PressLens

Inspect real PDF page boxes, bleed distances, size consistency, color-space signals, output intent, and font-object evidence before production handoff.

Focused field tools

MediaBox

Treat the media boundary as the physical PDF canvas, not automatically the finished size.

TrimBox

Require a deliberate finished boundary and compare it across every production page.

BleedBox

Measure all four sides; one short edge is still a bleed failure.

Art at Bleed

A correct BleedBox does not prove artwork actually extends beyond trim.

Page Consistency

Flag trim-size changes unless mixed finished sizes are explicitly intended.

RGB Signals

Treat DeviceRGB or calibrated RGB tokens as review evidence, not proof of an error.

PressLens reports measurable PDF structure and conservative content signals. It cannot prove visual correctness, trapping, overprint behavior, RIP interpretation, spot-color intent, finishing, or press readiness; review the file in the production workflow.
