Several people have commented that one really needs to scan at 4800dpi if you are going to try to plate stamps from digital images. I tend to rely on my microscope for plating, but I can't conveniently take photos through the microscope, and digital images are really a must for documenting and annotating my plating decisions. I currently use a Canon LIDE 220, and I scan at 2400dpi.

I am wondering if it is worth upgrading to a higher resolution photo scanner. Epson has several models that even tout 6400dpi optical resolution. I've looked at the ads for both these and other high-resolution photo scanners, but I'm unsure of how useful some of their features are for scanning stamps. For example, can film holders somehow be adapted to scan stamps?

I have the same Canon LiDE 220 and scan at 4800 dpi. I really don't see any difference when I do this.

Epson PerfectionŽ V600 Photo (6400 dpi optical resolution)- I have purchased and used a LOT of scanners over the years and I have several of these at home. One of them is over a decade old, has over 750,000 scans on it, and is still producing good scans.

My new Epson Workforce Pro WF-4830 goes up to 9600 dpi. The results do NOT blow my socks off, so I usually keep it much lower.

This has started out as a 9600 before dragging to this location...

I also use the Canon Lide 220 and love it. I scan stamps at 1200 dpi which is more than enough for plating.

Hi Casey,
The optical resolution of your scanner is 1200 dpi. Scanner manufacturer tout the scanner 'maximum resolution' but note that 'maximum resolution' is not the same as 'optical resolution'. 'Maximum resolution' is a software trick (basically using software to resize the scan), the 'optical resolution' is the highest hardware resolution the scanner can do without resorting to software resizing. When comparing scanners, it is best to stick to optical resolution.

The Epson PerfectionŽ V600 Photo has a 6400 dpi optical resolution but its 'maximum resolution' is 12,800 dpi.

I also use the Epson V600, now with the Silverfast software package (on my Mac). The change in results with Silverfast scanning software is such an improvement, I will soon be redoing all my stamp plating with it. Hoping to relaunch all of it by this Fall.

I concur with 1200 dpi. I have done all the larger dpi up to 9600, with no discernible improvement. Other image tweaking in photoshop and other adjustments makes a much greater improvement than increasing dpi.

Thanks Don. That reminds me of how cameras have a lens zoom, and digital zoom. Computer trickery.

I've owned Canon and Epson scanners over the years, and currently use an Epson V600. In my experience, Epson scanners are far superior for acquiring sharp images of stamps.

I use my scanner to plate almost every stamp I work with, and considering the image quality I get from Epson, 1200 DPI is sufficient for plating.

Thanks to everyone for your input and advice.

I've not been overly impressed with the difference between 1200dpi, 2400dpi or 4800dpi on the Canon Lide 220 either, but I know that image quality has a do with factors other than the optical resolution quoted in the specs of the scanner. I have also seen what I believe to be scanner artifacts introduced at the higher resolutions, and it's led me to question the real capabilities of the scanner. I let the scanner software convert the image data to a "high quality" jpg file, and I do not use the 48/16 bit color option. Both of these choices may be a mistake, but it's a compromise for convenience and to reduce scanning time.

The Epson Perfection is touted as producing very accurate scans. The 600 model is moderately priced, and I may switch to it. I'll add the Silverfast software too, if the price isn't ridiculous.

Interesting, nice to hear a positive.
when researching scanners, Silverfast had many non positive issues.
(May have been Microsoft Windows issues)

I recommend VueScan Professional, 'try before you buy' here https://www.hamrick.com/

- supports saving calibration with 3rd party targets
- support saving scanning configurations
- has its own scanner drivers which produce different results than the app using the scan manufacturer driver
- supports one click scans (real time saver when doing multiple scans)
- supports custom file naming patterns (another great time saver)
- supports all the silly post image processing 'features' which many folks seem to like to use to over-saturate and 'enhance' their images
