I'm trying to create a mask from the Black channel of CMYK image.
The main color is a 0/0/0/100 so I expect the black percentage of the Black channel to be 100%.
And it is not. It is 92%.
Why is it so ?
Can you upload this file please. Can you post your color management settings please? Application and document.
Here is the colour management (in french):
Application : Photopaint 2020
OS: Win10
File:
upload.disroot.org/.../XPao2CP6
Hi David, I'm not sure to know what to send you. Is this a screen capture ? An export of something ?
Is this this screen ?
You need to scrool down on the application default settings and show me the rest of the dialog please.
Hi, Thanks for trying to help me.Here is the 2 screenshots again. In English this time.
CMYK to RGB
I looked at his file and the functions are correct. The action he's taking is not one that would or should induce a color conversion. While clicking this check box resolves this issue for this file there is something else that's incorrect with Draw internally, be it a corruption, a setting and if memory serves there was a past issue with default printer drivers.
In any case this setting can and will seriously create very poor conversions in many images.
