Add bleed margins to a PDF for commercial print shops that trim — extends the page size by the bleed amount on each side and shifts content to the new center. Most office digital printing does NOT need this; use only when sending to a print shop. Triggers on phrases like "add bleed", "add 3mm bleed", "prep for trim".
Generate a matching-size cover page with a title (and optional subtitle, author, date) and prepend it to a PDF. Triggers on phrases like "add a cover page", "prepend a title page", "make a cover for this PDF".
Overlay a diagonal text watermark (DRAFT, PRIVATE, CONFIDENTIAL, etc.) at 45° across every page in light red (or user-specified color), at low opacity so body text remains readable. Triggers on phrases like "add a DRAFT watermark", "stamp PRIVATE on every page", "watermark this PDF".
Burn a permanent footer label into every page of a PDF — CLIENT CONFIDENTIAL, PRIVATE, FAMILY DISTRIBUTION, DRAFT, EMBARGOED UNTIL ..., or custom text. User can choose font and size. Renders a PNG preview to verify layout before committing. Triggers on phrases like "add a CONFIDENTIAL footer", "burn in a footer", "stamp 'embargoed until' across the bottom".
Convert a color PDF to grayscale (black-and-white) for monochrome digital printing — saves toner and avoids color-mismatch issues. Triggers on phrases like "convert PDF to grayscale", "make it black and white", "remove color from PDF", "monochrome PDF".
Bundle one or more print-ready PDFs into a single "print job" folder with a manifest, ready to hand to a digital printer or share with collaborators. Triggers on phrases like "create a print job", "bundle these PDFs", "make a job folder for the printer".

Convert transparent overlays, alpha blends, and soft masks into solid raster/vector output. Many digital printers (especially older RIPs or budget office units) mishandle live transparency, causing banding or color shifts.
print (default, 300 DPI raster regions), screen (150 DPI, smaller files), prepress (highest fidelity).<input>-flat.pdf.Ghostscript with pdfwrite and -dCompatibilityLevel=1.3 flattens automatically because PDF 1.3 has no live transparency model.
gs -o output.pdf \
-sDEVICE=pdfwrite \
-dCompatibilityLevel=1.3 \

Compatibility=1.3 forces flattening. /printer tunes raster quality for print.
Symptoms that suggest transparency is the culprit:
Probe for transparency:
mutool show input.pdf grep -i "/SMask\|/CA\|/ca\b\|/BM"
Hits → live transparency present.
Flattened PDF. Original preserved — flattening is destructive in the sense that liveness is lost.
