To calculate flatness/parallelism, divide diagonal of die set by 12''. Then multiply by value indicated above. (Example : 48'' diagonal divided by 12'' = (4). (4) x .001'' = .004'' TIR (flat or parallel). NOTE: -Plates greater than 120'' diagonal or less than 1.25'' thick calculated upon application
