Sublimation: Correct Time, Temp, and Pressure by Blank Type
Direct Answer:
Sublimation blanks run at 375–400°F (190–204°C). Time depends on the blank — 45–60s for shirts, 4–6min for tumblers. Light-to-medium pressure prevents ghosting and preserves coatings.
Steps
- Print mirrored at 300 DPI and dry ink for 5–10 minutes.
- Lint-roll fabric or wipe hard blanks with alcohol.
- Tape edges tightly - no slack allowed.
- Press or bake according to table below.
- Cool on clean rack to stop dye migration.
- If you see gas marks, reduce time or pressure.
Baseline Specs
| Blank | Temp | Time | Pressure | Notes |
|---|---|---|---|---|
| Poly Tee | 385–400°F | 45–60 s | Light–Med | Pre-press 5–10 s |
| 20oz Tumbler (Oven) | 375–400°F | 4–6 min | — | Shrink sleeve, rotate mid-cycle |
| Ceramic Mug | 385–400°F | 180–240 s | Firm | Pre-heat mug if banding |
| MDF | 385–400°F | 45–70 s | Medium | Mask edges if scorching |
| Aluminum | 385–400°F | 60–90 s | Light | Cool fast for best color |
Risks
- Ghosting = movement → tape or sleeve tighter.
- Dull colors = wrong ICC or too low time/temp.
- Orange peel = too much pressure on metals.
- Yellowing/Brown = overcooked - reduce time.
- Blacks Looking Green= undercooked - increase time/heat.
FAQs
Why are colors dull? Wrong profile or too low time/temp.
Paper lines? Trim edges or use blowout paper.
Do I mirror mugs? Yes, unless design doesn’t need mirroring.
