How to Troubleshoot Fading When Using Sublimation Paper？
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. Check Heat Press Settings
Issue: Incorrect time, temperature, or pressure.
Solutions
- 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. Verify Sublimation Paper Quality
Issue: Low-quality or expired paper, improper storage, or incorrect type.
Solutions
- Use high-transfer efficiency paper.
- Store paper in a cool, dry place (humidity warps paper and reduces ink absorption).
- Avoid using paper past its expiration date.
---
3. Inspect Sublimation Ink
Issue: Expired ink, clogged printheads, or incorrect ink type.
Solutions
- Use fresh, dye-sublimation ink.
- Clean printer nozzles regularly to prevent clogs (run a nozzle check).
- Ensure ink cartridges are shaken gently before installation to mix pigments.
---
4. Evaluate Substrate Compatibility
Issue: Substrate isn’t polyester-rich or polymer-coated.
Solutions
- Use ≥65% polyester fabrics or sublimation-coated hard surfaces (mugs, phone cases).
- For cotton or non-poly materials, apply a sublimation spray coating first.
---
5. Check for Moisture Contamination
Issue: Humidity in the paper, substrate, or environment.
Solutions
- Preheat the substrate for 5–10 seconds before pressing to remove moisture.
- Store sublimation paper in a sealed bag with desiccant packs.
- Avoid working in humid environments (use a dehumidifier if necessary).
---
6. Adjust Design Preparation
Issue: Low-resolution artwork or incorrect color profiles.
Solutions
- Use 300+ DPI images for sharp, vibrant prints.
- Design in CMYK mode and calibrate your printer for accurate color matching.
- Mirror the image before printing (critical for hard substrates like mugs).
---
7. Confirm Heat Press Evenness
Issue: Uneven heat distribution due to a warped platen or debris.
Solutions
- Clean the heat press platen regularly (remove adhesive residue or lint).
- Use a heat-resistant pad or silicone sheet to ensure even pressure.
- Check for warping in the platen and replace if damaged.
---
8. Test Transfer Technique
Issue: Premature peeling, shifting, or uneven alignment.
Solutions
- Secure the sublimation paper to the substrate with heat-resistant tape.
- Peel the paper immediately after pressing (hot) for hard substrates, or let fabrics cool slightly.
- Avoid moving the paper during pressing.
---
9. Review Environmental Factors
Issue: Altitude affecting boiling points or cold workspace.
Solutions
- At high altitudes, increase temperature slightly (due to lower boiling points).
- Ensure the workspace is room temperature (cold surfaces can cause condensation).
---
10. Check Protective Sheets
Issue: Old or contaminated Teflon sheets blocking heat.
Solutions
- Replace scratched or stained Teflon sheets/parchment paper.
- Use non-stick silicone sheets for better heat distribution.

Quick Troubleshooting Checklist:
Symptom | Likely Cause | Fix |
Faded colors | Low temperature/time | Increase heat or press duration |
Patchy transfer | Uneven pressure | Adjust pressure, clean platen |
Dull or washed-out | Wrong substrate/coating | Use polyester or coated blanks |
Blurry image | Moisture in paper/substrate | Preheat substrate, dry storage |
Color shifts | Incorrect printer profile | Recalibrate printer/ink system |
Pro Tip:
Always test a small batch with new materials or settings. Document your adjustments to replicate success and avoid repeat errors. Fading is often a simple fix once you isolate the variable causing the problem!
