CMYK documents, black not matching between vector objects and pixel brush

[NotMyFault]

Steps to reproduce

1. create new CMYK document (print ready, DIN A4)
2. Add pixel layer
3. choose brush tool
4. choose default black swatch (rich black)
5. paint a big stroke
6. choose rectangle shape
7. choose default black swatch
8. create rectangle that touches pixel strokes.
9. see that both black do not match. Brush is K-only and lighter.

Expected:

swatch should create identical colors for vector objects and pixel brushed

observed:

black does not match

I think it's the same on Win/Mac.

It seems that the paint brush automatically reduce C100M100Y100K100 to C72M68Y67K88.

Interesting "phenomenon":

To match the 100-100-100-100 of the vector shape as closely as possible, the brush color must be 100-100-99-99.

Hi @NotMyFault,

Thanks for your report and our sincerest apologies for the delayed response here. We are exceptionally busy following the release of V2 and we thank you for your continued patience and understanding here.

I can confirm I'm able to replicate this on iPad & I'm seeing the same behaviour that loukash has mentioned -

Therefore I'm logging this with our devs now

I'm not seeing this behaviour on macOS or Windows, but do note that the colour wells switch when changing tools from a vector shape to the Paint Brush tool, which might cause the 'change' you're seeing in colour. When painting in 100,100,100,100 on Desktop, the colour matches the rectangle filled with 100,100,100,100 for me.

Are you able to provide a screen recording of the issue on desktop, if you are still able to replicate this please?

The issue "[iPad] Paint Brush Tool using 100,100,100,100 CMYK values doesn't paint the same colour as a vector object using the same values" (REF: AFP-5738) has been fixed by the developers in build "2.1.0.1799".

This fix is in the current customer release.
If you still experience this problem once you are using that build version (or later) please reply to this thread including @Serif Info Bot to notify us

[NotMyFault]

No, still unfixed in V2.1

This time: create RGB document, and set color in CMYK color panel.

Thanks for letting us know @NotMyFault - the issue has been marked as fixed as the original report was regarding a CMYK document, not an RGB file - and the steps provided in that report are confirmed as resolved.

However, I have tested this with an RGB file also, using the CMYK slider and both the Rectangle and Paint Brush stroke appear the same colour for me, across multiple iPads.

Can you please expand on the result you're seeing and the steps you're taking?

Hi Dan,

i get the old bug in both situations:

• rgb doc with cmyk color
• cmyk doc with rgb color

rgb cmyk mismatch v210.afphoto cmyk rgb mismatch v210.afphoto

Hi again,

 

probably I was mixing up two issues.

 

This seems actually solved, but only for "default" black color swatch.
