First, let me say thanks for the good work you're doing. I have checked many filters and many methods of removing moire, and your descreen filter - quality wise - is plain simply the best.

I only have two problems I'd like to ask you about:

1. Scanning a single page, then waiting a couple of minutes until the descreen is done is, well, boring. I would prefer to scan everything without descreen, then apply Desreen filter to all scans via any kind of batching system. It can be stand-alone (i.e. not connected to the scanning software) filter, whatever, just so I can scan all pages, then descreen all pages at once (even if it takes hours). Do you have or are working on anything like that?

2. Descreen filter takes 100% of processor power. So not only it takes a couple of minutes, it also makes the work on the PC nearly impossible. Would be really great to be able to set the process priority to low. Yes, it'll take longer, but at least I would be able to use the PC meanwhile.

FYI, my PC is Athlon 4000+, 2 GB RAM, using latest SilverFast - updated online what I got with my EPSON Perfection 4990 Photo.

Dear StStRt

it might be a start to use not more than 600 DPI when descreening. Almost all screens will be able to be detected and higher resolutions won't give you more details.
What can be suggested is doing raw (HDR) scans with SilverFast Ai and then descreen them using the JobManager tool in a HDR or DCPro.

To get you there as fast as possible it is exactly the idea to use your computer's strengths. What's the point in using a high speed CPU, but then only half its capability? If you want to do other work meanwhile, you want to check out the Windows task manager, and set a lower process priority to SilverFast.

ad1) I am actually scanning at 300 dpi. I assume SF does 600 dpi internally and then scales down to 300. Anyway, thanks for the suggestion. I have actually found a solution that satisfies me and does exactly what I need (external PS filter from www.descreen.net), but now I can try to start comparing the two.

ad2) "The point" is to be able to use the PC (even if for browsing the web) while something is going on in the background. SF makes it even almost impossible to list files in a folder, looks not like "normal" priorioty, but nearly "exclusive". Anyway, good to know I can mess with its priority through Task Manager, let's hope that'll turn out to be stable.
