Printing and finishing techniques
The product can be used with different printing techniques such as offset, flexo,
rotogravure and digital printing. In digital printing, the product is suitable for several
different sheet- or web-fed presses. Inkjet, dry or liquid toner technology can be used,
although in some cases, pretreatment of the substrate might be required. The latest
certification status can be verified on the press manufacturer’s website or with local
Stora Enso representatives. It is important to check the limitations of the equipment,
particularly because of the exceptional difference in the thickness and stiffness of board
compared with paper in the same grammages. When running thicker substrates, the
press manufacturer’s recommendations should be referred to for optimal grain direction.
Essentially all of the same finishing processes apply to both digitally printed and offset
printed work. Since a wide variety of digital printing equipment is available in the market,
it is important that a new commercial print job is always preceded by a trial run, including
all required printing and converting process phases. The product works very well with
FSC and PEFC certified board available upon request. different finishing techniques, such as embossing, hot foil stamping and others. It is
suitable for laser coding and ink jet marking. Certificates according to PTS-DF 105/2013
and PTS-DF 103/2011 are available upon request.
Storage recommendations
For optimal printing results, the moisture proof wrapping should not be removed until the
board has reached the temperature of the press room.
