ABSTRACT:
A double-side printing system has a printer section for printing images on the obverse side of a card, and a turning section for turning over the card sent out from the printer section and sending back the inverted card to the printer section so as to print various images on the reverse side of the card. The printer section performs printing of smooth color gradation images such as photographs with dye-sublimation color inks, and binary gradation images such as bar code patterns and letters with monochromatic thermal wax-transfer ink. The card having its obverse side printed with images is sent to the turning section and turned over 180.degree. so as to print other images on the reverse side of the card.
