Hi, Matt,
Check out these posts -- it appears that you may not actually be doing
anything wrong after all:

Hi All,
I'm trying to print a NSGradient or CTGradient that comprises two
colors with alpha.
It draws fine on screen, and draws fine in the print panel preview,
but when I create a PDF or print it, the alpha is not respected at
all.
Here is my drawing code:
- (void)drawRect:(NSRect)rect {
// Drawing code here.
[[NSColor blueColor] set];
NSRectFill(rect);
NSGradient *gradient = [[NSGradient alloc] initWithStartingColor:
[NSColor clearColor] endingColor:[NSColor colorWithCalibratedWhite:
1.0 alpha:0.5]];
[gradient drawInRect:NSInsetRect([self bounds], 5, 5) angle:90.0];
[gradient release];
}
You can check out how it looks on screen and in print here: http://skitch.com/mattski/m78t/window
Any help would be greatly appreciated.
Thanks,
