Without knowing what kind of press it is, it is hard to give a recommendation as to what torque spec you require, but rest assured, no matter what torque wrench to purchase, you will immediately see a benefit to using one! For most sheetfed presses, use 1 ft/lb per inch of width + 5 ft/lbs. So, a 40" wide printing blanket, would be approx 45 ft/lbs of torque. Web presses, totally different....
In all cases, get your torque specifications from your press manufacturer, or a good blanket technical representative!
