Patent ID: 7789578

Claim:
A method for producing printed material, the method comprising: (a) providing a block configured from a plurality of blank pages that are pre-bound by a binding along a binding-edge of each page; (b) providing a first block support table and a second block support table, a height of the first block support table relative to the second block support table being adjustable; (c) arranging said block so as to form two adjacent stacks interconnected by said binding, such that at least one of a plurality of the printable pages is deployed in a first stack on the first block support table and a remainder of said plurality of the printable pages is deployed in a second stack on the second block support table, and printable top surfaces of said first stack and said second stack are co-planar; (d) generating relative movement between a printing device and said printable top surfaces so as to print on said top surface of at least one of said first stack and said second stack; (e) redeploying a top page of said second stack to said first stack so as to produce new said printable top surfaces; (f) adjusting a height of each of said first stack relative to said second stack subsequent to each said redeploying said top page of said second stack to said first stack so as to so as to maintain co-planar printable top surfaces of said first stack and said second stack, using at least one sensor to align the top surfaces of the stacks; and (g) repeating steps (d) through (f) as required to print a number of pages required.
