A4 FLATBED SCANNER · WHOLESALE LAB PRE-GRADING
Multi-Card Batch Scan (A4 Grid)
Arrange up to 9 cards (3x3 grid) on your flatbed scanner. Upload front and back scans in 600–1200 DPI – the system automatically crops each card, pairs fronts with mirrored backs, and evaluates the entire sheet at once.
1. Glass Layout
Arrange cards row-by-row starting from the top-left (Row 1: cards 1, 2, 3; Row 2: 4, 5, 6...). Leave ~5-10 mm of spacing between cards against a dark backing lid.
2. Flipping Reverse
Flip the cards onto their backs in the same positions. Our algorithm automatically flips the horizontal X-axis to match each card with its exact reverse side.
3. Instant Triage (PSA 10)
Instantly rank the entire batch to see which cards are viable candidates for submission and which have disqualifying flaws.
