Digital Imaging and Photo Emulsion Silkscreen

What is Silkscreen Printing?• Silkscreen is a stencil printing process.

• Ink is forced through a stencil made on fine-mesh polyester or silk fabric.

• Stencils can be made with cut paper, contact paper, photo emulsion, and other materials.

• Silkscreen printing is used to create multiple prints of your image, or image and text. Silkscreen can be used on paper, fabric, canvas, clay, and other flat surfaces.

Digital Process: Silkscreen prints from photos

• This is the digital version of the Photo Lith process.

• Instead of making a high-contrast print with Kodalith paper and chemicals, it can be done in Photoshop, and printed onto acetate transparencies.

• This is great for detailed images which would be ridiculously hard to hand-render.

• Color planning can also be done in Photoshop.
