The document contains a larger number of images. As these are results from scientific computations, they contain a large number of details. This allows the user to zoom deep into the image when viewing the document on screen. However, in the printed version it is obviously not possible to resolve so many details. The publisher claims this may result in unexpected appearance of the images during the printing process. I am not sure about the technical reasons and differences of book printing to regular home printers, but he asked me to provide bitmap based graphics instead.
Too fine detail will be lost - that is obvious. The interesting part is how. If a single pixel contains some white and some black due to fine detail - what should happen? Black pixel? White? Gray pixel? (Gray might not be possible). And when many such pixels make up a region - will the whole region be white/black? Or a dithering pattern? Aliasing effects?
Their press might do this reduction a bit different than your home printer, hence the warning about surprises. They are publishers, not experts in your field. So they might not understand your computed images. So they cannot tell a "bad" conversion form a "good" one. which is why they tell you to make bitmaps in the native resolution of their imager. They can then print exactly what they get, no surprises. You get full control of the conversion process, and can review each image. If some are bad, you can use different parameters or different software to process them. You don't want the first edition to print with some griveous conversion fault - and they don't want that either.
