How do you calculate substrate yield?

Divide rejected sheets by total processed for the reject share; the headline is the complement. With 8 scrapped out of 250, the reject share is 3.2% and the substrate yield is 96.8%.

Is the headline figure scrap or yield?

The headline is the good-sheet YIELD (96.8% here); the scrap share (3.2%) is broken out in its own row, and the gap line compares the yield against your target.

What is a good substrate scrap rate for signage?

Many well-run wide-format and rigid shops hold total substrate scrap under 3 to 5%. At a 3.2% scrap share (96.8% yield) you are in a healthy band, though premium acrylic and specialty stock often justify tighter targets.

How do I read the gap to target?

It is the yield minus the 95% reference target: +1.8 points in the example. Positive means the run beat its good-sheet goal; negative flags a scrap problem.

How can I lower substrate scrap?

Nest layouts to reduce offcuts, print a proof before committing full sheets, control edge handling to prevent delamination, and check flatbed vacuum and blade condition. Track the rate run over run to confirm changes stick.

Substrate yield vs material utilization?

Yield here counts whole sheets that pass or fail. Utilization measures printed area versus sheet area, capturing nesting waste. Use both: a job can have zero scrapped sheets yet poor utilization from bad nesting.

Signage, Displays & Architectural Graphics calculator

Substrate Yield Calculator

Substrate Yield measures how much of your rigid or roll stock survives the process versus how much ends up in the scrap bin as misprints, delamination or cutting defects. Production leads and estimators in sign and display shops track it because substrate, ACM, PVC, acrylic, foamboard, is often the single largest material line on a job. A creeping scrap rate quietly inflates material cost and blows through the media buffer you quoted. This calculator turns a raw defect count into a rate and shows exactly how far you sit from your quality target.

What this calculator does

Substrate Yield measures how much of your rigid or roll stock survives the process versus how much ends up in the scrap bin as misprints, delamination or cutting defects.
Use it when substrate yield in signage, displays and architectural graphics needs a clean rate and gap-to-target you can put on a tier board.
It computes the defect rate as rejected sheets divided by total sheets, then shows the point gap between that rate and your target.

Formula used

Substrate yield = 100 − (rejected or scrapped sheets ÷ total sheets processed × 100)
Reject share = rejected or scrapped sheets ÷ total sheets processed × 100
Gap to target = 100 − (rejected or scrapped sheets ÷ total sheets processed × 100) − target good-sheet rate

Inputs explained

Rejected or scrapped sheets:
Total sheets processed:
Target good-sheet rate:

How to use the result

Use it after a run or shift to gauge material scrap, or during process changes to see whether a new setup improves substrate survival.
It counts sheets equally, so scrapping one large 4x8 ACM panel weighs the same as one small offcut even though the material loss differs.
