This is a known issue (at least, I am familiar with it). I assume you
are using jai_imageio.jar. The behavior is due to a bug in JAI (see
http://www.java.net/node/702556) that causes the images to be treated as
RGB + Alpha. The reason you do not see the problem when producing PDF is
due to the fact that FOP uses a native image loader if the output is PDF
(i.e., it does not use JAI).
I was not aware of the issue you point out with RGB TIFFs and deflate
compression. Can you provide example images with flate and LZW compression?

Hi to all, I am facing problems using images with FOP with afp renderer.
Specifically, a JPEG or TIFF with CMYK colorspace ends in wrong
colors, even if
the cmyk="true" attribute is added to the configuration file.
When using a TIFF (RGB) with "deflate" compression type, the picture
is mostly black, using LZW compression is OK.
Tested with 1.1 and the nightly build of FOP.
Enclosed here the configuration file:
<?xml version="1.0"?>
<fop version="1.0">
<base>.</base>
<source-resolution>72</source-resolution>
<target-resolution>72</target-resolution>
<default-page-settings height="11in" width="8.26in"/>
<renderers>
<renderer mime="application/x-afp">
<renderer-resolution>240</renderer-resolution>
<images mode="color" cmyk="true" />
</renderer>
</renderers>
</fop>
Thanks
