Hi, so I saw the Y2K Fusion shop on Instagram a few weeks ago—you know, those visuals with holographic butterflies and those classic 2000s pink-and-blue gradients—and I got the idea to try recreating that aesthetic using sublimation printing on polyester fabric. I got the PNG files from a client (someone who wanted T-shirts in that style), and well, the result is really not what I was hoping for... the purples turned into a pretty ugly burgundy, and the silver tones have almost disappeared. I feel like my ICC profile is completely off for this type of design, especially with the metallic or iridescent colors that are typical of the Y2K Fusion aesthetic. Is the problem with the transfer paper or the profile? Because with other, flatter designs, I get decent results on the same press. Has anyone else struggled with holographic or iridescent designs like this?

I am not familiar with with the ink sets that would be needed for this.
What inks are you using?
