We use an industrial grade DTG printer which prints in 32 bit colour so there are almost no limitations in colour for print. We do recommend that you read:
For embroidery we use 18 needle embroidery machines so each design is limited to a maximum of 6 different colours (there are different needles used for different materials). However matching embroidery thread colours is a bit more complicated. We use Madeira Polyneon Green thread which is made from 100% post-consumer waste PET plastic bottles using an energy-saving production process. Polyneon Green is available in limited solid colours so we need to visually match them to your design. We recommend ordering a sample before you publish products to your store.
