Abstract:
PROBLEM TO BE SOLVED: To provide an ink mist recovering method, by which a re-removing work of the ink mist recovered and adheringly accumulated on mechanisms can be easily executed outside a printing part without making a work in the printing part at the time of printing more difficult than ever. SOLUTION: In this ink mist recovering method, at the neighborhood of a plate cylinder 110 side position, in which a sheet 100 intended for printing is released from a printing pressure by the plate cylinder 110 and the impression cylinder 120 of the printing part of a gravure printing machine, an air main flow 11 flowing parallel to the rotating shaft of the plate cylinder 110 is generated and then an air accessory flow, which joins to the main flow 11 due to the becoming of the static pressure of the main flow 11 smaller than the ambient air pressure, so as to guide the ink mist generating at the printing part with the accessory flow to the main flow 11 in order to effuse the ink mist-containing main flow 11 to an ink mist recovering part 20 provided outside the printing part, resulting in recovering the ink mist.

Abstract:
PROBLEM TO BE SOLVED: To provide a dampening water removing device for enabling to remove an excess dampening water by efficiently utilizing air and an offset printing method for enabling to obtain a high quality stable printed material by employing the dampening water removing device without using the temperature controlling device in a printing press roller. SOLUTION: An offset printing press equipped with the excess dampening water removing device setting to blast air tangent to an ink roller covered with an ink film mixed with the dampening water therewithin, the offset printing method and a printed material obtained by the offset printing method are dealt.

Abstract:
PROBLEM TO BE SOLVED: To achieve an optimum newspaper printing quality using waterless lithographic printing. SOLUTION: The method is to adjust the temperature of the rotating constructing members (03; 07; 12; 13; 14) or the plate cylinder (03) with fluid inside while operating a printing group, and thus to adjust the range of ink viscosity existing on the printing group cylinders (03; 07) within from 6Tack to 9.5Tack. The targeted value or the maximum value given to the temperature control device is changed so as to adjust or to maintain the viscosity. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To decrease a cost for preventing superheating which may be generated in a direct driver by further developing a direct coupled driver for a drum in the direct driver for the drum of a processing machine. SOLUTION: The direct driver 7 comprises so as to circulate a temperature adjusting agent in the direct driver 7 and an inking system 8 by being connected to a temperature regulator 9 through circuits 13, 14, 15, 16, 18, 20 on a pipe side and by being connected to the temperature regulator 9 on the pipe side and by connecting at least more one temperature adjustable apparatus, for example, an inking system 8 to the temperature regulator 9 on the pipe side.
