    • A packet for daylight-handling of photosensitive film and a cooperating holder mountable on a camera back. The packet has film removably attached to a carrier. The carrier has, at one end, an asymmetrical tab bearing adhesive material and, at its opposite end, a transverse light-locking element. Telescopically receivable over the carrier and film is a light-shielding envelope. The envelope has an open end that is closable by engagement with the light-locking element and a closed end with a sealing area that overlies and, when grasped, adheres to the tab, to prevent inadvertent separation of the envelope from the carrier. An adjacent area, not overlying the tab, is graspable for pulling the sealing area free of the tab and the envelope away from the film, to permit intended exposure. The envelope also has, near its open end, a stop strip for limiting envelope movement. The packet is slidably insertable into, and withdrawable from, the cooperating holder, which includes a spring-loaded pressure-applying member for maintaining the film in an exposure plane, a spring-loaded latching member engageable with the light-locking element to retain the carrier in place, a spring-loaded blocking member engageable with the stop strip to limit envelope movement while the carrier is retained, and a releasing member that is manually actuable for negating the spring-loadings on the pressure-applying, latching, and blocking members, to permit unrestricted withdrawal of the packet from the holder.
    • 用于光敏胶片的日光处理的分组和可安装在相机背面的配合支架。 该包装袋具有可移除地附接到载体的膜。 载体在一端具有不对称的片状物,其粘合剂材料在其相对端处具有横向光锁定元件。 承运人和电影上的望远镜可接收的是遮光信封。 外壳具有可通过与光锁定元件接合而封闭的开口端,并且封闭端具有覆盖的密封区域,并且当被抓持时粘附到突片上,以防止信封与载体的意外分离。 可以抓住相邻的区域,而不是覆盖突片,用于将没有突片和信封的密封区域拉离胶片,以允许预期的曝光。 信封在其开口端附近还具有用于限制包络线移动的止挡条。 所述包装可滑动地插入到所述配合保持器中并且可从其中抽出,所述保持器包括用于将所述膜保持在曝光平面中的弹簧加载的压力施加构件,与所述光锁定元件接合的弹簧加载的闩锁构件, 载体就位,弹簧加载的阻挡构件,其可与止动带接合,以在载体保持时限制包络运动;以及释放构件,其可手动地致动以抵消施加压力,闭锁和阻塞构件上的弹簧载荷 以允许从包装盒不受限制地取出包装。

    • A method and system for reducing registration errors in a printing system are disclosed. A plurality of tension zones is defined in the printing system. Tension on the web in one tension zone is controlled independently of the tension on the web in the other tension zones. The printing system also includes at least one roller for each tension zone. The rollers receive tension control commands and control the amount of tension on the web in their respective tension zones. The printing system is used to print a first copy of the print job on the web and a plurality of registration errors is determined. Tension control adjustments are computed for each tension zone based on the registration errors. The tension control adjustments are used to adjust the tension control commands to the rollers to print a second copy of the print job, thereby reducing registration errors.
    • 公开了一种用于减少打印系统中的配准错误的方法和系统。 在打印系统中限定了多个张紧区域。 在一个张力区域上的幅材上的张力独立于其它张力区域上的幅材上的张力而被控制。 打印系统还包括用于每个张力区的至少一个辊。 辊子接收张力控制命令并控制幅材在其各自的张力区域中的张力量。 打印系统用于在网页上打印打印作业的第一副本,并且确定多个注册错误。 基于注册误差计算每个张力区域的张力控制调整。 张力控制调整用于调节对辊的张力控制命令,以打印打印作业的第二副本,从而减少注册错误。
