Understanding Sublimation Printing
Sublimation printing is a modern method of applying dye to fabrics, primarily polyester-based, through a heat transfer process. The term "sublimation" refers to the phase change where the ink turns from solid directly into gas without becoming liquid.
During sublimation printing, the ink is printed onto a special transfer paper first. When heated, the ink becomes gas and permeates the fibers of the fabric, becoming a permanent part of the material. This process allows for vibrant, full-color prints that don't crack, peel, or fade easily because the dye actually becomes part of the fabric.
Key Benefits of Sublimation Printing
- Vivid, full-color, and photo-quality prints without limits on the number of colors.
- Soft feel since the dye touches the fibers directly without adding a layer on top.
- Durability with no risk of cracking or peeling over time.
- Ideal for all-over prints or designs covering large areas.
What Is Screen Printing?
Screen printing is a traditional printing method where ink is pushed through a mesh screen onto fabric. Each color in the design requires a separate screen and ink application.
Screen printing uses plastisol or water-based inks and creates a layer of ink on top of the fabric, resulting in a vibrant and durable print.
Advantages of Screen Printing
- Cost-effective for large quantity bulk orders because screens can be reused.
- Outstanding color opacity, even on dark fabrics.
- Flexible ink types can produce special effects like puff or metallic finishes.
- Works well on a wide range of materials, including cotton and blends.
When to Choose Sublimation Over Screen Printing
Sublimation printing excels in certain situations where it truly makes sense to choose it over screen printing:
Fabric Choice: Polyester or Polyester Blends
Sublimation works best on polyester or high polyester-content fabrics. This is because the dye bonds with polyester fibers during the heating process. While screen printing can work on cotton, blends, or other materials, sublimation's quality and durability will only be optimal on polyester.
Full-Color, Complex Designs
If your design includes gradients, photographs, detailed illustrations, or many colors, sublimation is a strong option since it allows unlimited colors in one pass without extra cost. Screen printing becomes expensive and intricate with many colors and requires more setup time and cost.
All-Over Printing
Sublimation printing can produce seamless, edge-to-edge prints on shirts and apparel. This is difficult or impossible to achieve cleanly with screen printing, which is generally limited to set areas like chest or back.
Soft Fabric Feel
For apparel where the printed design should feel as natural as the fabric, sublimation is preferred since the dye penetrates the fibers, resulting in no added thickness or texture on top of the garment.
Durability Requirements
The permanent nature of sublimated ink means it won't fade, crack, or peel, making it ideal for items expected to endure heavy use and washing.
When Screen Printing Is Usually a Better Fit
There are times when screen printing still outperforms sublimation:
- Natural fabrics: For cotton or cotton-heavy blends, screen printing delivers better adhesion and vibrant ink colors.
- Small and large runs: Screen printing is cost-effective in large quantities and often works well for smaller runs depending on design complexity.
- Special inks and effects: Screen printing can use specialty inks with various textures, metallic finishes, or puff effects.
- Dark color base fabrics: Screen printing offers more opacity and color vibrancy on dark cotton fabrics compared to sublimation.

Frequently Asked Questions
Can sublimation printing be done on cotton shirts?
No, sublimation printing requires polyester or polyester-blend fabrics because the dye bonds with synthetic fibers. For cotton, screen printing or DTG are better choices.
Is sublimation printing more expensive than screen printing?
Costs vary based on quantity and design complexity. Sublimation can be more affordable for full-color designs or small batches on polyester items, while screen printing often becomes more cost-effective in large bulk orders. Learn more about our bulk pricing options.
Does sublimation printing fade over time?
Sublimation prints are highly durable and resistant to fading, cracking or peeling because the dye becomes part of the fabric itself.
Can sublimation print cover the entire shirt?
Yes, sublimation allows for all-over prints, which is a major advantage over screen printing.
