A study has been performed with the purpose of analysing different folding
techniques and its functionality in a climate optimised for digital printing. Coated
papers of stock weight 160g/m2, developed for digital printing, were printed in a
multifunctional copier and folded with different methods. Results show that using
a creasing rule substantially improves the quality. Other factors like folding
method, time from print to fold, fibre orientation and toner layer presented small
variations regarding fold print quality.
The performed study is the start-up of a systematic mapping of folding of digital
prints. Future studies will include a wide range of papers, printers, digital presses
and finishing equipment. The tests will mainly be performed in a climate-
controlled laboratory, giving possibility to analyse folding performance in
different air humidity. The aim is to provide new knowledge about finishing of
digital prints, as well as solutions to existing problems.
