This is then placed on a light table, with the screen placed on top. A vacuum bag and a piece of foam is used to ensure good contact between the film and the screen.

Edges of the screen are masked off with tape, and the screen is locked into place on the vacuum table. This layer is being done with a split fountain; three different colors of ink blend together on the screen to create a gradient.
Ink transfers through the screen to the paper beneath.
The ink mixes continuously, producing a unique pattern of swirls that makes no two posters alike.
