Deinking of inkjet at centre stage

Organised by the Centre Technique du Papier in Grenoble the first Technical Conference on deinking of digital prints took place on the 8th and 9th of November in Grenoble. The attractive mountain panorama of the Alps did not detract from the importance and challenges of deinking in today’s graphic arts industry.

Deinking is not only an environmental factor in the production and use of print (as is the total carbon footprint, health and safety at the workplace, and overall usage of resources), it is also an important economic factor for the operators of deinking plants and mills for paper with recycled fibre content. If graphic arts quality paper is to be produced from recovered fibres, certain quality parameters have to be met. While users’ expectations on paper quality are increasing, data from INGEDE (the International Association of the Deinking Industry) shows that the brightness of recovered fibres has been decreasing over the last six years.

With the projected rise of inkjet volumes and potential problems in deinking inkjet prints, inkjet took the centre stage of discussions at the conference. Based on InfoTrends data for 2010, inkjet contributes about 7% of the digital print volume in document printing, with the majority of that share being produced in home and office environments. The overall inkjet share is expected to increase to 13% of all digital production print by 2015, with production printing growing to just under half of that. Large format and packaging & label printing are not included in this view as these prints usually do not enter the waste paper stream for graphic paper recycling. Read more »
