I have had this issue dating back to MS Word 2002, and know of several other
users fighting this same issue. I know the cause, but don't know of a
solution.
When printing a word that contains raster images (scans, Tiffs, BMPs and so
on) document to a PostScript printer (or a PDF) lines appear through some
images.
This happens in larger images (not sure of the size threshold here, but
suspect it is if over 1MB of information is in the raster image file). If the
image is greyscale the line is white, if the image is monochrome (Black and
white) the line is black.
The way MS Word is sending down the larger images is by breaking them into
multiple parts (which I think may only be about 16 kb each – the amount of
data is rather hard to determine). In the case of monochrome images these are
sent to the printer by MS Word with a black box that has a white knockout
overtop, the white knockout being slightly out of register (probably by less
than ¼ of a point - typical hairline), which is probably not an issue on low
resolution printers, however is visible at certain magnification in a PDF
document, and does print on higher resolution printers, such as those used in
the printing industry for output on printing presses.
Question is since this is a bug which the MS Word team does not seem to want
to address, how do I solve it?
