Sublimation

Sublimation is a digital printing process based on the physical-chemical phenomenon of the same name whereby the ink passes directly from the solid to the gaseous state without passing through the liquid state.

How does it work

The logo is digitally printed on a special sublimation paper with sublimation inks. The paper is applied to the product to be printed, which is then placed in a heat press at a temperature of approximately 180-210°. The pressure and heat sublimate the ink, which is then transferred to the surface of the product. Due to the high temperature, the polyester loosens its molecular structure, allowing the ink in the gaseous state to penetrate directly into the fibres of the material permanently. The result? A print that is resistant to scratches, frequent washing, stress or colour decay.

Some examples of application on promotional items

Sublimation can be used on many types of products, as long as they are white and made of polyester or properly treated with polyester on the surface. Textile products such as clothing, backpacks or fabric bags, ceramic and glass items such as mugs and water bottles, aluminum products, plastic items such as lanyards, mouse pads, luggage belts and many more are just the most popular examples.

Pros and Cons of Sublimation

Pros

Photographic print quality, sharp and bright colour rendering;
It is versatile, it easily adapts to products with flat and circular surfaces;
Large printing area, across the entire surface of the product;
You can print images and photos in full color, including shades;
High coverage;
The print is very resistant to washing and scratches.

Cons

In order for the final result to be identical to the original design, the background of the object to be customized must be white, otherwise the sublimation inks will combine with the color of the product altering the final colors of the design;
It is not suitable for natural fabrics such as cotton or materials such as untreated wood;
It works mainly on synthetic materials, such as polyester, or on objects specially treated with polyester to accommodate color transfer (such as coated ceramic mugs or metal objects treated with polyester);
If the print is permanently exposed to sunlight, the colors may fade over time.
