how to get the best scan
Without spending an arm and leg for a scanner.
I went and got the hp PSC 1315v psc=printer, scanner, copier] all in one. It does all three, and the only gripe so far was some banding [someone called Moire] on some magazine scans. Without a magnifying glass, it's not real noticeable. But it is there. I'm thinking I have a bargain scanner, and the default settings may be the best I can hope for. Couple things I did change on an image below Output type: Millions of Colors Output dimensions: 1358 x 1975 pixels File Size: 7.86MB Resolution: 200dpi Scale: 100% was the sharpening from medium to none resolution from 200 all the way to 1200 with and without de screen. And the 1200 res came up to 1.2 gigs after scanning. From the smallest 200 res no sharpen, no de screen to the 1200 res sharpen medium, de screen there wasn't really that much visible difference to waste the time scanning above the defaults. Is there anything else I might be able to try to get these scans to look more like the originals in the magazines. -- more pix @ http://members.toast.net/cbminfo/index.html |

You can eliminate (or at least minimize) that with a little "post production" work in a photo editing program like paintshop pro or photoshop. Even the cheap $50 photo editors (and a few freeware ones) have moire removal or "soften" features. It's basically a slight blurring of the image. On newer printers with "moire correction" features, it's usually done the same way via the driver. The difference being that the photo editor programs tend to do a better job and are ALWAYS faster. You aren't missing much without this particular feature. Another trick you can use for scanning magazines that helps a lot is to slip a piece of black paper behind the page you're scanning. It helps prevent "bleed through" of the text and images from the opposite side and the following page. --------------------------------------------- MCheu |
