Definition
Sublimation printing converts solid dye to gas under heat (~400°F) and pressure, bonding the dye into polyester fibers or polymer-coated substrates. The dye becomes part of the material. Result: vibrant, durable, full-color prints with no perceptible ink layer or hand-feel. Standard for POD mugs, polyester sportswear, photo phone cases, polymer-coated metal items. Won't work on 100% cotton, leather, untreated natural materials.
How sublimation works
- Design print: The design is printed (in mirror-image) onto special sublimation transfer paper using sublimation inks. Inks dry on the paper as solid dye.
- Substrate prep: The polyester garment, ceramic mug, polymer-coated item, etc. is positioned for heat-press application.
- Heat press: Transfer paper is placed face-down against the substrate. Heat press applies ~400°F for 45-90 seconds at moderate pressure.
- Dye sublimation: The solid dye converts directly to gas under heat (the chemistry of "sublimation"). The polyester fibers or polymer coating open up under heat, the gaseous dye penetrates, and as the substrate cools the dye solidifies back inside the material.
- Cool and peel: The transfer paper is peeled off, leaving the design now part of the substrate, not on top of it.
Result: zero hand-feel. Run your hand over a sublimation-printed mug or polyester shirt and you can't feel the print at all, because it's dyed into the material.
Substrates that work with sublimation
| Substrate | Works? | Notes |
|---|---|---|
| 100% polyester apparel | ✓ Excellent | Best results, sportswear, jerseys, athletic wear |
| Polyester-blend apparel (50/50, 65/35) | Partial | Colors look slightly washed; vibrancy proportional to polyester % |
| 100% cotton apparel | ✗ No | Won't bond; use DTG or DTF instead |
| Polymer-coated ceramic mugs | ✓ Excellent | Standard for photo mugs |
| Natural ceramic without coating | ✗ No | Won't bond |
| Polymer-coated metal (tumblers, water bottles) | ✓ Excellent | Standard for branded drinkware |
| Polymer-coated wood (plaques, signs) | ✓ Good | Works on polymer-coated wood blanks |
| Phone cases (polymer) | ✓ Excellent | Standard for custom phone cases |
| Polyester throw pillows, blankets | ✓ Excellent | Standard for photo home decor |
| Glass (without coating) | ✗ No | Use laser engraving or UV printing |
| Leather | ✗ No | Use laser engraving |
| Dark substrates | ✗ Avoid | Sublimation dye is transparent, needs white/light base |
The polymer rule: if it doesn't have polyester fibers or a polymer coating, sublimation won't work. Most natural materials (cotton, leather, untreated wood, natural ceramic, glass) require alternative printing methods.
Sublimation file specs
- Format: PNG with transparent background
- Resolution: 300 DPI at actual print dimensions
- Color profile: sRGB always (sublimation uses RGB workflow, NEVER CMYK)
- No white ink: sublimation has no white ink, so any "white" in your design shows the substrate color underneath
- Substrate-aware design: dark designs on white substrates work best; avoid pure-white designs (the design disappears into the substrate)
- Bleed: 0.125 inches (3mm) for full-wrap mug designs or edge-bleeding apparel prints
- Resolution per product:
- 11oz mug full-wrap: 9×4 inches = 2,700×1,200 pixels
- 15oz mug full-wrap: 9.6×4.1 inches = 2,880×1,230 pixels
- Polyester t-shirt front print: 12×16 inches = 3,600×4,800 pixels
- Standard phone case: 6×3.25 inches = 1,800×975 pixels
Print It My Way generates sublimation-ready PNGs automatically at the correct DPI and color profile.
Sublimation cost per product
| Product | Sublimation cost | Blank cost | Total POD cost | Typical retail |
|---|---|---|---|---|
| 11oz ceramic mug | $2-4 | $4-8 | $6-12 | $20-30 |
| 15oz mug | $2.50-4.50 | $5-9 | $7-14 | $24-35 |
| Polyester t-shirt | $3-5 | $5-10 | $8-15 | $25-35 |
| Polyester sportswear jersey | $5-8 | $12-25 | $17-33 | $45-75 |
| Insulated tumbler 20oz | $4-6 | $8-15 | $12-21 | $25-40 |
| Phone case | $3-5 | $6-12 | $9-17 | $22-35 |
| Throw pillow 18×18 | $5-8 | $10-18 | $15-26 | $30-50 |
| Polyester photo blanket | $8-15 | $15-30 | $23-45 | $50-80 |
Sublimation tends to be cost-competitive with DTG on apparel (no white-underbase complexity on light polyester) and cheaper than DTG on dark polyester products (sublimation dye bonds without needing pretreatment).
Sublimation vs DTG vs DTF
- Sublimation: polyester / polymer-coated substrates only. Zero hand-feel. Lifetime durability. Best for mugs, sportswear, phone cases, photo products.
- DTG: cotton best. Soft hand-feel. 30-40 wash durability. Best for cotton apparel.
- DTF: any fabric. Slight hand-feel. 50+ wash durability. Best for mixed-fabric or performance-fabric apparel.
Most POD stores use 2-3 of these depending on product category. Sublimation for the polyester catalog (mugs, sports apparel, photo products), DTG for cotton apparel, DTF for premium/performance/dark-fabric products.

What is sublimation printing?
Sublimation printing is a process where solid dye is converted directly to gas under heat (~400°F) and pressure, bonding the dye into polyester fibers or polymer-coated substrates. The dye becomes part of the material rather than sitting on top. Result: vibrant, durable, full-color prints with no perceptible ink layer or hand-feel, the design looks and feels like it's been dyed into the product. The catch: sublimation requires polyester or a polymer coating. It won't work on 100% cotton, leather, untreated wood, or natural ceramic. Standard for photo mugs, polyester apparel (jerseys, sportswear), polymer-coated metal items, and many phone case manufacturers.
What products can be sublimation-printed?
Sublimation works on any substrate containing polyester or having a polymer coating that accepts dye. Standard sublimation POD products: (1) Ceramic mugs (with sublimation-ready polymer coating). (2) Polyester apparel, sportswear, jerseys, athletic wear, all-over-print t-shirts. (3) Polymer-coated metal items, water bottles, tumblers, jewelry blanks. (4) Phone cases (sublimation-coated polymer). (5) Polyester throw pillows, blankets, photo prints on fabric. (6) Wood with polymer coating (for plaques). (7) Mouse pads, mouse mats. Sublimation does NOT work on: 100% cotton, leather, untreated natural materials, dark-colored substrates, glass without coating.
How much does sublimation printing cost?
Sublimation cost varies by substrate. Typical 2026 POD sublimation costs: 11oz ceramic mug $2-4 sublimation cost + $4-8 mug blank = $6-12 total POD cost. Polyester t-shirt: $3-5 sublimation cost + $5-10 polyester shirt = $8-15. Polymer-coated tumbler: $4-6 sublimation cost + $8-15 tumbler blank = $12-21. Phone case: $3-5 sublimation cost + $6-12 case blank = $9-17. At typical retail prices ($20-30 mugs, $25-35 polyester apparel), margins are 50-60% after POD costs.
What file specs does sublimation need?
Standard sublimation print file specs: (1) Format: PNG with transparent background. (2) Resolution: 300 DPI at actual print dimensions, e.g., 9×4 inches for 11oz mug full-wrap = 2,700×1,200 pixels. (3) Color profile: sRGB (sublimation uses RGB workflow, NEVER CMYK). (4) No white ink: sublimation has no white ink, anywhere your design is 'white' will show the substrate underneath. (5) Bleed: 0.125 inches for full-wrap or edge-bleeding designs. (6) Substrate-aware design: dark designs work best on white/light substrates.
Sublimation vs DTG vs DTF, when to use sublimation?
Use sublimation when: (1) Substrate is polyester or polymer-coated. (2) You need vibrant, photo-quality, all-over-print designs. (3) You want zero hand-feel (the design is dyed into the material). (4) Durability is critical, sublimation lasts the lifetime of the substrate. Use DTG when: apparel is 100% cotton and you need photo-quality on cotton. Use DTF when: mixed fabric content, performance fabrics, or durability beyond DTG without sublimation's polyester-only constraint. Most POD stores use 2-3 of these methods across different product categories.
Which POD vendors offer sublimation?
Sublimation is standard at all major POD vendors for mugs and polyester products: Printful offers sublimation on mugs, polyester apparel, phone cases, tumblers, mouse pads, throw pillows. Printify offers sublimation through most print providers in their marketplace. Gelato offers sublimation on mugs, photo products, polyester apparel in 30+ countries. Gooten, Apliiq, T-Pop all support sublimation. Photo product specialists like PhotoJaanic (India), Zoomin (India), CustomCanvas (US) use sublimation for canvas, framed prints, mugs, photo blankets. India POD: Printrove, Qikink, Vendor all offer sublimation. For a side-by-side of mug suppliers, see our guide to the best print on demand for mugs.
