Screenprints are created by pressing ink indirectly onto paper through a mesh screen.
I make small screen prints in my studio and large screen prints using workshop facilities at the Glasgow Print Studio. I create stencils from paper shapes, hand-drawn or computer-generated images and photographs. Photo-emulsion stencils are prepared at the Glasgow Print Studio. The stencil is laid under a large aluminium-framed polyester screen coated with UV light-sensitive emulsion, and exposed to UV light. Black marks block the light and prevent the photoemulsion from hardening. This unexposed emulsion is washed out of the screen mesh, leaving a robust, positive stencil. These stencils can be altered by blocking out additional parts of the screen using either parcel tape or photo-emulsion. Printing paper is laid on a vacuum bed (to prevent it from moving), the screen is positioned over the paper, and water-based ink is pressed through the open areas of the stencil using a squeegee. The printed image is identical to the original stencil: there is no reversal of the image. Multiple stencils can be over-printed to create multi-colour images.
