摘要:
Disclosed is the print image treatment device formed of: a contact member on a surface of which an excessive ink removing liquid not dissolving in a printing ink forming a print image and having a lower surface tension than that of the printing ink is applied, the contact member being driven to rotate; a facing member for bringing a printed surface of a printing body into contact with the excessive ink removing liquid on the contact member by nipping and carrying the printing 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 an excessive ink with the excessive ink removing liquid. The nip width formed by the contact member and the facing member, which is defined as the dimension of the part with which the contact member and the facing member are in contact in the direction of the printing body being carried, is specified to be 0.5 mm or over.

A print image treatment device is formed of a supply device for holding an excess ink removing liquid, the excessive ink removing liquid not dissolving in a printing ink forming a print image and having a lower surface tension than that of the printing ink; a rotating contact member having an outer surface, on which the excessive ink removing liquid is supplied from the supply device; a facing member situated under the contact member for nipping and carrying a printing sheet between the contact member and the facing member, an excessive printing ink forming the print image on a printing sheet being transferred to the excessive printing ink removing liquid when the printing sheet contacts the contacting member; a cleaning device contacting the contact member for removing the excessive printing ink with the excessive ink removing liquid; and a separation device receiving the excessive ink removing liquid with the excessive printing ink. The excessive ink removing liquid is separated from the printing ink having been transferred from the printing sheet. The separation device includes a filter having the thickness and air-flow resistance indicated below: 0.05
摘要:
A quick-change material module of a stencil wiper assembly for wiping a stencil of a stencil printer includes a supply roller to receive a roll of material, a take-up roller to receive used material, and a drive to move the material across the stencil between the supply roller and the take-up roller. The supply roller is designed to move between an operating position in which the module functions to wipe the stencil and a changing position in which the supply roller is accessible to change the roll of material. A pivot mechanism is further disclosed for pivoting the supply roller between the operating and changing positions. A frame supports the supply roller, the take-up roller, and the drive. The pivot mechanism includes at least one pivot arm having one end rotatably attached to the supply roller and an opposite end pivotably attached to the frame. A method for changing a roll of material within a quick-change material module of a stencil wiper assembly designed to wipe a stencil of a stencil printer is further disclosed.
