Multi-page personalization for a multi-page security document

A multipage security document, comprising:

• a sequence of pages:
• a laser-alterable ink layer placed on a personalization area of an edge of each of the sequence of pages;
• a portion of the personalization area of each of the sequence of pages relative to a page above said each of the sequence of pages is revealed such that a personalization portion of each two consecutive pages in said sequence of pages are located adjacent to one another thereby producing a two-dimensional multi-page personalization section;
• a pattern on the two-dimensional multi-page personalization section created by altering the ink on said personalization area in the revealed portion of each page of said sequence of pages by exposing said revealed portions to a laser, such that the pattern is visible when the revealed portions of a sequence of pages are viewed simultaneously;
• and
• said portion of each page of said sequence of pages is revealed by bending the security document such that for any two adjacent sheets of said personalization zone, a portion of a lower of said two adjacent sheets is exposed beyond an edge of an upper of said two adjacent sheets
• wherein responsive to said bending, said portion of each page of said sequence of pages is revealed as a result of angle-cut edges of the multipage security document such that for any two adjacent sheets of said multi-page personalization section, a portion of a lower sheet of said two adjacent sheets is exposed beyond an edge of an upper sheet of said two adjacent sheets.

A method for personalizing a multipage security document, the method comprising:

• on a sequence of pages:
• placing a laser-alterable ink layer on a personalization area of an edge of each of the sequence of pages, thereby producing an inked personalization area;
• revealing a portion of the personalization area of each of the sequence of pages relative to a page above said each of the sequence of pages such that a personalization portion of each two consecutive pages in said sequence of pages are located adjacent to one another thereby producing a two-dimensional multi-page personalization section;
• creating a pattern on the two-dimensional multi-page personalization section by altering the inked personalization area in the revealed portion of each page of said sequence of pages by exposing said revealed portions to a laser, such that a pattern is visible when the revealed portions of a sequence of pages are viewed simultaneously and
• revealing said portion of each page of said sequence of pages by bending the security document such that for any two adjacent sheets of said personalization zone, a portion of a lower of said two adjacent sheets is exposed beyond an edge of an upper of said two adjacent sheets,
• wherein at least one upper sheet additionally contains an internal cutout window that responsive to said bending reveals an internal portion of a lower sheet such that laser personalization of the upper sheet causes personalization on the lower sheet that corresponds to the personalization of the upper sheet wherein the personalization pattern produced on the lower sheet in a see-through window fits like a puzzle piece into the personalization pattern produced on the upper sheet.
