ーラを汚し、いわゆるブロッキング現象が発生する。However, in the recent printing line, since the printing paper travels at high speed and passes through the drying device in a short time because of high-speed printing, the printing paper is printed on the paper surface when leaving the drying device. Accompanied by ink solvent vapor. When the solvent vapor of the printing ink is cooled by the cooling roller of the cooling device together with the printing paper, the solvent vapor of the printing ink condenses into tar, and the tar of the solvent stains the printing paper and the cooling roller, so-called blocking phenomenon. Occurs.

However, in modern printing lines, because the dryer is for high speed printing and performance is improved, the solvent vapor of the printing ink exiting the dryer with the printing paper is small. That is, a device for collecting and purifying a large amount of solvent vapor is large-scale and expensive.

グ現象が発生しない。In the present invention, before the printing paper comes into contact with the first cooling roller of the cooling device, the air flow of the first air nozzle causes the solvent vapor of the printing ink accompanying the printing paper surface coming into contact with the first cooling roller. Since the printing paper is blown off to the side, the solvent vapor is not cooled by the first cooling roller. Further, before the printing paper comes into contact with the second cooling roller of the cooling device, the air flow of the second air nozzle causes the solvent vapor of the printing ink accompanying the printing paper surface coming into contact with the second cooling roller to the side of the printing paper. Since it is blown off, the solvent vapor is not cooled by the second cooling roller. Therefore, the solvent vapor of the printing ink, which has left the drying device together with the printing paper, is not cooled by the cooling roller of the cooling device, so that the blocking phenomenon does not occur.
