Scanning of stamps

Personal use

The most important thing is to start scanning in high resolution, I have good experience with 1200 dpi. Most scanners have a standard 200 or 300 dpi, but it is in my opinion too little for scanning of stamps. The high resolution allows admittedly very large files, but most programs can handle it. Try with 1200 dpi.

When you make the first scan of a stamp, it is important to store it in an original format as TIFF as this format stores all the information about the scan. If you use JPG in stead you will loss some of the information and you will loss information each time it is compressed.

A two-color stamp fills approx. 3 mb scanned at 1200 dpi and saved in TIFF format - it gives a super quality if the brand adapted to the size of your screen.

Use on the homepage

Scan your stamp at 1200 dpi and save it in JPEG format. The homepage can not display image in TIFF format.

If you can then adjust the image to a width of 475 pixels or 950 pixels - that's the size I use on the Web (four-block is 950 pixels wide). The image is compressed so it takes up approx. 200kb, but they can actually be compressed more without losing much when showing on the homepage.

Remember to name your scans with something meaningful and avoid æ ø å / : , . \ in the filename.

E.g.: 25ore-t10-p98-ofxx.jpg is the filename for a 25 øre stamp, print 10, position 98 and a unknown oval flaw. 

E.g.: 25ore-txx-PXX-of11.jpg, is the filename for a 25 øre stamp, print unknown, position unknown and with oval flaw 11.

Hope that makes sense.
