That is why there are medium sheets with two types of overprints. There are also overprints of different sizes (2 or 2.5 mm) on individual letters, as well as on the entire text "waste". Also with "i" instead of "y" in "collect". On sheets (9x10) there are overprints also on the millesima of the sheet - on the left or right.
