To sublimate a tumbler, print a mirrored design on sublimation paper, wrap it tightly around a sublimation-coated tumbler, tape it, and heat it in a tumbler press or convection oven at the blank or press maker's recommended time and temperature. Then remove the tumbler with gloves and peel the paper. The wrap is where most people go wrong: any gap between paper and tumbler shows up as a blurry or faded patch.
Below is the full process, the starting settings published by press and blank makers, and fixes for the most common problems.
What you need
- A sublimation-coated tumbler. Plain stainless, powder-coated or painted cups won't take the ink. Straight-walled blanks are easiest. See our best sublimation tumblers.
- A sublimation printer and ink, and sublimation paper. Any 8.5-inch printer handles a 20 oz skinny wrap. Paper picks are in our sublimation paper guide.
- A tumbler press (or a convection oven used only for crafts, plus shrink-wrap sleeves).
- Heat-resistant tape, heat-resistant gloves and butcher paper or a Teflon sheet.
- A ruler or flexible tape, scissors or a paper trimmer, and a lint-free cloth.
How to sublimate a tumbler with a press, step by step
- Measure the tumbler. Measure the height of the straight section and the circumference. HTVRONT suggests adding about 2 mm to the circumference for overlap, or cutting to the exact length if you want no overlap at all.
- Size the design. Set your canvas to those dimensions; our sublimation tumbler size guide shows the math. Keep critical text and faces away from the seam.
- Mirror and print. Turn on mirror (or "reverse") in your print settings and print on the coated side of the sublimation paper. Use the paper and ink maker's recommended media setting.
- Let the print dry. HTVRONT says the printed image should be completely dry before transferring. Damp prints blur.
- Clean the tumbler. Wipe it with a lint-free cloth; HTVRONT suggests rubbing alcohol and letting it dry fully. A fingerprint can show in the final print.
- Trim the paper. Don't let paper run past the rim or base. HTVRONT warns that excess paper at the edges folds and causes misprints or faded edges.
- Wrap tightly and tape. Wrap the design ink-side in against the tumbler. Tape the seam first, then the top and bottom edges. Run a flat scraper or squeegee along the seam to push out trapped air. The tighter the wrap, the sharper the result.
- Fit the press mat, if your press uses one. HTVRONT's A200, for example, uses a 4.0 mm mat for 15–20 oz stainless and 16 oz glass, a 2.0 mm mat for 30 oz stainless, and a dedicated mat for 40 oz handled tumblers.
- Preheat and load. Bring the press to temperature, insert the tumbler, and start the cycle right away. HTVRONT recommends pressing Start within 10 seconds of loading to avoid a darker, yellowish image.
- Remove promptly. When the timer ends, take the tumbler out within about 10 seconds (HTVRONT's advice again), using gloves.
- Peel and cool. Let it cool for a few minutes, then peel the tape and paper. Inspect for pale bands or blurry areas before you wash it.
Tumblers with handles
Handled 40 oz tumblers need a little more prep. For its A200H kit, HTVRONT says to remove the handle with a screwdriver first, and to print full-coverage designs in three sections (upper, middle and lower), taping them on in the order lower, middle, upper. If the handle can't come off, HTVRONT's general tumbler guide says to face it away from the heating element and use medium pressure, since high heat can weaken or discolor it.
Step-by-step: sublimating a tumbler in an oven
An oven works well for tapered cups, odd shapes and batches. Still choosing a printer for wraps? See our best sublimation printer for tumblers.
- Wrap and tape exactly as above.
- Add a shrink-wrap sleeve over stainless tumblers, and shrink it snug with a heat gun. This replaces the press's pressure. Don't let shrink wrap touch glass blanks.
- Preheat a convection oven used only for crafts. HTVRONT suggests 375°F (190°C) as a starting point and an oven thermometer, because ovens drift.
- Bake on a foil-lined rack for about 6–10 minutes depending on size, per HTVRONT. Rotate the tumbler 180 degrees halfway through.
- Check and extend. If the design hasn't fully transferred, HTVRONT suggests about 2 more minutes.
- Remove with gloves, cool for a few minutes and peel.
Ventilate the room. HTVRONT notes that slight smoke during pressing is normal because the ink turns to gas.
Starting settings from the makers
These are published starting points, not guarantees. Presses, ovens and blank coatings differ, and the makers themselves give different numbers for different equipment. Always start with your own press and blank instructions and adjust after a test piece.
| Blank and method | Starting point | Source |
|---|---|---|
| Stainless tumbler, tumbler press | 375–400°F (190–204°C), 50–60 sec, medium pressure | HTVRONT tumbler guide |
| Stainless tumbler, tumbler press (alternative) | 300°F (150°C), 4–6 min, medium to firm pressure | HTVRONT sublimation tumbler guide |
| Stainless tumbler, convection oven | 375°F (190°C), 6–10 min, rotate halfway | HTVRONT tumbler guide |
| 16 oz glass can, heat press | 400°F (200°C), 90 sec | HTVRONT glass blank listing |
| 16 oz glass can, oven | 400°F (200°C), 8 min | HTVRONT glass blank listing |
| Ceramic mug, Geo Knight DK3 mug press | 400°F, 5 min to begin; try 30 sec less once results are good | Geo Knight DK3 manual |
Why the spread? HTVRONT doesn't explain the difference between its two guides, but the pattern is familiar: heater design, wall thickness and coating all change how fast heat reaches the ink, so one press's 60 seconds is another's 4 minutes. If your press came with a quick reference chart, use it. HTVRONT, for example, points A200 owners to the chart in its manual. For a full table by blank, see our sublimation temperature chart.
Sublimation time & temperature chart
Geo Knight notes that your transfer supplier's instructions are more accurate than generic figures.
Dial it in: run one test piece first. HTVRONT's rule of thumb: if a transfer looks faded, add about 10 seconds; if colors bleed or scorch, lower the temperature by 5–10°F. Change one setting at a time.

Common mistakes (and fixes)
A blurry band or ghost image
Paper moved or lifted. Tape more tightly at the seam and both edges, and squeegee the seam. Remove the tumbler and peel without letting the paper slide. More on this in our sublimation ghosting guide.
A dark line at the seam
That's a double layer of ink where the paper overlaps. HTVRONT's fix: cut the paper to the exact circumference, or stick a strip of heat-resistant tape on the back of the paper's edge to block the extra ink.
Faded areas near the top or bottom
Usually paper that isn't flat against the tumbler, or paper overhanging the edges. Trim right to the straight section and keep the wrap snug. For mugs, Geo Knight's DK3 manual makes the same point: cover sheets that overlap the edges cause wrinkles and white lines.
Pale, washed-out colors overall
Too little heat or time, or the wrong side of the paper. Confirm you printed on the coated side with sublimation ink, check press temperature with a thermometer, and add time in small steps. HTVRONT suggests 30–60 seconds more when a press cycle under-transfers.
Yellowed or brownish design
Too much heat time. Remove the tumbler promptly and shorten the cycle slightly.
Uneven results in an oven
Ovens have hot spots. Rotate halfway, use an oven thermometer, and press one test cup per batch. HTVRONT also advises against pointing fans or air conditioning at a tumbler press during pressing.
Quick checklist before every tumbler
- Design mirrored and sized to the straight section
- Print fully dry
- Tumbler wiped clean
- Paper trimmed, no overhang at rim or base
- Seam and edges taped, seam squeegeed
- Correct mat or shrink wrap fitted
- Press or oven preheated, settings from your maker's chart
- Gloves on
FAQ
How long do you press a sublimation tumbler?
It depends on the press. HTVRONT gives 375–400°F for 50–60 seconds at medium pressure in one tumbler guide and 300°F for 4–6 minutes in another. Use your press maker's chart as the starting point and adjust after a test tumbler.
Can I sublimate a tumbler in a regular oven?
A convection oven that never cooks food works; HTVRONT suggests 375°F for 6–10 minutes, rotating the tumbler halfway and checking the oven with a thermometer. A conventional oven can work but heats less evenly, so rotate more carefully.
Why is there a line where my sublimation paper overlaps?
The overlapping paper transfers a double layer of ink. HTVRONT recommends cutting the paper to the exact circumference, or putting a strip of heat-resistant tape on the back edge of the paper to block extra ink at the overlap.
Do I need shrink wrap to sublimate a tumbler?
Not with a tumbler press, which supplies the pressure. In an oven, a shrink-wrap sleeve tightened with a heat gun holds the paper against the tumbler. Keep shrink wrap off glass, as HTVRONT warns.
Why did my tumbler come out yellow or dark?
Usually from extra heat time. HTVRONT advises starting the press within 10 seconds of loading and removing the tumbler within 10 seconds after the countdown ends, so it doesn't keep baking.
