Daler Rowney System 3 Removable Screen Block is for use with Printing medium, acrylic colours and Screen Drawing Fluid. Once the positive image drawn with Screen Drawing Fluid has fixed, Removable Screen Block is applied on the inside of the screen with a squeegee.
Once the drawing fluid is dry, the entire screen surface is then blocked out with System 3 Removable Screen Block, applied by squeegee. Again, once dry, the previously drawn image is washed out in cold water to leave an open-mesh positive image ready for printing. The screens can be reclaimed after printing by washing out the screen block with hot water and soap. Screen Block should be kept upright and stored at normal room temperature.
