INKA SUPPORT
How can we help you?
Practical answers to prepare artwork, make successful transfers and maintain your INKA printer.
Getting started
How does DTF printing work?
Your INKA printer prints the design onto transfer film, using colour and white according to the selected mode. Adhesive powder is applied and melted before the design is transferred to fabric with a heat press.
Validate each stage on a sample before starting a production run.
Link to this answerWhat is the difference between textile DTF and UV DTF?
Textile DTF uses hot-melt powder and a heat press to decorate compatible garments. UV DTF uses UV-cured inks and adhesive transfer films for compatible objects.
The inks, films and application methods of these two INKA ranges are not interchangeable.
Link to this answerWhich fabrics can I apply my transfers to?
Cotton, polyester and many blends can accept a suitable DTF transfer. Fibre type is not the only factor: water-repellent finishes, stretch and heat sensitivity can affect the result.
For nylon, coated garments or a new batch, test adhesion, appearance and washing with the consumables selected for your INKA workshop.
Link to this answerWhat do I need alongside my INKA printer?
You need a compatible computer and RIP, DTF inks, film and powder, a powdering station, suitable curing equipment and a heat press. Include the maintenance supplies specified for the machine and suitable workstation ventilation.
Check “In the box” on your model page: included equipment varies by configuration.
Link to this answerDoes a garment need pretreatment before a DTF transfer?
Textile DTF generally does not require the liquid pretreatment used for direct-to-garment printing. The garment still needs to be clean and suitable for the transfer.
Prepressing can remove creases and moisture where the transfer instructions and fabric allow it. It does not replace a compatibility test.
Link to this answerArtwork & RIP software
Which file format and resolution should I use?
Use a format supported by your RIP, such as a transparent PNG or a correctly prepared PDF. For raster artwork, aim for 300 pixels per inch at final size; enlarging a small image does not restore detail.
For logos and text, prefer vector elements and check fonts, dimensions and fine lines in the preview.
Link to this answerWhy is there a white rectangle around my design?
Check that the file background is truly transparent: a white background in a JPG is still part of the image. In the RIP, also check whether white is generated for the design or its entire rectangular boundary.
Preview the white layer separately before printing. Correct the artwork or underbase mode rather than trying to hide the defect during pressing.
Link to this answerShould I mirror the design before printing?
Yes, for the usual textile DTF transfer process. Check mirroring in the final RIP preview, especially with text or an asymmetric logo.
If the artwork was already reversed in your design software, do not mirror it a second time. Make a small test transfer before a run of personalised text.
Link to this answerWhy do the colours differ from my screen?
A lit screen and printed fabric reproduce colour differently. First check the nozzles, then the artwork input profile and the print profile for your ink, film and RIP mode.
Avoid repeated RGB/CMYK conversions. For a brand colour, approve a sample transferred onto the final fabric.
Link to this answerWhat does the RIP do, and which computer do I need?
The RIP prepares print data, colour management and the white layer. Design software alone does not replace that workflow.
Use the version and driver specified for your INKA configuration. Check operating-system and licensing requirements before changing computers; Mac or Windows compatibility depends on the supplied software.
Link to this answerThe RIP will not open or print: what should I check?
If the software will not open, check its licence and USB dongle if your version uses one. If a job processes but does not print, check machine status, a paused queue and the selected output port.
Record the exact message, RIP version and most recent change before contacting INKA support.
Link to this answerWhite ink
Why does white ink need to stay homogeneous?
White-ink pigments can settle while idle. Poorly mixed ink can produce uneven coverage.
On your INKA, follow the agitation procedure specified for its reservoir or ink supplies. Do not improvise vigorous shaking or work inside the ink circuit: the method depends on the configuration.
Link to this answerDoes white-ink circulation replace maintenance?
No. Where fitted to your INKA model, circulation helps keep ink moving through part of the circuit. It does not by itself clean the nozzles, capping station or wiper.
Keep the pre-production checks and maintenance routine for your machine, even when agitation and circulation are automatic.
Link to this answerMy white layer is too transparent: where do I start?
First print a nozzle check that includes white. If it is incomplete, follow the manual for the ejection fault. If it is correct, check ink level, mixing and the RIP underbase preview.
Then compare a small transfer on the intended fabric. A large increase in white-ink output will not fix an ink-supply fault.
Link to this answerNo white prints: is it a setting or a fault?
If white appears in the nozzle check but not in your design, check that the white channel and underbase are enabled in the selected RIP mode.
If the nozzle check has no white either, check alerts and ink level. Follow the specified cleaning procedure, then send the test to INKA support if the fault persists before dismantling the circuit.
Link to this answerWhy does white show around the coloured edges?
A uniform halo may come from an oversized underbase: its inward offset, called “choke”, is adjusted in the RIP. A shift mainly on one side may instead indicate an alignment problem.
Check the layers, then use a small test chart. Do not copy pixel values from a different resolution or hide major misalignment with excessive choke.
Link to this answerPrint quality
How do I read a nozzle check?
Compare the pattern with the example in your INKA manual: expected lines should be present and correctly positioned, including white. Missing or deflected lines indicate a fault to address before production.
Keep a photo of the test, run the recommended cleaning and compare the new pattern. A printed photograph is not a substitute for this check.
Link to this answerWhy do horizontal bands appear?
Start with a nozzle check. If the nozzles are correct, check film loading and feed: incorrect advance can create bands even without missing nozzles.
Use the feed calibration specified for your INKA and that media. Change one setting at a time and compare a small print before restarting the roll.
Link to this answerWhy is the design blurred or doubled?
First inspect the artwork at print size. If it is sharp, compare a nozzle check and an alignment chart: drop-positioning problems can be distinguished from low-detail artwork.
Check film flatness and use only the alignment adjustments specified in the manual. Do not change head height at random.
Link to this answerWhy does ink bead up or spread on the film?
Check the printable side and film reference: the coating must suit DTF ink. A matte or glossy appearance alone may not identify the correct side.
Try a clean section of compatible film, then check the RIP mode and specified media conditions. Avoid guessing with extra heat or reduced ink.
Link to this answerWhat causes drops or streaks on the print?
Deposits around the carriage can collect ink and release it onto the film. Raised film can also touch the head.
Pause the job, check flatness and follow the accessible maintenance steps specified for your INKA. Do not rub the nozzle face. If marks return, send photos and a nozzle check to support.
Link to this answerThe film wrinkles, skews or touches the head: what should I do?
Stop the job to prevent further contact. Check loading, roll tension, obstructions and film condition according to the manual. Excessive heat exposure can also deform the media.
Reload suitable film without pulling the carriage. If a collision occurred or the issue returns, have your INKA checked before another run.
Link to this answerPowder & curing
When and how should I apply powder?
Apply powder evenly while the ink is still wet. Remove excess before curing to keep consistent coverage over the design.
On an INKA line with a shaker, use a short trial to check that powdering and speed keep up with printing. A missed area will not be fixed simply by pressing longer.
Link to this answerWhy does powder remain outside the design?
Inspect the film before curing: remove excess powder from unprinted areas. Also check the artwork and white underbase, as stray pixels can create nearly invisible printed areas.
Check film cleanliness and storage conditions. Set contaminated samples aside rather than curing unwanted residue onto the fabric.
Link to this answerWhich curing temperature and time should I use?
There is no single setting for every film, powder and oven. Start with the consumable technical sheet and your INKA equipment manual. The displayed temperature may differ from the temperature reached by the transfer.
Validate melting and the durability of a transferred sample. Always distinguish powder curing from heat-press application.
Link to this answerWhat if the powder stays grainy or the transfer looks oily?
If powder has not melted evenly, check the curing recipe, coverage and dwell time. An oily appearance or damp areas after storage can also indicate a moisture problem.
Isolate the batch and repeat a trial with properly stored consumables. Do not judge durability by shine alone: check a transferred sample and its wash performance.
Link to this answerWhat ventilation is needed for powdering and curing?
Provide extraction suited to workstation dust and emissions, following the safety data sheets for your inks, powders and cleaning products. Keep containers closed and avoid making powder airborne.
When preparing your INKA workshop, have ventilation and necessary protection checked for the actual products used; a lack of odour does not validate ventilation.
Link to this answerPressing & garment durability
How should I set the heat press?
Use the temperature, time and pressure combination specified for the transfer and fabric. Check actual platen temperature using a method suitable for the press and ensure even contact, without seams or zips beneath the design.
In your INKA workshop, keep a settings record for each fabric/transfer combination, validated by adhesion and wash testing.
Link to this answerShould I peel the film hot, warm or cold?
The film reference determines how to peel it. A cold-peel film must cool as instructed; a hot-peel film follows a different procedure.
If the design lifts with the film, stop pulling and check the instructions and application. Do not adopt a peeling method from a different consumable.
Link to this answerIs a second press necessary?
Only when the transfer system specifies it. Some require finishing after peeling; others are designed for a single application step.
Also follow the cover-sheet instructions. An improvised second press can change the finish or overexpose heat-sensitive fabric.
Link to this answerWhy do edges lift or the print crack in the wash?
Check the complete application: powder coverage, curing, actual temperature and even pressure. A design that initially looks bonded may still be poorly fixed. Also check seams and fabric compatibility.
Compare a small trial changing one parameter at a time and follow wash instructions. If several batches are affected, keep samples for INKA diagnosis.
Link to this answerWhy does white turn pink or grey on polyester?
Fabric dyes may be migrating into the transfer, sometimes becoming visible after a delay. This differs from a white layer that was already transparent before pressing.
Test the garment batch and a transfer system suitable for migration control. Stay within its validated heat range: adding white or arbitrarily lowering temperature is not a reliable solution.
Link to this answerWhich washing instructions should I give customers?
Follow both transfer and garment care instructions, using the more restrictive requirements, including the wait before the first wash. Where specified for the system, favour cold washing and gentle or air drying.
Validate these instructions on your own samples. Durability depends on the fabric, transfer and application, not just your INKA print setting.
Link to this answerMaintenance & assistance
Which daily checks should I make on my INKA?
Before production, check alerts, ink levels, waste-container capacity and film condition. Run a nozzle check, then the operations specified in the manual.
At the end of the session, follow the routine for accessible areas, including the wiper and capping station where specified for your model. Use prescribed tools and fluid without rubbing the nozzle face.
Link to this answerCan I keep repeating powerful cleaning cycles?
Avoid repeated intensive cycles without a diagnosis. They consume ink and do not solve every cause of poor ejection. Compare nozzle checks and follow the sequence specified for your machine.
If recovery remains inadequate, request an INKA diagnosis. Do not force fluid into a head or damper with a syringe without a validated procedure.
Link to this answerHow should I prepare for a weekend or a longer shutdown?
Plan the shutdown using the procedure for your INKA model and the intended duration. Check consumables and waste collection, then preserve the conditions needed for automatic maintenance where required by the manual.
Do not assume you should unplug everything or flush the circuit. Confirm the procedure for a long absence; on return, inspect the machine and check the nozzles.
Link to this answerHow should I store supplies and control workshop conditions?
Measure temperature and humidity near the printer and follow the ranges specified for the machine and its supplies. Keep inks and powders closed, retaining references, dates and batch numbers.
Protect properly cured transfers from moisture in suitable packaging. Do not mix unknown ink formulations: confirm compatibility before changing ink in your INKA.
Link to this answerWhat should I prepare for INKA support?
Prepare the model and serial number, exact error message, a recent nozzle check and photos of the defect. Add the RIP version, profile, consumable references and workshop conditions.
Explain when the issue started and what you have already tried. For a transfer fault, also include the fabric and curing and press settings.
Link to this answerThis guidance covers textile DTF. For maintenance procedures and production settings, follow your INKA model manual and the specifications for the consumables used.
