    摘要： A method of printing uses a liquid applicator to apply a coating solution ontaining polyvinyl pyrrolidone or a polyvinyl pyrrolidone copolymer to an intermediate transfer medium. An image is printed onto the intermediate transfer medium using an ink jet printing device. The coating solution contains an organic solvent, which is preferably a glycol solvent or a diol solvent. Suitable solvents include trimethylene glycol, diethylene glycol, propylene glycol, di propylene glycol, tri propylene glycol, 1,2 butane diol, 2 pyrrolidone, gamma butyrolactone and glycerol. The coating solution is applied in an amount of 0.01 to 10 mg/cm2. The coating solution may contain 0.01 to 20 wt. % of polyvinyl pyrrolidone or a polyvinyl pyrrolidone copolymer, 5-95 wt. % of an organic solvent and 5-95 wt. % water. More preferably, the coating solution contains 0.01 to 15 wt. % of polyvinyl pyrrolidone or a polyvinyl pyrrolidone copolymer, 5-95 wt. % of an organic solvent and 5-95 wt. % water. Most preferably, the coating solution contains 2 to 8 wt. % of polyvinyl pyrrolidone or a polyvinyl pyrrolidone copolymer, 5-95 wt. % of an organic solvent and 5-95 wt. % water. The PVP should have a molecular weight greater than 400,000, more preferably greater than 750,000 and most preferably within the range of from 850,000 to 1,500,000.

    摘要： The invention provides a test fluid for detecting coating flaws in a coated web and a method for testing a web coating system. The test fluid includes, water, a polyol, a surfactant, a radiant energy activated tracer compound and an organic solvent selected from the group consisting of an alkylene glycol and a dialkylene glycol. The test fluid is used to identify deficiencies in the web coating system so that adjustments to the web coating system may be made before assembling the coating system in an ink jet printer.

    摘要： A coating apparatus for applying a coating liquid to a printing substrate. The apparatus includes a rotatable first roll, and a rotatable second roll positioned adjacent to the first roll and defining with the first roll a first nip through which the printing substrate passes. The apparatus also has a metering device for applying a layer of coating liquid onto the second roll, which in turn transfers the coating liquid to the printing substrate. The apparatus further has a controller that communicates with at least the second roll, wherein the controller performs the steps of determining whether the idle time of the second roll is longer than a predetermined threshold, setting a pre-spin flag if the idle time of the second roll is longer than a predetermined threshold, and directing the second roll to perform a pre-spin upon the presence of the pre-spin flag.

    摘要： The invention provides an improved paper coating system for ink jet printing applications. The system includes an ink jet printer containing an ink jet pen and a paper coating device for coating a print media with an effective amount of coating composition prior to printing thereon. The coating composition preferably includes from about 0.25 to about 20% by weight of a first component selected from the group consisting of polyvalent metal salt and organic acid, a second component consisting of from about 1 to about 20% by weight amine polymer, from about 0.25 to about 2.0% by weight surfactant and from about 25 to about 96% by weight glycol-based solvent having a surface tension ranging from about 25 to below about 45 dynes/cm. Since the coating composition is free from ethylene glycol-based components, the composition is safer to use and less harmful to humans and the environment. The composition has also been found to provide improved ink drying with less bleeding or smearing of image.
