Define the job and measurement boundary
Check the printer-approved ribbon width, core and winding direction, then measure actual ribbon feed across a representative good-output run.
Estimate running ribbon for one label lane when ribbon advances continuously at the entered repeat. Obtain actual printer feed behaviour before ordering; savings modes change consumption.
Work through the numbers
Run 200 accepted labels, measure the ribbon used, and record startup tails separately. A 10 m use gives 50 mm per good label before other allowances.
Ribbon metres = Good labels × Print repeat / 1,000 / (1 − Loss/100) 10,000 labels at 50 mm pitch and 5% gross loss require 526.316 m.
Whole rolls = ceil(Required metres / (Roll metres − Unusable metres)) 600 m required from 300 m rolls with 5 m unusable per roll needs 3 rolls and leaves 285 m usable surplus.
Consumed ribbon cost/good label = Price × Pitch / (1,000 × Usable roll length × Yield) EUR 12 / 295 usable metres × 0.05 metres / 0.95 = EUR 0.002141 per good label.
Avoid the comparison error
A 50 mm label is not necessarily a 50 mm repeat: include the gap and actual printer feed. Saving modes can make geometric ribbon estimates inaccurate.
- One lane; continuous ribbon advance per repeat.
- Startup leader and fixed tails are separate from this process-loss allowance.
- A single identical ribbon specification.
- Whole-roll surplus is inventory, not automatically process waste.
- Continuous one-lane feed; confirm actual consumption.
- Material allocation differs from whole-roll purchasing cash outlay.
Prepare a comparable purchasing decision
Replace each example with dated measurements and confirmed charges for the same SKU and job. Keep unresolved specification differences visible rather than ranking incompatible offers.
Record the original quote unit, material scope, fixed charges, freight and valid quantity tier. Review an alternative as a separate scenario before adding it to the complete packaging cost.
