The present invention provides a gravure printing device for printing on both sides of an opaque printing material, which reduces a printing failure by easily adjusting a focus of an opaque printing material, wherein both sides thereof are printed, and printing the printing material since a pair of sensors are mounted to individually detect a color corn formed at an edge on both sides of the opaque printing material. The gravure printing device is mounted in order for a gap between the two sensors to be 2cm or less. So, the color corn formed at predetermined intervals can be accurately detected. Thereby, the gravure printing device can print on the both sides of the opaque printing material in order for the focuses of a printing shape, individually formed on the both sides of the opaque printing material, to accurately overlap each other without dislocation. |
