Chocolate Mold Logo Depth: How Deep Is Too Deep for Clean Release
Chocolate mold logo depth - emboss vs deboss limits, Shore A 20-30, release at 12-18 °C, clean demold specs, and RUUIPON food-grade molds at MOQ 50.

Your logo at 1.2 mm deboss looks sharp on screen - in tempered chocolate it traps fat bloom in the corners and sticks on every third demold at 16 °C. RUUIPON builds custom chocolate molds at MOQ 50 with food-grade platinum silicone, prototypes in 3-7 days. This guide sets logo depth limits for clean release without sacrificing brand read.
Quick answer: Deboss logo depth 0.3-0.6 mm for clean release at 12-18 °C; emboss (raised chocolate) 0.4-0.8 mm. Minimum line width 0.6 mm; gap between elements 0.5 mm. Shore A 20-28, 2-3° draft on logo sidewalls, vacuum-degassed pour (~0.1% shrink). Deeper than 0.8 mm deboss needs tapered logo walls or you accept scrap on detailed corners.
Logo Depth Quick Reference
| Logo type | Recommended depth | Max depth (clean release) |
|---|---|---|
| Deboss (recess in mold) | 0.4-0.6 mm | 0.8 mm with 3° draft |
| Emboss (raised on chocolate) | 0.5-0.7 mm | 1.0 mm |
| Fine script | 0.3-0.4 mm | 0.5 mm, 0.8 mm line min |
| Bold block logo | 0.5-0.8 mm | 1.0 mm deboss |
Emboss vs Deboss on Chocolate Molds
Deboss = logo cut into mold face = raised detail on chocolate face (most common for bar molds). Emboss = logo proud on mold = recessed into chocolate - harder to read unless filled with cocoa butter color.
- Deboss - easier demold; chocolate face stays flat on table.
- Emboss - logo wears on contact; depth limited by snap-off of thin chocolate webs.
- Reverse on transfer sheets - not silicone mold topic; different depth rules.

Depth Limits by Line Weight
| Line width | Safe deboss depth | Draft on logo wall | Release risk |
|---|---|---|---|
| 0.5 mm | Not recommended | - | Fill incomplete |
| 0.6-0.8 mm | 0.3-0.4 mm | 3-5° | Moderate |
| 1.0-1.5 mm | 0.4-0.6 mm | 2-3° | Low |
| 2.0 mm+ stroke | 0.6-0.8 mm | 2° | Low |
Gap between logo elements ≥0.5 mm - chocolate bridges snap and leave flecks in mold. Artwork prep: IP & artwork prep.
Shore A & Release Temperature
Softer silicone releases cold chocolate better - but too soft and multi-cavity trays warp in shipping.
| Shore A | Demold temp (chocolate) | Logo depth headroom |
|---|---|---|
| 18-22 | 14-18 °C | +0.2 mm vs table above |
| 22-26 | 12-16 °C | Standard spec |
| 26-30 | 10-14 °C | Reduce depth 0.1-0.2 mm |
| 30+ | Risk stick on deep deboss | Logo ≤0.4 mm only |
Hardness deep dive: Shore A for chocolate. Odor/taste on food trays: odor & taste qualification. Certification: FDA vs LFGB.
Demold Failures on Deep Logos
| Defect | Cause | Fix |
|---|---|---|
| Logo corner stuck | 0.9 mm deboss, 0° draft | Reduce to 0.5 mm + 3° draft |
| Top of letter pulls off | Thin emboss 0.3 mm wide | Widen stroke to 0.8 mm |
| Fat bloom in recess | Deep sharp corners | Radius 0.2 mm on logo root |
| Incomplete fill | 0.4 mm wide × 0.8 mm deep | Shallow depth or wider line |
Wall thickness around logo wells: maintain 2.5-5 mm floor - thin spots curl. Wall thickness. Spacing 8-20 mm on multi-bar sheets.
Master Prep for Logo Fidelity
Logo depth is cut into master - CNC or high-res SLA. Vacuum-degassed silicone pour copies ±0.05 mm on polished master.
- Vector art - STEP/STL with explicit logo depth callout, not PDF alone.
- Master material - CNC PMMA or aluminum for MOQ 50 repeat orders.
- Polish - SPI A-3 on logo face for gloss chocolate; matte bead blast for rustic bar.
- Scale - master +0.1% for silicone shrink. Shrinkage.
Master comparison: master model materials.

Frequently Asked Questions
Can I do 1.5 mm deep logo for premium look?
Not on standard bar demold - use tapered cavity or accept 15-25% corner stick scrap.
Emboss or deboss for photography?
Deboss 0.5 mm reads best on flat bar face for e-commerce shots.
White chocolate vs dark - same depth?
Same mold; white fat bloom shows more in deep corners - favor shallow depth.
Polycarbonate vs silicone depth?
PC allows sharper vertical walls; silicone needs draft - do not copy PC depth 1:1.
MOQ with logo?
MOQ 50 pieces per design - logo included in mold cost.
Sample approval?
Sample checklist - send photos of 5 consecutive demolds.
Cycle life on logo corners?
Deep logos stress corners - 500-2000 cycles typical at Shore A 24. Cycle life.
