placed psd files in ill. now have...

[lbeier05]

I have just taken a bunch of images I have edited in photoshop, removed their backgrounds and placed them on a new transparent background. I have placed them all in a illustrator file as I want them and added a rectangle to the background and filled in the color with a neural blue. (trying to add a background color other than white). I saved the file as a pdf so other computers can print the file and when I print I am getting the transparent background from the photoshop file showing up in the document as darker than the rest of the document.
Any suggestions?

If all the images started in Photoshop, why would you need to place them into Illustrator. Why not add the blue rectangle in Photoshop?
