Hi Ingy,
You are correct that for vector images, it is limited to three colors, however three colors does not have to be limiting. As with vectors, you can then choose any of our
Flex or Flock colors we offer, like glow in the dark, sparkle, reflective, glitter, and a variety of other colors. If you are thinking comic style products, then check out the shop of comic artists
Katz & Goldt, on of our top German shops! They offer a variety of designs in 1-3 colors and if you click on the design, then you can see the range of products, product colors, and design colors they can offer with their vector designs.
For digital images, Spreadshirt does allow printing on colored apparel as well. In the US, we recently released Digital Direct, which prints the ink directly onto the product. With Digital Direct, you can print any design on colored and white apparel. Currently, there are a limited amount of products which use Digital Direct on colored apparel, however we will eventually replace all of our products and older Digital Printing methods in the future with Digital Direct. For colored apparel and products which are not supported by Digital Direct at this time, we do offer Digital Transfer Overlay, which prints digital images on colored apparel, with some limitations. If you upload a transparent png file, then your transparency will be supported. You can read more about our Digital printing
here.
Thanks,
Temple
