The utility model relates to the field of color printing, in particular to a positioning device for composite printing. The problem that a printing roller corresponds to a printed product in the composite printing process is solved. Comprising an auxiliary positioning wheel 1, a wheel detector 2, a paper detector 3 and a controller, the auxiliary positioning wheel and a printing roller are coaxially installed, the auxiliary positioning wheel and the printing roller rotate synchronously, an auxiliary positioning label is attached to the circumferential face of the auxiliary positioning wheel, and the auxiliary positioning wheel is made of resin materials. The corresponding matching efficiency of the printed product and the printing roller is improved, and meanwhile it is guaranteed that in the printing process, the printing roller pattern and the printed product are correspondingly printed and matched. 本实用新型涉及彩印印刷领域，特别是一种用于复合印刷的定位装置。解决复合印刷过程中印刷辊和印制品对应的问题。包括辅助定位轮1、轮检测器2、纸检测器3和控制器，辅助定位轮与印刷辊同轴心安装，且辅助定位轮与之同步转动，辅助定
