I am currently testing an old software program that was designed, to allow very fast cropping of files and generating re sized files. For instance If I need an 8x10 it will crop to a 8x10 and create a new 8x10 file at 300dpi. The Master file is not touched. The problem with the software is the the newly generated file has no color profile attached to it (regardless of the master files profile, which is Adobe 1998).
My question is what command in PS will attach the profile correctly, assign or convert?
-
You have to Assign a profile. What profile is the big question.
-
The master file is a file that I am converting from raw to Tiff and I am doing the conversion in the Adobe 1998 color space.

What OS?
-
Win XP

Let Qimage do the entire job.

Let Lightroom do the entire job (including raw conversion).

For $35 ? :-) The originals had AdobeRGB attached so I guess there's no need for RAW development.

Hi Ernst,
The printing is done through Qimage. However cropping in Qimage is a pain. Does Qimage have a function to assign a profile automatically?

Don't care for lightroom.

Print to file. Use the printer profiling route and select AdobeRGB there as the output profile. That's when you start from the original with the AdoberGB assigned and have the crop done + profile assigned in Qimage
If you want to assign AdobeRGB to the files you already cropped (and lost their colorspace, I hope your program didn't do more than stripping the profile) then you should set the Qimage colorspace assigning to AdobeRGB (default is sRGB) and the printer profile = output profile to AdobeRGB. Or both to Adobe 1998 if that difference matters.
On the cropping, if it has to be done per image in a different way then it isn't the fastest route. But in batch mode, the output ratio aspect set and either an auto crop or auto on length adaption etc and resolution set at 300 PPI for instance it should do well.

Ernst,
Where in Qimage do you assign a profile to the file?

Qimage automatically assigns a profile to untagged images. All you have to do is to choose Adobe RGB for untagged images in Color Management Preferences, and print these images to files.
-
At the top of the color management box there is a way to assign the profile to untagged files. However I keep on selecting Adobe 1998 but it isn't showing up in that window.

Did you click on that window where the profile file path is described, you may only see the start of that path? I can change easily between any profile.

Ernst,
Your right its there. Just bad screen design :)
Why do I have to print to file? Can't I just print to printer like I always do?

If you want prints and are not bothered with the fact that your files have no colorspace assigned then you can print directly that way. AdobeRGB will be assigned and the conversion will be done to the printer profile specified. But it isn't what you asked for initially.
Next time you get unexpected errors in color management it could be files that have no AdoberGB assigned :-)
The default sRGB for assigning untagged files is a wise choice/best guess in practice. You may want to set Qimage back to that default.

The reason I want Adobe 1998 is because that is the color space that I am using on the original file (master) when I do the raw > Tif conversion. Then this cropping software is used on the Master file, and the software creates new files cropped properly but strips the adobe 1998 profile from it.

If you call them Master files and archive them then assign AdobeRGB 1998 to those files, you will never regret that extra step.
If you print and destroy the files right after that it may not be necessary.
The manual of Qimage and especially Learn by Example is a good guide the next time.

Ernst,
The printed files are not kept. The masters are the Original files that are converted from raw that have the color space embedded properly. Those are kept. I have looked at the learn by example tutorials for Qimage don't recall anything on assigning profiles to files.
