The original Xerographic process of printing digital paper copies using black toner has come a very long way from the 1950’s. Mono digital print is used in increasing volume to produce short run documents for business, to overprinting pre-printed colour stock where volumes dictate that black text and personalisation printed on a colour format printed lithographically, works out more cost effective.
Just because you’re printing in a monochrome (black only), does not mean that you should create ‘bland’ or unbranded work. Most logos have a greyscale version, and if you design your print knowing it will be printed in greyscale – i.e. not one flat black, then the depth of image – particularly if using a quality silk paper stock will produce a very cost effective and impactful mail piece.
