Daler Rowney : Screen Printing

System 3 Acrylic Printing Medium is specially formulated for use with System 3 Original. The two combine to produce economical, low-odour, water-based screen printing ink which is regarded worldwide as the finest of its kind and, being solvent-free, is ideal for use in schools, studios and at home. Printing Medium slows down on-screen drying of acrylic colour, reducing the risk of screen blocking, making it easier to wash out. Screens, kept moist, will wash out easily with soap and water. The medium can be thinned with water. Even after mixing with Printing Medium, System 3 Original colours retain great density of colour, and very substantial covering power can be achieved on paper, card and board without undue cockling. If printing on textiles, System 3 Textile Printing Medium should be mixed in roughly equal quantities with System 3 Original colours. The medium performs very well on cotton, cotton mixes, most natural fibres, silk and synthetics. Blue System 3 Screen Drawing Fluid is applied by brush directly to the screen to create a drawn image. It can be applied neat but often requires some dilution with water in areas with finer detail. Once dry, the entire screen surface is blocked out with System 3 Removable Screen Block, which is applied with a squeegee. After drying, the drawn image is washed out in cold water to leave an open-mesh positive image ready for printing. After printing, screens can be reclaimed by softening up the block with very hot water then vigorously washing out the Screen Block with a suitable brush and a very strong soap solution such as undiluted washing-up liquid. Screen Block should be kept upright and stored at normal room temperature.
