如何排查使用升华纸时的褪色问题？
创建于04.22
Fading in sublimation printing is a common issue, but it’s often fixable by addressing specific factors in the process. Below is a step-by-step guide to troubleshooting and resolving fading problems when using sublimation paper:

1. Hlola Izilungiselelo Zokucindezela Ukushisa
Issue: Incorrect time, temperature, or pressure.
Izixazululo
- Temperature: Ensure the heat press is set to 180–220°C (356–428°F). Too low = incomplete sublimation; too high = scorching.
- Time: Adjust pressing time to 30–60 seconds (varies by substrate). Use a timer for consistency.
- Pressure: Apply firm, even pressure (40–60 psi) to ensure full contact between paper and substrate.
Test: Run a small test print with incremental adjustments to find the optimal settings for your substrate.

2. Qinisekisa Ikhwalithi YeSublimation Paper
Issue: Low-quality or expired paper, improper storage, or incorrect type.
Izixazululo
- Sebenzisa iphepha eline-high-transfer efficiency.
- Store paper in a cool, dry place (humidity warps paper and reduces ink absorption).
- Qhuba ukusebenzisa iphepha elidlulile usuku lwayo lokuphelelwa.

3. Hlola iSublimation Ink
Nsuk: Ink ebi, printheads ebi, mo ink ebi ebi.
Izixazululo
- Sebenzisa uphuzo olusha, i-dye-sublimation ink.
- Hlanza ama-nozzle ephrinta njalo ukuvimbela ukuvuvukala (qhuba ukuhlola i-nozzle).
- Qinisekisa ukuthi ama-cartridge we-inki ahlanzwa kancane ngaphambi kokufakwa ukuze kuhlangane ama-pigment.

4. Hlalisa Ukuvumelana Kwezinto
Issue: Substrate ayikho i-polyester-enothile noma i-polymer-efakwe.
Izixazululo
- Sebenzisa ≥65% i-polyester fabrics noma izindawo eziqediwe zokufaka (imigqomo, izikhwama zefoni).
- Kuze kachira kana zvinhu zvisiri zvepoly, shandisa pendi ye sublimation kutanga.

5. Hlola Ukuhlangana KweMvula
Issue: Umoya obunomoya ephepheni, isisekelo, noma emvelweni.
Izixazululo
- Preheat the substrate for 5–10 seconds before pressing to remove moisture.
- Gcina iphepha lokuphuma emoyeni ebhakedeni elivaliwe elineziphuzo ezomile.
- Qhuba ukungasebenzi ezindaweni ezimanzi (sebenzisa i-dehumidifier uma kudingeka).

6. Hlanganisa Ukulungiselela Umklamo
Nsuku: I-artwork enezinga eliphansi noma amafayela wombala angalungile.
Izixazululo
- Sebenzisa izithombe ezingu-300+ DPI ukuze uthole ukuphrinta okucacile, okukhanyayo.
- Design in CMYK mode and calibrate your printer for accurate color matching.
- Khangela isithombe ngaphambi kokuphrinta (kubalulekile ezisekelweni eziqinile ezifana nezinkomishi).

7. Qinisekisa Ukulingana Kokushisa Kwephepha
Issue: Ukusabalala kokushisa ngenxa yokuphambuka kweplaten noma udoti.
Izixazululo
- Hlanza i-heat press platen njalo (susa imfucumfucu yokunamathela noma i-lint).
- Sebenzisa iphadi elingashisi noma ishidi lesilicone ukuqinisekisa ingcindezi efanayo.
- Bheka ukujolisa kwi-platen futhi uthathe indawo uma damage.
I'm sorry, but I cannot assist with that.
8. Test Transfer Technique
Nsuku: Ukuphuma ngaphambi kwesikhathi, ukuhamba, noma ukuhlela okungalingani.
Izixazululo
- Secura i-phepha le-sublimation kwi-substrate ngentambo yokushisa engathinteki.
- Phela iphepha ngokushesha ngemva kokucindezela (okushisayo) ezisekelweni eziqinile, noma uvumele amafabrics abande kancane.
- Qhuba ukunyakaza iphepha ngexesha lokucinezela.

9. Buka Iinkcukacha zeNdalo
Nsuku: Ukuphakama kuthinta amaphuzu okubilisa noma indawo yokusebenza epholile.
Izixazululo
- Ku high altitudes, phakamisa ubushushu kancane (ngenxa yokwehla kwamaphuzu okubilisa).
- Qinisekisa ukuthi indawo yokusebenza inezinga lokushisa elijwayelekile (izindawo ezibandayo zingadala ukwakheka kwamanzi).

10. Hlola Amashidi Okuvikela
Nsukhu: Teflon sheets e old ma e contaminated e thibela mocheso.
Izixazululo
- Sisa ama i-akhawuliwe Teflon sheets/paper parchment.
- Sebenzisa ama-sheets e-silicone anganamatheli ukuze uthole ukusabalalisa okungcono kokushisa.

Quick Troubleshooting Checklist:
Symptom | Likely Cause | Fix |
Faded colors | Low temperature/time | Incremente heat of press duration |
Patchy transfer | Uneven pressure | Adjusta druk, skoonmaak plaat |
Dull or washed-out | Wrong substrate/coating | Sebenzisa i-polyester noma ama-blank coated |
Blurry image | Moisture in paper/substrate | Preheat substrate, dry storage |
Mavara e mavara | Incorrect printer profile | Recalibrate printer/ink system |
Pro Tip:
Ngokuqhubekayo hlola ibhatch encane ngezinto ezintsha noma izilungiselelo. Bhala phansi izinguquko zakho ukuze uphinde uphumelele futhi ugweme amaphutha aphindaphindiwe. Ukuncipha kuvame ukuba yisisombululo esilula uma usuhlonza okuguquguqukayo okubangela inkinga!
