01The repeat
The pattern repeat is the vertical distance before the design starts again. Every drop must begin at the same point in the pattern, so each cut is rounded up to a whole repeat. Larger repeats mean more waste per drop.
02The three match types
| Match | How it lines up | Extra paper per drop |
|---|---|---|
| Random / free match | Any position works; usually stripes or textures | None beyond trimming |
| Straight match | The motif meets at the same height on every drop | Up to one repeat |
| Half-drop (offset) | Every other drop is shifted down by half a repeat | About half a repeat more than a straight match, on average |
03Lining up a half-drop
- 1.Hang drop 1 with the motif where you want it at the ceiling.
- 2.Hold the roll against drop 1 and slide it down until the pattern meets across the seam. The motif will sit half a repeat lower.
- 3.Cut drop 2 from that point. Drop 3 will match drop 1 again, so cutting drops in pairs from two rolls can reduce waste.
TipLabels often use symbols: an arrow with a number (repeat), and arrows at the same level (straight) or offset (half-drop). If unsure, ask the supplier before you cut.
