Abstract
A combination master/blanket printing sheet for use with a lithographic offset duplicating press includes a master layer comprising material having hydrophilic properties which is imagable to provide pre-selected oleophilic areas for receipt of printing inks and a blanket layer of hydrophobic-oleophilic material suitable for receiving and carrying thereon an inked image transferred thereto by contact with a member carrying such image. In a preferred embodiment of the printing sheet the master and blanket layers are applied by coating or other suitable techniques to opposite surfaces of a base or support layer. The printing sheet is usable in the offset printing process both as a 'master' sheet, when properly imaged on the master layer, and a 'blanket'.
