I downloaded the ICC profile from the local printer I am going to use. I want to make sure that I am doing the right thing.
Here is what i have tried:
I have noticed a problem with red shifting hue.
I duplicated the image so that I could view the original and compare it to the proof.
With the duplicate. I went to the menu view> proof setup>custom> selected the ICC i downloaded from my local printing company.
This makes the image on the screen show the proof colors.
I then went into the hue/saturation and adjusted the shifted colors until they look close to the colors of the original.
However, when I turn off the proof colors and just look at it in sRGB , the reds look oversaturated.
I am not sure I am doing this right.
Will it print correctly for the reds?
I'm no expert, but from what I've learned I think you should use Edit > Convert to Profile to convert the image to the printer profile. The color management will change the color values accordingly while trying to preserve the look as much as possible.
If I understand correctly what you did is a manual color correction as an alternative to what color management is suppose to do automatically by Convert to Profile. Of course you can do both, Convert and if necessary still color correct manually.
When you color edit only based on Soft Proofing, you should also make sure that the color values are not further altered by color management and send the file untagged to the target device. This is because soft proofing simulates how the current pixel values like RGB will be reproduced on the target (in your case - printer).
Alternatively to soft proofing and sending untagged image, you can choose Edit > Assign the printer profile to the image and while the pixel values won't change, they will be displayed the same as if using soft proofing with the printer profile.
As digitaldog already suggested, if you and the lab don't work in accordance with each other regarding color management nothing can be predictable
I hope this helps and doesn't confuse you.
