Hi Guillaume,
I reordered your reply to bottom posting. Thought, this is common in web 
forums, resp. mailing lists.

The images are very large in disk space. They can be downloaded from:
- image as it should look like, scanned with 75dpi
https://dl.dropboxusercontent.com/u/69356214/nypd-75dpi.png
- image scanned with 1200dpi
https://dl.dropboxusercontent.com/u/69356214/nypd-1200dpi-onA5.png

regards,
Chris.
