MATLAB: I need help with “imread”

digital image processingimreadMATLAB

I have a scanned document image https://www.dropbox.com/s/jy2wuvmqcj7b1eu/sf3r_0006.jpg. And when I read it into matlab using "imread" function most of the details are lost https://www.dropbox.com/s/2s75833ayfsie74/img.jpg. This happens to all my scanned pictures too. The pictures were scanned at 300dpi. Please any suggestions on how I can read the images without loosing the details would help. I'm using matlab 2011Ra.

Please explain how you get from "read into Matlab using "imread" to posted jpg. I'm convinced, that the picture is read correctly and only the display on the screen looks strange, because it is downsampled from 300 dpi to 72 or 96 dpi. If the "scanned" image is a black&white scan, such optical effects are expected.
