Tony,
My experience is that the Canon LIDE scanners are excellent for Profile Prism.
I have the cheapest one, and it works fine.
I do use Vuescan software with it, but I can't remember why.... perhaps the Twain driver didn't work with W7 64 bit, or something....
My scanner LIDE is very old and still works fine with PP.

I think Terry has a newer one. Maybe he will pop on.

A key advantage of Vuescan is that they keep updating it.  If you purchase the "Professional Version" you get unlimited updates.  This helps as Windows OS keeps changing and if you purchase a different scanner.

Hi Terry,

Looks like the 700F at £83.40 from this selection.

PS. I cannot believe the HP 2575, even with Vuescan is good enough from the test I have just done on a simple chart.

Tried it but it does not register as a RAW in QU. I can see and edit the file but Refine Raw is greyed out.

Before I buy that Canon scanner I thought I ought to send you (Fred and Terry) two files. They are coming across now.

One is a color chart that I used to make a print on my Epson 2400 with QU.

I then took that chart and scanned it on the HP 2575 with Vuescan. The scan may have other incorrections but the most obvious is that it is oversaturated. Maybe the Vuescan is set up wrongly. I am using the settings Mike suggests alongside the Canon section:-

Of course I have not yet got a version of Profile Prism to try the file on. Maybe it needs oversaturated files?

Assuming the HP is never going to work I'll buy this:-

The PP general advice on scanner settings is here btw. http://www.ddisoftware.com/prism/help/scanner.htm
An IT8 target in an international standard and has to made to a very high standard. The targets Mike supplies with PP are calibrated and the calibration numbers can be entered into PP.
The print from your own printer is of a special target image  unique to PP with 100's of colour patches.
A typical scan image of both targets is attached.
Terry

The official total of patches is 9,261 on the target image that you print using your printer.

The IT-8 target I believe has 228 color patches.
There are stringent guidelines for these targets, so much so, that they get a CHARGE number, or build number.
Then color corrections are tweaked into a text file  which Profile Prism accepts to match the target Charge number.
Now, the IT-8 is ready to use, and accurate.

The 9000 + color patches on the Printer target will produce a pattern that Profile Prism recognizes and which makes a Printer Profile to make your color as accurate as it can based on the color gamut of your printer.

***   Seriously, I make printer profiles for my HP Advanced Glossy. (Beautiful) But I don't have any HP profiles to compare...
On the other hand, one day Mike told me that he made a few profiles that were noticeably better than the commercial ones that ship / download with the Epson and Canon printers.

So I tried that on my Favorite paper; Epson Ultra Premium LUSTER!   
Shazam! Side by side, mine was better.
So I did my Ilford Smooth Gloss.  Again, the Profile Prism profile won.
I did my Ilford Pearl; same thing.

Not only are the results satisfying, but it's fun to learn and be able to "roll your own"
