DTG versus DTF
DTG may reduce transfer handling and suit qualified garments; DTF can widen placement and substrate options. Film, powder, pressing, storage, pretreatment, humidity, and hand feel shift the balance.
Innovation evidence register
Kornit innovation evaluated as a production method
Innovation becomes useful when a print team can reproduce it. This register turns broad technology language into inputs, measurements, limitations, and acceptance records for DTG and DTF apparel programs.
Structured validation matrix
Translate a technical claim into a repeatable trial
The values below are protocol targets for documenting a test, not published Kornit model specifications. Obtain the selected system data sheet and regional commercial proposal before final approval.
| Question | Controlled input | Observed output | Acceptance evidence |
|---|---|---|---|
| Can the route hold approved color? | Garment lot, artwork, profile, illuminant | Instrument readings and visual grade | Signed reference plus tolerance |
| Does the print survive use? | Recorded pretreatment and cure recipe | Appearance after defined wash cycles | Method, cycle count, photos, grade |
| What is sustained output? | Representative queue and staffing | Completed acceptable units per elapsed hour | Job log including pauses and rework |
| What does the cell consume? | Known jobs and measured run window | Ink, pretreatment, film, powder, energy, rejects | Meter or inventory record with scope |
| How stable is the recipe? | Repeated run after conditioning interval | Color, nozzle status, adhesion, hand feel | Same method, operator notes, retained samples |
Reproducible sample method
- Condition representative garments in the intended production environment and record fiber content, dye behavior, temperature, and relative humidity.
- Print the approved control file while logging pretreatment, print mode, white layer, cure surface temperature, dwell time, and pressure.
- Retain an unwashed control, condition the test sample for the agreed interval, then wash and dry it using the named protocol.
- Evaluate under the agreed light source, record instrument data where available, photograph the same marked areas, and document pass or fail against the pre-agreed threshold.
Readiness checklist
Evidence that should accompany an innovation decision
Facts about standards, safety, ink chemistry, software, and regional support must come from current product and contractual documents. This page does not infer certifications that were not included in the supplied brand assets.
- Configuration identityModel, options, ink set, software and RIP versions, ancillary equipment, and document revision.
- Application boundaryQualified fibers, garment colors, artwork coverage, environmental window, and prohibited materials.
- Method recordSample preparation, pretreatment, cure measurement, conditioning, test standard, and grading rule.
- Operational recordOperator count, complete cycle time, maintenance, changeover, rework, rejects, and downstream labor.
- Commercial recordRegional availability, training, response terms, exclusions, consumables, parts, utilities, and total-cost assumptions.
Technical trade-offs to make explicit
Speed versus cure margin
A faster print stage does not guarantee acceptable output if ink coverage increases drying or curing demand. Measure the complete cell and verify the garment surface temperature.
Automation versus exceptions
Job automation can reduce routine touches, but incorrect metadata, garment picking errors, network interruption, and failed quality checks still require named recovery paths.
Known evaluation limits: results can change with fabric lot, dye migration, optical brighteners, pretreatment deposition, ambient humidity, nozzle condition, artwork coverage, cure equipment calibration, operator loading, and the selected wash protocol. A test on one combination does not establish universal performance.
