Etablissements Marcel Gandit
This know-how appeared in the 18th century in Bourgoin-Jallieu and has all but disappeared today. The company is responsible for the famous Hermès square, which it developed after meeting the two directors of Hermès in 1948. Today the company is a subsidiary of Hermès and makes screen printed frames for printing "à la Lyonnaise”. This work takes place in two steps. First, the sketches provided by the customers have to be "broken down”. This involves reducing and grouping together the number of colours to meet the technical constraints of the printing techniques, and reproducing, by hand, the drawing reworked on films, with each film corresponding to a colour. Then, the printing frames are made using the photo-engraving principle, with phases of gluing, isolating the photo-sensitive layer and revealing the patterns.
