    • A flexible image transfer blanket is provided which has a non-extensible backing which is easy to mount onto conventional blanket cylinders, which requires no packing (but which can be used with packing), which does not need to be retensioned during operation, and which prints to the gap better than conventional fabric-reinforced blankets. The image transfer blanket is adapted to be mounted onto a blanket cylinder and includes first and second ends, with at least one of the first and second ends being adapted to be inserted into an axially-extending gap in the blanket cylinder. The blanket includes a image transfer surface layer, at least one woven fabric ply, and a non-extensible base layer. The at least one woven fabric ply includes both warp and weft fibers, with the weft fibers being oriented so that when the blanket is mounted on the blanket cylinder the weft fibers extend circumferentially about the blanket cylinder.
    • 提供了一种柔性图像转印毯,其具有易于安装到常规橡皮布滚筒上的不可延伸的背衬,其不需要在操作期间不需要再张紧的包装(但可以与包装一起使用),并且其中 打印到差距比传统的织物增强毯子更好。 图像转印毯适于安装在橡皮布滚筒上并且包括第一和第二端,其中第一和第二端中的至少一个适于插入橡皮布滚筒中的轴向延伸的间隙中。 毯子包括图像转印表面层,至少一个机织织物层和不可伸长的基底层。 所述至少一个编织织物层包括经纱和纬纱两者,其中纬纱纤维被定向成使得当毯子被安装在橡皮布滚筒上时,纬纱纤维围绕橡皮布滚筒周向延伸。

    • A continuous image transfer belt which is useable in a variable image size offset press system and which is adapted to permit the press to print a variety of different sized printed matter is provided. The image transfer belt includes at least one base ply, at least one layer of a compressible material over the base ply, and a surface ply over the layer of compressible material Preferably, the belt is continuous. The belt is used in an offset printing system having the capability to print variable-sized images. The system includes a source of ink; at least one plate cylinder and a replaceable sleeve for the plate cylinder, and a printing plate which is adapted to receive ink from the ink source. The system also includes at least one blanket cylinder; the image transfer belt positioned to contact the printing plate in a nip formed between the plate and blanket cylinders; an image transfer belt tensioning system to register the image transfer belt to the blanket cylinder position in the area of desired image transfer; and an image belt cleaning station adapted to remove residual ink from the surface of the belt.
    • 提供了一种连续的图像转印带,其可用于可变图像大小的胶版印刷机系统中,并且适于允许印刷机印刷各种不同尺寸的印刷品。 图像转印带包括至少一个基底层,在基底层上的至少一层可压缩材料层,以及可压缩材料层上的表面层。优选地,带是连续的。 皮带用于具有打印可变尺寸图像的能力的胶版印刷系统中。 该系统包括一个墨源; 至少一个印版滚筒和用于印版滚筒的可替换的套筒,以及适于从墨水源接收墨水的印版。 该系统还包括至少一个橡皮布滚筒; 所述图像转印带被定位成在形成在所述板和橡皮布滚筒之间的辊隙中接触所述印刷版; 图像转印带张紧系统,用于将图像转印带注册到所需图像转印区域中的橡皮布滚筒位置; 以及适于从带的表面去除残留墨的图像带清洁站。
