Icm profiles in photoshop

[Holden Caulfield]

Hi, I would like a bit of help…
I am a little confused about icm profiles, as a competent user of Photoshop and having a high quality calibrated monitor I have decided to experiment with my local photo finisher who provides icm profiles for the Fuji paper used on the Fuji Frontera system.
I edit down my images from raw format using Adobe srgb colour space then before saving I select the Icm profile supplied by the photo finisher , at which point the colour of the image notably the green content changes .
My question is :- By saving the image to the photofinishers Icm profile does the colour gamut move out of the calibrated range of my monitor, if so how can I be sure that the saved image matches what I see on the screen when editing in srgb ?

A supplementary question is :- Should I be editing my images in the colour profile of my photofinisher as opposed to working in Adobe srgb. then selecting the icm profile of my photofinisher before saving?

I have done quite a lot of research on line but cannot get my head around this, any help appreciated

First things first.

Adobe RGB or sRGB? Adobe sRGB doesn't exist.

You can use the proofing tool to simulate how the image will look on another device and double check that nothing bad will happen to the colours but it's a simulation to be used as a guide, not a perfect representation. The chances are the printer's gamut is smaller than your monitors so you're likely to lose colours on the print that you see on screen - that's why proofing is useful.

What you should be doing depends on how the printer is handling colours, best ask for and take their advice on how to best prep for printing with them

First aply your profil by going to Edit and the down to Assign Profile and select your Fuji Frontera profile
Next
Go to View and select Proofing setup and select your ICC (International Colour Consortium)/ICM profile
Now you can see how the colours will be when printed.

Sorry but Chaz you seem to have a basic misunderstanding of how colour management in Photoshop works.

By default Photoshop reads the monitor profile from the system and manages the image colours so they look correct on your screen - it translates the working space colours (sRGB) to the monitor_profile.icm

When you proof colours photoshop emulates the target device on your monitor by doing another translation.

Assigning the device profile to the image and then proofing in the same profile is disabling colour management because you're saying the image and the output device use the same colour space so no translation is needed.

I know we've covered this before and you weren't convinced, I'm sorry but you do seem to have the wrong end of the colour management stick and I don't know how to explain it any better.

pxl8 is correct. The profile that has been provided by your finisher gives the characteristics of the printer, and is used for "soft proofing". You should keep the colour space you edit in to one of the standard ones. In this case I would suggest sRGB as Adobe RGB would be much larger than the Frontier could reproduce. This way you would get a more accurate representation of the final print.

Using the Frontier profile as a working space will give some unpredictable results.
