Abstract: A method and apparatus for registering the halftone color separation films used in color picture processing. A digital picture is taken of two register points on each separation film, and the pictures (which may contain register marks) are analyzed by algorithmic processes in order to calculate the movement necessary to register the halftone picture details (or register marks). Based on the calculations, the films are punched to provide a pair of register holes in each film at locations which result in registration when the register holes are aligned on register pins during the final reproduction process. The algorithmic process involves determining the halftone screen angle, average interdot spacing and fractional area occupied by each halftone dot within its halftone cell and using this data to construct a continuous tone picture. Interpolation techniques are used to interpolate the continuous tone picture to a registration picture which is a 150 line screen picture square with the raw data picture.

Abstract: The disclosed cutting method and apparatus produces a pattern cut in web material by providing a generally conically-shaped rotatable anvil and oppositely disposed knife edge shaped to produce the pattern cut. The axes of symmetry containing the apex of the cone is positioned at an acute angle to the axes about which the cone is rotated. With the web positioned over the knife, the knife is brought into pressure engagement with the anvil thereby piercing the web substantially at a point. Rotation of the anvil effects progressive cutting as the anvil surface traces the cutting edge of the knife.

Markings for different paper lengths may be permanently displayed on the platen at an edge of the window. Markings on the platen may be affixed by applying thereto a decal having paper length markings thereon.
