We accept most file formats, including PNG, JPEG, and SVG. However, we recommend using a high-resolution PNG or SVG file for the best results.

Currently we print with the industry standard, plastisol ink.  We are testing water-based ink that will give an incredible feel ("hand") to the print and will be releasing that as an option as soon as the specs are dialed in.  

Yes!  We do offer custom color matching service for your prints.  Custom color charge is $20 for standard inks.  We also offer shimmer (not quite glitter, but close) inks as well.  

We have many different suppliers of shirts, but our favorite is Sanmar.com.  There you can find almost any style of shirt you're looking for.  Once you find something you like, shoot us an email!
