How to get Adobe RGB (1998) as an output/printer profile?

[stevekale]

It has been suggested to me that I should maintain the broadest possible color space for my film scans (and Photoshop work prior to printing) and that Adobe RGB (1998) is recommended. The problem I have is that while this is available for Internal it does not appear as an option under Output/Printer. Hence I am not able to embed it in the scan which is passed to Photoshop and I must convert the color space at the end of the import stage. Can this be altered so that Adobe RGB (1998) can appear as an Output/Printer option?

I have also noticed a massive increase in print quality if I convert a B&W scan's embedded profile from Generic to Dot Gain 20%. How can I scan using Dot Gain 20% in the first place as it is not an available option on the drop down menu?

I am using Silverfast AI v6 and a Mac Powerbook G4 with OS X 10.2

It isn't avialable because it isn't a printer/output profile. You need only ensure that it set as the Internal profile and enbed profile is checked. This means that the image will be saved/exported with Adobe RGB 1998 is embedded. What you do after that for your printer is done in Photoshop or your RIP

Thanks very much, this was very useful. Can you also help me with the second part of my question with scanning B&W negs. Under "Gray" in Silverfast the only option I have is Generic Gray Profile.icc. (I have not yet attempted to create a custom gray profile for my Epson 2450 Photo using the Gray card.) I have found that using Dot Gain 20% for my gray working space in Photoshop dramatically improves results (although I would like to know a lot more as to why this is the case). Yet because this is not an option in the Gray drop down menu in Silverfast I have to convert each document at the end of the scan (not that this is such a big deal but I am trying to learn how to do this stuff correctly).
