As it works out, 95 percent of screen printing work is about cleaning stuff up. That a lot of products are water clean up is helpful. Here are some tips on getting your expensive screens ready for another project. The hardest part about screen reclamation is letting go of your work. Cleaning out screens after using the drawing fluid and screen filler process usually takes just a few minutes. Get a good place to spray a lot of water. A sharp angle hose nozzle, or better yet, a power washer will make short work screen reclamation. Usually there is a chemical of some sort to help things along, things are no different here. In this case spray Strip-e-Doo on the screen and let is work for a few minutes. Then have at it with the sprayer nozzle. Screen filler is tough stuff and usually takes some effort with a sprayer and a scrub brush to clear the screen. When putting screen filler on a screen, try to apply just enough to full the ...
The Exposure Table- At the heart of screen printing is the creation of the screen. One of the earlier techniques, drawing fluid and filler, featured artwork created directly on the surface of the screen . When the printing is complete, the artwork is removed from the screen and lost during screen reclamation. Exposing a master image to a photosensitive emulsion on a screen allows the reclamation of screens without loss of the artwork. Now the screens are simply tools of the craft rather than artwork originals. Exposure tables are a nice tool to have although screens can certainly be "burned" using halogen shop lights and a watch. Screens can even be exposed using the sun! At it's core, an exposure table consists of a bright, non-point light source and a way to hold the artwork master tightly to the emulsion on the screen. A tight fit reduces light bleed and allows detail to be transferred to the emulsion. Several types of masters can ...
Media Location & Registration for Printing- In order to print multiple colors precisely, some method of accurately placing media must be employed. Two techniques outlined here are taped corner registration and pin registration. With some work there is no need for super accurate registration. For example, with the Drawing ink and Filler example the registration used was very loose so taped corners did quite well. With a process color (CMYK) print registration is imperative. Since colors are "mixed" in the eye, a small bit of misalignment between screens / colors causes large changes in the final look. Taped Corners- Taped corner registration is quick and cheap. It consists of, you guessed it, tape markers on diagonal corners of the print media. Using this system does take a little extra attention in placing each new sheet of paper but beyond that, it's an effective method. With the work surface prepare...
