In the Driver, under the Raster Type setting, change “Basic” to “Stamp” in the drop-down menu. This will allow you to access two additional stamp options - shoulders and widening.
Shoulders: The Shoulders setting in the print driver adjusts the angle of the sides of the characters on your stamp. A higher shoulder number provides a wider angle and more support for the characters. The following drawing shows a side view of a character with the Shoulders set to 10, 25 and 50. Many users feel the default setting of 25 is ideal.
Widening: The Widening setting in the print driver adjusts the character weight. A higher Widening number provides a bolder character. The following drawing shows the difference in characters when their Widening set to 1 or 6. Many users feel the default setting of 1 is ideal.
