Hi StampCollector
I used a microscope to photograph the difference so the detailing can be easily seen. You can use a strong magnifying glass to identify what you have by using the images provided for identification, Also a little piece of info about this stamp from a Stanley Gibbons catalogue on Australian stamps.
Digital
Stamps printed digitally at six different sites, under magnification, in this case a microscope, the Australian flag, Olympic rings and inscription has blurred outlines (rough).
Lithography
Stamps printed in lithography by SNP Ausprint, the Australian flag, Olympic rings and inscriptions show sharp and clear outlines.

Thanks for the info.
I don't have a microscope but my 20X MG should do the trick.

May I ask about your microscope and what power you are using? From the microscope to the computer how or what is needed? I'm asking because I'm looking for myself.

It's perfect to enlarge varieties, errors and anything else involving stamps.

It's not something I've ever considered buying. I find scanning at 2400dpi shows me what I need, and I imagine it takes as long as getting a stamp ready for the microscope. Cheaper too!

I have a Celestron USB microscope and it is easy to set up but I am not doing close up work that often. It can be tethered or standalone and has a built in display.

The Celestron USB microscope is very similar to mine, these microscopes are very handy for stamps.

Hi Dave
I tried scanning at 2400dpi but it was too slow, was going to take 30 minutes, may be the type of scanner I have.

I use a Canon Lide 400. The top scan here is 2400dpi, and took 15 seconds. The second is 1200dpi and took 6 seconds.

I can see my scanner is slow when it comes to using 1200dpi and 2400dpi, though I use 600dpi for the images and for detail the microscope is used. Although it is obvious you do get a large image that isn't distorted, I find that the microscope can give far greater detail to even the smallest imperfection.

Can someone tell me how to tell apart the FujiXEROX printed stamps from the SNP Ausprint printed.
