No, LZW isn't lossy like JPEG and won't introduce any artifacts. Years ago,
most print professionals recommended against using LZW with TIFF's if you
were going to place the files into a page layout program (like Quark,
Pagemaker, etc.). Apparently the software couldn't extract the compressed
data. But I believe this problem has long since been fixed and most
printers now recommend it to save space.
