Abstract
A reversible printing blanket to be used with offset printing machines. The reversible printing blanket has two opposing lithographic printing faces. The blanket comprises a first external lithographic layer providing a first printing face, a second external lithographic layer providing a second printing face, and at least one compressible layer between the lithographic layers. Such reversible printing blanket allows impressions to be made by both sides of the blanket in such a way as to permit two separate printing jobs.
Claims26
A reversible printing blanket having two opposing lithographic printing faces, the blanket comprising a first external lithographic layer, a second external lithographic layer, and at least one compressible layer between said lithographic layers, wherein each of said first and second external lithographic layers has a thickness of from about 0.1 to about 0.4 mm thereby rendering each of said first and second external lithographic layers capable of providing a printing face that permits impressions to be made on a substrate.
A method for using a reversible printing blanket in offset printing comprising the steps of:
- providing a printing blanket onto a printing cylinder, said printing blanket comprising a first external lithographic layer, a second external lithographic layer, and at least one compressible layer between said lithographic layers, wherein each of said first and second external lithographic layers have a thickness of from about 0.1 to about 0.4 mm thereby rendering each of said first and second external lithographic layers capable of providing a printing face that permits impressions to be made on a substrate, said second external lithographic layer being adjacent to said cylinder thereby defining a first position;
- transferring an image from said first printing face of said first external lithographic layer to a first type of substrate;
- flipping said printing blanket over such that said first external lithographic layer is adjacent to said cylinder thereby defining a second position;
- and
- transferring an image from said second printing face of said second external lithographic layer to a second type of substrate.
