Don't convert to an output (printer) profile. Instead leave images in their

properly reads and converts from the Matrix profile to the printer profile.
OTW color manage your images earlier in Photoshop by converting to your
output profile and DON'T embed the profile in the PDF doc. Ensure your PDF
is not converted or color managed downstream.
On the whole rather bad advice.
ID152 uses intents symmetrically, just like PS50 and PS55.
a. Therefore, you should place tagged RGB or Lab for repurposing, but
NEVER in a RIP. Three channel spaces map to the CRD in the printer
(using any of a set of different parameters). You have no control
over the intent this way, barring RIPs whose programming you know
very well indeed. And that is rare.
For three channel PDF workflows, place iQueue in front of the RIP,
and make sure the RIP receives cross-rendered (: pre-proofed)
deviceCMYK which in PSL1 - PSL2 - PSL3 is output by the numbers.
b. If you intend to proof print and soft proof out of ID152, place
only tagged CMYK, use a combination of the input filters (assign
default assumed source and intent) and the Image Color Settings
dialog (apply embedded but rotate intent as required), convert
document colors to CMYK Separations profile, and you can soft proof
and proof print just fine, no need of a color server.
For those who wish, there is as far as I recall a 30 day free working
demo of iQueue on the site.
For those who wish, there is I think a 60 day free trial version of
ID152 on the Adobe site.
Some of you may still prefer XPress for its speed, and I'll grant
that any old day. But I love type and color, and I get neither in
XPress. Not even decent spellchucking (: 'col-ors' my foot -:)).
