Sublimation printing offers a fantastic way to produce vibrant, durable designs on polyester fabrics and polymer-coated items. However, like any printing process, it can present a range of challenges. Below, we explore the most common sublimation issues—and how to solve them—so you can continue creating high-quality products with minimal downtime. For all your sublimation needs, trust West Rand Sublimation Supplies at sublimationsupplies.co.za.
1. Faded or Dull Colours
Are your prints looking washed-out or lacking vibrancy? It’s a common problem with multiple potential causes.
- Incorrect Time or Temperature:
Sublimation requires a specific heat range (usually 190–200°C) for 40–60 seconds. If your time or temperature is too low, the inks won’t fully transfer. - Wrong Substrate:
Sublimation inks only bond with polyester or polymer coatings. Printing on cotton or non-coated surfaces will result in faded designs. - Insufficient Pressure:
Even, consistent pressure is needed for ink to transfer properly. A loose press can cause incomplete sublimation. - Solution:
Double-check your heat press settings, ensure your product is polyester-based or coated, and use the correct pressure. If you’re unsure, consult the product guidelines or reach out to West Rand Sublimation Supplies for advice.
2. Ghosting or Shadow Images
Ghosting occurs when the transfer paper shifts during the pressing process, leading to blurry, overlapping images.
- Paper Shift:
If the transfer paper moves even slightly while hot, the ink can reapply in the wrong place. - Static Electricity:
Static can sometimes lift lightweight paper off the substrate. - Solution:
Secure your transfer paper with high-temperature tape or adhesive spray. Handle the press carefully to avoid jostling. Let your substrate cool slightly before moving it.
3. Uneven or Patchy Transfers
Sometimes certain areas of the print transfer perfectly, while others remain faint or blotchy.
- Inconsistent Pressure:
If your heat press is not distributing pressure uniformly, some regions won’t receive enough contact. - Wrinkles or Moisture:
Wrinkles in the garment or moisture in the substrate can cause patchy printing. - Solution:
Check that your press is level and evenly tightened. Place a towel folded two or three times under your product that is being pressed. Use a lint roller and pre-press garments to remove moisture and wrinkles before sublimating.
4. Banding or Lines in the Print
Notice stripes or missing lines of color in your sublimation prints? This issue
typically indicates a printer-related problem.
- Clogged Printhead Nozzles:
Dried ink or dust can block nozzles, causing lines or gaps in your prints. - Low Ink Levels:
If ink cartridges run low, the printer may struggle to maintain consistent flow. - Solution:
Run a nozzle check and cleaning cycle. If lines persist, consider replacing or refilling cartridges. For best results, use high-quality sublimation inks from a reputable supplier like West Rand Sublimation Supplies.
5. Colors Appear “Off” or Incorrect
Getting a completely different hue than expected? Sublimation printing can be sensitive to color management settings.
- Incorrect ICC Profile:
Sublimation requires an ICC profile specifically calibrated for your printer, inks, and paper. - Double Profiling:
Your design software and printer driver might both be applying color profiles, causing color distortion. - Solution:
Ensure you’re using the correct ICC profile and disable color management in the printer driver if your software is already handling it. Check out our detailed article on color calibration at sublimationsupplies.co.za.
6. Substrate Damage or Melting
Pressing at too high a temperature or for too long can warp or melt certain items.
- Excessive Heat/Time:
Different substrates have varied heat tolerances. Exceeding those limits can cause damage. - Poor Substrate Quality:
Cheaper blanks may have lower-quality polymer coatings prone to damage under high temperatures. - Solution:
Use substrates rated for sublimation, and follow the recommended time and temp guidelines.
If you’re unsure, consult with West Rand Sublimation Supplies for product-specific advice.
Prevention & Best Practices
While troubleshooting skills are crucial, prevention is even better.
Here are some practices to help you avoid common sublimation pitfalls:
- Regular Maintenance:
Keep your printer clean, run nozzle checks, and use fresh ink to minimize printhead blockages. - Calibrate Your Colors:
Color management is essential. Use ICC profiles designed for your printer, ink, and paper combination. - Follow Manufacturer Guidelines:
Each substrate often has a recommended temperature, time, and pressure setting. Adhere to these for consistent results. - Invest in Quality Blanks:
High-quality blanks ensure better ink adhesion and more reliable transfers, saving you time and money.
