The type of artwork you can send will depend on the printing process that is used for that particular product. You can supply artwork in either Vector files (.eps , .pdf, .ai) or Raster (pixel) (.png , .jpg, .tiff). Vector files are suitable for all types of print, whereas Raster (pixel) files are only suitable for full colour/process/transfer print and cannot be used for screen printing, debossing or engraving.
