Printing plates, which were fixed and developed based on a photographic film, were substituted with a technique called computer to plate – CTP. With this technique, the files are directly transferred from computer files to the aluminium printing plate in a closed system. The developer and fixer have been replaced by a finisher.
Hydrazine is a suspected carcinogen and has been added in 2011 to ECHA’s Candidate List of SVHC for authorisation under REACH.
Alternatives to hydrazine as oxygen scavenger in the treatment of industrial water for boilers are presented with a brief comparison of the main technical advantages/limitations.
A number of methods for chemical substitution specific to the printing industry have been developed and tested. The results of this work are described in a report and have in addition been integrated in a prototype for an electronic tool. This report and particularly the final version of the electronic tool can be a help to the graphic industry, in the process of chemical substitution.
The radiology service of the hospital Parc Taulí, Spain, used several chemical products for fixing and developing X-rays. These products, widely used in hospitals, contain hydroquinone, which is carcinogenic and a neurotoxic and boric acid which is an endocrine disrupter.
In 2004 these products were replaced by a digitized radiography system. This is a display of digital medical imaging for diagnostic use with a range of software called RAIM.
