I apply a red glow on an object (rectangle) on an black background.When exported as JPEG or PDF, the red glow color faded become greyish. I check that it's same when I turn the proof colors on.I've change different modes for the drop shadow but none gives the correct result.
This only happens in CMYK mode. When exported as RGB, it's fine.
.
What transparency mode did you use?
I tried all, none gives the correct result in CMYK environment.
Use multiply mode and acrobat 6 or hoigher compatibility. Works fine for me.
The glow disappears in Multiply mode.
I try to attach a sample cdr file here but a simple file like that is 542KB.... =.= .
something like this?
Hi Ariel,
That's how it looks it with Proof color OFF.
These are my steps/settings:1. I create a new document, A4 size, CMYK, 300dpi.2. Create the full background rectangle, fill with black K100.3. Create a white rectangle, no outline.4. Apply drop shadow (Large glow, Opacity 100, Feather 20, Feathering Direction: Outside, Shadow Color: RED)If I set the Transparency Operation to Normal / Add / Difference) with the Proof color off [simulate environment = U.S. Web Coated (SWOP) v2], then it looks like the top row. But if I export the document as JPEG (CMYK) or PDF (CMYK), or turn Color Proof ON, it looks like the bottom row.
The problem si not the drop shadow, it's the background. You don't read my tutorial? I've writing about this years ago! hahaa btw, it's the same proble of any gradient. Create any object and apply a Fountain Fill (F11) from "red" to CMYK 100% black only. The result is wrong, because "red" fade to white and "Black" fade to white (or fade to gray). But if you add "red+black" isntead only pure black, the result looks very different...

I have bad memory....haha....The fact is I was not visiting the forum for an extended period between 2008-2010, could be missing out on your tutorial on this one.
Thanks for the solution.But I wonder why it appears OK with Proof color OFF, or when export as RGB.

In the tutorial about Mesh Fill included with CorelDRAW X4, I talk about this problem too

The RGB color mode will use Rick Black instead Pure Black, so there's no problem, The proof color try to show you the real image, as close is possible, according with your color profile. When you disable it, you don't see the difference.

Why?I expect the behaviour should be the same as in CMYK, i.e. "red" fade to white and "Black" fade to white, giving the same issue.
