Sublimation ink is a special type of ink used in sublimation printing. It is formulated with dyes that can transform from a solid to a gas without going through a liquid stage, allowing for vibrant and permanent prints during the sublimation process.

To print sublimation images, you need a sublimation printer, sublimation ink, sublimation transfer paper, and a heat press machine.

Firstly, the image is printed onto sublimation transfer paper using the sublimation printer and ink.

Then, the printed transfer paper is placed on the desired substrate, such as fabric or coated item, and heat pressed to transfer the ink design onto the material.

A sublimation printer is specifically designed to accommodate sublimation inks and transfer vibrant prints onto various materials. It uses heat to transform the sublimation ink into a gas, allowing it to permeate the surface of the substrate and create a permanent, full-color print.

For sublimation printing, you will need a few essential components: a sublimation printer, sublimation ink cartridges or bottles, compatible sublimation transfer paper, a heat press machine, and the desired substrates (polyester fabric, polymer-coated items, etc.). Additionally, you will need a computer with design software to create or edit your desired images or graphics.

Sublimation ink is primarily used for transferring designs onto polyester-based materials or items with a polyester-based coating. It is commonly employed in the production of custom apparel, such as t-shirts, hoodies, and jerseys. It is also used for personalized items like mugs, mousepads, phone cases, and other products where vibrant and durable full-color prints are desired.

To make sublimation prints brighter:

1. Opt for high-quality sublimation printer machines.
2. Use white or light-colored polyester fabric.
3. Ensure using  transfer paper for sublimation of good quality.
4. Use high-quality sublimation printing inks.
5. Optimize printer settings for color saturation.
6. Maintain proper heat press settings.
7. Pre-press fabric before printing.
8. Perform post-pressing to enhance brightness.
9. Handle and store prints carefully to prevent fading.
