The application relates to the technical field of packaging boxes, in particular to a packaging color box surface printing process, which comprises a feeding process, a printing process and a discharging process. In the feeding process, a clamp is used to send the packaging box to the position of a transfer roller on a printing equipment rack. In the printing process, a color printing pattern on a transfer paper is transferred to the outer side wall of the packaging box through the transfer roller on the printing equipment rack. In the discharging process, the clamp is used to send the packaging box to the discharging position for discharging. The clamp composed of a main shaft, a mounting column and a clamping plate supports and clamps the inner side wall of the packaging box, so that the packaging box can stably abut against the side wall of the transfer roller in the printing process, the transfer effect is effectively guaranteed, and the printing forming effect of the color box surface is guaranteed.
