Data-backed appearance control
Appearance Consistency Backed by Measured Data
The provided data includes both black-speck distribution and color variation, so teams can review appearance risk before full production qualification.
Appearance checkpoints from provided data (380 cm² observation area)
| Black speck size range | Count observed |
|---|---|
| ≥ 0.30 mm | 0 |
| 0.20 - 0.30 mm | 0 |
| 0.12 - 0.20 mm | 0 |
| 0.08 - 0.12 mm | 5 |
| Color variation (CIEL*a*b) | Unit | Value |
|---|---|---|
| L* | (+/-) | 75.57 |
| A* | (+/-) | -2.61 |
| B* | (+/-) | 11.29 |
| Judgement range | ΔE* | 0 |
Using property and appearance checkpoints together helps teams move from first trial to production qualification with clearer pass/fail criteria.
