Frequently Asked Questions

Q

What temperature should I set my heat press to for HTV on cotton?

Set your heat press to 305°F (152°C) for HTV on 100% cotton. Press for 15 seconds at medium pressure, then hot peel the carrier sheet. Always pre-press the garment for 3 seconds to remove moisture and wrinkles.

  • Pre-press garment for 3–5 seconds to remove moisture – trapped steam causes HTV to lift
  • Use a Teflon sheet or parchment paper between the press and carrier to prevent scorching
  • Mirror (reverse) your design before cutting – HTV is always applied face-down
  • Wait 24 hours before first wash; wash inside-out on cold to extend vinyl life by 50+ washes
  • If edges lift after peeling, re-press for 5 seconds with the Teflon sheet over the vinyl
Q

What is the difference between HTV and sublimation?

HTV (heat transfer vinyl) is a cut material that sits on top of the fabric and works on cotton, polyester, and blends. Sublimation uses special ink that converts from solid to gas and bonds with polyester fibers, producing vibrant, permanent prints that never crack or peel. Sublimation does not work on cotton.

  • HTV works on cotton, polyester, and blends; sublimation requires 65%+ polyester content
  • HTV cost: $0.50–$2.00 per sq ft; sublimation ink: $0.02–$0.10 per print on transfer paper
  • HTV lasts 50–75 washes before cracking; sublimation is permanent and never peels
  • Sublimation is best for all-over prints and photos; HTV is better for single-color text and logos
  • DTF transfers bridge the gap – work on all fabric colors and cost $0.30–$0.80 per transfer

Q

What do light, medium, and heavy pressure mean on a heat press?

Light pressure means a gentle push, around 2–3 on a pressure dial, used for delicate fabrics like nylon. Medium pressure is a firm press at 4–6 on the dial, suitable for most HTV and DTF applications. Heavy pressure is a strong clamp at 7–8+, required for sublimation and infusible ink to fully transfer the design.

  • Light (2–3): nylon, silk, and thin performance fabrics that scorch or melt easily
  • Medium (4–6): cotton T-shirts, hoodies, and poly-blend garments with HTV or DTF
  • Heavy (7–8+): sublimation and infusible ink need maximum contact for full ink transfer
  • Test with a sheet of paper – at correct pressure it should slide out with firm, even resistance
  • Uneven pressure causes partial transfers – check that the platen is level with a heat gun thermometer
Q

Can I sublimate on dark-colored garments?

Sublimation ink is transparent, so it only works well on white or very light-colored polyester garments. On dark fabrics the design will be invisible or severely washed out. For dark garments, use HTV or DTF transfers instead, which apply an opaque layer on top of the fabric.

  • Sublimation only works on white or pastel substrates – ink has no white pigment layer
  • For dark cotton: use white HTV as a base layer, then layer printed HTV on top
  • DTF transfers print a white ink under-layer, making them ideal for dark fabrics at $0.30–$0.80 each
  • Infusible Ink by Cricut works on dark blanks with a poly-coated white surface
  • Always test a 2×2" swatch before committing to a full design on any new substrate

HTV on cotton is the most common heat press application. Press at 305°F for 15 seconds with medium pressure. The carrier sheet is peeled while still hot. Always mirror your design before cutting.

Sublimation requires high heat (400°F) and heavy pressure for a full 60 seconds. The ink turns to gas and permanently bonds with the polyester fibers. Pre-press for 5 seconds to remove moisture.

Formulas Used

Celsius to Fahrenheit

°F = (°C × 9/5) + 32

Convert heat press temperature between Celsius and Fahrenheit scales.

Where:

°F= Temperature in Fahrenheit
°C= Temperature in Celsius

Settings Lookup

Settings = Lookup(Transfer Method, Substrate)

Heat press settings are determined by the combination of transfer method and substrate material. Each combination has a specific temperature, time, and pressure recommendation from manufacturer testing.

Where:

Transfer Method= HTV, sublimation, DTF, or infusible ink
Substrate= Material being pressed: cotton, polyester, blend, nylon, ceramic, or metal
