Squeegee Basic Facts and Use
The squeegee is a hard rubber like blade attached along one edge to a (most often wooden) handle. The even edge of the blade is used to drag across the open image of the screen pulling the ink with it and pressing the ink in the open areas of the screen - through the screen to be deposited on the t-shirt of your size so you can wear the art. The stiffness of the blade, the shape of the blade edge, the angle of the pull (angle of the squeegee to the screen), the pressure paced on the squeegee during the pull and even the speed of the pull all effect the amount of ink pushed through the screen an onto or into the cotton t-shirt beneath the screen.
Sharp edged squeegees are used for fine lines and sharp detail or to print less in to capture fine details (un-inked areas) in areas of heavy ink. A Rounded edged squeegee is used for large solid areas of ink that need to be thick in order not to be, too often, salt speckled with thinly printed areas. A t-shirt is a course surface of woven cotton fibers. It sucks up ink compared to paper. Each surface in screen printing and each ink type are different and require printing adjustments according to their nature. Plastic and nylon (a type of plastic) require harsh solvents for a base and give these solvents off into the atmosphere when dried and cure. They require accurate driers that suck up electricity and require ventilation systems to operate. The ink takes a very long time to dry in the screen. Water based inks dry fast. The printer must work fast and solve problems fast. Breaks must be short - very short! Most print runs must be to completion before a break or with complete clean-up of all screens. Screen printing in the hands of an artist is not just a technical skill - it is an art. |
