The difference between stamps and stickers is in the placement. Stamps are an estimate because you do not have a direct observation of how the stamp is making an impression on the paper. People functioning within ACL 4 High are more likely to be aware of the orientation of the stamps. They are also more likely to not contaminate the stamps by not cleaning the stamps before changing the color. Having two sets of ink pads, one set for ACL 4 Low and another set for people functioning in ACL 4 High helps reduce having muddied stamps for the group who will care.
