About this collection

The numerous environmental and economic benefits of light induced chemistry make these technologies popular for manufacturers and fabricators within a wide range of sectors. The European Symposium of Photopolymer Science (ESPS) aims to bring together the brightest minds from both academia and industry to collectively present and discuss the fundamental issues within this still burgeoning field. 
This special issue, guest edited by Dr Kurt Dietliker, Dr Heinz A. Krebs, Prof. Robert Liska and Prof. Marco Sangermano, is based on the recent vESPS conference and is dedicated to Prof. Ewa Andrzejewska, who sadly passed away. She was not only an excellent scientist but was well known for her warm-hearted personality. Her scientific achievements had a strong impact on the development of photopolymer sciences. 
Articles will be added to this collection as soon as they are published. Please revisit this page frequently to read the latest advances in photopolymer science and watch the collection grow.
