Quality Management

Shenzhen Xingwei Color Printing & Packaging Co., Ltd. has established a systematic, standardized, and traceable quality management system to ensure that mass production strictly follows approved samples and consistently meets customer requirements.

Color consistency is the core indicator of printing quality. We implement a strict color control procedure to ensure that bulk production matches the approved sample.

• Customer-approved samples are used as the only color reference standard.
• Unified paper batches and ink specifications are applied for mass production.
• Color parameters are set before printing and monitored during production.
• First article confirmation is conducted before full-scale printing.
• In-process sampling inspections ensure color density, hue, and registration stability.
• Historical color data can be retained for repeat orders, ensuring long-term color consistency.

To reduce procurement risks, we strictly follow a "sample approval before mass production" principle.

• Artwork review and technical feasibility assessment.
• Digital proof or printed sample preparation based on product requirements.
• Internal quality verification for color, structure, and finishing.
• Sample submission for customer confirmation.
• Sample archiving as the production reference for bulk orders.

We operate a complete quality inspection system covering incoming materials, production processes, and final shipment.

IQC – Incoming Quality Control

• Inspection of paper thickness, grammage, surface treatment, and batch consistency.
• Verification of inks and auxiliary materials.
• Non-conforming materials are rejected before entering production.

IPQC – In-Process Quality Control

• Continuous inspection of color consistency, registration accuracy, and print clarity.
• Monitoring of post-press processes such as lamination, hot stamping, UV, die-cutting, and binding.
• Immediate adjustment and corrective actions when abnormalities are detected.

OQC – Outgoing Quality Control

• Final inspection of appearance, color accuracy, dimensions, and finishing quality.
• Sampling or full inspection based on order requirements.
• Shipment approval only after meeting confirmed specifications.

To reduce human dependency and ensure reproducibility, we apply a structured color management approach.

• Regular calibration and maintenance of printing equipment.
• Standardized color control parameters across different machines.
• Process-based color adjustment instead of experience-based operation.
• Color data archiving for stable repeat orders.

We provide documented quality and compliance support based on customer and market requirements.

• Paper material test reports are available upon request.
• Environmental documentation for printing inks and materials.
• Support for customer audits, factory inspections, and export compliance requirements.
• Documentation aligned with the safety and environmental expectations of international markets.
