A4 Scanners

ComSoft6128 · 08:01, 04 February 18

Hi,

I am looking at scanning a number of A4 MicroDesign pages. These pages are the originals from 25 years ago and are black and white. They have been kept in plastic sleeves and aside from some slight yellowing at the edges are in good condition. From having had a look at various sites it looks like 600 DPI would be the minimum resolution required. Does anyone have any experience in scanning in old prints or can anyone recommend a low cost scanner for this job?

Cheers,

Peter

If you are scanning only documents, any cheap Epson scanner will do.

In case you'd like to scan pcbs too, then go for HP Scanjet 3670, G2410 or similar models, as they can scan non-planar surfaces quite good (see the pcb scans from the mainboard versions page), and they are very cheap (5€ in a second hand shop, mind you...).

Indeed for documents any old printer will do; software is more important than hardware in this case. 600dpi should be more than enough!

I was told at my local printers that 250 dpi is good quality, so any more is not really going to do anything extra for old prints

I usually scan everything at 300dpi and occasionally 600dpi if I need more detail.

I think newspapers are printed at 150lpi (lines-per-inch) and magazines at 300dpi. But of course when you scan old magazines you also have displays in mind. So 300-600dpi should be enough, surely?

For any scanning involving lots of pages, anything above 300dpi ends up with huge file sizes. 300dpi is enough to create realistic reproductions. I use a cheap Canon Lide 25 that I got for €20 on ebay. It's flat enough to store it between books on the bookshelf too.

Oh, that's the one that's powered through a single USB, isn't it? Still have one propped sideways next to my desk!

Yup, another advantage of this scanner. The last thing I need is yet another generic PSU with a special connector just for the scanner.

Thanks for the replies.

They have helped to clarify that for me.
The Canon LiDE 220 also runs from USB, that might be the way forward.

Cheers,

Mine is sitting idle, for a while now. If anyone wants it for such a project, it's yours for the postage.

Hi Gryzor,

As you can imagine, I would be more than interested in your kind offer.

Cheers,

Peter

And just in case you are a Linux head like myself... It's fully supported by XSane too
