Hi,
I’m building a website for a local carpet company.
I have obviously got to include their logo on their site and have had to scan in from a compliment slip.
The quality of the printing on the compliment slip results in a pretty poor scan – which can be found here:

The scan has a very blocky appearence (when highly magnified) and the edges are all over the place. There are further details of the process I have used thus far at the web address above – but you will see that they have not worked :o(
If anyone could offer some advice on how to get a nice crisp black and white version from this scan it would be very much apprecited.
As others have mentioned, your best results will come from using Illustrator and tracing it. You’ll get the smoothest edges and infinitely scalable art.
If you want to do it in Photoshop, you can try this:
Scan at the higest resolution your machine can handle.
Use levels or curves to increase the contrast such that the letters are as dark as possible and the background as light as possible. There will still be speckles. Don’t worry about them.
Apply a mild gaussian blur (this will fill in the speckles and soften the edges). I can’t give you a number because this will depend on the image’s resolution but I’m guessing somewhere in the 2-6 range for a very high res. image.
Convert the image to greyscale.
Use levels to sharpen the image by dragging the sliders as needed to expand the black and white areas and eliminate the grey). This is a fairly common way to clean up line art which I learned way back when Kai’s Power Tools was in version 2 and one could access Kai’s Power Tips.
Apply the unsharp mask.
You should be able to get fairly smooth results this way although it’ll be nothing like drawing a vector version.
I tested this method on the low res. version on your site and this is the result I got:
