Press Run Waste Calculator

Ordering exactly the number of sheets in your final run quantity almost always leaves you short, because printing loses sheets at three distinct stages, and this calculator adds each one back in. Makeready waste is the paper burned during press setup to dial in registration and color, and it scales directly with ink colors — each additional color needs its own dedicated makeready sheets, so the calculator multiplies your makeready-sheets-per-color input by the number of colors in the job. Running waste is ongoing spoilage during the actual print run — sporadic misfeeds, streaks, minor defects — modeled as a base 2% of run quantity that climbs another half a percentage point for every ink color beyond the first, since more colors mean more chances for something to go slightly wrong on any given sheet.

Finishing waste covers paper lost to folding and binding operations after printing: no folds add nothing, a single fold adds 1% of run quantity, and multi-fold work (gate, roll, Z-fold) adds 2.5%, on top of whatever flat binding waste you enter for trimming and gathering losses. All three waste categories sum to total waste, which is added to your run quantity to get total sheets to order — the number you should actually send to the paper supplier — and waste percentage expresses total waste as a share of that order total. These percentages are industry-typical planning figures based on job complexity, not a guarantee from any specific press or bindery; a well-tuned digital press or an experienced crew can beat these numbers, while a first run on unfamiliar stock can exceed them.
