Abstract
In certain types of printing applications (for example optical or magnetic contact printing) wherein it is desired to transfer imagery from a master device to a replicate device, providing and maintaining close contact between the master device and the replicate device poses certain problems. These problems become even more acute if the surfaces to be contacted are of large area. In accordance with the present invention, close contact over even large areas is obtained between a master device and a replicate device by forming a thin and uniform liquid layer between the master and replicate devices, thus producing a vacuum effect which serves to tightly press the master and replicate devices together.
