How Filecheck enforces consistent page dimensions, allowed orientations, and expected page counts for printing.

What is Document Geometry?

Document Geometry refers to the physical layouts, counts, and structural dimensions of an uploaded file. This includes:

Page Size: The width and height of the pages.
Page Count: The total number of pages in the document.
Page Orientation: Portrait, landscape, or square layouts.
Page Rotation: Embedded orientation angles (e.g. 90 or 180-degree rotations).
Imposition Layout: Whether pages are submitted as single pages or side-by-side spreads.

The Print Risk: Incorrect Layouts and Splicing Errors

If document dimensions or page counts do not match order expectations:

Imposition Failure: Automated print layouts expect a standard pagination order (e.g., booklet pages in multiples of 4). If a 15-page PDF is uploaded for a 16-page booklet, the automated prepress system will break.
Wrong Dimensions: Printing a standard letter flyer on a landscape card template stretches or crops graphics incorrectly.
Inconsistent Pages: If page 1 of a booklet is letter-sized but page 2 is postcard-sized, the binding process fails.

Filecheck verifies all physical constraints instantly on ingestion:

Dimension Auditing: We read the layout dimensions of all pages. If sizes differ, Filecheck flags a warning (geom.consistent_page_sizes).
Page Count Mapping: We verify the page count matches the configured order slots (geom.page_count).
Rotation Autofix: If a page contains an embedded rotation flag (e.g., rotated by 90 degrees), Filecheck automatically rotates and normalizes the coordinates to standard portrait or landscape orientations (geom.rotation).
Spread Splitting: If spreads (side-by-side pages) are uploaded where single pages are expected, Filecheck’s workflow builder can automatically split the double spreads into two independent pages.
