How do you calculate roll-to-roll output?

Divide completed output by run time for the raw rate, then multiply by line efficiency. With 1200 units over 8 hours at 90% efficiency, the raw rate is 150 per hour and effective output is 135 per hour.

What is a good efficiency for a roll-to-roll printed electronics line?

Well-run continuous lines often sustain 85% to 92% once splices, registration stops and scrap are counted. New processes during ramp can sit well below that until tension and cure are dialed in.

What is the difference between raw and effective roll-to-roll output?

Raw output is completed units divided by run time, ignoring losses. Effective output applies efficiency to strip out downtime and scrap, so it reflects only good product reaching the rewind, which here is 135 versus 150 per hour.

Should efficiency include web breaks and splices?

Yes. Anything that stops the web or produces unusable material belongs in the efficiency figure, including breaks, splice-outs, registration recovery and out-of-spec footage, because they all reduce good output.

How is roll-to-roll output different from batch throughput?

Roll-to-roll runs continuously, so losses accumulate along the web rather than per part. Tension, thermal stretch and splice frequency dominate, which is why a single efficiency term captures the continuous nature better than a discrete yield count.

Can I use this to compare two presses?

Yes, as long as you define run time and efficiency the same way for both. A slower press with high efficiency can beat a fast one that stops frequently, and this calculation surfaces that on the effective-output line.

Printed Electronics & Flexible Hybrid Electronics calculator

Roll-To-Roll Output Calculator

Roll-to-roll output is the effective production rate of a continuous printing line after uptime and yield losses are removed from the raw speed. A press might be rated for a nameplate speed, but web breaks, splices, registration stops and scrap all eat into what actually reaches the rewind as good product. Production managers in printed and flexible hybrid electronics use this metric to plan realistic capacity and to expose the gap between how fast the line can run and how much it truly delivers. It is the number you should quote to customers and use for scheduling.

What this calculator does

Roll-to-roll output is the effective production rate of a continuous printing line after uptime and yield losses are removed from the raw speed.
Use it when roll-to-roll output in printed electronics and flexible hybrid electronics is being committed and you need a throughput number you can defend.
It divides completed output by run time for a raw hourly rate, then multiplies by line efficiency to give the effective good output per hour.

Formula used

Raw roll-to-roll output = completed output ÷ runtime
Effective roll-to-roll output = raw throughput × efficiency

Inputs explained

Web length or units printed per run:
Roll-to-roll run time:
Line efficiency (uptime x yield):

How to use the result

Use it when scheduling roll-to-roll production or committing delivery dates, so your capacity plan reflects real uptime and yield rather than nameplate speed.
A single efficiency figure blends uptime and yield into one number, so it can mask whether losses come from stoppages or from scrap, which require different fixes.

Current U.S. benchmarks

The producer price index for copper and brass mill shapes stands at 559.593 (BLS, May 2026), up 76.8% from a year earlier. Quotes priced off last quarter's material cost miss this move. Global copper trades at $13,484 per tonne (IMF via FRED, May 2026).
The U.S. has 11,261 computer and electronic products establishments employing about 815,443 workers (Census County Business Patterns, 2023).
