5. REPLENISHMENT
When operating a processor which uses chemicals for the continuous production of plate/film it is very
important that the chemicals within the machine are keep in good working order so as to provide consistent
processing quality. To achieve this consistency we use replenishment solutions, which are formulated by
the chemical manufacturer and injected into the processor precisely for the area of material being
produced. Replenishment of the chemical tanks is done automatically using infra red sensors located at the
entrance to the processor. These sensors accurately monitor the width of material entering the processor,
this information is in then used by the microprocessor (CPU) control software to calculate the surface area
for each plate loaded into the processor. Each sensor, when covered, will generate a pulse, which is then
recorded on a decoder and counted – the more sensors that are covered then the faster the count. When
the count reaches the programmed value of pulse counts it triggers the start of a replenishment cycle.
During each replenishment cycle the replenishment pumps inject fresh solution from small storage bottles/
tank and into the corresponding ”working” tank solutions for a pre-set time.
