PDF Preflight Inspector
Select a PDF and InkyValley will inspect readable page-box metadata in your browser without uploading the file.
Inspect print-relevant PDF structure
This lightweight preflight runs in your browser and does not upload the PDF.
Limit: this is not a full PDF/X validator. Compressed object streams, color spaces, embedded fonts, overprint, transparency and separations require a full prepress engine.
What this result means
Useful as a quick preflight before opening a heavier desktop prepress application.
The calculator is designed to turn a print decision into a comparable production value rather than leave you with raw inputs. Use the result to decide whether the file, material choice, page yield, layout or price needs to change before production.
Calculation
The inspector looks for PDF page objects and common MediaBox, CropBox, TrimBox and BleedBox declarations.
If a printer specifies final trim size, bleed, paper category, page yield or a required margin, use that value rather than a convenient round number. Small input differences can matter when a print run is repeated hundreds or thousands of times.
How to use this tool
- Measure or verify the source.Use the actual file dimensions, paper size, quantity, rated yield, job cost or provider specification.
- Enter one consistent set of units.Do not mix inches and millimeters or gross and net costs unless the field explicitly converts them.
- Read the normalized result.Focus on the production value—such as PPI, cost/page, sheets required, full artwork size or gross margin.
- Verify before production.Where a printer, marketplace or machine controls the specification, confirm the current requirement before committing materials.
Limitations
PDF structure can be compressed or encoded in ways a lightweight browser parser cannot fully inspect. An inconclusive result is not proof that a box is absent.
InkyValley separates exact arithmetic from estimates. A mathematically correct result can still be unsuitable if the production process has constraints the calculator cannot observe, such as grain direction, printer margins, ICC profiles, finishing tolerances, maintenance state or provider-specific file checks.
