Which products can be personalised with sublimation (and which cannot)

Introduction

Sublimation is one of the most effective techniques for full-colour personalisation, but it has one very clear condition: the product must be compatible. If it is not, it is not simply a matter of the result “looking worse”; the print may not bond at all, may look dull or may deteriorate quickly. That is why, before buying a garment or ordering a batch of products, it is worth validating the material.

At Vanco Studio we provide custom sublimation on mugs, textiles and gifts from Girona (L’Estartit), with shipping and remote project options. This guide helps you identify what works well, what does not and which details affect durability.

Ideal products for sublimation

The products that work best with sublimation are usually those specifically manufactured for this technique. In day-to-day work, the most common are sublimation-ready ceramic mugs, compatible thermal bottles, textiles prepared for sublimation (especially garments and accessories with a high polyester content), and promotional items designed for colour printing.

Rigid-surface products with the appropriate coating also work very well, such as plaques, puzzles or keyrings designed for sublimation. In these cases the result is usually sharp, with vivid colours and no raised surface (it does not “peel off” like a sticker), provided the substrate is the correct one.

Materials compatible with sublimation

The technical rule is simple: sublimation needs polymer. In textiles, that usually means polyester (or blends in which polyester is predominant). On rigid items, it means a surface with a special sublimation coating (for example, certain finishes on ceramic or prepared metal plaques).

This also explains why the base colour matters. Sublimation does not add “white”: the final colour depends on the design and the product background. If you need faithful colours, a light background is usually the most predictable.

What does not work with sublimation (or is not recommended)

There are two groups: materials that do not accept sublimation and products that “look” suitable but are not because they lack the necessary coating.

In textiles, a 100% cotton T-shirt is not a good candidate for sublimation: the result usually looks very dull or simply does not fix as it should. On rigid items, a “normal” mug or plaque without a sublimation coating can produce poor colours and low durability.

It is also common for certain plastics, varnished woods, untreated porous surfaces or unknown finishes not to give a consistent result. If you are not sure what the material is or whether it is prepared for sublimation, the professional approach is to confirm it before personalising.

Durability tips to make the result last

On suitable textiles, durability depends greatly on use and washing. To extend its life: wash inside out, avoid bleach/aggressive products and do not iron directly over the printed area. If it is a work garment or will be subjected to a lot of rubbing, it is worth considering whether sublimation is the right technique for that specific use.

For mugs and rigid items, the key is the quality of the substrate (coating) and daily use. To keep the finish for longer: avoid abrasives, hard scouring pads and impacts. If the product will be exposed to sunlight (for example, certain outdoor items), UV can also have an effect over time, as with any colour print.

Common mistakes when choosing a product for sublimation

• Buying a garment without confirming its composition: on cotton, the result does not fix as it should.
• Choosing “normal” rigid products without a sublimation coating and expecting vivid, durable colours.
• Trying to sublimate onto dark colours without taking into account that the technique does not print white and the background alters the design.
• Sending low-resolution images or poor-quality logos: the result is noticeable, especially in small text.
• Not defining the size and placement (print area) and discovering too late that the design does not fit the product properly.

Final professional recommendation

If you want to avoid incorrect purchases and surprises in the finish, the best approach is to validate the product first: textile composition, base colour and whether the rigid item is truly suitable for sublimation. With a photo, a product link or a sample, we can usually advise quickly and set realistic expectations for the result.

Check your product before personalising

If you have a product or garment and do not know whether it is compatible, write to us and we will review it with you before manufacturing. You can contact us by WhatsApp or send us the details and design via contact.
