I see. Sounds like we might want to use non-integral widths even for screen fonts. Is incompatibility with AppKit serious? I'm also curious if subpixel positioning won't break web compatibility. If these concerns are not so important, I'd like WebKit uses non-integral widths. If I understand correctly, I cannot see the code from outside Apple, right? If so, can I request the change?

Thanks for the info. I confirmed we can get the same result between screen and printing with Lucida Grande. Please let me know if there are some other workarounds for this.

Thanks for your comments!
