Real-World Examples
Pre-Production QC
Before sending to the rotary printer, a pattern was verified at 4x4 grid with seam lines visible. Scored 98% seamlessness — ready for production.
Compare Repeat Methods
A floral pattern was tested in full repeat vs half-drop. Full repeat showed grid alignment, while half-drop created a more natural staggered diagonal flow.
