Dye sublimation is a fantastic personalization technique, as it allows you to produce personalized gifts with the highest quality image and a fantastic finish for a minimal investment. A4 dye sublimation printer in Pakistan allow you to produce a wide range of personalized products for your business, as we explained in a previous article.

It is clear that you can print t-shirts with your sublimation printer but they have to be made of polyester and white or light in color . And what happens when you want to print a cotton or dark colored T-shirt? In this post I am going to propose several solutions for printing dark cotton t-shirts with your sublimation equipment.

Sublimation takes place in 2 steps :

  1. First of all you have to print your design on sublimation paper using your sublimation printer equipped with sublimation inks and
  2. secondly, you have to apply heat and pressure with a transfer iron to transfer the design from the paper to the shirt or sublimable object.

In the second stage, sublimation itself takes place – a chemical process in which the ink applied to the printed paper is converted into a gas and, under the influence of heat and pressure, penetrates the polyester fiber. Therefore, in order for the fabric to be dyed, it must have a polyester content of at least 67%. The higher the polyester content, the better the printing results and durability.

Another important detail that you should take into account is that in sublimation printer in Pakistan the color of the printed design is added to the background color of the fabric. So a white fabric is the ideal support to sublimate. We can also use light or pastel colors, knowing that the final result will be slightly affected by the background color.

After this explanation, it is clear that the ideal shirt to print by sublimation is the technical shirt (100% polyester) in white , but you can also print cotton-touch sublimation shirts in white or pastel colors.

Sublimable T-shirts

However, the deeper we get into the custom t-shirt business, the more likely we will have a need to print cotton t-shirts and dark-colored t-shirts . We can do it, understanding that these solutions that we are going to propose are not comparable to the quality of sublimation on white polyester. They are the best solutions for printing dark shirts without having to invest in new equipment.
