## Abstract

A printing apparatus configured to print on the pages of a block of printable pages that are pre-bound by a binding along a binding-edge of each page. The pages of the block are arranged in two interconnected stacks that are joined by the flexible binding. Printing is performed on the top surfaces of each of the stacks, and then a top page is redeployed from one stack to the other. During the redeployment process, the page is turned, thereby revealing an unprinted side of the page. Since the height of each of the stacks changes each time a page is redeployed, the printing apparatus includes two height-adjustable stack support tables each associated with a corresponding one of the two stacks. The support tables are configured to adjust their height so as to maintain the planar relationship of the top surfaces of each of the stacks. After printing, the printed pages are removed separated from the unprinted pages. A book-cover is then attached to the printed pages to complete the book.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The method of claim 1, further including separating printed pages of the printed material from said block.

### Claim 3 (depends on 2)

The method of claim 2, wherein said separating printed pages is accomplished using a cutting element associated with said printing device, said cutting element configured to separate said first stack from said second stack.

### Claim 4 (depends on 1)

The method of claim 1, further including attaching said printed pages of the printed material to a book-cover.

### Claim 5 (depends on 4)

The method of claim 4, wherein said book-cover is implemented as a pre-fabricated adjustable book-cover with an adhesive spine area shielded by at least one peel-off cover section configured to reveal a predetermined adhesive area when removed, such that an area of said adhesive spine corresponding to a size of a binding area of said printed pages of the printed material is revealed for said attaching.

### Claim 6 (depends on 1)

The method of claim 1, further including determining the number of pages redeployed during said redeploying said top page of said second stack to said first stack using a sensor configured to determine the thickness of material redeployed.
