+1 this thread...
brought a tear to my eye
it's good to know there are still print people hanging about on qbn.

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.

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

^ 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.

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.

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

- 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

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

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

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

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

"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.

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

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

nice one Gnash. moar!

@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.

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.

looks like trapping problems
