Quality control
Printing & Packaging Quality Control
Much Printing integrates color management, engineering review, laboratory equipment, humidity control and production-stage inspection.
Quality workflow
Control begins with an approved requirement
The appropriate checks depend on the product, material, construction and customer specification.
- 01
Specification review
Confirm artwork, structure, components and quality requirements before production.
- 02
Proof and sample review
Use digital proofing and engineering samples to review key visual and structural requirements.
- 03
In-process control
Monitor printing, finishing, conversion and assembly against approved references.
- 04
Relevant testing
Use documented laboratory equipment for applicable paper-product performance checks.
- 05
Final inspection
Check product appearance, components and packing before release.
Inspection framework
Checks selected for the approved product requirement
Applicable methods and acceptance criteria must be agreed for each project. The following table describes the documented review areas without implying that every test applies to every product.
| Review area | What can be checked | Buyer input required |
|---|---|---|
| Color review | Printed color against an approved proof or defined reference | Reference and viewing expectation |
| Bursting | Relevant paper or board resistance using documented equipment | Applicable method and acceptance criterion |
| Abrasion / rub | Printed or finished surface response to the agreed test | Surface, method and acceptance criterion |
| Compression | Relevant packaging response to the agreed compression check | Pack condition and test requirement |
| Humidity monitoring | Paper handling conditions in the dedicated monitored room | Any project-specific conditioning requirement |
| Final inspection | Appearance, dimensions, components and packing configuration | Approved specification and inspection scope |
Laboratory
Documented paper-product testing equipment
Our laboratory includes equipment for several physical and surface-related tests. Applicable test methods and acceptance criteria should be agreed for each project.
- Puncture testing
- Abrasion testing
- Bursting-strength testing
- Compression testing
- Color-rub or decolorization testing
- Sample preparation and cutting
Paper handling
Temperature and humidity monitoring
A dedicated dehumidification room helps reduce the risk of paper deformation, particularly for card products.
- Dedicated room for controlled paper storage
- Temperature and humidity monitoring
- Relevant to card and paper product stability
- Final conditions reviewed against the project requirement
Color management
Proofing and printing control
GMI color management supports controlled color review. The prepress and printing departments also document digital proofing and multi-color offset printing equipment.
Define quality requirements before quotation
Include any required test method, acceptance standard, color reference, inspection level or packaging test in the inquiry. Do not assume a test automatically applies to every product.
