Now that we’ve covered printer settings, let’s discuss another major player in sublimation printing: the ink. Sublimation inks appear duller on paper before pressing and only show their true vibrancy after being transferred onto a sublimation-ready surface such as 100% polyester fabric. Special sublimation ink should be used for sublimation printing as it is designed to look lighter and duller before transfer but vibrant after proper application.

For a bright and vivid outcome in sublimation printing, always transfer your image to the most white and bright side of the substrate.

Choosing the Right Sublimation Ink

Choosing the right sublimation ink is crucial for achieving the most vibrant and accurate colors in sublimation printing projects. Using the recommended ink, such as Hiipoo Ink for Epson EcoTank printers, can prevent poor color output and damage to your printer.

Remember, sublimation ink appears lighter and duller before being transferred, and its true printed colors become visible only after pressing onto a compatible material.
