Digital printing tends to be used for more complex graphic designs and in cases where the quantity of printed materials is too low to make screen printing cost effective. The quality of digital and screen printing is comparable. The high quality of print is visible not only in coloured print, but also in the case of black and white text. Digital printing is usually used for short production series. A useful feature of this method is the ability to personalise prints. Digital printing is also resistant to adverse weather conditions. This makes it possible for digitally-printed materials to be used as durable outdoor signage.
