PCB layout

There is a PCB has 3 normal ICs, so it need to be accurate in size. I used Adobe Photoshop software to measure size and it is accurate in photoshop. Then I saved it as a JPG picture but the size changed from actual 7.5cm to printed size 6.7cm only!
I tried with different resolution but keeps the same.
Where is the problem? What may be the reason? Are there any setting on PC or printer to print accurate size?
