Step 1 - Be sure to use the recommended settings and profile for the material you are using.  If you are starting from square 1 and do not have recommended setting or profile, use a like media type on the printer that relates to your media loaded.  If you choose a media type like the material you have loaded and the inks are still not drying, up the heat on the platen and post heaters.   If the heat is maximized and the product is still not dry to the touch (ink smears), contact the manufacturer of the product for support.  The manufacturer or supplier of material is responsible for supplying proper optimized media settings.
