A compact machine consistently prints sharp, silk screened images on balloons. This is accomplished by a machine with a rotatable table and a number of operating stations located around the perimeter of the table. One station inflates the balloons to a predetermined size. At a print station a silk screen is lowered onto the balloon and a wiper makes a single pass across the screen to print on the balloon. (On the succeeding balloon the wiper will move in the opposite direction.) The wiper moves in a direction transverse to the usual orientation of lines of print on a balloon. The single pass printing and the direction with respect to the usual printed image orientation assure sharp images over extended printings. The balloon remains inflated and dries for about the next one-half rotation of the table, and it is then discharged onto a conveyor where infrared heat shrinks it to its original size.
