All images you see on your screen now has 72 DPI (pixels per inch). This resolution is ideal for displaying an image on screen, but not for printing.
To print your documents on the press ( offset or digital ), the ideal resolution for photos is 300 DPI (pixels per inch) at final size. This resolution will give you the best possible quality of your images. By cons, if the resolution is 225 dpi or higher, the quality of the printed product will not be affected.
If, cons, you decide to print a picture with a resolution below 225-PPP, you lose quality (the picture becomes more blurred).
If you have very little resolution, we may even see the impression on the square pixel color.
To be sure your images have good resolution when printed, here's how to calculate it:
Screen ruling PPP = X 2 (P ixelles per inch)
Ex: 150 LPI (lines per inch) X 2 = 300 PPP
In The Modern 'Printer , we use a high resolution screen frequency to 250 LPI. For cons, the technology allows us to maximize image resolution, so print your photo at 300 DPI at its best quality.
