Digital printing is a method of printing using digital techniques in which the data and images are printed directly from a computer onto the substrate, including those developed for computer printers such as inkjet or laser printers. The process differs from lithography, flexography, gravure, and letterpress printing in several ways:
Every print can be different, because printing plates are not required, as in traditional litho or screen print methods.
There is less waste chemical and paper, because there is no need to bring the image "up to colour" and check for registration or position.
The ink or toner does not permeate the substrate, as do conventional inks, but forms a thin layer on the surface and may in some systems be additionally adhered to the substrate by using a fuser fluid with heat process (toner) or UV curing process (ink).
Because there is less initial setup, it is useful for rapid prototyping, and cost effective for small to medium print runs. With virtually no setup, individual designs can be printed even if just for one item. As the colours used are CMYK, the ability to match any image or colour is possible and with the range of machinery on the market today, any size is achievable on a wide range of substrates. Modern digital today can be used for direct printing of Posters, Banners, Exhibition graphics, POS, External/internal graphics and Vinyl’s to name just a few.
