Remedy
If paper loses moisture and the moisture content has become irregular, the paper may become wavy. Avoid storing paper stock in extremely low humidity environments for a long period of time, unless it is suitably wrapped.
To improve this situation, adjust the settings for <Correct Image for Scratching> to match the specific characteristics of the paper.
