I have both Vuescan and the Canon software that came with the Lide 210. For those of you that have both programs, which do you use for printer profiling? I have both set up so I can use Twain import via 32 bit Photoshop 5.1 on a 64 bit PC. When I try to setup with Vuescan twain I don't have the output options recommended in the Prism help file. I don't have any file type options on the output tab. When I open Vuescan itself outside of Photoshop I see all the file formats including "raw file type" and "48 bit RGB". Should I not bother with Photoshop twain import?

If the Canon software is preferred are the settings posted somewhere?

I've used Profile Prism sucessfully in the past but I don't use it very often. Now with a new PC, scanner and software I'm trying to avoid the trial and error approach while setting up a new standard protocol .

Thanks for your help.

Hi,
Code:
I don't have any file type options on the output tab.
For some reason all the options are not visible when Vuescan is accessed via Twain.
Open Vuescan direct; twain is not really necessary when using Vuescan anyway.
See screen shots attached for settings; the multiple passes is optional but I've found I getter a better PP messages result doing that - experiment yourself.

Vuescan. Originally with Prism target got exposure 247, 24X, Printer target exp 241, 12X. I didn't have any white border on the printer target so I cut a piece of the blank photo paper and included in scan. Then for Prism target got exp 230, 21X, for Printer target exp 223, 2X.  I then used 8 scans and your set up. Prism target exp 234, 10X, Printer target exp 228, 2X. I think it is the multiple scans that helped. In no case were any grays clipped.

Probably not necessary but I reprinted the printer target so I can cut it with a 1/8 inch white boarder and will make the final profile.  Should I be concerned about Exposure being only around 230, or 10X's on the Prism Target?

Thanks, Bob

The printer target does have dotted cut lines around it so a white border is not required.

I think PP will tell you if it's under exposed. Eliminating the white border may help to increase the exposure a little. Are you using a black card over the targets on the scanner platen to screen the white surface of the scanner lid? I think that is essential; it need to fit the platen completely.
I don't think 10 X's is anything to worry about.

Yes, I'm using the black background. I cut out a new print target with about 1/16 inch white around it. Prism target exp 244, 9x, -- Print target exp 249, 7x no gray clipped. Generated profile. Printed test image that comes with Profile Prism. Prints in general and skin tones look very good. One obvious difference from profiles I've generated using version 8 is that the color gradients go less to red at the ends than they did before. Don't know if this is due to 8 vs 8.4 or some other factor.

I was following the thread concerning printing using Perceptual vs Relative Colorometric rendering so tried RC for the first time. With RC rendering ends of gradients go to red and overall saturation is increased dramatically. Will have to try on real life prints.

Thanks

Hi Bob,
As a matter of interest, what paper are you profiling and which printer?

I'm profiling Costco Kirkland Glossy photo paper for the Epson R1900.
