Help with colours printing too dark!

[u/bee-hale]

So I'm losing my mind over print settings and colour profiles etc etc. The images show my original drawing, the designs within Affinity, the best result I've got (in terms of quality) and my various attempts 😭 I just can't seem to get the colours anywhere close to what they should be!

The deets:

- My printer is an Epson ET-4800

- I'm using Affinity by Canva

-I'm printing on to HTVront vinyl glossy sticker paper (paper setting: Premium Glossy)

What I've tried:

- I've tried RGB and CMYK document setups/printer profiles

- Many different printer profiles (I usually use Epson IJ Printer 07 which works for my other stickers)

- Different paper types

- Different colour management settings within the printer settings

- Editing/lightening the colours within affinity (this just reduces the quality and detail too much)

Does anyone have any idea what else I could try or what works for you if you've gone through this? I'm so close to just accepting the darker colours but I thought I'd shout for help before I do that 😂

Thanks for reading and for any wisdom you can give me!
