Frequently Asked Questions (FAQs) About Heat Transfer Prints

1. How to distinguish between digitally printed and screen-printed heat transfers?

Answer:

• Screen printing requires separate passes for each color (e.g., 4 colors = 4 prints), increasing cost per additional color.

• Digital printing produces multiple colors in a single pass, with no extra charges for added colors.

• 

2. What does "adding a white base" mean, and what is its purpose?

Answer:
A white base enhances the opacity (better coverage) and color adhesion of the transfer by increasing its thickness.

3. Does anti-sublimation treatment completely prevent fabric bleed-through?

Answer:
Anti-sublimation resists dye migration (common in polyester/nylon fabrics) by blocking/absorbing dyes. However, effectiveness varies by fabric type, with a typical reference period of 3–6 months.

4. What factors affect the durability of heat transfers?

Answer:
Key factors include:

• Fabric type (cotton holds better than synthetic blends).

• Washing method (cold water, inside-out recommended).

• Printing technique (screen prints last longer under friction).

5. Can heat transfers be applied to dark-colored fabrics?

Answer:
Yes, but a white underbase is often needed for vibrant colors on dark textiles to prevent fabric show-through.

6. What’s the difference between hot peel and cold peel transfers?

Answer:

• Hot peel: Removed immediately after pressing (suitable for stretchy fabrics).

• Cold peel: Cooled before removal (better for intricate designs).
