More and more adaptable materials and improved inks are being developed, allowing companies to offer unique and attractive products. With technological advancement, it is likely that sublimation will continue to evolve, providing new opportunities and creative solutions in the access control sector and beyond.

The sublimation process

The process begins with the selection of special inks that contain pigments designed to sublimate. These inks are fundamental, as they are the ones that turn into vapor when exposed to high temperatures. A printing device that uses this technique prints the desired image on a coated sheet of paper that is compatible with the process. This first step is crucial, as it ensures that the colors are vibrant and accurate before being transferred.

Once the image has been printed, the next step involves placing the paper on the base material, which can be an access card, a piece of clothing, or any other suitable surface. By applying heat and pressure in a controlled manner, the sublimation process is activated. The ink particles turn into vapor, penetrate the fibers of the material, and solidify as they cool. This molecular bond creates an image that is an integral part of the object, rather than simply being on the surface.

Precision in temperature and transfer time are essential elements to achieve a high-quality final product. Each material has its own specifications, and it is important to consider these details to avoid errors that could affect the image. Most industrial applications leverage computers that control these parameters to ensure consistent and satisfactory results in each production batch.

Once the transfer is complete, the final product is evaluated to ensure it meets quality standards. The durability of the image and its resistance to fading are rigorously tested. Sublimated products, such as access cards, not only offer a professional finish but are also functional and durable, making them a preferred choice for modern identification systems.

Phases of the sublimation process

The first step in this innovative process involves the preparation of the materials. Special inks containing a sublimation agent are selected, along with coated paper. This paper allows the ink to be effectively transferred to the final material. The quality of the inputs is crucial, as it determines the accuracy and fidelity of the colors that will be reproduced in the final product.

The printing phase is essential and is carried out using printers specifically designed for sublimation. During this stage, the design is printed on coated paper, where the ink settles in thin layers that will allow for the subsequent transformation into vapor. It is important that the printing is done with high resolution to capture all the details and nuances of the design, ensuring a vibrant image that will be reflected in the final object.

Once the printing is completed, the transfer process begins, one of the most critical stages. The printed paper is placed on the material intended to receive the image, and heat and pressure are applied using a heat press. This combination causes the ink to sublimate and penetrate the material, creating a lasting bond. The temperature and time conditions must be carefully controlled to ensure that the process is effective and that the image is properly fixed.

Finally, after the transfer, the material is allowed to cool, allowing the ink to solidify in its new state. This phase is crucial to ensure that the image maintains its quality and durability. When all phases are completed properly, the result is a sublimated product that is not only visually appealing but also wear-resistant, providing durability and a professional finish suitable for applications in access control and other customized uses.
