece of clear mylar down under the screen. – Make sure it is big enough to cove the image and still be able to be taped down so it will not move.
- Place ink in the screen and do a pull over the image printing on to the mylar.
- With your punched paper on the pin bar slide the paper under the printed mylar an establish where you want the printed image to print.
- When you have determined the right spot TAPE THE PIN BAR down into postion.
- Take up the mylar and place a new sheet of paper on the pins and make a pull
- Continue placing the paper on the pins and making pulls till you have exhausted your paper selection.
