    Posted: 12 May 2019 at 10:08
I'm a collector of brochures and sales leaflets and in the next few years could be selling most if not all of these on. Before I do that however, I'd like to create digital copies of them all and will invest in an a4 flatbed scanner of some type.

Firstly does anyone have any suggestions for such a scanner, USB connected, a4 size that works well with windows 10?

Secondly, for decent quality scans, would you store the images in jpeg, tiff. Pdf or something else?

It's a big long term project as there are a few thousand brochures to work on but I'm looking for advice before spending any cash.

Thanks.

I'm partial to Epson scanners. Love their scanning software and the quality of output. I've had a V500 with the optional document feeder for years.

For brochures you could instead consider a different type of scanner that pulls paper between two scanning heads simultaneously. I recently bought an Epson FastFoto FF-640, primarily for scanning photo prints; but it does a great job with any type of flexible paper. It's blindingly fast, doing both sides of a page in a single pass, and allowing multiple pages to be stacked for input. You could do a mountain of brochures in a single day with that.

I scan to JPEG, high quality, perfect for my needs.

JPEG compression is rather awful for any artificial line art including letters shapes.

TIFF is just container. The ".JPG" EXIF from your camera is a TIFF. TIFF's can also use various lossless compression schemes--LZW and ZIP being the options in Photoshop.

I used to work for a printer and we kept all bitmap files as lossless compressed TIFF.

PDF is also just a container with basically the same bitmap compression options as TIFF. PDF was mostly designed as a Postscript vector container. It is more designed for for pages than individual images.

NeXT used Postscript as it's native display format and Mac OS X uses PDF in the same way.

+1

They are very versatile - scanning negatives of all sorts would be another option they offer.

For being able to do serious processing of the files I can recommend the TIFF option, JPG files are limited in this regard.

I have plenty of line art and type scans that are nothing at all like awful.

Thank you everyone for your replies, certainly in terms of the type of scanner required and the output file format, there is quite a bit to mull over before making any purchases.

Alot of the brochures I have are multi-paged ones and short of damaging them to pull them apart, a scanner of the type which feeds itself wouldn't seem to be the right choice. As some of the brochures are 60+ years old, some are quite delicate. I realise that I won't be doing a huge number of scans per day but I think that a flatbed scanner would be the best way to go with this idea.

As for the file format output, I was considering PDF (since brochures typically are a mixture of pictures and text) but I realise that linking the images together to form page 1-xx could be done by either naming the file in that matter, creating a subfolder or indeed creating a multi-page PDF document. Just like buying a camera lens, the choice doesn't seem to be straight forward and the scanning software would probably play a part in that too.

I see that new scanners now have a new USB Type C connection which looks similar but not quite the same as the recharge/transfer port on my phone and a68. That could cause an issue as well...

I think I need to do alot more research on this before I make any orders.

Thank you all once again.

It is not really opinion. Line art has hard edges that transform into infinite frequencies. The whole methodology of JPEG compression is to throw away high frequencies. The missing frequencies show up as ringing artifacts at hard edges and/or a loss of contrast.

JPEG is quite good for most natural photography.

Pictures are better than words. I just scanned a brochure page at 600DPI through Photoshop. Saved it as a TIFF and a high quality (PS level 10) JPEG.

Almost forgot, there's another aspect to this. JPEGs, although their quality is perfectly satisfactory for me, can be cumbersome for storing multipage documents. In those cases I like to create a PDF from the separate files. There you'll also have choices regarding resolution and compression schemes. Rather than tell you what my choices are, if you go that route I suggest you experiment with whatever PDF generating tools you might have and determine what satisfies you.

You can scan to multipage TIFF files, but PDF is far more widely used.

I too am partial to Epson scanners, but have had problems with support being dropped as the years roll on. As a result I use Vuescan software for scanning - it works with pretty much every scanner that exists - long after the scanner manufacturers stop providing drivers compatible with new OS updates.

I haven't had that issue.

I also have VueScan, but I only use it for Pacific Image dedicated film/slide scanners that come with extremely poor native software.

In this case you are oversampling the image, so, yes, JPEG is fine. The print is much lower resolution than the scan. No one needs to see half tones. An algorithm can convert those into smooth continuous shades.
