Linetype Scale not compatible between two drawings

I'm using AutoCAD LT 2007 and have a problem with linetype between two drawings. I have a standard key which I use on a number of drawings, problem is when I copy from my original file (in model space) to paper space on another drawing the linetype isn't viewed the same.

I've set LTSCALE to 1. PSLTSCALE to 0, Global scale factor to 1 in both files but still no joy. Any ideas?

Thanks in advance.
