Screen Printing

Transcript: Select a screen that suits the size of your image. In a dark room under low light, apply a coat of emulsion to each side of the screen and allow to dry overnight in complete darkness. Tape your image (the one printed on posi paper) face down onto the print side and place screen print side down in the exposing unit. Make sure to place the string diagonally across the screen and seal completely. Once you are done this, turn on the blower first then the vacuum. Once all the air is removed and the cover is tight around the screen, turn the light on and set time for about 7 minutes. Scrape off the excess ink with a spatula and return it to the pail. Make sure that the spatula is free of ink. Scrub with brush, then using the water gun rinse all the ink and clean up. Next, take the stencil remover in the pump and spray the entire screen front and back. Allow to sit, and then using the power gun, remove emulsion. Then set to dry. Step One Seven Step Five wipe off the acess water from the screen. Then bring the screen to the printing press and fasten the screen down using the appropriate clamp. Select a substrate and place onto the printing board, and be sure to use the web spray to hold it in place firmly. If another stroke is not needed, lift up the screen and place the dryer over top of your completed image. Leave for 30 seconds, watching carefully because there is a chance of burning. When the 20 seconds are up, remove the dryer and carefully check to see if the ink is still wet. If it is, put the dryer back on and if not, then remove and turn off the dryer. The first step of screen printing is choosing your image, and then printing it off on pozi paper. Step 9 Step 8 Screen Printing By: Jessica Krmpotich First turn on the dryer to 350 degrees celsius, then choose your colour of ink. Test its viscosity and add a small amount of ink thinner if too thick. Then using a spatula, place your desired amount of ink above the burned out image area. While your screen is still raised, use a squeegee and make a "flood stroke". This will prevent ink from drying in the screen. Once this is completed lower the screen and make another stoke across the image, pressing firmly, to transfer the ink onto the substrate. Lift the screen to examine your image, to see if another stroke is needed. If so continue with another. Step Four After your 7 minutes is up, remove the screen from the exposing unit. Remove the posi-paper and take the screen to the washing station. Using just water at low pressure, carefully remove all the burnt out image area. TIP: You know your image is done when the image area is clear of any emulsion. Step Three Step 6 Step Two Once your screens are clean there is one last step; screen preparation. Meaning you remove any grease left on the screen and then rinsing thouroughly.

Transcript: Andy Warhol, Rob Ryan, Blexbolex, Arthur Okamura, Robert Rauschenberg, Harry Gottlieb, and many other artists have used screen printing as an expression of creativity and artistic vision SCREEN PRINTING Caviar beads Cracking ink Discharge inks Expanding ink (puff) Flocking Glitter/Shimmer Gloss Metallic Mirrored silver Nylobond Plastisol PVC and Phthalate Free Suede Ink Screen Printing Material Screen printing was first patented in England by Samuel Simon in 1907.[2][3] It was originally used as a popular method to print expensive wall paper, printed on linen, silk, and other fine fabrics. Western screen printers developed reclusive, defensive and exclusionary business policies intended to keep secret their workshops' knowledge and techniques.[4] There are several ways to create a stencil for screenprinting 1.The original image is created on a transparent overlay such as acetate or tracing paper. The image may be drawn or painted directly on the overlay, photocopied, or printed with an inkjet or laser printer, as long as the areas to be inked are opaque. A black-and-white positive may also be used (projected on to the screen). However, unlike traditional platemaking, these screens are normally exposed by using film positives. 2.A screen must then be selected. There are several different mesh counts that can be used depending on the detail of the design being printed. Once a screen is selected, the screen must be coated with emulsion and left to dry in the dark. Once dry, the screen is ready to be burned/exposed. 3.The overlay is placed over the emulsion-coated screen, and then exposed with a light source containing ultraviolet light in the 350-420 nanometer spectrum. The UV light Screen printing is a printing technique that uses a woven mesh to support an ink-blocking stencil. The attached stencil forms open areas of mesh that transfer ink or other printable materials which can be pressed through the mesh as a sharp-edged image onto a substrate. A roller or squeegee is moved across the screen stencil, forcing or pumping ink past the threads of the woven mesh in the open areas Thank you for your attention!

Transcript: Screen Printing Amy Maniacco November 17, 2011 TGJ3M1 Screen printing is a printing technique that uses a woven mesh to support an ink-blocking stencil It can be used to print on a wide variety of substrates, including paper, paperboard, plastics, glass, metals, fabrics, and many other materials. including paper, plastics, glass, metals, nylon and cotton. Screen printing is the most versitile of all printing processes The advantage of screenprinting over other print processes is that the press can print on substrates of any shape, thickness and size. Theses are the steps to screen printing. Step 1. Print your atrwork onto posi-paper supplied by your teacher. Step 2. Select a screen that suits the size of your image. In a darkroom under low light, apply a coat of emulsion to each side of the screen and allow to dry overnight in complete darkness. This step is done by the teacher ahead of time. Step 3. Tape your image (the printed one) face down onto the print side and place screen print side down in the exposing unit. Make sure to place the string diagonally across the screen and seal completely. Once done this, turn on the blower first, then the vacuum. Once all the air is removed and the cover is tight around the screen, turn light on and set for 6:30 minutes. Step 4. Expose screen for 6:30 minutes, remove the screen from the exposing unit. Remove the posi-paper and take the screen to the washing station. Using water at low pressure, carefully remove the burned out image area. Tip: you'll know it's done when the image are is completely clear of any emulsion. Step 5. When screen is dry after developing, bring the screen printing press and fasten the screen down in the appropriate clamp. Select a substrate and place it onto the printing board. Be sure to use the stick spray to hold the substrate firmly in place. Step 6: Choose a colour of ink. Test its viscosity and add a small amount of ink thinner if it's too thick. Then, using the spatula, place the desired amount of ink above the burned out image area. While the screen is still raised, use the squeegee and make a "flood stroke". This will prevent ink from drying in the screen. Once completed, lower the screen and make another stroke across the image, pressing firmly, to transfer the ink onto the substrate. Lift the screen and examine the image, to see if another stroke is needed. If so, then continue with another stroke. Step 7: Drying image. If another stroke is not required, lift up the screen and place the dryer over top of your completed image. Leave for approximately 1-2 minutes, but watch it carefully because it may burn. When the ink begins to steam, remove the substrate and print another. Step 8: Scrape off the excess ink with the spatula and return it to the pail. Make sure the squeegee and spatula are free from ink (it will wipe off just with paper towels or rags). Take the screen over to the washing station and spray the ink cleanup liberally over the screen. Scrub this in with the brushes located underneath the sink. Then, using the water gun, rinse off all the ink. Next, take the stencil remover in the pump, and spray the entire screen front and back. Allow this to sit for a few minutes, brush vigorously. Using the power gun, remove the stencil material. Step 9: De-grease screen. Once the screens are clean there is one last step, screen preperation. To remove any grease left on the screen after use brush in some screen prep or small amount of dish soap. Brush in both sides of screen and then rinse thoroughly. Put screens aside to dry. Screens are now ready to coat with emulsion. This is known as screen prep.

Transcript: SCREEN PRINTING By Emily Howard and Meredith Lawhead WHAT: - A printing technique that is used to support an ink-blocking stencil, using a woven mesh. - Screen printing is also known as silkscreen, serigraphy, and serigraph. - Commercial screen printing uses sensitzers which is much safer and less toxic. HOW IT WORKS: The stencil is used to open areas of the mesh to transfer ink that is pressed through the mesh onto a substrate. A substrate is a coating that covers the surface of an object. WHO WAS INVOLVED: -In 1907 screen printing was first patented by Samuel Simon in England. -In the 1910s Roy Beck, Edward Owens and Charles Peter created the first photgraphic screen. -Marc Tartaglia created a silk screening device. -Andy Warhol is the one who is usually given credit for making screen printing popular in the United States by identifying it as a serigraphy. -John Pilsworth developed a method called selectasine which introduced multi-color printing that uses the same screen. WHEN - Screen Printing started in China during the Song Dynasty (960- 1279) -After that, it spread to other Asian countries. -In the 1800's it was introduced to Western Europe but silk was hard to find and not accepted. WHY - Screen printing started as just a way to make expensive wall paper but soon grew. -Now it is used to do commercial printing and is also used by artists. -Commercial printers use screen printing for T-shirts, hats, CD covers, ect. -Screen printing is a method to mass produce a graphic. For example, posters or logos.

Transcript: Screen Printing Taylor Romine Graphics 2 4thHour 11/16/11 Print out design, check for quality and detail under the light, coat the screens witha photosensitive emulsion. Once the screen dries, it is placed on the vacuum light table with a 3000 watt metal halide light. After being exposed the screens are washed out with a pressure washer. There are color seperations and each color in the design needs a screen and must be blocked, taped, setup, and squeegeed. The screen will then be printed on the printing press placed on the pallet. After the design will dry on the t-shirt dryer.
