01 / THE PROOFLENS PLATFORM
A sharper eye for
your printed work.
Keep the approved file as your point of truth. The ProofLens blueprint connects artwork comparison, difference review and inspection records in one focused workspace.
Product blueprintText difference review
Focus on missing characters and changed copy, with OCR-assisted review included in the product blueprint for critical text regions.
COPY IN CONTEXTBarcode & code checks
Review visible code changes and damaged areas. The product blueprint also covers comparison of decoded content with its reference.
CODE CONSISTENCYAlignment & visual review
Align scanned samples before comparison. Overlay and side-by-side views make possible registration shifts easier to assess.
MAKE DIFFERENCES VISIBLEInspection your way
Define inspection regions and mask intentional variation, such as batch fields. Set tolerances for each job’s review needs.
FOCUSED ON WHAT MATTERSA record of every review
Build a clear inspection record with annotated differences, reviewer decisions and reference files for the quality handover.
EVIDENCE FOR THE TEAMProduct blueprint — see the venture snapshot for the current stage. Code review is not standards-based barcode grading; colour review is not calibrated colour measurement.
