Without having specific consumption data by press, there are two approaches
that can be used. Neither one of the methods provide exact consumption data,
but are fairly accurate. I have used them for recordkeeping and permitting
purposes. The first is to develop an ink to fountain solution ratio and if
you know how much ink is used by press, the ratio can be applied.
If ink consumption data by press is not available, then you can approximate
by developing a weighted material consumption average. For each press, you
multiply the total number of impressions, the total number of units, by the
impression size. This results in an arbitrary number. Total all of the
numbers for each press and divide each presses number by the total. this will
provide a relative weighted average in a decimal format. If you want to
express it as a percentage, then multiply the decimal by 100.
Let me know if you have any questions.
