Cost per print is an estimate, not a printer constant
Ink use changes with print area, coverage, color mix, profiles, cleaning cycles and wasted prints. Paper cost is easier, but sheet utilization and test prints still matter. The most useful number is a documented estimate that you replace with observed shop data over time.
Define what “one print” means
Choose a unit that matches the pricing sheet: one mug wrap, one small chest design, one letter-size full sheet or another repeatable transfer. A printer page, a cut design and a finished product are not automatically the same unit. Write down the paper size, approximate coverage, quality setting and whether multiple designs are nested on one sheet.
Conventional dye-sublimation also needs a compatible product. Epson’s maker guidance describes polyester fabrics and hard goods with a polyester coating as compatible surfaces. The transfer-cost estimate does not prove that an untested blank or garment will produce a sellable result.
A practical starting method
- Record the delivered cost and usable amount of your ink set and paper pack.
- Choose one repeatable product or print size.
- Track the number of saleable transfers produced between ink purchases, including cleaning and test use.
- Divide actual spend by saleable output, then add the paper used for one transfer.
- Review the estimate after another full ink cycle.
ink cost per usable transfer = ink consumed during the measurement cycle ÷ usable transfers produced
Count ink consumed by production, nozzle checks, cleaning and failed prints inside the measurement boundary. Count only transfers usable for the defined production class in the denominator. The detailed ink replacement-cycle guide provides a log structure and explains how to separate design classes.
When you do not have observed yield yet
Use a cautious editable estimate and label it as an assumption. Epson’s SureColor F170 specifications state that bottle yield varies considerably with images, settings, paper, frequency of use and temperature, and that part of the first ink supply is used to prime the printer. Manufacturer statements are useful for planning, but they are not a promise that every shop will print the same number of sellable transfers.
Do not use the printer’s first fill as a normal replacement-cycle benchmark unless the initial priming use is identified separately. Replace the assumption after a full, representative cycle. A short test run can reveal a gross error, but it may not capture maintenance ink or the shop’s normal mix of designs.
Paper cost
Paper cost per transfer = delivered pack cost ÷ usable transfers from the pack
If two small designs fit reliably on one sheet, use the number of usable transfers rather than the number of sheets. Include sheets lost to tests, head alignment or obvious print defects in your observed yield.
Worked example: one defined transfer class
Suppose a documented replacement cycle consumes $78.00 of ink and produces 260 usable transfers in the chosen design class. A delivered $24.00 paper pack produces 92 usable transfers after test and damaged sheets are excluded.
- Ink per usable transfer:
$78.00 ÷ 260 = $0.30. - Paper per usable transfer:
$24.00 ÷ 92 = $0.260869. - Combined ink and paper:
$0.30 + $0.260869 = $0.560869, displayed as about $0.56.
The numbers are illustrative shop records, not a yield claim for a printer, ink or design. Keep full precision in the pricing calculation and round only the displayed result. If tape or protective paper is material to the job, record it as another transfer consumable or a separate direct-material input, but not both.
Keep the estimate proportional
A mug wrap and a full-shirt print should not automatically share one ink-and-paper value. Maintain a few size presets you genuinely use. Avoid a complex square-inch model unless it makes your records more accurate rather than merely more detailed.
| Change | Action |
|---|---|
| New paper size or supplier | Start a new paper-yield record with delivered cost. |
| Much larger or denser design | Create a separate print class rather than scaling blindly. |
| New printer, ink or profile | Begin a new measurement cycle and label the transition. |
| More cleaning or failed prints | Keep the consumption in the cycle and investigate the cause. |
Transfer cost is not finished-product cost
After measuring ink and paper, add the compatible blank, product-stage failure allowance, setup and active labor, equipment, overhead, packaging, selling fees and any absorbed delivery cost. For product-specific examples, see the sublimation mug cost breakdown and sublimation shirt cost breakdown.
A transfer that prints correctly can still become a failed product during alignment or pressing. Keep print-stage and product-stage losses separate if that distinction changes decisions; otherwise use one cautious failure field and document what it covers. The waste-rate guide compares flat and stage-specific methods.
Save and review the measurement
Record the cycle dates, invoices, ink or cartridge set, printer, paper, settings, design class, tests, failed prints and usable output. The IRS recordkeeping guidance recommends supporting documents that identify the payee, amount, date and business purpose. It does not prescribe this allocation method, but the same purchase evidence makes an internal cost estimate traceable.
Review after another full cycle and whenever the printer, ink, paper, profile or normal design mix changes. If observed cycles differ materially, use a cautious rolling average or separate classes rather than selecting the lowest result.
