I'm new to inDesign, and I'm currently designing a book cover, for which I need some special effects. I'll try to explain as best as I can.
The background is rich black, on top of it I have a text in white (all over it). I applied a block with 80% opacity, in rich black color. I cut out some shapes in it. The point was to have the text in dark gray all over the book cover, but in white in the places where I have the shapes.
Everything is working exactly like I want, but a friend of mine told me if I apply rich black over white, I'll get a kind of magenta gray, so I have to apply pure 100 K to avoid that and get the dark gray I want. I tried that, and of course, applying some pure black block on top of my rich black cover gives all the cover a "grayish black" look. How can I work around that? I tried setting my semi-transparent block to "darken", but it didn't change anything.
I put the links to the pdf, I hope that's ok.
That's the one with rich black: https://dl.dropboxusercontent.com/u/68049919/coverlayout_print_richbla ck.pdf
and that's how it looks with the pure black: https://dl.dropboxusercontent.com/u/68049919/coverlayout_print.pdf
Thanks a lot!
If it's slightly warm, then it's ok I was afraid it would be bright magenta ^^ My rich black settings are C=50, M=40, Y=30 and K=100. I wanted something warm, so go with the artwork. Should I lower the magenta value a bit?
I'll try doing that, thanks!
Also, one more thing: I'm getting a weird white stroke around my illustration. I imported it as a psd doc with a transparent background (I tried it with a png as well) and I got the weird halo when I exported it to pdf. I read on the internet that it sometimes happens with pdf and transparent backgrounds, but I'm afraid it will print like that. I tried printing it on my own printer, but it's just an inkjet printer and the fact that the halo didn't print doesn't guarantee a good result in the end... Do you think the halo will disappear? Have you had some stuff like that happen to you before?
Thanks a lot!
I noticed that. too, and wasn't sure if it was intentional. Try a TIFF. See Screen Artifacts on Transparent PSDs in Exported PDFs Can Be Deceiving…Most of the Time. | InDesignSecrets
Oh, I tried with TIFF already, and I couldn't get the transparency to work.
But I finally redid my image, this time using the alpha channel, and I think I'm getting somewhere. I also lowered the magenta value to 30 instead of 40. My gray letters are supposed to be very dark, almost black, so I guess even if there is a faint magenta tint, it will not really show.
Here is the new file: https://dl.dropboxusercontent.com/u/68049919/coverlayoutalpha_richblac k.pdf
Thanks for your advice!
The screen on the travel laptop I'm using at the moment hasn't been calibrated in awhile, but I think the new mix may hve swung over to the cooler side -- a little heavy on the cyan compared to the magenta and yellow. It should be a bit higher, but 20% is probably more difference than necessary. This is, of course, entirely a matter of personal taste, but I liked the other mix better with the hair color.
I wouldn't say the gray letters are almost black, either.
It looks like you have a K-only layer included, too, that has a samller knockout. I'm seeing a strip of k-only gray along the knockout edge when I zoom in.
Oh, yes, I forgot that the background for the text was in pure black. I fixed it, is it okay now? I also raised the magenta to 35. I've been told the gray letters will print much darker, so I'm trying to get an effect in which they are more like a texture. https://dl.dropboxusercontent.com/u/68049919/coverlayoutalpha_richblac k2.pdf
This is super strange... And I don't know how to get rid of it :/
Edit: oh, 84% K is actually my semi-transparent block... Or at least I guess? My opacity is at 84%. But it's rich black, not pure black. No idea what happened here or how to remove it.
I think it must be the drop shadow, because I remember kind of trying it and not wanting it anymore, but now I can't find it anywhere. It's very difficult for me to use the separation preview, because it's my first time and I don't really understand how to use it. I see it, but I don't know what to do with it or how to find out where it is exactly.
EDIT: I think I found out! For some weird reason, my stroke color was set to pure black. I got rid of the stroke color, which I don't need anyway. Is it fixed? https://dl.dropboxusercontent.com/u/68049919/coverlayoutalpha_richblac k2.pdf
Thanks a lot, you were really helpful! So now you think my dark gray will really be dark, or will be a kind of dark magenta? ^^ It will be my first time printing something (other from printing stuff on my own printer, of course) and I really need the letters to be dark, but not so dark you can read them, and dark enough so that they don't disturb the rest of the cover (like the titles, for exemple).
I'm back... Turns out the problem is my semi-transparent bloc is not printing as overprint, so it kinda knocks out the other colors underneath. Problem, because overprinting is selected in the preference panel, and I also checked it on the Attributes -> overprint.
Why is that so?
There's no need to use transparency to create your background text color—just make a text frame filled with the rich black then select the type and fill it with an 80% tint of the rich black swatch or any other gray mix. Like this:
The text frame selected with its fill showing in the Colors panel:
Here the text is selected and the Colors panel shows the text fill as an 80% tint of the rich black. There's no transparency in this case.
In general it's bad practice to use transparency when you can get the same effect with color fills.
Also if you are worried about the neutrality of the gray check with your printer on whether the gray text should be 4-color (your 80% tint) or straight black (95% black).
The accuracy of the InDesign softproof depends on an accurate monitor profile and the assigned CMYK profile (Edit>Assign Profiles...). The assigned CMYK profile affects the preview including the profiled gray balance. For example the default SWOP CMYK profile previews your 4-color dark gray bluer and as a lighter value than US Sheetfed.

Thanks a lot! Actually, I just solved my problem, using a trick so simple I'm ashamed to have spent so many hours on that...
I made my text 90% pure black (on no background, the background is on another layer). I copied it. I made my triangular shape. I copied the text into it. I selected the text inside the triangle. I applied a white color to it, et voila! https://dl.dropboxusercontent.com/u/68049919/testcouvnew.pdf
I guess now I'm good No problem with rich black showing through the letters, no problem with the transparency, no problem with overprinting (I made sure to uncheck the overprinting on the dark gray text layout).
And the transparency was there only because of the triangle and the text inside it Now it's gone ^^
Rob, your method is a bit tricky to implement given the triangle shapes involved and two-color lettering along the borders.
And in my opinion, a 4-color text is goingg to look alot better in print than a screened K-only on a book cover.
I agree that the background should be a 4-color rich black.
Setting the type as a 4-color (43|34|24|85) vs. black only 0|0|0|93 has some potential problems. 43|34|24|85 should be neutral or close to it if the press gray balance is right, so including a mix with CMY shouldn't change the gray neutrality—0|0|0|93 should look close to or the same as 43|34|24|85.
However, if the press goes off balance—maybe the press operator thinks there's too much magenta in the skin tones—then holding back on magenta will push the 43|34|24|85 version towards green, but would have no affect on the 0|0|0|93 gray.
If the color wants to be warmer than neutral I think there's too much cyan in the CMYK mix—the extra 10% cyan typically compensates for the browness of eqaul parts CMY.
