All artwork is preferred in vector format, saved to CS3 at full size as Adobe Illustrator or Illustrator pdf files with all fonts outlined. Raster graphics must be created at full size, at 300 dpi or higher and should have each color on its own layer. We accept the following hi-resolution file formats: CDR, AI, PDF, EPS, SVG, PSD, TIFF, and some hi-resolution JPGs. Vector files and color-separated, print-ready artwork is strongly encouraged and will eliminate or minimize all art charges. All fonts must be converted to outlines or the font file(s) must be included with artwork. If you have questions regarding the print readiness of your artwork, please contact your graphic designer or our art department. Please do not send any Microsoft documents for printing. There are no Microsoft programs that allow users to create hi-resolution graphics for professional screen printing. If you do submit your artwork as low-resolution graphics, it will be subject to design charges necessary to re-create your artwork as a print-ready graphic.
