The Birds & The Bees

I use two different print types on my shirts, for simple 1-3 color stuff I use Flex Printing, which is basically like little thin bits of polyeurathine cut into shapes by machines. For more complicated designs with over 3 colors, gradients, or tiny details, I use Digital Direct Printing, which employs big printers that are basically overgrown injets that spew ink directly onto the fabric. Each has some plusses and minuses, so if you are curious you should read more about them from my fulfillment company: FLEX PRINTING DIGITAL PRINTING
