How do you calculate good print inspection capacity?

Multiply output per cycle by available cycles for gross capacity, then multiply by uptime and first-pass yield. With 4 units/cycle over 480 cycles at 90% uptime and 97% yield, good capacity is 1,920 x 0.90 x 0.97 = 1,676 units.

What is gross vs. good inspection capacity?

Gross capacity is the raw ceiling — 1,920 units here — before any losses. Good capacity, 1,676 units, is what actually passes once downtime removes 192 units and first-pass yield removes about 52 more.

What is a good first-pass inspection yield?

Well-controlled label inspection often runs 95-99% first-pass yield. The 97% in this example removes roughly 52 units; a yield below 90% signals a print-quality problem upstream, not just an inspection loss.

How much does uptime cost me in inspected units?

At 90% uptime the model loses 192 units off the 1,920 gross — the single largest loss here. Lifting uptime a few points recovers more inspected capacity than chasing small yield gains.

Print inspection sample size vs. verification load?

Sample-size capacity tells you how many good units the inspection step can clear; verification load tells you the hours a specific grading task consumes. One sizes throughput, the other sizes labor time.

Why don't downtime and yield losses simply add up?

They apply in sequence. Uptime derates the gross first, then yield derates what remains, so the yield loss is figured on the post-downtime quantity — which is why it comes to about 52, not 58, units.

Printing, Labels & Industrial Converting calculator

Print Inspection Sample Size Calculator

Print inspection sample-size capacity is the number of good, spec-conforming labels an inspection process can clear once you account for station uptime and first-pass yield. Quality engineers and press QC leads in label and converting operations use it to size how many pieces a shift can actually inspect and pass, not just how many it can scan. Both automated 100% vision inspection and manual sampling stations lose throughput to downtime and to units kicked out on the first pass. Modeling those losses tells you whether your inspection capacity keeps up with press output or becomes the constraint.

What this calculator does

Estimate print inspection sample size for printing, labels and industrial converting using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.
Use it when print inspection sample size in printing, labels and industrial converting is being asked to take on more work and you need to know if there is room.
It multiplies output per cycle by available cycles for gross capacity, then derates by uptime and first-pass yield to give the good, conforming inspected capacity.

Formula used

Gross print inspection sample size capacity = print inspection sample size output per cycle × available print inspection sample size cycles
Good print inspection sample size capacity = gross capacity × expected print inspection sample size uptime × expected print inspection sample size first-pass yield

Inputs explained

Labels inspected per cycle:
Inspection cycles available:
Inspection station uptime:
First-pass inspection yield:

How to use the result

Use it when sizing inspection throughput for a shift or job to confirm the QC step can keep pace with press output and to quantify downtime and yield losses.
It assumes uptime and first-pass yield are stable averages; a mid-shift jam or a defect cluster that spikes rejects will drop actual good capacity below the modeled figure.

Current U.S. benchmarks

The producer price index for paperboard and containers stands at 276.831 (BLS, May 2026), up 8.8% from a year earlier. Quotes priced off last quarter's material cost miss this move.
The U.S. has 22,301 printing and related support establishments employing about 386,248 workers (Census County Business Patterns, 2023).
