ImageWelcome to Verdigris. This site provides information about environmental initiatives for the international printing community. It has a range of articles and reference links for printers, publishers, technology providers and anyone else who’s interested.

Articles cover all sorts of topics from explaining the basics of carbon footprinting for printers, to describing how individual printing companies are doing their bit to minimise their impact on the envrionment. This is an educational site that includes reference material and links to industry associations and environmental organisations around the world.

LONDON, UK – December 9, 2009 – Sun Chemical, the world’s leading producer of printing inks and pigments, released its first sustainability report, which provides data-driven performance measurement for seven key sustainability metrics to help customers and consumers understand the company’s environmental footprint.

Copenhagen Communiqué Signed by PrintCity Alliance

Gröbenzell, Germany, December 1, 2009 – The PrintCity Alliance has signed the Copenhagen Communiqué on Climate Change, calling for an ambitious, robust and equitable global deal on climate change that responds credibly to the scale and urgency of the crises facing the world today.

Pulp facts

ImagePaper is arguably one of the most useful commodities every invented, one that most of us make use of every day, and yet few people know exactly how paper is manufactured.

Since its invention paper has played an essential role in spreading literacy and knowledge, and despite our modern communications technology it is still irreplaceable. Making paper is a multi-billion dollar industry and part of a major economic sector: the global forest industry employs 13 million people in nearly 200 nations.

The Ultimate Plate

ImageWe’ve seen processless plates, and plates with low chemistry requirements, but what about a CtP plate with no coating or chemistry whatsoever?

Computer to plate production has improved printing’s carbon footprint no end because it does away with film and the associated chemistry. But the recently announced Miracle technology, developed in the UK by JPI, does away with coatings and processing entirely. JPI has patented a method of switching uncoated, grained and anodised aluminium from hydrophilic to hydrophobic states, so they don’t need any coatings at all.

In the wash

ImageDe-inking used paper is a major step towards making recycled paper, but can established de-inking processes keep up with advances in printing technology?

There is a generally accepted principle that it is better to recycle as much paper as we can, rather than cutting down trees to make paper from virgin fibres.
