    • A variable data lithographic printing device comprises surrounding a printing cylinder a photosensitive layer coater, an exposure source, optionally a developer, an inking applicator, optionally a transfer system, and optionally an eraser. During printing operation, each surface areas of the rotating cylinder continuously undergo the cycle of coating, imagewise exposure, optionally developing, inking, printing of inked imaging to the receiving medium, and optionally erasing processes. The developing means can be omitted if an ink and/or fountain solution developable photosensitive layer is used. In an alternative design, the cylinder is replaced with a continuous supply of a ribbon with lithographic substrate surface. In another alternative design, the cylinder and the coater are replaced with a continuous supply of a pre-sensitized ribbon comprising on a substrate a photosensitive layer.

    • A method of color printing on packaging containers using transparent colors is described. The method is limited to the use of no more than two of the primary process colors. For many images primary process colors are not needed at all. Preferably, only two transparent inks will be used. In some cases an opaque ink may be applied first as a masking image underlying a part or all of the transparent ink overprint. In other cases the opaque ink may be applied last as a masking print over part of the image. The method can be used on any substrate color but it is particularly useful on dyed papers or unbleached kraft brownboard. While color reproduction is not totally accurate, nor is this expected in a colorimetric sense, surprisingly attractive and realistic images generally faithful to the original are attainable.
    • 描述了使用透明颜色的包装容器上的彩色印刷方法。 该方法仅限于使用不超过两种主要工艺颜色。 对于许多图像,根本不需要主要的处理颜色。 优选地,仅使用两种透明油墨。 在一些情况下,可以首先将不透明的油墨施加作为部分或全部透明油墨叠印之下的掩蔽图像。 在其他情况下,不透明墨水可以最后施加在图像的一部分上作为掩模印刷。 该方法可用于任何基材颜色,但在染色纸或未漂白牛皮纸棕板上特别有用。 虽然色彩再现并不完全准确,但在色彩方面也没有这样的预期,通常忠实于原稿的惊人的,逼真的图像是可以实现的。

    • Separate air curtains of low pressure, high flow volume air are discharged onto the leading inking form roller on the feeder side and onto the trailing inking form roller on the delivery side of the plate cylinder to evaporate water entrained with the ink and which has migrated from the printing plate to the inking form rollers as a result of uneven application of water to the plate cylinder. A pair of elongated distribution manifolds are mounted on the press in proximity to the inking form rollers, one manifold directing a curtain of air onto the inking form roller and adjacent vibrator roller on the feeder side, and the other manifold directing a curtain of air onto the inking form roller and adjacent vibrator roller on the delivery side of the plate cylinder. Gap streak caused by periodic interruption in the transfer of dampening solution to the printing plate is eliminated by the dual air curtains which evaporate dampening solution picked up from the printing plate by the inking form rollers before the excess dampening solution has an opportunity to infiltrate the inking roller train.
