How do I lock colours to CMYK

[Katiee]

Hi everyone,

I have just started to use Affinity publisher. And my biggest problem is that text colours keep changing to RGB (or HSL) even I have changed it to CMYK. So how can these be locked to stay CMYK?

I also have few pictures that I need to be Greyscaled. Do I need a different application to do this or can I do it with Publisher?

Hi @Katiee

Welcome to the forum. 

If you set the Colour panel preference to 'Sliders' and enable the lock this will set all objects to use CMYK. 

If you follow the link below this should provide further information.

Another alternative to set images to Greyscale is to select 'K only' on the context toolbar, whilst the image is selected. This option will only appear on CMYK based documents

Thank you so much 🙂
