Custom Colors convert to CMYK automatically, when Gaussian Blur is applied in Illustrator

[melvinanorman99]

Hi everyone, spot colour Gaussian blur does not print out when doing separations. How I can fix this?

It seems this issue was already reported here:

Custom Colors convert to CMYK automatically, when we set "Effect->Blur->Gaussian Blur" 

Sorry, but I have no further informations.

I think it's already fixed.

(at least on my Windows machine ;-))

Not yet fixed on Mac Illustrator 24.2.3.

If you need this , install an older version

As Ton mentioned, the bug is still there on Mac OS.

A workaround that works is the old-fashioned way that one once had to go at the time when Illustrator didn't support spot colours in conjunction with raster effects at all. For example:

- Draw a black filled circle (or with shades of grey).
- Apply the Gaussian Blur effect.
- Behind that circle draw a (slightly) larger path (circle, rectangle etc.) and fill it with the spot colour.
- Select both objects, go to the Transparency palette and create a clipped and inverted opacity mask.

Check the result with the Separation preview palette.

Certainly no ideal solution, but you may take that route, at least until the bug is fixed.
