The SHADE project has as general objective to generate knowledge to determine which variables of the process are those that exert a greater influence on the tonality of tiles decorated by ink jet, specifically with drop on demand technology (DOD), as well as the actions that must be implemented to be able to manufacture batches with the same tonality. It is also planned to develop a pilot-scale procedure to detect the emission of volatile organic compounds (VOCs) during cooking due to the increasingly frequent presence of organic compounds (additives such as defloculators, binders, etc. and ink solvents) in materials fed to the oven.
