METHOD OF DRYING PRINTED MATERIAL AND APPARATUS THEREFOR

摘要

[PROBLEMS] To carry out drying of printing ink with the use of nanosized high-temperature dry steam. [MEANS FOR SOLVING PROBLEMS] Nanosized high-temperature dry steam having undergone nanoorder clustering is generated and jetted to the print side of printed material so that the nanosized high-temperature dry steam imparts intramolecular vibrational energy to the ink of the print side. Consequently, the nanosized high-temperature dry steam of nanoorder not only passes through fiber pores of the printed material but also collides with the ink of the print side. The nanosized high-temperature dry steam having collided with the ink of the print side imparts thermally excited energy as intramolecular vibrational energy to the ink consisting of polar molecules. The ink is dried by the intramolecular energy.
