Silkscreen Printing

What is Silkscreen Printing?
The printing technique, is applying a non ink soluble emulsion on a fine woven fabric stretched across a flat rectangular frame and tensioned very tightly, so that when the printing ink is pressed down using a squeegee, the ink passes through the holes in the mesh where there is no emulsion onto the substrate.

ARTWORK To get the artwork onto the mesh, Negative Film is used, and the image is ‘burnt’ onto the mesh with a powerful light. The non ink soluble emulsion is spread across the entire mesh, then, exposed to light. Just like traditional photography, the emulsion is exposed, then the un-exposed regions are washed away. This leaves some hardened emulsion (areas that will not print), and some clean mesh

Screen Printing has more ‘start’ costs and ‘set up’ costs compared to other sign making techniques, however, once these cost are approved, the actual sign production speed is faster. This allows large quantities of the same image to be cheap.

An Example, when we print car decals , most times, the order is 200 units in two colours. This is very fast, the film cost and set up cost is quickly out surpassed by production speed.

Different Resolutions. Screen Printing is lower in resolution to digital. At 45 lpi, this equates to approx 75 dpi, and is regardless of size. All printing using a Silk Screen is the same resolution.
