Use the Label Pitch & Repeat Calculator
Understanding Your Results
The Label Pitch & Repeat Calculator result is an estimating aid for the production question shown above. Interpret the output as a label-converting planning value. Confirm die layout, gaps, side trim, matrix behavior and rewind limits that apply to the actual construction.
How to Use This Calculator
- Gather the job values for Label length and Gap.
- Use dimensions from the approved die line or production specification, not nominal artwork size.
- Select Calculate and interpret the output for Label Pitch & Repeat Calculator.
- Review the calculated layout or yield against die clearance, side trim, rewind and matrix-removal limits.
Formula & Methodology
Pitch / repeat = finished label length in the feed direction + inter-label gap.
Assumptions & Limitations
Use finished label dimensions and the actual converting layout. Die clearance, matrix stripping, liner behavior, registration and side trim can require more material than pure geometry.
Worked Example
For a 3.00 in label in the feed direction with a 0.125 in gap, pitch = 3.00 + 0.125 = 3.125 in.
Common Mistakes
Use the label dimension in the machine direction. The gap is added once per repeat; do not confuse pitch with cross-web spacing or finished label length alone.
Frequently Asked Questions
Which inputs have the biggest effect on the Label Pitch & Repeat Calculator?
Pitch / repeat = finished label length in the feed direction + inter-label gap. The variables named in that relationship are the first values to verify when the result changes unexpectedly.
How should I check this estimate before production?
Use the label dimension in the machine direction. The gap is added once per repeat; do not confuse pitch with cross-web spacing or finished label length alone. Compare the estimate with one completed job using the same units and quantity basis before turning a recurring variance into a shop standard.
What does the Label Pitch & Repeat Calculator result represent?
Calculate label pitch or repeat from the finished feed-direction label length plus the inter-label gap. The displayed methodology explains the calculation basis; use the worked example to check that your units and quantity basis match the job.
What should I verify before using this result for production?
Use finished label dimensions and the actual converting layout. Die clearance, matrix stripping, liner behavior, registration and side trim can require more material than pure geometry. Confirm the entered measurements against the job ticket, equipment limits or supplier data that apply to your plant.
How should I validate the Label Pitch & Repeat Calculator on a repeat job?
Save the estimate with the job ticket, then compare planned web geometry, footage or label yield with the completed roll record. Separate setup, matrix, splice and finishing losses before changing a standard allowance.
