I am surprised at how different software gives different results. I have an Epson 4870 scanner. I was never very happy with the standard Epson software but when I changed my computer operating system to Linux, I downloaded Xsane scanner software.
I can get much better results with Xsane than I could with Epson's software. I don't doubt that it's possible to equal the results, it's just that I can easily get good results now and I couldn't before.
