Scanning Stamps To Make Poster

Hello
I've just joined this group, I've inherited some of my great grandfather and fathers stamps and also been reunited with my childhood collction after many years.
I want to scan a few individual stamps to make posters, as big as possible.
What would people recommend for this?
Many thanks

A high-quality scan and a local printing shop?

The bigger the poster the higher resolution scan you need.

Hi thanks for the replies

Can anyone offer advice on the best way to do the high res scan please for a large print?

Thanks
Sl

The chances that some reader here happens to be a print shop owner seems small...
1. To scan stamps, you need a flatbed scanner (and a computer, obviously). 50 quids probably gets you a Canon Lide 300 or so.
Don't even think of your cell phone camera, the results will be disappointing.
2. Next you find a print shop in the town you live.
3. Ask them what it takes to make posters out of your scans.
4. Depending on their willingness:
a) They just tell you to give them the scans (you need a USB stick with the data on it) and how you want them organised.
b) You need a program that can arrange your scans into a (really big) file of the type the print shop wants.

I also recommend you save the file in the TIFF format. It is uncompressed and will preserve the scanned image quality.

That seems to be a common misconception about jpeg that lingers in people's minds. Nothing gets lost with lossless jpg compression.
I just took a screenshot and saved it as
TIFF: 6.59 Mbyte
JPG (lossless): 751 kB
The images are identical if I look at them at 500% magnification - as expected by the "lossless" jpg setting. So jpg saves you a lot of space. Not that this would matter anymore with TBytes of disc space nowadays - it did matter greatly when harddisks were well under 100MBytes in storage size.

With stamps (that are often single color), space savings are even bigger.

But the print shop will call the shots..

If you don't have a scanner, the shop should be able to do that for you, with better equipment.

Talk to a printer about the results you want and work backwards from their advice.
