Q: When my finisher presses slacks that are constructed with a twill weave (especially gabardine), a discoloration that resembles a swirl occurs. What causes this, and how can it be prevented?
A: This discoloration is sometimes referred to as “moiré.” Using vacuum while the head is in the down or locked position can cause this rippled look to occur. To avoid this problem, activate the vacuum as the head of the press is released.
