Abstract
A printing apparatus includes a transport for cards to be repeatedly scan printed with component colors. In the transport, a pair of belt rollers are fixed axially parallel in a frame, the belt rollers defining circumferential annular aligned grooves. Belts encircle the belt rollers, positioned in the grooves, and extend to define a virtual working bed on which the card is moved to be printed. Pinch rollers retain the card fixed to the belts. In sequence, cards are cleaned, magnetically processed and printed.
