Sublimation color problem, Epson L1250

[loniu26s]

Hello, I'm writing about a certain issue that has been bothering me for the past week. At work, we use Epson L1250 printers with regular sublimation inks. We don't have access to an ICC color profile. In short, I would like to achieve a 1:1 effect. We work in CorelDRAW, and the templates are in RGB. The colors appear more reddish. We don't have much time to individually adjust the colors and saturation of each design to ensure satisfactory printing. Where can I find the golden mean? Is it in the color profiles, the paper we sublimate on, or could there be an issue with the printer? If I missed any details, please comment, and I'll clarify. Got some preview of the last projects in attachments.

You're wasting your time without the correct ICC profile, can the inks supplier not give you access to this?

Received a .zip file with all the instructions and ICC profiles from this company. Fingers crossed that it will work :)

Should've contacted the ink company first before posting here :) They provided me with a correct ICC profiles and printer settings.
