@hellobotto above:
I noticed that too using %'s of swatches. The outcome can be totally illogical and unpredictable.
With effect > multiply the outcome is totally clear. I still wonder why this should be for screen only and useless for print.

As a follow-up to the Stroke observation above, and a cautionary note about overprints...
If a 4/C object (A) is set to overprint another 4/C object (B), the CMYK values in Object A can override the CMYK values in Object B. For example, if Object B has a magenta value of 50%, and Object A has magenta set at 40%, the overlap won't look like 90% magenta (like Multiply would lead you to believe); the net overprint result is 40% magenta when printed.
This is why it's imperative to know how each behave and when it makes sense to use them. Sadly I learned this lesson...on press.
- exactly, because printing more magenta on top of magenta results only in magentamonospaced

Those are the answers i'm looking for.
Another example: when I have an object with a stroke, and I set attributes to 'overprint stroke', it only overprints the outside half of the stroke, not the whole stroke.
The whole stroke shows in overprint when I use effects > multiply > stroke only. Strange?- It's because the stroke my be "centered" over the edge of the fill.hellobotto
- Change the stroke to "inside" and see if you get the same effect.hellobotto
- nope, centre, inside, outside: all the same!stewart
- Interesting. Just saw this in Illustrator, too.hellobotto

"Multiply" is a screen effect. "Overprint" is a printing reference. If you're staying in the realm of screen-based artwork, then Multiply and its faux overprint effect is sufficient. If you're looking to get something printed, and your print bureau doesn't care to understand what effect you're trying to achieve, then using Multiply in place of Overprint could leave you sorely disappointed with the finished product.

Here is an example of Overprint in InDesign
and how to export InDesign file to a PDF using overprint option:

Isn't Black always set to overprint?
- Are all strokes black?i_monk
- Always?i_monk
- In everything?i_monk
- Process black is sometimes set to overprint by default because no printer...hellobotto
- ...wants to try to trap a 1pt thick black line.hellobotto

Just because it looks right on the screen doesn't mean it will print that way. Paper ≠ the web.

If you're using spot colours, your multiply effect will not print properly, first of all.
And doesn't overprint fill mean it's printed on a second pass in the printer?
- No, "overprint fill" doesn't mean "printed on a second pass."hellobotto

In Indesign, why would i still use the 'overprint fill' attributes (window>output>attributes) when i can use the multiply-effect on a stroke or fill of an object?
When I just use the multiply-effect I don't have to use the 'overprint preview' to check the overprint colors.
Is there somewhere a benefit of using 'overprint fill'? Or are these remains of an other desktop-publishing-era.
