Prints are light no darks

My prints are all printing light no dark tones. I have done a nozzle check and cleaning all are working.
Reloaded QTR and piezography curves still no darks.
Any ideas?

Please post the following info so I can help:

Your printer.
The inkset you have in it.
What shade you have placed in each channel.
The name of the curve you are printing with.
An image of the nozzle check (I still need to verify it)
An image of the light print.

I can’t help with anything really until I know this info . . .
