Scenario value of Add Border in print
`print-margin-border` supports 打印出血安全场景. Keep border weight, readability, and destination consistency stable with pilot validation, staged rollout, and anomaly logging.
`print-margin-border`: collect bleed mm + minimum line weight, map live size to pixel padding, name `_print` presets explicitly
- No guessing margins: obtain bleed, inner safe, RGB tolerance, and minimum printable stroke (often thicker than on screen). Draw two guides—blade line vs “never cross” type box—and align tool padding to the inner box, not the pretty outer silhouette.
- Hairlines die on toner and digital presses—prefer filled bars at vendor minimums and zoom RIP previews. Large “rich black” frames may brown on sheet; confirm pure K vs four-color builds with the shop and keep a signed proof, not a Slack thumbs-up.
- Landscape lightboxes and vertical pull-ups cannot share stretched masters—rebuild rails per aspect with millimeter-consistent stroke. Ship PDF legends showing trim; never email the sRGB social preview as the press file.
Print margin FAQ: bleed vs safe, broken strokes, warm blacks, dual aspect, screen handoffs
The vendor says “add a little bleed”—is 2 mm or 5 mm the safe default before QR codes vanish?
Demand written bleed and separate safe zones; bleed is meant to be cut away, safe is where QR and signatures live. If they collapse the terms, inset live art further and archive the email—disputes get expensive when specs were verbal.
0.5 pt strokes look elegant on screen but print dashed—file bug or hardware floor?
Usually below the stable line width—raise to the documented minimum or simulate lines with rectangles. If breaks persist, suspect moiré from halftone angles misread as gaps; darken one step or thicken until continuous at arm’s length on A4.
RGB pure black frames warm gray-brown on press—did we export wrong?
Four-color blacks often warm on paper—that’s ink physics, not a mistaken upload. Agree on pure K vs rich black with ΔE tolerance in the SOW. The border tool doesn’t manage ICC; teams must split “screen comp” from “press PDF” workflows.
Can we stretch one framed master between landscape and vertical large-format prints?
Stretching skews corner join weights and shifts safe zones relative to heroes. Rebuild per orientation with millimeter-consistent rules; share colors and type, not warped rasters.
Marketing needs phone previews today but the shop replies about bleed in two days—can we ship screen presets meanwhile?
Yes, if folders and emails scream `_screen_sRGB — NOT FOR PRESS` and you replace the bundle once specs land. The classic failure mode is ops forwarding the preview PNG to a cutter—budget that risk before “temporary” becomes permanent.
