The connections on a PCB should be identical to its corresponding circuit diagram, but while the circuit diagram is arranged to be readable, the PCB layout is arranged to be functional, so there is rarely any visible correlation.

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?
