The invention discloses a spot-color printing method for a paper-plastic product. The spot-color printing method specifically comprises the following steps: 1, when a printing machine needs to be usedfor printing, a mounting frame is pushed firstly, thus universal wheels at the bottom of the mounting frame rotate, the mounting frame is moved to the position where printing processing is needed, supporting feet at the bottom of the mounting frame are rotated, thus the lengths of the supporting feet and the mounting frame are changed, thus the supporting feet directly make contact with the ground, and the position of the mounting frame is fixed; and 2, two symmetrically-arranged limiting plates are moved. By moving the two symmetrically-arranged limiting plates, an adjusting sliding block slides in an adjusting sliding groove, the distance between the limiting plates is adjusted, a printing steel plate is placed between the two limiting plates, the distances between the limiting plates and the connecting plate a
