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 ...
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 ...
Screen printing is far and away more than t-shirts- and it can be a lot less complex. The Cut Stencil technique is very easy to do and amazingly capable for the beginning screen printer. At it's heart, the screen in a print process is a way to meter ink and allow the ink to be placed on an object in a controlled fashion. The printable image is commonly adhered to the screen, but it doesn't need to be. The stencil project consists of an image cut out of an acetate sheet and simply taped to the back of the screen. Clear acetate or plastic sheets used for transparencies work great here! The sheet needs to be about the grade of an x-ray image, slightly stiff but not so thick that it can't be cut accurately with a sharp x-acto knife. Plastic is required so the stencil is ink and water proof. the reasoning behind this is so the stencil will not degrade during a print run or subsequnt clean up. In this example, the floral se...
