I've found Share For Review (SFR) becoming an integral part of proofing artwork to clients, but one thing I've noticed is the difficulty that SFR has with accurately displaying (within reasonable tolerance) Pantone Colours.
This colour problem I only get with AI files; InDesign files have no issue and Pantones colours in these show in SFR just as they do in InDesign.
The colour reproduction problem is not limited to Chrome or Mac; this has also been viewed in Safari and Firefox, as well as all three browsers on PC.
Clients are advised on-screen colours are not 100% accurate and can differ from print colours; however in the screen shot attached this variance is far beyond reasonable and cannot be considered representative. I have to convert all colours to CMYK before sharing to work around this, but it means I'm duplicating all master files to do so.
As shown, the AI working file is in a CMYK colour space; client information and review link redacted from screen shot for GDPR purposes.
