Questions about Color Calibrating Scanner With VueScan

[Alan Smithee]

Bear with me. I don't own an IT8 target. I borrowed one a while back. I
scanned it using Epson Scan's "No Color Correction" option turning off all
adjustments. It's a tiff file about 16M. When I looked at the scan on my
calibrated monitor it looked exactly like the IT8 card.
I want to profile my scanner using VueScan.
In VueScan I select Task: "Profile Scanner".
Source: I select "File" and point it at the target file I scanned earlier.
I hit Preview and the IT8 appears. (VueScan's color correction is set to
"None")
Great so far to so good.
I continue with the VueScan "Profile Scanner" workflow....
The correct Scanner.IT8 description file for the IT8 target is in the
VueScan directory as it should be.

The problem is when I go to the Color Tab in VueScan and change "Scanner
Color Space" from "Built In" to "ICC Profile". (without doing this the
program won't create the "Scanner.icc" file.) As soon as I change Scanner
Color Space to ICC the image in the VueScan Preview window changes color
slightly...like the color space has changed to something less vivid. When I
try to switch the Scanner Color Space back to "Built-in" the IT8 image in
VueScan's preview window does not change back to its original hue.
Can someone give me the run down on their workflow for profiling a scanner
with VueScan.

Sorry but You that's wrong way.
That target wont scan, specially with Epson Scan.
It only prescan and with VueScan.
There is step by step manual on VueScan help, read it.

And remember, that profil work only when You use VueScan.

Use Generic Color Negative and Advanced workflow (see manual).

Sorry when profiling a scanner these options are not available.

So a borrowed one is somehow inferior to buying one.

Read the original post. "No color correction" "No Profile"., therefore I'm
using a Vanilla Epson driver the same one VueScan uses to generate an
original copy of the IT8 target.

I'm faking out the program by feeding it an original file of an IT8 made on
my scanner. It works, this is not the problem, the problem is a color shift
and the scanner.icc file not creating itself. Try it out and tell me
otherwise. If you not willing to try the problem don't bother trying to
help.
