Sublimation
Sublimation Mug Time and Temperature
Mugs are the blank most makers start with — and the one most likely to come out faded or yellowed when the time and temperature are off. Here are common starting points for 11oz and 15oz mugs in a mug press or a convection oven, plus how to read your results.
Quick answer
A common sublimation mug starting point is 350–400°F (175–205°C) for about 150–210 seconds (roughly 2.5–3.5 minutes) in a mug press. Lower-temperature presses run longer; hotter presses run shorter. 11oz and 15oz mugs are similar — test with your blanks and press, then record what works.
Mug settings at a glance
| Mug | Temp | Time | Method |
|---|---|---|---|
| 11oz mug | 350–400°F (175–205°C) | ~150–180 s | Mug press |
| 15oz mug | 350–400°F (175–205°C) | ~180–210 s | Mug press |
| 11oz / 15oz | ~365–385°F (185–196°C) | ~5–7 min | Convection oven |
Common starting points. Lower temperatures run longer; hotter presses run shorter. Your blanks and equipment fine-tune these.
The time–temperature trade-off
Mug presses don't all agree on a single number, and that's fine — sublimation works across a range. A common starting point is 350–400°F (175–205°C) for about 150–210 seconds (roughly 2.5–3.5 minutes). The key idea is that time and temperature trade against each other: a press running at the lower end of the temperature range needs the longer end of the time range, and a hotter press needs less time. Pick a point in the middle, test, and adjust one variable at a time.
11oz vs 15oz
An 11oz and a 15oz mug press at the same temperature, but the larger 15oz has more ceramic mass and a taller wrap, so it generally wants a little more time to bring the whole coated surface up to heat. Start an 11oz toward the lower end of the time range and give a 15oz the upper end. If the top or bottom band of a tall mug looks lighter than the middle, that's a sign the wrap or element isn't making even contact — reseat the mug and the transfer.
Press vs convection oven
A mug press heats one wrap at a time with direct contact and is the fastest route. A convection oven (with mug wraps/clamps) lets you do several mugs at once but runs longer — a common starting point is around 365–385°F for about 5–7 minutes once the oven is fully preheated. Ovens hold heat more evenly around the whole mug, which many makers like for handles and curved areas, at the cost of speed.
Get a clean wrap
- Use coated, sublimation-ready blanks. A plain ceramic mug has no polymer coating for the ink to bond to and will wash off.
- Tape tightly. Heat-resistant tape on both seams keeps the transfer from shifting — movement is the main cause of ghosting.
- Trim and wrap snug. Air gaps under the paper show up as light or blurry patches.
- Cool down controlled. Drop the mug into room-temperature water or set it on a rack right after pressing; don't let a hot transfer slide.
Reading your result
Two failures point in opposite directions. Faded or dull usually means not enough time or temperature (or a low-quality blank) — the ink never fully gassed into the coating, so add time or heat. Yellow tint or a ghosted double image usually means too much time or temperature, or the transfer moved — pull the numbers back and tape tighter. Change one thing at a time so you know which adjustment did it.
Because every press model and blank brand has its own sweet spot, the fastest way to stop wasting mugs is to write down the exact temp and time that gave you a crisp, full-color wrap — then repeat it instead of re-guessing.
Frequently asked questions
What temperature and time for sublimation mugs? +
A common starting point for sublimation mugs is 350–400°F (175–205°C) for about 150–210 seconds (roughly 2.5–3.5 minutes) in a mug press. Lower-temperature presses run longer, hotter presses run shorter. Always test with your blanks and press, then record what works.
Are 11oz and 15oz mug settings different? +
They are close, but a 15oz mug has more mass and a larger wrap area, so it usually needs a little more time than an 11oz at the same temperature. Start an 11oz near the lower end of the time range and give a 15oz the higher end, then fine-tune.
Why are my sublimation mugs faded or dull? +
Faded, washed-out mugs usually mean not enough time or temperature, or a poor-quality coated blank. The ink never fully gasses into the coating. Increase time or temperature slightly and make sure you are using coated sublimation-ready mugs, then test again.
Why are my sublimation mugs yellow or ghosted? +
A yellow tint or hazy double image usually means too much time or temperature, or the transfer shifted during or after pressing. Lower the time or temperature, tape the transfer tightly, and avoid letting it move when you remove the mug from the press.
