Scanner Question

[johnmiic]

Suppose I scan pics from a mainstream magazine. When I get the image it contains artifacts of the printing process, (screen and printing patterns). How do I eliminate these from the image completely? Is there a software add for Photoshop that fixes this?

There are different descreening methods you can try - most of them use PS various filters to slightly blur parts of the image so the patterns are blended out. My scanner has a descreening filter in the driver that does a pretty decent job most the time.

Otherwise I usually have to experiment a bit depending on the image source. This is a reasonable and easy method: Remove Moire Patterns From Scanned Photos in Photoshop and Elements

Here's another different technique: http://www.dbphoto.net/techniques/moire/index.html

The best and fastest solution might be to borrow a scanner that can descreen right from the start - or maybe your scanner can do it, but it's hidden in the settings someplace?

Hmmmm....

It depends on your scanner, your scanning software and your image editing software. An easy fix, try scanning at lower resolution. (100dpi or so.) If you're not doing a lot of resizing it might work for whatever you need it for.

'Course; that's another factor: the end result will depend on what you're doing with it. (Found that out the hard way: scanned a pic at high resolution 'cos I had to resize it, and it looked good on screen but when I had it printed the printer caught the grain of the paper; making the result look weathered.)

That's a good point - but I assume he wants to put the images online.

If you're printing it I'd try without doing anything at first - from a magazine it will probably look fine, he probably won't get moire and anything you do will loose sharpness.

I'm still using Mac Classic Tech. OS 9.2.2 and a Microtek Scanmaker X6 with Adobe Ph L.E. 2.5.1. I just want to save the images-not post them. I have many dated SF mags from the `90's and the have good reference shots of actors and SPFX, etc. I've been scanning at as high a rez as I can and re-sizing the image after. Sometimes the resize compresses the patterns and they won't show. Mostly not tho.
