As a graphic designer working in print, it is important to understand and work to a set of fixed standards. This ensures that what the designer produces will actually be usable as a print item and also printable! For example in print, designing a simple business card has its own factors to watch for — this is also dependant on who you use to print your jobs. Some common issues to watch for would be if the job is of a standard size (and if the printer offers its own set of guidelines and sizes), if you decide to print in laser (which affects price as well as color), or offset, if you are using solid or process, how much bleed should you leave and if they have affordable metallics — the list could go on and on! Even with so many varied print issues, we feel comfortable ensconsed in our guidelines and the familiar set of difficulties.
