Low colour art, also referred to as “flat design”
No gradients and no opacity changes
Needs to be simple enough to be cut out of colour paper and still be recognisable.
Screen printing

In screen printing you have a “screen”
Inside the screen is a very fine mesh material. It’s a solid, ridged frame with a fabric with very fine holes stretched over it.
The screen is coated with a chemical agent(look it up) across the whole of the screen. This is a high opacity chemical agent.
A negative is used on an acetate. It is developed, the chemical hardens only where light hit.
The screen is then cleaned, removing the unhardened chemical off.
Ink is pushed through the “hole” created from the developing using a squeegee. This creates an image on whatever is under the screen.
The limitations to screen printing is that you can’t have different opacities, a gradient or too many different colours. One way of creating the illusion of gradient however is to use halftones.
Halftone example
Registration is used when you have more than one colour. It is making sure that everything lines up.
