Scans not matching original

[PhotoJenics]

I am having color problems with my scan and can’t figure out why. This is both when importing into PS and using as a standalone. I have tried different combinations of settings that I’ve seen in previous posts, and all are yielding the same result: Everything scanned through Silverfast is too bluish and unsaturated looking, both on my calibtrated monitor (Spyder 2 Pro) and printer (Epson paper profiles).
I’m using SilverFast Ai with an Epson v750 Pro calibrated with Monaco. Color photos are not as noticeable, but any black & whites/sepias turn out looking extremely bad. I’m scanning 48>24 Bit Colour. Please help me with suggestions for my SilverFast CMS and General settings, or anything else that may help.

I currently have the following settings for CMS:
Input>Internal: ICM
Internal>Monitor: ICM
Internal>Output: RGB
Scanner: my custom scanner profile
Internal: Adobe RGB 1998 (Same in PhotoShop)
Rendering Intent: I’ve used both Perceptual and Rel. Col.
Profile is embedded.

Settings for General Tab:
Colour Model: RGB
UM: inch
DR: 2 pixel
Default: SilverFast Defaults
Interpolation: Anti-Aliased
HR prescan: 1x
Gamma Gradation: I’ve used 1.6, 1.8, 2.0.
Q-Factor: 1.5

Dear Photojenics

Could you please provide us with more info like SilverFast version you are using (6, 6.2, 6.4, 6.6, etc) also some screenshots and endscan would be useful.

Thank you very much for your further help

I’m using Silverfast Ai version 6.6.0r3a, and I have attached a file that has 3 photos showing originals and scans.

Dear PhotoJenics,

Could you please provide us with some information like, what kind of material is that you have uploaded? is it reflective or transparencies, posssitive or negative?
How did you get the original into digital form?
Did you scan that with other application?

Do you scan in 24 bits or 48 bits, which tools do you use in SilverFast, do you use automatic color correction? to you use NegaFix? any kind of Filters?

Which scanning resolution do you use?

Thanks for your cooperation

These are all reflective (positive), and the two water photos were taken by my cameras (tree with Canon Powershot, and Beach with Nikon D60). The photo of the girl (left) was originally scanned in with Silverfast being imported into PS, but edited using PS2 to get it to more closely match the original photo. I then printed and scanned this edited version for you to see (the photo on the right is this scan).

All were printed on my Epson Perfection R2400 using Epson paper profiles. I let PS determine the colors and had ICM selected for Color Management, as well as Off (No Color Adjustment) by my printer. (I should note that when I have files sent to outside printers, they come back looking like what I can produce on my printer.) I then scanned them in to compare to the original.

I scan 48->24 Bit Colour, no color collection, and Auto Sharpen for my filter. With reflective scans, which are 95% of my work, I use 300 dpi.

Thanks

Dear PhotoJenics,

This slight differences when scanning reflective material are normal, you have to think of all parameters involved in this, you have a printed copy of your picture, the paper has certain characteristics which the eye can see but your scanner can not as well as your computer monitor can not reproduce (e.g. if your pictures are printed in glossy surface, your eye perceives much more brightness and contrast which can not be either captured nor reproduce by the machine).
Also when scanning a paper copy, you have a glass surface between your picture and the sensor of the scannner, this glass surface also affects (modifies) your scanned pictures to a certain degree.
It is normal to have this little differences.

Did you use Monaco to profile the scanner for the specific paper and ink that you are using ?
Make sure the ink has dried for 24 hrs before you profile. i have seen slight color shifts from this.
Also, make sure the scanner has equilibrated for 20-30 minutes before you scan.

Even with all of that ok, you will still see some differences since scanning, printing , and scanning again is a positive feedback loop and will accentuate small discrepancies in the profiles.

The blue cast might also be from the optical brighteners in the paper, especially if they are not based on titanium dioxide.

If the blue shift is consistent, you can correct that with a custom curve or you can try the color cast removal tool or you can edit the profile if you have the tools.
The lack of saturation is not unusual for reflectives.
