  5. Re: Howtek 8000 Drum vs. Epson V850 flatbed scanners

    I also agreee totally. It is totally true that the Epson is way less capable than the Howtek, the Creos and the Scanmate. Simply see resolving power ratings in the 2019 side by side... no doubt !!!

  6. Re: Howtek 8000 Drum vs. Epson V850 flatbed scanners

    This is identical, all scans made by Pali, two Creos, Drum(bottom-right) and an Epson(top-left).

    Where is the difference ?

    Have you a criterion to say what's identical or you even lack this?...
