I'm having a problem when I print drawings with certain hatch patterns & diagonal lines. Some hatch patterns that have 45 degree lines & diagonal lines on the drawing print out with some of the pattern lines & individual lines darker than others. This seems to happen when I set up a print style using grayscale to "fade" the lines & patterns. I've tried changings the settings of dithering, grayscale & screening to no avail. no matter what combination of settings I try the result is the same; hatch pattern & diagonal lines that look "striped".

Can anyone help me fix this issue?
