Abstract
An ink jet printing system has a low aspect ratio cylindrical drum adapted to support a sheet of material to be printed by a computer controlled printing head of a plurality of pigmented inks. The drum is preferably of approximately the same diameter as its axial length, is made up of at least two spoked wheel assemblies consisting of several arcuate wheel segment subassemblies that are joined together and held in place by a corregated skin covered with a fiberglass layup to provide a smooth cylindrical surface onto which the sheet material is spread. A clamping device is provided for tensioning the sheet material as it is rotated past a carriage carrying the printing head and affording two relative movement directions as between the printing head and the sheet to be printed for these differently colored printing inks.
