what file does the artwork have to be in to do seperations for silkscreen? vector? im airbrushing on metal panel, taking pic , and uploading as jpg. im told the printer would have to redo my art on pc in order to convert to useable file. if i airbrushed on paper, and scanned into pc, what file would it be at that point? would you still have to redo the art , or can it be easily converted at that point? i dont want to airbrush on metal if its easier to convert from paper, scan. im no computer guy. wish i was tho.
