| 1 | Color Accuracy | Require a production sample color difference of ΔE00 ≤ 2.0 against the approved target under consistent measurement conditions. | Measure with a calibrated spectrophotometer using the same illuminant, observer angle, backing, and fabric preparation for every comparison. | Average ΔE00 ≤ 2.0 across measured points, with no unacceptable visual mismatch in the finished garment. | Protects brand color consistency and reduces approval disputes. |
| 2 | Production Sample Control | Evaluate samples made with the intended fabric, print method, ink or dye system, curing process, and production settings. | Request at least 3 samples per colorway from a normal production run rather than relying only on a digital proof. | Color results remain within the agreed tolerance across all submitted samples and major garment panels. | Reveals process variation before bulk manufacturing. |
| 3 | Fabric and Stretch Compatibility | Confirm that the printer can control color on common legging fabrics such as polyester-spandex blends under the required stretch level. | Test the print before and after controlled stretching, covering, and recovery on the actual fabric construction. | No visible cracking, whitening, severe distortion, or unacceptable color shift after repeated stretch-and-recovery checks. | Maintains appearance during wear and movement. |
| 4 | Wash and Rubbing Fastness | Require documented testing for color change, staining, and dry or wet rubbing performance using recognized textile test methods. | Review laboratory reports based on relevant methods such as ISO 105-C06 for washing and ISO 105-X12 for rubbing. | Set a project-specific minimum, commonly around Grade 4 or better where the end-use and color allow. | Reduces fading, staining, and customer complaints. |
| 5 | Print Registration and Coverage | Check alignment, edge sharpness, opacity, gradient smoothness, and coverage across seams, panels, and curved areas. | Inspect the complete garment under consistent lighting and measure or photograph critical registration points. | No visible ghosting, white gaps, banding, pinholes, or misalignment beyond the approved physical sample. | Improves visual quality on fitted, body-contoured garments. |
| 6 | Quality System and Traceability | Select a supplier that records fabric lot, ink or dye batch, machine settings, operator checks, curing conditions, and inspection results. | Request a sample inspection report, calibration record, corrective-action process, and lot-level production documentation. | Every bulk lot can be linked to its approved sample, measurement results, materials, and production date. | Supports root-cause analysis and repeatable reorders. |
| 7 | Capacity, Lead Time, and Reorder Stability | Confirm realistic sampling, bulk production, inspection, and shipping schedules, including the supplier’s ability to reproduce approved colors. | Compare quoted lead times with actual pilot-run performance and review reorder records or controlled repeat-production samples. | The supplier meets the agreed schedule and maintains the approved ΔE00 tolerance during repeat orders. | Prevents launch delays and inconsistent replenishment stock. |
