I have banner file size of 1600x280cm in Illustrator cs3 have 50% (320x56cm) and i am opening it in Photoshop cs3. the problem is that software doesn't open in actual size (1600x280cm) with 72dpi resolution when i do this resolution it size convert into smaller. but with 50dpi resolution it is ok and open the file but we need a 72dpi resolution.

Thanks
