Aluminum Lithographic Printing Plates

The merchandise covered by these orders are aluminum lithographic printing plates. Aluminum lithographic printing plates consist of a flat substrate containing at least 90 percent aluminum. The aluminum-containing substrate is generally treated using a mechanical, electrochemical, or chemical graining process, which is followed by one or more anodizing treatments that form a hydrophilic layer on the aluminum-containing substrate. An image-recording, oleophilic layer that is sensitive to light, including but not limited to ultra-violet, visible, or infrared, is dispersed in a polymeric binder material that is applied on top of the hydrophilic layer, generally on one side of the aluminum lithographic printing plate. The oleophilic light-sensitive layer is capable of capturing an image that is transferred onto the plate by either light or heat. The image applied to an aluminum lithographic printing plate facilitates the production of newspapers, magazines, books, yearbooks, coupons, packaging, and other printed materials through an offset printing process, where an aluminum lithographic printing plate facilitates the transfer of an image onto the printed media. Aluminum lithographic printing plates within the scope of these orders include all aluminum lithographic printing plates, irrespective of the dimensions or thickness of the underlying aluminum substrate, whether the plate requires processing after an image is applied to the plate, whether the plate is ready to be mounted to a press and used in printing operations immediately after an image is applied to the plate, or whether the plate has been exposed to light or heat to create an image on the plate or remains unexposed and is free of any image. Subject merchandise also includes aluminum lithographic printing plates produced from an aluminum sheet coil that has been coated with a light-sensitive image-recording layer in a subject country and that is subsequently unwound and cut to the final dimensions to produce a finished plate in a third country (including the United States), or exposed to light or heat to create an image on the plate in a third country (including in a foreign trade zone within the United States). Excluded from the scope of these orders are lithographic printing plates manufactured using a substrate produced from a material other than aluminum, such as rubber or plastic.
