Handle risographically printed sheets with care. As repeatedly mentioned in this publication, the lack of fixation of the sheets is particularly noticeable during processing, since it stresses the sheets much more than touching and consuming a booklet or book that was printed using a risograph. A clean work environment is just as important as dry and clean fingers. If required, sheets can also be processed further with the use of gloves. Likewise, it should be ensured that, when sheets are folded, they are not necessarily processed further in places with high ink coverage. Using a folding stick on a colour field with a high colour portion can cause the sheets to stain the folding stick. The sheet itself may also become stained. It is important to regularly check the folding stick to make sure it does not absorb any colour during a longer fold.
