Do you know how to quickly convert your anilox rolls screen-count (cell count) and volume values between metric and imperial unit measurements? You can use these formulas:
For volume:
Volume in cm³/m² = Volume in BCM/in² x 1,55 (*)
Volume in BCM/in² = Volume in cm³/m² ÷ 1,55
(*) 1,54899999999999 rounded to 1,55
For screen-count:
Screen-count in c/cm = Screen-count in cpi ÷ 2,54
Screen-count in cpi = Screen-count in c/cm x 2,54
where:
BCM/in² = Billion Cubic Microns per square inch
cm³/m² = cubic centimeters per square meter
cpi = cells per inch
c/cm = cells per centimeter
Abbreviations and habits:
Volume in imperial expression (BCM/in²) is usually indicated only with the acronym BCM.
Volume in metric expression (cm³/m²) is also indicated as cc/m², or just cc, or -less properly- as grams/m² or even just (and still inproperly) grams, referring to the weight of the dry ink that was transferred, but that’s a different thing.
Screen-count related to anilox rolls is preferably expressed in number of cells (cpi or c/cm) while the reference to lines (lpi or l/cm) is preferably related to plate or printed linescreen.
