This weeks session took the shape of looking at the design spraying process. We started out by making some simple stencils with which we were going to create ‘test prints’ later on in the session. We then looked at paint viscosity as it plays a big part in creating the right mix for spraying. Using a compressor powered airbrush we then sprayed the test stencils. While doing this we discussed the ‘Venturi effect’ & how it is a key factor in the use of the airbrush & spray cans. Science, Art & Technology in harmony!
This is what Jonah had to say about the session: “This week we learnt about the airbrush and how it uses the Venturi effect. We first went and cut some ‘Santa Cruz’ stencils. We then learnt about the Venturi effect, which is when air gets blown over the paints and picks it up and separates the paint into tiny pieces. Therefore making it sprayable. After we had a go at airbrushing on scrap pieces of wood with the ‘Santa Cruz’ stencils. We also learnt about watering down the paint to make it runnier. This is called viscosity.”
