Layout Editing Apparatus for Legible Book-Bound Printed Sheets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing layout editing systems for photo albums often result in objects being printed near the fold between pages, making them difficult to read after bookbinding, as they do not adequately consider the booklet binding method and number of pages.
Innovation Solution
A layout editing method and apparatus that determine a layout-inhibited area where objects should not be placed, based on the bookbinding pattern, to prevent objects from being printed at positions that would be obscured or hard to see after binding, using a determination unit to identify this area and a layout unit to position objects accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If objects are laid out near the boundary between continuous pages to maximize usable layout area, then the layout area is increased, but the objects become hard to see after bookbinding
Solution Approach 1:
The page layout is divided into a layout area and a layout-inhibited area (gutter area). The determination unit segments the page by identifying the gutter region near the binding edge based on bookbinding information, creating distinct zones where objects can or cannot be placed. This segmentation ensures objects remain in legible positions while maximizing usable space.
Solution Approach 2:
The system performs preliminary determination of the layout-inhibited area before actual layout placement. By calculating and marking the gutter area in advance based on bookbinding parameters (binding method, number of pages), the layout unit can subsequently place objects only in safe zones, preventing legibility issues before they occur.
2Ease of operation
If layout editing is performed on a spread page basis without considering binding, then editing simplicity is maintained, but objects may be printed on the fold between pages
Solution Approach 1:
The determination unit performs preliminary calculation of the layout-inhibited area based on bookbinding information before the layout unit places objects. This preliminary action incorporates binding constraints into the layout process, ensuring print position accuracy is maintained while preserving the simplicity of spread-page editing.
Solution Approach 2:
The layout-inhibited area acts as an intermediary zone that mediates between the simple spread-page editing interface and the complex bookbinding constraints. By introducing this virtual boundary, the system translates binding requirements into visual guidance without complicating the editing workflow.

AI summary
A layout editing apparatus capable of editing a layout of a plurality of sheets in a layout editing area displayed on a display unit in a case where the plurality of sheets is to be book-bound after being printed includes a determination unit and a layout unit. The determination unit determines, in the layout editing area, a layout-inhibited area where a layout of an object is inhibited, at a position corresponding to a portion at which the plurality of printed sheets is to be bound, with a size according to information about bookbinding. The layout unit lays out the object so as not to overlap with the layout-inhibited area determined by the determination unit.
