How do I…
How do I check whether a pattern tiles seamlessly?
Upload the tile. You get a match score and a tiled preview with the seam lines shown. A high score means the edges line up.
How do I check a half-drop or brick repeat?
Switch the layout between Block, Brick and Half Drop. The score is worked out for the layout you choose.
Does checking cost credits?
No. Check a tile as often as you need.

Real-World Examples
Pre-Production QC
Before sending to the rotary printer, a pattern was checked on a 4×4 grid with seam lines on. A 98% match score meant it was ready for production.
Compare Repeat Methods
A floral pattern was tested as Block and as Half Drop. Block showed grid alignment, while Half Drop created a more natural staggered diagonal flow.
