Thread Brand Charts	Verifying thread selections	Production setup

To maintain color consistency:

• Stick to the same thread brands for all production runs.
• Save digital color palettes for each approved design.
• Regularly calibrate machines to ensure color accuracy .

Design Placement

Take these steps to ensure proper design placement:

• Check hoop alignment and starting positions.
• Periodically confirm design centering and logo placement.
• Document any adjustments made during production .

For intricate designs, use intuitive design tools that allow team members to quickly access and verify specifications. This minimizes miscommunication and ensures consistent quality across all production runs .

Final Product Inspection

Final inspection ensures the product meets quality standards before it leaves for shipping. This step connects production monitoring with delivery by confirming that every detail is up to par.

Visual Inspection

Examine the product under proper lighting to check its appearance, cleanliness, and overall alignment.

• Design Integrity: Check that stitching is consistent and patterns are accurate.
• Surface Quality: Look for any dirt, oil stains, or unwanted marks.
• Base Fabric: Make sure there are no wrinkles or puckering around the embroidery.
• Thread Condition: Inspect for loose threads, gaps, or uneven stitching.

Finishing Details

Use this checklist to review finishing touches:

Inspection Area	Quality Standard	Common Issues
Thread Ends	Cleanly cut, secured	Loose ends, fraying
Backing Material	Neatly trimmed	Excess material, rough edges
Surface Texture	Smooth and flat	Bubbling or puckering
Stitch Density	Evenly distributed	Gaps or overlapping

Check both sides to ensure the backing is neatly trimmed and doesn’t compromise garment comfort.

Size Check

Confirm size and placement using these methods:

1. Center Point Verification: Use a ruler to measure from fixed points like seams or edges. For center-aligned designs, fold the garment to ensure equal distances from reference points.
2. Dimension Check: Verify that the measurements match the approved specifications.
3. Placement Accuracy: Ensure the design is positioned correctly in relation to garment features like hems, collars, or pockets. For off-center designs, double-check against the placement guidelines.
