Publication number: 20210291562Abstract: The wind velocity of the air injected by the air-blow dryers 7a, 7b is lower than that of the air injected by the air-blow dryers 7c, 7d. That is, since a large amount of moisture remains on the front surface M1 of the printing medium M passing through the air-blow dryers 7a, 7b, the printing medium M is dried while the flow of the aqueous inks is suppressed by injecting the air at a lower wind velocity. On the other hand, the moisture decreases on the front surface M1 of the printing medium M dried by the air-blow dryers 7a, 7b and the fluidity of the aqueous inks is reduced. Accordingly, the drying of the printing medium M is promoted by injecting the air at a high wind velocity to the printing medium M passing through the air-blow dryers 7c, 7d.Type: ApplicationFiled: March 4, 2021Publication date: September 23, 2021Inventors: Kenta Hiramatsu, Yoshikuni Takeichi, Takeshi Matsuda, Keisuke Hirai, Ryota Uemura

Publication number: 20210291563Abstract: In the air-blow dryers 7a, 7b, the back surface M2 of the printing medium M is supported by the rollers 74 while the hot wind is injected from the nozzles 76u to the front surface M1 of the printing medium M. By extending the printing medium M along the rollers 74, the evaporation of the moisture can be promoted by the hot wind while the formation of creases of the printing medium M is suppressed against the influence of the temperature distribution caused by the latent heat of the moisture on the printing medium M. After a certain amount of the moisture is evaporated, the temperature of the printing medium M becomes relatively uniform. In the air-blow dryers 7c, 7d, the printing medium M is dried by injecting the hot wind to the printing medium M from the nozzles 76l and 76u from both sides.Type: ApplicationFiled: March 4, 2021Publication date: September 23, 2021Inventors: Ryota Uemura, Keisuke Hirai, Yoshikuni Takeichi, Takeshi Matsuda, Kenta Hiramatsu
