The Epson software included with the scanner should be using Epson's own canned profile for that scanner, so unless it is not doing so, or unless there is something very unusual about your scanner compared with the standard unit, improper profiling should not be the cause of the problem. You should of course have your monitor profiled as well, but more than that, make sure Epson Scan is using that profile, if there is a way to control it. I don't use Epson Scan so I'm not sure. SilverFast does have very accessible colour management controls in its Preferences, and you can download from the SilverFast website a trial version (I suggest trying Ai Studio) to see whether it will help. You cannot make a custom profile from SilverFast using their Auto-IT8 feature unless you buy the license, but don't let that deter you. It will automatically detect and use their canned profile for that scanner model. Your main interest is to make sure you can configure its colour management and image editing controls to produce a good scan with their profile in the first instance.
