Hi
the problem you ave has nothing to do with pagemaker, photoshop of your image. It has everything to do with your monitor and the diferences in displaying colors in photoshop and pagemaker.
Photoshop being a programm that needs an accurate color management has a better way of displaying colors on your monitor. Pagemaker being a layout programm has not asmuch possibilities and doesn't need them because your image has all the qualities you gave it in photoshop and they are still in the image. So viewing the file in its optimum view is not always necessary.
But you can arrange the quality of your view in the preferences. Set the quality of placed images to hig and you will get a better view, but this also slows down the rebuilding of your screen and is only used when everything is put in place and you wan't to view the file in it's optimum quality, then quickly turn itback to normalin your preferences
