DWG to PDF Hatch Problem

[SeaRR85]

I'm using AutoCAD LT 2007. I'm using solid hatching in my DWG drawing. When I convert from DWG to PDF, the hatching on the PDF seems to have some mysterious gray lines running through it. Please help! I don't like gray lines!

Try changing the rotation of the soild hatch... (I just made that up so don't know if it'll work)
but also try printing to the PDF at a higher resolution.
