RGB CMYK PDF EXPORT.(colour conversion) Keeping your colours vibrant and your blacks black.

Question

Ive been tearing my hair out for the best part of 14 hours trying to figure out how to keep the closest possible conversion for working with images(rgb in photoshop) right the way through a work flow until exporting to print (having used the image in Indesign).  Here is the process I have been trying to get right.
1) working with RGB photo images in photoshop and converting them to CMYK (whilst holding on to as much colour as poss)
2) Importing them to Indesign and retaining the correct colours while working with them)
3) Exporting to high quality print and having all your colours stay 100% the same as you saw them within indesign.
I believe I have the solution so I posted my settings below to see if its the best way of doing things and to help others who might be having the same problems.
The problem
The problem is that there are many different colour models/profiles (both in RGB and CMYK) and each program can effect how the next one handles and stores colour.  It can become frustrating knowing where to go in order to set the settings correctly  as the combination of things to consider can make it confusing.
I understand many other people have similar problems and finding RGB blacks come out as grey.  CMYK spaces get converted from one type to another either from one program to the next or even as things move around one program (causing all sorts of wonderful,colour errors)  Plus you have imported colour profiles, working colour profiles and export profiles.  All of which can interact and effect each other) So getting it all consistent is key other wise colours change and get washed out.   Especially vibrant colours like greens and blues. they fade etc.
Through sheer trial and error and perciverance I found a combination of settings that worked well for me.
Since I am not an expert I wanted to post up my settings to:
1) see if this is the best way of doing things.
2) Other people may find them useful if they had the same problems I had,
The Solution
In photoshop
Save the photoshop image in CMYK by selecting:
Edit > Convert to prfile.
(in destination space)
select: Euroscale Coated v2   (I think this holds the colours the truest of all CMYK colour formats.)
(in conversion options)
  - Engine: Adobe ACE
  - Intent: Perceptual.
  - Check Use black point Compensation.
(leave all else unchecked)
Save the image ready to place in indesign (place rather than copy and paste.).
In Indesign
edit > colour settings   (make sure you click on the advanced tick box to open more options)
  - Working space: =
  - RGB:  sRGB IEC....
  - CMYK Euroscale coated v2
  - RGB & CMYK convert to working space.
  - Engine Adobe ACE
  - Perceptual
  - Use black point compensation
edit > Assign profiles
  - RGB profile. > Assign current workspace: sRGB IE
  - CMYK > Assign current work space Euroscale Coated V2
  - Solid colour intent : preceptual
  - Default image intent
  - After blending intent:  Perceptual.
edit > convert to profile.  (use similar as above).
edit > Preferences > Apprearance of black
  - on screen / export : Display all blacks as enriched black
  - Priniting and export : Display all blacks as enriched black
Overprint: (not checked)
------ when exporting to PDF ----------
File > Export
in GENERAL TAB
  - Adobe PDF preset: High quality print.
  - Standard (drop down menu): PDF/X-42008
  - Compatability: Acrobat 5 PDF1:4
in OUTPUT
  - COlour conversion: Convert to destination
  - Destination:  Working CMYK Euroscale Coated v2
in PDF/X
  - Output intent profile name: Working CMYK - Euroscale Coated v2
also:
If you are having problems with fill blacks not coming out as proper black then use registration instead of black from the swatch panel.
The above may seem either obvious to most of you or possibly not the best way of doing things but since the results worked for me and I found them tough to arrive at, it may be of use to others hence my post.
I would like your feedback on this process, have I done something wrong / could do better?  If so please let me know.  I am keen to improve.

Answer 1

I would copy and paste into InDesign forum. Text should stay 100% black. Any other black (like solid boxes or thick lines), I usually use a rich black swatch I created at 40/40/40/100. Looks 10 times better than just 100% black.
