Getting started : Scanning your Stamps

In order to start using the Stamp Analyser, you will need  images of the stamps that you want to analyse.

There are three ways of obtaining the images.

  1. Scan your stamps; simple and by far the best method, see below for the procedure;
  2. Photograph your stamps; tricky but doable, click here  for the procedure;
  3. Obtain the stamp images from any website, click here for the procedure;   

Scan your stamps

You can use any type of scanner. In fact, most printers that double up as scanners produce good quality scans that are fine for our purposes. You will need to adjust only one parameter on the scanner; and that is the resolution or the DPI at which the stamp will be scanned. For optimal results, we recommend that you set the DPI to 300 and place the stamp on a “clean” black background when scanning.

If required, you can enhance the scanned image  by adjusting the Exposure, Contrast,  Saturation etc.  However, you should not resize it, as pixels will be lost if you make it smaller and interpolated pixels will be added if you make it larger. Resizing invalidates the original DPI and hence the perforation and frame dimension calculations.

To transfer the scanned images to your device you will need to install the software that the scanner manufacturer provides. For mobile devices, this will be an application that can be down loaded from the Apple App store. Please refer to the scanner documentation for the procedure to install their software  and the procedure to transfer the images to your device.

If you want to transfer images to your mobile device from older scanners that do not have wireless capabilities, you will need to transfer the scanned images to a Mac or PC first, and then use an application, such as iTunes or iCloud, to transfer the images to your mobile device.

Once the image has been transferred to the your device you may need to  need to crop it, leaving a small border around the stamp.  The procedure for cropping will depend on the  Stamp Analyser version  #  and the device that the Stamp Analyser is running on, as follows:
