Frequently Asked Questions
Sublimation Printing FAQs
Sublimation printing and heat transfer printing are two popular methods for customizing apparel, mugs, and an array of promotional items. Below, you’ll find answers to some of the most common questions people ask when choosing and using these printing techniques.
1. What is Sublimation Printing?
Sublimation printing is a process where special inks turn into gas when heated and bond with polyester fibers or a polymer coating on solid surfaces. This allows designs to become part of the substrate, resulting in vivid, long-lasting images that don’t peel or crack.
2. What Materials Can I Use for Sublimation?
Sublimation works best on items with at least 65% polyester or those that have a polymer coating. Common examples include polyester T-shirts, mugs, metal photo panels, phone cases, and ceramic tiles. Natural fibers like cotton do not hold sublimation inks directly unless they are specially treated.
3. Do I Need a Special Printer or Ink?
Yes. Sublimation printing typically requires a dedicated sublimation printer or a converted inkjet printer that uses sublimation inks. Standard inkjet inks won’t bond to polyester because they’re not formulated for sublimation.
4. Why Are White or Light-Coloured Fabrics Recommended?
Sublimation ink is translucent, meaning it doesn’t include white pigment. When printing on dark backgrounds, your design may not be visible or the colours will appear distorted. White or light colours ensure that the design stays true to the intended color profile.
5. What Temperature and Time Should I Use?
This varies based on the substrate and the brand of ink or transfer paper. Typical settings range from 180°C to 200°C (356°F to 392°F) for 45–60 seconds on fabrics. Hard goods like mugs may require slightly longer heat press times. Always consult your supplier’s guidelines or a time-and-temp chart for best results.
6. How Durable Are Sublimation Prints?
Sublimation prints often last as long as the product itself. The ink bonds with the substrate’s fibers or coating, meaning the design won’t peel or fade easily under normal conditions. Proper washing and care can extend the lifespan even further.
Heat Transfer Printing FAQs
1. What is Heat Transfer Printing?
Heat transfer printing involves using a special transfer paper or vinyl that carries the design. Under heat and pressure from a heat press, the design adheres to the surface of the garment or item. Common methods include heat transfer vinyl (HTV) and heat transfer papers for both cotton and polyester fabrics.
2. What Materials Can I Use for Heat Transfer?
Heat transfer is more versatile regarding materials than sublimation. You can apply certain heat transfer vinyls or papers onto cotton, polyester, or cotton-polyester blends. Just ensure you use the correct type of transfer paper or vinyl for the fabric’s composition.
3. Do I Need a Special Printer or Ink for Heat Transfer?
It depends on the type of heat transfer you’re doing. For heat transfer vinyl (HTV), you’ll need a vinyl cutter (like a Cricut or Silhouette) and a heat press. For heat transfer papers, some can be used with regular inkjet or laser printers, but make sure the paper is compatible with your specific printer and ink type.
4. Can I Layer Colours with Heat Transfer Vinyl?
Yes, you can layer multiple colours of HTV to create detailed designs. However, you should follow the recommended pressing times and instructions from the vinyl manufacturer to ensure proper adhesion between layers.
5. What Are Typical Heat Press Settings for Heat Transfer?
Each material and vinyl brand has slightly different requirements. Generally, most HTV presses at:
150–160°C (302–320°F) for 10–20 seconds. Heat transfer papers might require temperatures up to
180–200°C (356–392°F) for 20–30 seconds. Always check the manufacturer’s guidelines.
6. How Durable is a Heat Transfer Print?
With proper application and care, a heat transfer print can last for dozens of wash cycles. Durability often depends on factors like the quality of the vinyl or paper used, correct temperature and pressure settings, and following recommended washing instructions.
General Tips & Best Practices
- Pre-Press Your Garment: Remove moisture and wrinkles before applying your transfer.
- Use the Right Tools: A reliable heat press, quality transfer materials, and recommended inks can significantly improve outcomes.
- Perform Test Prints: Experiment with settings on a scrap piece of material to fine-tune temperature, time, and pressure.
- Keep It Clean: Regularly wipe down your heat press or cutter to prevent dirt and debris from affecting transfer quality.
- Store Materials Properly: Keep your vinyl and papers in a cool, dry place, away from direct sunlight.
