Hi Tyler, What are you trying to achieve? Are you trying to build a workflow that will allow you to visualize the printed page on a display? Do you want to build a workflow that allows you to print a page on an inkjet printer to simulate what will print in the book? If they are looking for Adobe RGB images, they probably have a link profile that maps the ARGB to their printer device space using some arbitrary form of gamut mapping and tonal response. This would not necessarily be a standard ICC profile. If they are using a standard ICC workflow, they should be able to send you an output profile which you could use for simulation in photoshop. I don't think that sending a target tagged as ADOBE RGB would buy you too much because the color management is already concatenated into a single transformation. The problem that you have here is that the output data is already mapped through a transformation so the gamut mapping is already in place. I don't think a profile produced with this data will necessarily yield good simulation results. You are essentially trying to profile a system that is applying gamut mapping to the output data. Not a good idea. Send some test images and visually evaluate their process.

I am starting occasional work with one of the POD book publishers. They are one of the better ones and the work looks good, but obviously it gets down to file prep. Their process details are unknown to me, though they state a lot of ongoing calibration including color management. I choose not to push for info about that, and demonstrate respect for their stated expertise. They offer test prints, and I mentioned I may slip in a profile chart, they expressed no concern about that. So far they are asking for color prepped in AdobeRGB and tagged as such. Since I have no idea what conversions are going on between tagged RGB and ink on paper there's no real way for me to determine device color. So, if I send an RGB chart in as a color test, tagged AdobeRGB so it is treated exactly as images would be, how can I make the best use of the resulting profile? For example, can I use it to soft proof using "preserve numbers" while prepping ARGB files? Since it will be a profile made from a chart that was converted from AdobeRGB at their end, it seems there would be a missing step using it for file prep that will limit usefulness... I realize I could push for more info that may result in a more useful profile but I know what it's like to have clients talking to me like they know more about what I do and I, so prefer not to go there for now...
