RECOMMENDED PROCESSING CAPACITIES
Chemicals must be changed after two weeks in the processor or
after the equivalent of 1000 8x10 inch or 1250 17.8x24 cm
prints have been processed. This is equivalent to 50m
2
(540
square feet) of paper. The table below lists the number of sheets
(rounded to the most appropriate whole number) contained in
one square metre (10˙8 square feet) of paper, and can be used
to calculate throughput when processing a number of different
sizes of paper.
Paper size Paper size Number of
(cm) (inches) sheets in 1m 2
50.8x61 20x24 3
40.6x50.8 16x20 5
30.5x40.6 12x16 8
24x30.5 9x12 14
20.3x25.4 8x10 20
17.8x24 7x9 24
16.5x21.6 6 1/2 x 8 1/2 28
12.7x17.8 5x7 45
8.9x12.7 3 1/2 x 5 89
For example: 3 sheets of 20x24 inch paper is equivalent to 1m 2 .
This means that 150 (3x50) prints can be processed on one fill
of chemicals.
