Expectations are normally high and conservators are continuously challenged to acquire innovative techniques and new materials to satisfy this need. One important part of retouching is to use and incorporate materials with long-term durability, but always based on the concept of minimal intervention. The accomplishment of these expectations entails a detailed diagnosis and planning of the treatment with attention to function, to aesthetics and to the stability of the materials. Communication is the key word for a good intervention. Proper communication will not only enhance the conservator– owner relationship but also provide greater acceptance of the treatment planning. The evolution of digital technology has created exciting opportunities for improving this communication process and to facilitate a smooth workflow, from diagnosis to the final treatment and maintenance phase. The International Meetings on Retouching of Cultural Heritage (RECH), initiated in 2013, have gained an international audience, bringing together conservation-restoration professionals, academic members, students and independent researchers from across the world. The conferences aim to promote the exchange of ideas, concepts, terminology, methods, techniques and materials applied during the retouching process in different areas of conservation. This postprints presents the articles of the fourth edition of RECH that took place in Split (Croatia) from October 20th to October 21st, 2017 and was jointly organised by members of the Escola Artística e Profissional Árvore, the Faculty of Fine Arts of the University of Lisbon, the Arts Academy of the University in Split, the Catholic University of Portugal, the Cinábrio and University of Aveiro. The Scientific Committee, consisting of renowned experts 8 9 in the conservation-restoration field, selected 24 abstracts for communications and 16 abstracts for poster sessions, not all publish here. The titles cover a ÍNDEX | COMMUNICATIONS wide range of topics - from digital options for documentation, diagnosis and treatment, to new solutions and materials for filling and retouching of losses. The organizers give their thanks to all the members of the RECH Committees for their diligent work in setting up the programme and to the sponsors for their generous support.
