Updated: I got access to a second scanner to compare the calibration to ensure consistancy accross scanners:

Raw Epson scanner output:

So other than the Epson being a much better scanner, calibration does ensure consistancy :-)

Still working on it but heres a cover using my current scan settings:

That should definitely be added to the guide with the corrected you can tell it's sky blue in the background and not that purplish blue. But how much did that cost you looking at the prices I've seen between $40 to $100 for it. Though I went through the first 10 pages only.

I got mine off ebay for $15 I'd look there first. I don't know about shipping but there's a German company that sells them for $10.00. http://www.targets.coloraid.de/ Any IT8.7 reflective target will work. The Q-60 is the kodak number for their IT8.7 targets.

IT8.7 Wikipedia page

The corrected image looks much more like the original. It is indeed a blue sky not a purplish one.

Hopefully that program works with my old Compaq S200 lol.

Images updated.

Method:
Scan at 600 dpi (no color correction)
Appy color profile
Apply Descreen 4.0 filter ($20 for the home version)
resize to 300 dpi using "bicubic sharper"
Fix damage with rubber stamp tool
save as png (large but better than tiff while still being lossless).

Note for archival purposes 300 dpi makes sense as the halftone screen frequency is 145lpi therefore 300dpi is just over twice the screen resolution. The res nees to be more that the halftone resolution because of the non-halftone parts of the image (playstation logos/ text).
