INGEDE Actions



European Round Table Deinkability of Digital Prints on October 24 in Bordeaux, following the

Final Conference of the COST Action E46, organised by CTP in Bordeaux, Oct 22–23.


Drupa 2008 has been called "the inkjet drupa" (see e. g. American Printer 8/2007). INGEDE tries to inform publishers and journalists about the problems that inkjet prints create during recycling and why inkjet should be avoided for high volumes such as newspapers and direct mail.

INGEDE published a press release addressing the problems that inkjet prints impose for paper recycling.

A recent press release picks up incorrect claims by HP in environmental brochures distributed at drupa: "Dry toners far better deinkable than liquid toner".


Just discovered: Spare a thought for the paper recycler. An article by Bob Thompson of 1998! Explains nicely already the problems that waterbased create in flotation deinking (and why they create these problems). Only the dry toner part is outdated, these have improved alot since, especially in the production machines.


Inkjet inks and liquid toner are difficult to deink – dry toners do it better

A new technical document by the "Technical Committee Deinking" is in German only as it is a statement of a German committee. One part of it deals with digital printing. The conclusion is a recommendation not to invest into liquid toner or inkjet technologies for production printing unless the deinkability questions have been solved. This document has been agreed upon with the German Printing and Media Industries Federation and other members of the paper chain in Germany who together with INGEDE have set up this "Technical Committee Deinking".

Informal English translation of the German text


Recycling – What can the printing industry do to make it easier?

INTERGRAF, the International Confederation for Printing and Allied Industries, has published a brochure about the "Recycling of Printed Products". INGEDE was not involved in this document. From about p. 29 you find a chapter on interactions with the deinking process. We do not share the opinion on specks from toner based prints, at least not for current production range equipment. This opinion must be based on some more historic SOHO printer based test. What we do share is the opinion on waterbased inks and inkjet inks.

Xeikon includes subject of deinkability into their drupa booth: Video statement

Technische Universtät Darmstadt investigated into the difficulties of removing various types of ink. Dr. Lode Deprez, Vice President Toner & Developer Group Punch Graphix Xeikon, gives "hdm at drupa" the big picture.



  • Ink jet might become the future challenge for deinkers. Among others, Kodak Versamark and IBM are offering high-speed printers for newspapers with ink jet technology. The deinking results are disastrous. On behalf of INGEDE, Axel Fischer addressed this problem in his presentation at the2007 NIP23 International Conference on Digital Printing Technologies in Anchorage, USA: "Digitally Printed Newspapers: Unrecyclable Trash or Still a Sustainable Resource?"
    He chaired a session on Environmental Issues on Friday September 21, 2007:
  • - Environmental Issues and Non-Impact Printing (Focal), Velliyur R. Sankaran, Sankaran Consulting (USA)
    - The Application of High Intensity Ultrasound to the Deinking of Recycled Papers, Robert Thompson, Andrew Manning, and Anna Fricker, University of the Arts London (UK)
    - Austrian Eco Label for Printed Paper Products, Christian Kornherr, Verein für Konsumenteninformation (VKI) (Austria)
    and more. A panel discussion concluded the session.

  • In 2001, INGEDE initiated a program to investigate the recyclability of digital prints. It resulted in a Task Force and a research project, supported by INGEDE and located at the CTP in Grenoble (France). Already the first tests showed that digital printing like Indigo or inkjet means a major problem for recycling – these inks cannot be removed during paper recycling.

  • At a workshop on October 18, 2001, at CTP the problem was discussed with a few representatives of the printer industry. The task force has been formed to monitor developments and investigate parameters that might lead to a better deinkability.

    Summary of the Workshop and more publications

  • INGEDE organises the "European Round Table on the Deinking of Digital Prints" – please contact us for more information! If your business is digital printing equipment (toner, ink, printers), we will be happy if you join the discussion.

  • As a first result, this Round Table has agreed on test files to allow deinkability testing of digital prints with a uniform pattern.

European Cost Action

The EU COST Action E46:
Improvements in the understanding and use of deinking technology


FINAL CONFERENCE

October 22-23, 2008 in Bordeaux/France

COST Action E46: DEINKING

"Improvements in the Understanding and Use of Deinking Technology" 

This conference entitled "Deinking of Graphic Printed Materials: An updated review" is open to everybody interested in "Deinking" and will be held in Bordeaux (Palais des Congrès) during the ATIP Congress.

Organized by CTP, it will involve printing and paper industry representatives.

The objective is to review deinking difficulties related to different types of print and the solutions proposed. Efforts of printers and ink manufacturers to improve the deinkability of their products will be discussed as well as possible adaptations of the deinking process.

Particular focus will be given to results obtained in the framework of the action.

INGEDE (The International Organisation representing all the main EU Deinking Mills) is associated in the organisation of this conference.
