Caps and beanies are staples of UK workwear packs and promotional merchandise, and neither behaves like a polo. A cap front curves in two directions, a seam runs up the middle, and the frame grips only part of a panel that wants to move.
Stitch a flat-garment file across that front and the design drifts. Each pass pushes fabric ahead of the needle, so the far side of the logo ends up out of register and the mark sits off-centre.
We sequence from the centre seam outward and plan the layout so lettering stays off the ridge. The same logo on polos and softshells needs its own flat file: see logo digitising for flat garments or left chest sizing.
Crooked or gapped caps from a logo that sews perfectly on polos point to a flat-garment file on a cap frame: a digitising fault, not an operator fault.
