Rubber Stamp & Wax Seal Vector Preparation Guide
Creating crisp, high-definition impressions on paper, wedding invitations, product packaging, and wax seals requires strict vector path preparation. When engraving vulcanized rubber sheets, polymer stamps, or CNC milling brass wax seal dies, low-resolution raster images produce blurry edges, fragile ink bridges, and collapsed stamp shoulders.

1. Technical Tolerances for Stamp & Seal Production
| Application | Min Line Width | Min Gap / Counter | Relief Depth | Recommended Format |
|---|---|---|---|---|
| Laser Cut Rubber Stamp | 0.30 mm (0.85 pt) | 0.40 mm (1.15 pt) | 0.9 – 1.2 mm | SVG / PDF (100% Black) |
| Brass Wax Seal Die | 0.35 mm (1.0 pt) | 0.45 mm (1.3 pt) | 1.5 – 2.5 mm | DXF / SVG (Inverted / Mirrored) |
| Photopolymer Plate | 0.25 mm (0.7 pt) | 0.35 mm (1.0 pt) | 0.6 – 0.9 mm | High-DPI PDF / EPS |
| Blind Embossing Seal | 0.40 mm (1.15 pt) | 0.50 mm (1.4 pt) | 0.5 – 0.8 mm | DXF (Male/Female Pair) |
2. Stamp Shoulder & Ramp Angle Optimization
To prevent tall thin stamp characters from bending or distorting when pressed into ink pads, laser engravers use "Shoulder Mode" (or "Ramp Profile"). This generates a trapezoidal tapered base supporting every raised vector character:
- Vector Closed Outlines: The laser software calculates the ramp offset outward from the exact vector perimeter. Crisp vectors ensure the support shoulder never bleeds into adjacent letter counters (like the inside loop of 'e', 'a', or 'o').
- Bridge Clearances: Script signatures and monogram crests require minimum 0.40mm clearance between overlapping flourishes to prevent ink from pooling into a solid black smudge.
- Horizontal Mirroring: For direct rubber stamping and wax seal matrix dies, vectors are mirrored along the vertical axis so the resulting physical impression reads correctly from left to right.
