Big problem when i print in Greyscale

[olleolle]

Hi,

When i print a picture in grayscale it seems not to be good.
It looks it print in all colors anyways, and look very blue and a littlebit yellow.


I tried to change from RGB to Greyscale in Photoshop CS6 and also choose grayscale in
the printer driver. But somehow it looks bad anyway.


Can someone please give me any advice on this ??

I have the following printer: Epson WP-4015 and i printing on Sublimation Film from http://sublideck.com/sublimation-3dfilm.html

Thanks!

Do you have the same problem using sublimation paper as opposed to the film?
