The 4-Point System is the global standard for grading greige and finished fabric before cutting. Each defect is scored by severity:

• 1 point – minor (e.g., a tiny slub);
• 2 points – noticeable;
• 3 points – significant;
• 4 points – severe (holes, missing yarns), with a single defect capped at 4 points regardless of length.

Points accumulate per roll, and any roll exceeding 40 points per 100 m² (or per 100 yd²) is rejected. This prevents weak, uneven knit from becoming pilling-prone leggings or see-through tops.
