Soft Proofing represents the ability to check how your photo will appear after is printed. You can use the information provided by soft proof to prevent colour distortion by adjusting your picture according to your preferences before you print it.
Calibrate your monitor
UA very important step is to use a calibrated monitor while you adjust your image. You can calibrate your monitor by using a special tool like Colorimeter.
ICC colour profiles
Setting up the soft proofing requires ICC colour profiles that will help you to match the exact colours of your image. Proper calibration of the ICC profile is essential for digital photo printing in order to maintain true image colours.
With a calibrated monitor and a soft proofed picture you’ll surely get the desired result.
