try this i have had good luck with this techneque(sp)
when you get the best scan you can do a very light gaussuen blur (.5
or less)this tends to remove most of the morea (sp) and speckels. start
small on the blur

Hi I am using a Mustek 800sp scanner, and Photoshop.

I am trying to scan magazines and have not been able to get a nice scan after
adjusting it with Photoshop.

A friend of mine owns a UMAX Se or is that S6? and when he scans ,his driver
allows him to select a filter (descreen) and that does the trick.

On the other hand I don't have a setting like that and am having trouble using
Photoshop to descreen , unspeckle and remove and Moire patterns.

I am a newbie at Photoshop and any help would be appreciated.

Thanks in advance

Danny

The basic process I use to remove moire patterns is to open up the file
and look at each channel (Red, Green, and Blue) - see the little dotty
patterns? Apply a Filter - Gaussian Blur - to each one individually,
JUST enough to make the dottiness less apparent, that'll usually do the
trick.

Try that

Better than using Gaussian Blur is the Dust and Scratches filter which
attempts to preserve edge integrity while blurring the rest of an image.
You'll never get great descreening results, but this tend to do the trick
for many image. Of course, you'll want to unsharp mask the image after
doing your editing.

Hi,
I am also a newbie to Photoshop, but may be able to help you out.
I'm not too sure what versions have what tools available. I am using version
3.0.5, and there is a filter called "despeckle" which does what you are trying
to do. It does a great job for me at making screened images look continous
toned.

Hope this helps,

Tim.

Yes, there is a perfect and simple solution for this:
Put a black piece of paper behind it.

-------------------------------
/ \ top of (flatbed) scanner
----------------------------------

---------------------------------- black paper

---------------------------------- original image

----------------------------------
I I
I I scanner
I I
I I
----------------------------------

My english is not good enough to explain it.The image on the back will
'shine through', but so will al the black.

A simple trick I use to prevent 'see-trough' is to use a black paper
behind the original when I scan. Not high-tech, but efficient.

The best trick I've found is to use the image->adjust->brightness
Darkness and "burn" out any show though. Move the brightness bar to
the left until the back ground is gone, and move the contrast bar over
to strengthen your picture.

Another method is to choose Noise - Dust&Scratches with a pixel radius of 1.
