(3) Problems to be solved by the invention Therefore, when two webs are stacked and passed through a drying device, the vapor layer of the ink solvent is removed on the outer surface of the superposed webs by jetting cooling air. The inner surface of the superposed webs comes into contact with the cooling roller without removing the vapor layer of the ink solvent. The vapor layer of the ink solvent lowers the heat transfer coefficient between the cooling roller and the web, and when the printing speed increases, the cooling capacity of the cooling roller becomes insufficient.

Numeral 11 is designed to blow air from the top and bottom onto the two-layered webs W1 and W2 that run with cooling nozzles that send cold air. The cooling rollers 12 of the cooling device are provided in pairs one above and one below, and cooling water circulates in each of the cooling rollers 12a, 12b, 12c, 12d. After drying, the upper web W1 has cooling rollers 12c and 12d, and the lower web W2 has cooling rollers 12a and 12b.
To be cooled through a Z-shape. The auxiliary cooling device 13 of the present invention is provided between the webs W1 and W2. As shown in FIG. 2, this auxiliary cooling device 13 has a frame in which a cooling air injection pipe 14 is provided in a width direction of webs W1 and W2 via a bracket 18.
A plurality of air on-off valves 15 and nozzles 16 connected to the air on-off valves 15 are arranged in the cooling air injection pipe 14 in a uniform arrangement.
The cooling air is connected to the cooling air injection pipe 14 through a pipe 19 from a supply source (not shown). Therefore,
The printed webs W1 and W2 are cooled by receiving cool air from the cooling nozzles 11 while being cooled by cooling rollers 12a,
