Up till now I have not used colour profiles on any of my printing and I have found the colours fantastic, Is there any reason to change and start using profiles.
I design my images in PS2019 and corel draw. When I have designed the images I save them as jpeg and print from the folder in which the file is saved via the context menu. I print on high quality setting and on the appropriate paper type.

My sub mugs look great colour is no issue, My t-shirts the same. I print on 3g jet opaque for darks and the light garment paper in this collection.

Thanks in advance
