Abstract
Disclosed is a fluid deposition apparatus comprising (a) a fluid supply, (b) a porous fluid distribution member in operative connection with the fluid supply, enabling wetting of the fluid distribution member with a fluid, and (c) a porous metering membrane situated on the fluid distribution member, whereby the metering membrane enables uniform metering of the fluid from the fluid distribution member onto a substrate.
Claims21
A fluid deposition apparatus comprising (a) a fluid supply, (b) a porous fluid distribution member in operative connection with the fluid supply, enabling wetting of the fluid distribution member with a fluid, and (c) a porous metering membrane situated on the fluid distribution member, whereby the metering membrane enables uniform metering of the fluid from the fluid distribution member onto a substrate.
A fluid deposition apparatus according to claim I wherein the fluid distribution member comprises a polyurethane foam.
An apparatus comprising (a) a substrate supply, (b) a fluid deposition apparatus comprising (1) a fluid supply (2) a porous fluid distribution member in operative connection with the fluid supply, enabling wetting of the fluid distribution member with a fluid, and (3) a porous metering membrane situated on the fluid distribution member, whereby the metering membrane enables uniform metering of the fluid from the fluid distribution member onto a substrate;
- (c) an ink jet printer for placing marks on the substrate in an image configuration;
- and (d) a substrate advancing system in operative relationship with the ink jet printer and the fluid deposition apparatus, whereby the substrate is advanced from the substrate supply to the fluid deposition apparatus and the ink jet printer.
A process which comprises (a) providing an apparatus comprising (1) a substrate supply;
- (2) a fluid deposition apparatus comprising (i) a fluid supply, (ii) a porous fluid distribution member in operative connection with the fluid supply, enabling wetting of the fluid distribution member with a fluid, and (iii) a porous metering membrane situated on the fluid distribution member, whereby the metering membrane enables uniform metering of the fluid from the fluid distribution member onto a substrate:
- (3) an ink let printer for placing marks on the substrate in an image configuration;
- and (4) a substrate advancing system in operative relationship with the ink jet printer and the fluid deposition apparatus, whereby the substrate is advanced from the substrate supply to the fluid deposition apparatus and the ink let printer;
- (b) incorporating a fluid into the fluid deposition apparatus;
- (c) incorporating into the printing apparatus an ink composition;
- (d) applying the fluid to the substrate with the fluid deposition apparatus;
- and (e) causing droplets of the ink composition to be ejected in an imagewise pattern onto the substrate.
