I know that this topic is supposed to be closed (;^)) but I should like to add a few last remarks about print-ready (or press-ready?) documents.
I think that SP3 can produce print-ready documents with some technical knowledges/skills: if you look at the first post of this topic, you'll see that jcolome doesn't know what is a CMYK image, how to choose a CMYK color from the Apple Color pane and so, how to produce a full CMYK pdf ready to be printed (@jcolome: of course this is absolutely not a critic, we all have something to learn!)
Without a basic set of knowledge and skills, you can easily produce "messy" documents even if using XPress or inDesign (how to print correctly black made of C=M=Y=B=100%?).
That being said, let try to answer to these questions (all solutions use basic applications/tools that are provided by Apple with all versions of OS X (at least from 10.6.x)):#1
. How to set color of text using CMYK color mode: use the CMYK sliders of the Color pane and don't forget to select one of the CMYK profiles. Nothing complicated here!#2
. How to set fill and stroke/line colors of shapes (vector objects) using CMYK colors: use the CMYK sliders [â€¦] One more time, nothing really impossible here!#3
. How to add images and be able to produce CMYK PDF documents?
Several ways are possible here:A
: Use images that are already CMYK ones.
How can I verify that? Open them in Preview, display the inspector, select the first tab from the left and look at the bottom of the pane:
This is a CMYK image (a tif image with a resolution of 300 dpi and embedding a Generic CMYK color profile).
This is not
a CMYK image but a RGB one (tif, 300dpi, Generic RGB profile).
If your images are already CMYK ones, no conversion is needed and you can add them to your documents (I'm not talking here about resolution/size, this is a completely different "problem").
But, what if these images are not CMYK ones? Look at the "B" solution(s)!B
My images are not CMYK ones!
One more time, two (I mean three) different solutions:
- Don't care about this, leaving your printer makes the work for you (see axys' and MJBS' posts).
Of course, you have to find a printer that accepts to do this if possible freely or at a modest price.
Also, this is certainly more complicated with on-line printer using only email and phone to communicate.
- add them in your documents w/o conversion (so as RVB images) then convert the whole document when exporting from SP3 or by creating a second version of the PDF file with a little help from Quartz filter and Automator (keep cool, nothing really difficult! ;^)).
This way you have an original PDF version and another one, "fully CMYK", ready to be printed.
- a last solution would be to convert them to CMYK before adding them in your document:
Preview can't convert RGB images to CMYK ones (at least using 10.6.x/10.7.x, I don't use 10.8 and so, I have no idea of what Preview is capable).
So you need to use a little Automator workflow/application that convert RGB images to CMYK ones for you.
This seems appealing but, in fact, there're numerous steps that make it difficult to use and even more difficult to explain.
This works perfectly and I have to say that, most of the time, this is the solution I use.
So, keep concentrate on the first or second solutions:
- the first one is the easiestâ€¦ once you found the right printer!
- the second one is slightly technically more complicated but you keep the control of what you send to print because you can adjust what is produced by the Quartz filter and Automator application (you can use different CMYK profiles, add more conversions (set images resolutionâ€¦)
A SP3 document with three elements:
Two of them use CMYK colors: text and rectangular shape (black background), the third one is an RGB image.
The next step is to export this document to PDF (don't forget to set bleed and cut marks (hirondelles in French) if needed).
Here what I get (screenshot from the preflight tool of Acrobat Pro):
As you can see, all color informations are kept (RGB image and CMYK colors for text and shape).
After processing this pdf file through the mysterious and magical Quartz filter/Automator application, I get this:
Note that the image is now a CMYK one with a Generic CMYK profile.
As an external solution (not included in SP3) this makes it an ideal solution for existing (or future) PDF files coming from any application (from BeLight or not).
I'll start another topic about creating Quartz filters and using Automator.
A last word, I should really thank Siouxsie for her patience! ;^)
Hope this helps.
