ABSTRACT The method disclosed is one wherein n pumps and n relative solenoid valves operated by a single microprocessor controll- ed stepping motor dispense one or more of n colouring agents into a paint/varnish medium. The quantity dispensed is either a proper of improper fraction of an integer of 1/m of the volumetric unit of measure (fluid oz) and is defined p, a nominal value reflecting the number of half-steps indexed by the mdor which is corrected proportionally by comparison of the effective and the nominal weight of a droplet downstream of the pump and upstream of the solenoid valve in order to produce an effective number of half-steps x. A similar correct- ion is made to the number R of half steps which correspond to the delay occasioned by operation of the solenoid valve, comparing the effective and-nominal weights of the droplet downstream of the valve; the speed of the motor is corrected to compensate for system resistances. The machine comprises a single motor (26) operating the n pumps (25) which dispense colouring agent from n relative containers (16) by way of n nozzles (8) located above a vertically-mobile platform (4) on which the container (2/3) with the medium is placed, its position controlled by a photocell (15). All of these components are housed in a cabinet comprising a basic framework (1) the top surface of which accommodates a computer (22-23-24) with circuit boards controlling operation of the machine according to the method as disclosed; data is displayed by video and documented by a printer.
