Hmm, try setting your PSD file to 'multiply' in the effects palette. Has the same effect I think
- hmm didnt try that. thought that was a screen effectdeathboy
- comes out the same on overprinting preview but before printing maybe you'll get a rip from your printer to checkmekk
- ha that works looking at the seperations. didnt expect thatdeathboy
- tehehemekk
- yea probably best to check. but looks solid. The PDF has the plate info. Never really messed with varnishs so not much xpdeathboy
- thanks save the time from copying and pasting multiple elements and creating new files to get the same effectsdeathboy
- my bank account nuber is: 680...mekk
- ha! i have like three litecoins, that might make 50 centsdeathboy
- titcoins, please!mekk
- ha! for fucks sakes that shit is real! Of ocurse why have coins when pornhub is free and there is http://qbn.com/topic…deathboy

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

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

Firstly, as has been said, overprinting is not an effect, it is simply letting the transparency of the ink show through when overlaid, combining to create colours on the printed page, rather than before printing inside the computer.
An overlay will tell the computer what colour to make, then this will be printed as a simulation of that colour, but the printer won't print solid colours on top of each other to make it.In your diagram above, I think the reason you have a double stroke around the right hand cirlce is an issue of trapping. Trapping is the 'safe zone' that printers build in when two colours are going to sit side by side. Since it is almost impossible to align two blocks of colour side by side (you either get an overlap or a white gap) printers take the attitude that deliberate, controllable overlap is better than a white gap. The navy blue inner circle shows the overlap or trapping between the cyan and magenta plates.
- trapping normally is 0.088 mm, not 6 points as the line in the above example?stewart
- the printer WILL print solid colors over each other in overprinting. This explanation is confusing even ME because it might be wrongmonospaced

Another problem with multiply is that you can exceed your ink limits without realising it causing muddy shadows or lines to appear a little thicker than you wanted.

good link here that discusses Multiply vs Overprint:

wow just wow, i'm a junior and the lack of understanding of this is amazing, i was explaining over print stoke for a die lie the other day to another junior and their all like, i don't really need to do that its just to make the file perfect and tidy arrgggg. who teaching these people?
- sorry rant over, says the know it all junior, i know all love them haclimbatree

the above multiplied objects give a perfect color seperation in the PDF output preview after exporting to a fullcolor PDF from InDesign.
anyone with an example where this multiply effect really goes wrong when bringing the document to print? i'm still trying to sort out why I shouldn't use multiply.
- Talk to your printer and/or get a proof. If Multiply works for you, then that's great and now you know for surehellobotto

My hypothesis comes back to my original point that Overprinting is a printing technique and Multiply is a screen effect.

Wow this thread is really useful!

@stewart
Over printing inks is not equivalent to multiply, so it's really pointless to talk about them like they achieve the same effect, or to say that one is illogical and unpredictable. Some inks are naturally more opaque than others, so results in real overprinting do vary in many ways, including the stock you're printing on. hellobotto got it right up there.
- I know, I know, but somethimes the outcome is really illogical. Problem is that I can't explain the examples that good in English.stewart

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

"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:

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

Thanks for that but maybe I didn't explain it well. I see you got two seperate plates looking the same, through indesign and photoshop... maybe im missing something... What I have is a rasterized image with transparency. That image i was hoping to apply on top of other indesign vectors/images with a overprint effect. So it doesnt knock out the shit below it. The overfill doesnt seem to work like it does with vector objects in indesign. Maybe there isnt a way to make it work, but what i did was just copy and paste the images out of indesign in their placements and do all the path work in photoshop. It would be awesome if indesign could force overprint on rasterized images because than i wouldnt have to do it like 7 times for different shit.
heybuddy.tv/temp/ex.pdf is what i did through photoshop but couldnt do in indesign. Basically the checkered flag is a psd and that kept knocking out the purple behind it because i couldnt force an overprint like a vector graphic.

^ If you place a PSD in InDesign, it appears as rasterized image even if you have vectors inside of it.
There are multiple workarounds:
1: Flat your figure in the PSD file to one layer with transparent background, then make a color fill layer with a clipping mask, 100% black (not #000, but C0 M0 Y0 B100) then convert it to a greyscale image and then convert it to a duplex with one full-tone color. Tell the printer to use that color as varnish.2. If you have the vector elements, copy them to your InDesign file and give it a new full tone color.
With 1 your InDesign Colors should look like this:
With 2 make sure to select 'full tone' when making the new color.
Also your new full-tone colors must appear in Acrobat, if not, you done something wrong.

fuck it. ill do it the PSD route. Would be nice to know if there was a way to have indesign sort it out though for future reference
- deathboy0
So i have this varnish layer that is a PSD file. I cant not get it to overprint indesign CC 2014. Not sure if the problem is its a PSD or what. All vector elements work fine. Any help would be great.
