![]() With the naked eye we cannot normally perceive this, but the macro photography below shows how very few ink dots are needed for each pixel. In fact, the printer usually needs a higher number of dots to represent a single colored pixel, because of the way the colors are mixed. But this doesn’t mean that the printer is going to “draw” 300 points on the paper for every inch. Usually, for a quality print, we need about 300 DPI, meaning that an image the size of an A4 paper should count 2480x3507 pixels. We can imagine DPI as the number of pixels which would be needed for one inch (2.54 cm) of printed paper. As the pixel is the smallest unit of a digital image, it doesn’t really exist outside digital screens! Naturally, when printing an image, we can measure its size, but, to determine it, the printer makes use of a ratio which is called dots per inch, or simply DPI. The only reasonable answer for this question is “It depends”. ![]()
