Abstract
A recording method comprising the steps in the following order of: correcting a curl of a recording medium by applying heat and pressure to the recording medium; and forming an image on the recording medium by jetting ink onto the recording medium.
Claims10
An ink jet recording method comprising the steps of:
- forming an image on a recording medium comprising a support having thereon an ink absorptive layer comprising an inorganic pigment and a water soluble binder by jetting an ink onto the recording medium;
- and
- correcting a curl of the recording medium by applying heat and pressure to the recording medium,
- wherein the recording medium shows a curl value of between −10 and 10 mm after applying a heat and pressure treatment in the following condition to the recording medium having a curl value between −30 of −40 mm,
- wherein the condition of the heat and pressure treatment is:
- employing an apparatus comprising a φ30 mm circular iron cylinder having a heater in its interior as an upper roller and a φ30 mm silicone rubber roller as a lower roller, both of which are covered with a tetrafluoroethylene-perfluoroalkyl ether copolymer having a thickness of 100 μm;
- feeding the recording medium in so that the upper roller comes into contact with the surface of the ink absorptive layer;
- and
- subjecting the recording medium to the heat and pressure treatment under conditions of a nip width of 0.3 mm, a linear pressure of 32 kgf/297 mm, transporting rate of 10 mm/second and the surface temperature of the upper roller of 120° C.
