washed out blacks in b&w trade book images

How to get neutral greys and strong blacks in the b&w trade book, 6 × 9 inch? I prepped the images in Photoshop and sent in as desaturated jpegs.
My first printing from Blurb came back with a color caste to the cover and the inner pages had a greenish caste but the blacks were adequately dark.
To achieve a neutral b&w image, customer support suggested I send the cover image in as an srgb saved as a .PNG file, and sized to 300 dpi as the full sized cover.
The resulting book I received had a somewhat more neutral cover but totally washed out blacks on all inside pages, only weak greys.
