Incorporating colorvision software color management with sil

[darkb2002]

How do i bring my calibrated monitor profile into silverfast HDR. After calibrating my monitor and applying this profie, do i just go into the CMS window, and apply "Image colour matching" in the internal monitor box. Is that it??
Also can i scan the calibration chart for calibrating the printer through the scanner, save, and then open up in HDR and make the profile in silver fast. Or will it make no diffrence if I just scan into photoshop, and do the profile there. How would I then set up my CMS profile in the Output/printer box.
At the moment i have my CMS profile set up as reccomended in Ian Lyons Computer Darkroom. Would these canges affect any other settings?
Hope some one can be of help
Regards
Kirk

You haven't indicated which type of pinter you have, but even then I doubt that using HDR is going to be of any help. Typically when you are creating a printer profile you scan the target image and then use the scan in the profiling application. It doesn't have a role within SilverFast Ai or HDR unless it is a Postscript type printer

Ian,

Have you had better luck creating profiles leaving IT8 Calibration On, or Off? I left it on in the older version of Profiler RGB and it worked great, but last night I tried it with v2.1, and had to do quite a bit of correction in Profiler RGB. I talked to George Rodart at ColorVision a few months ago, and he said to experiment and see what works best. I was just curious if you've done the same, and what your results were.

Thanks,

Ian A.

A lot of folk have found that scanning the target via an IT8 calibrated scanner path results in better printer profiles. A lot of folk have very great doubts as to how Profiler RGB can ever hope to make a printer profile if it doesn't know the characteristics of the scanner and so can't by definition determine with ANY degree of accuracy what the ACTUAL printed colours were. ColorVision have veil of secrecy over this, but with a little thought you can figure out their secret

My experience would suggest that calibrating the scanner can often help, but occasionally it can also produce VERY bad results. Experimentation appears to be the best route.

Hi.
Thanks for your replies. A few more queries and a bit more information. I am trying to build a profile for my Epson Photo 1290 Printer this will be the final output for the image.
The first question is: I want to make a printer profile in HDR, but Colour Vision don't give all the information for the HDR interface and I have found that they are very slow at answering my e-mails. When you're setting up HDR to scan the Colour Vision calibration chart in the Auto window in defaults, what setting do you put for colour cast removal and the midpip fixed target?
Once a profile has been made what settings in the internal:- output do you suggest? Do I put internal colour management instead fo RGB, as this will then open up the output/printer in the 'profiles for ICM' section of the window do I then put the new printer profile in that box?
Then I presume once you take the image in to Photoshop you would not convert to the working RGB for Photoshops internal colour management system.
Once I've sorted all this out and got the profile, in my eyes it does make more sense to leave the IT8 callibration on. I will post a reply and let you know how it goes.

You can't use HDR to make the scan as it depends on separate software for that purpose. You'll need to tell us what scanner software you use to make the intitial scan.

Cast removal, etc. are all irrelevant - you will NOT be using these features when creating a printer profile.

For Internal Output you choose RGB and NOTHING else. I think that you will only cause yourself more confusion by including your printer profile in HDR. You want well behaved RGB data out, not the VERY badly behaved RGB that is the result of a printer profile. With a desktop inkject printer you do NOT need to worry about the Internal Output setting - leave it at the default RGB

Hi ilyons

Thanks for your help. I`m using an Epson Perfection 1640 with the provided software to scan.
If I use the printer profile that I made with the scanner, do a scan, save, open up in HDR, I presume it has then lost the printing profile that was made in the scanner. If I then open it up in Photoshop, how is this affecting the way the image is printed to the callibration of HDR?
Can I make a printer callibration through HDR callibration?
Am I repeating myself?!?! Sorry if I'm going round in circles....
Regards,
Kirk

Kirk,

As I indicated in the earlier messages - HDR is not a part of the printer profiling equation.

You scan the printed target on your 1640 using Epsons software with the gamma set for the equal of 1.5 (epson value of around 80/90). You might find this tutorial helpful, although the epson driver version is slightly different.
