The figures above represent approximately the number of thousand square inches that one pound of ink will cover.
Thus, one pound of offset process blue will cover 355,000 square inches on enamel stock and so on.
Example:
Ink color: Pantone® 185 Red
Ink coverage: 25%
Sheet: Enamel
Sheet size: 24 x 38
Impressions: 20,000
With enamel stock and Pantone® 185 red, the factor for this job will be 350.
Sheet size - 24 x 38 = 912 square inches per sheet side
Square inches x impressions - 912 x 20 = 18,240 total square inches for the job
Total inches divided by factor - 18,240 / 350 = 52 pounds of ink
Ink x ink coverage percentage - 52 x 25% = 13 pounds of ink for the job
