Screen setups are based on the amount of colours in your design, so a screen needs to be set up for each colour. If you are printing a light colour on a dark or light coloured garment, we strongly recommend printing an under base to keep the colours vibrant. This also counts as an additional screen/colour; so, for example, printing white on black would count as a 2 colour print. If you have any questions about how many screen setups your design might need, get in touch with us.
