So I went to mpix.com as advised and I setup their ICC profiles under the custom setting as instructed by their PDF (and I have my monitor calibrated). I then duplicated the image in photoshop and did a split screen. On the left I had my original image and on the right I had the duplicate. To the duplicate I applied the mpix.com custom proof settings. Once I did, the duplicate image with the mpix settings looked very washed out as compared to the original. So at this point in the workflow do I now go and edit this duplicate image so that it looks good on my screen? Will this mean that it's matched up for my monitor and their printer? Thank you.
