Abstract
Abstract The platen which carries the printing blanket in a dry offset lid printer is formed by a radial milling operation, producing substantially a right conoid configuration in the article engaging part of the platen which feeds the article as it comes into printing position. A proper relation of the elements is automatically obtained.

Claim 1
Independent Claim
141 words
A blanket-carrying platen for dry offset printing in machines handling articles having an upstanding flange around them and substantially a flat surface to be printed, the said platen comprising a substantially cylindrical blanket carrying outer surface which conforms to the outline of the surface to be printed, and a side surface contour parallel to a right conoid surface generated by a line which is in contact with and at right angles to an axis concentric to said cylindrical surface and in which the leading edge of the side surface contour is spaced circumferentially from a radius of said cylindrical surface but parallel to said radius, whereby the said leading edge of the side surface contour is parallel to the common axial plane of a printing cylinder carrying said platen and a cooperating impression cylinder, while still spaced from the printing point.
