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

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.
I made an example for you to download here: https://www.wetransfer.com/downl…

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

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.

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

Use multiply if you're not overprinting! This is getting ridiculous.
Overprinting is LITERALLY printing one color over another. For example, printing a spot light blue over black, or vice versa. Sometimes that color does well on top of black, which is NOTHING like multiply.
Multiply is a filter popularized in old-school photoshops, and then in Photoshop. It just adds the color values together on screen and creates a new color. It's something you use to get that desired effect, but it should never be confused with or compared to overprinting.

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

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

If you are wanting to create the effect you're demonstrating in your Multiply example, but with overprinting, then you have to accept this print production technique (like playing with dot gain) might not offer you a shortcut. You have to deliberately create artwork to generate your end result.
This goes for anything related to creative problem solving. In order to execute any concept, grand or small, you have to work within the limitations of the processes propelling the activity. Assuming Multiply will translate on press is foolish, consulting with a pressmen and knowing Multiply will translate on their presses is being a smart designer.
One last thought. Take a step back, and replace Multiply with Difference. Both of these effects live in the same family, they are blending effects. Should we expect to be able to replicate "Difference" with etched plates on a 4/C press?

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

looks like trapping problems

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

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

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.
