I don't see any setting in the scanning software for descreening.

Here are a few recent examples:

According to this document

there is a setting "descreen".

Here are your scans with the Descreen function ON, simulated in Photoshop:

Thanks. I never thought to look in my HP Solution Center for additional scan settings, or anything for that matter. I thought that it was just a "help" section. I bookmarked it. Thanks again! I will try a scan with the new modified settings to see if they come in clearer.

Just my opinion, but I think the mags that I recently scanned are not good quality pictures to begin with. Some I have are really bad, thin papered crap! I installed 4 GB of RAM [3.8 actually] just for scanning, so I hope once I get the hang of doing good consistent scans, I will be posting a lot more, at least that's the plan anyways.

UPDATE: I just tried scanning a pictorial with the new scan settings. WOW! What a huge difference! I had to adjust the size and dpi settings a few times, but I got exactly what I was looking for! It takes slightly longer, but I figured that.

Thanks very much everyone for the help! I got 600 mags that need scanning. I doubt I will get to all of them, but at least I can do the favorites for now.

It sounds like you are using too much resolution and definetly too much filtering/sharpening. Try 200dpi, no sharpening of any kind. Go easy on the descreen too. See if that helps. if it does go easy using unsharp mask or other sharpening. If you have sharpening off, all i can say is all in ones are often lame.

Thanks, but I figured it out. When I went into my HP Solution Center, I found an area where I can change my scan settings/preferences. One simple click on 'scan at maximum pixel depth' was all it was! A HUGE difference! It's like clear as day. I wish I knew about that setting a few years ago. Luckily, though, I only did like 4 pictorials since I bought this all in one, so not much loss of time and effort. Yeah, I agree 100% about no sharpening. BIG difference when you don't sharpen the scan at all. 'Cause even if it needs to be sharpened, you can always use Gimp, Photoshop, or whatever the scanner software has. Trial and error, trial and error.

A question: if a picture is a two page layout, how do you scan? Will the scan software let you merge both pages to create the one pic since you have to scan each page seperatly? Thanks!

Yes, Photoshop (of course!) can do that for you. But the quality may be not as good as expected since it relies on the quality of the scanned pictures.
I normally fix that myself because I was not satisfied with the results.

I normally disassemble the mag, scan the double pages and then fix them using different layers and fix the gaps that occur from layout and printing of the mag.

If you have further questions let me know!

Cheers,

hartwig, what do you mean by different layers? Also, do most scanning software allow you to merge two seperate scans? Thanks from a newbie!!
