The RECH Group born during the PhD investigations of the conservator-restorer Ana Bailão in 2013 about chromatic reintegration. After that other researchers join the cause helping the growth up of the initial idea. Most of them help in the organization of the RECH Meetings and workshops.

The Conferences are biannual to provide conservators time to present interesting projects. After three editions of the International Meeting on Retouching of Cultural Heritage in Porto, Portugal, the 4th edition in Split, Croatia, and the 5th edition in Università degli Studi di Urbino "Carlo Bo", in Italy, the RECH6, this year will take place virtually on 4th and 5th November 2021 RECH6 is a collaboration with the Instituto Universitario de Restauración del Patrimonio (IRP) of the Polytechnic University of Valencia, Spain. This year is in Portugal and is hosted by the Faculty of Fine Arts, University of Lisbon.

The results of each conference are published in the Conference Postprints, which constitute an important contribution for the study and improvement of the information about the retouching practice.

The Conference brings useful reports and reviews of retouching projects in current research. About 100 papers have been published in the Conference Postprints in the last three years.
