PDF Color & Ink Signal Inspector
Upload the PDF to inventory detectable print-color signals before sending it to a full preflight/RIP.
Inventory color-production signals before full output preview
This local inspection looks for readable PDF color-space, spot/separation, output-intent, overprint and transparency evidence. It does not render separations or calculate live TAC.
Color numbers only become meaningful inside an output condition
PDF color-space and output-intent signals help diagnose a job, but browser-side token inspection does not replace a color-managed separation preview or printer-specific preflight.
Color-space, output-intent, spot/separation or overprint tokens that can be read from the file.
Which profile, TAC limit, black build or conversion policy is correct for this output condition.
Use the printer/prepress profile, proofing workflow and professional output preview where the job is color-critical.
What the result is useful for
Useful for quickly spotting obvious RGB/CMYK/spot/output-intent signals and knowing what needs a professional preflight next.
How the calculation works
The browser searches PDF object dictionaries and content tokens locally and reports detected evidence separately from inconclusive/undetectable conditions.
What this calculator cannot know
This is not color-managed rendering, separation preview, TAC heatmapping or proofing. Compressed content and indirect objects can hide signals from a lightweight browser inspection.
