Abstract
The print image device according to this invention is comprised of a rotatable member with an excessive ink removing liquid applied to the surface, which does not dissolve in a printing ink forming a print image and has a lower surface tension than that of the printing ink; a facing member for bringing a printed surface of a printed body into contact with the excessive ink removing liquid on the contact member by nipping and carrying the printed body having been printed between the contact member and the facing member; a supply device for supplying the excessive ink removing liquid to the contact member; and a cleaning device for removing the excessive ink removing liquid with the printing ink, sliding in contact with the contact member. Furthermore, a mixture of the excessive ink removing liquid and the printing ink is formed at an upstream position in the rotating direction, i.e. in a contact part formed by the contact member and cleaning means on the contact member, where the quantity of the excessive ink removing liquid is controlled to be larger than one third of that of the printing ink.
