A process for manufacturing ceramic tiles by ceramic powder pressing in cavities of a die provided with an isostatic punch a membrane of which rests on oil contained in adjacent and non-communicating chambers in continuous operation, characterised in that it comprises following operations: detection of a density of the powders pressed in a plurality of points n uniformly distributed in each area of a tile which plurality of points corresponds to a chamber of of the punch; performing a calculation of a mean of density readings taken at all the points in each area; comparing read values with a desired optimal density value; removing or, respectively, adding oil to each isostatic chamber of the punch if the mean of densities in the chamber is above or respectively below the optimal density value.
