You should always provide artwork at the size you want it printed. (Sample 12"x13" cropped.) If you are unsure, please provide a basic visual mock up of the art on a garment so that we can choose an approximate size for you. Below are file formats we accept in order of preference, as well as what we do not accept:
Illustrator files (.ai) • Vector-based (.pdf) or (.eps) files • Fonts must be outlined
Photoshop files (.psd) • Common image files (.jpeg, .tiff, .png) must be at least print size and have a resolution of 300 DPI, fonts must be rasterized.
