Ok, I received the files. Actually they both are pretty close. I will also warn you, that depending on what color profiles the printer uses, humidity when printing and even the paper type, quality and coating will ultimately change the final color output of the covers. On top of, the first cover may not look exactly like the last cover. These are all issues we encounter in off-set and web (type of printing, not the internet) printing. Unless you are running color comps during the middle of the job, and matching ink swatches (which some printers do for large and important jobs), printing this way is kind of a finetooth crapshoot. You have to go into with a "close enough" attitude. I do this everyday and have just come to accept the drawbacks of mass printing. All you can really do is provide the printer with your best copy and then hope they do their job.
As far as your files go, follow the steps below:
1) Edit > Convert to Profile. Change Destination Space to "Custom CMYK".
2) In the Custom popup, change the following
2a) Ink Colors: SWOP (Coated)
2b) Dot Gain: Curves (We'll gain back some contrast here)
- Click the Cyan radio button and change 50: 78%
- Click the Magenta radio button and change 50: 69%
- Click the Black radio button and change 50: 72%
3) Separation Type: GCR
4) Black Generation: Custom and then drag the high-point dot a smidge to the right. Per the image below:
5) Black Ink Limit: 100
6) Total Ink Limit 300
7) UCA Amount: 0
8) Click OK to return to the "Convert to Profile" window
9) Engine: Adobe (ACE)
10) Intent: Relative Colorimetric
11) Make sure both are check marked: "Use Black Point Compensation" and "Use Dither"
12) Click OK.
13) Go to File > Save As
14) Change the "Save As:" name as necessary
15) Change the "Where:" location as necessary
16) Format: Photoshop PDF
17) The only thing that should be checked is "Embed Color Profile: SWOP (Coated), Curves..."
18) Click Save
19) "The settings you choose" popup is a warning box. I think you can feel free to choose "Don't show again" by now here.
20) In the "Save Adobe PDF" popup window, make sure Adobe PDF Preset: is set to "[Press Quality] (Modified)"
21) Standard: None
22) Compatibility: Acrobat 5 (PDF 1.4)
23) Under Options, uncheck everything, but mark "View PDF After Saving"
24) Click Output in the left window.
25) Under Color > Color Conversion: Choose, "No Conversion"
26) Make sure Profile Inclusion Policy is set to "Include Destination Profile"
27) Click "Save PDF"
The saved pdf should open in your pdf reading program. This color conversion should be optimal for printing. What do you think?
