Mixing garment sizes and colours is a great way of keeping costs low. As long as you are using the same design and ink/thread colours there will be no extra charge. Changing ink printing colours is possible, if you are not switching from dark to light coloured garments. This is because you may require an underbase on dark coloured garments – see Screenprinting FAQs for more details on using an under base. There will be a small charge incurred for changing ink/thread colours.
