The Rosette Print Test: Reading the Dot Pattern Under a Loupe
Under magnification, genuine offset printing forms a flower-like 'rosette' pattern; many fakes show a different, grid-like dot structure.
What this checks
Real cards are printed with professional offset presses that lay down CMYK dots in a rosette pattern. Counterfeits often use consumer or digital printing that produces a regular square halftone grid or visible banding instead.
Tools: Loupe or microscope (30–60x)

Genuine looks like
Tiny dots arranged in rotating rosette clusters, smooth color transitions, crisp edges on text.
Fake looks like
A regular square grid of dots, fuzzy or pixelated edges, visible banding, or random noise instead of clean rosettes.
Step by step
- 1Place the card under good, even light.
- 2Hold a 30–60x loupe over a mid-tone area of the artwork.
- 3Focus until individual ink dots are sharp.
- 4Look for rotating rosette clusters (genuine) versus a square grid or noise (suspicious).
- 5Check several areas — text edges are especially revealing.
Why it matters
The printing process is one of the hardest things to fake convincingly. Once you can read a rosette, this is a very strong signal.
