Are you sure? I don't think this is true. To test this theory, I took a 3.5 x 4.62 color 300 dpi image and saved it both as an EPS file and a TIFF file. I imported each image into InDesign, one at a time. Then I exported PDF's using the Press quality settings. Both PDF files were 1.12 MB. Just for kicks, I printed the EPS version to PostScript, then distilled using Press settings. I was not surprised with the results. The Distilled version was slightly smaller, 988KB. When I pre-flighted the PDF (Acro 6), the image indicated JPG compression.

In these cases I believe that any distiller settings for downsampling and compression are _NOT_ applied to the raster information inside the EPS. Lynn >Rich Sprague wrote: "2.
