How to Inspect Adidas Trefoil Backpack QC Photos

When viewing Quality Control (QC) photos for the Adidas Trefoil Backpack, pay close attention to the following details:

1. Inspect Logo Embroidery

Examine the Trefoil logo under magnification for stitch consistency, thread tension, and color accuracy. Check for any loose threads, puckering, or misaligned elements that would indicate poor embroidery quality.

Open and close all zippers multiple times to ensure smooth operation without catching. Verify that zipper teeth align properly and that pull tabs are securely attached with correct Adidas branding.

3. Check Stitching Integrity

Inspect all stitching lines, particularly at stress points like shoulder strap attachments and bottom seams. Look for consistent stitch spacing, proper thread tension, and reinforced double stitching where required.
