In-Depth Information
For example, you could not render ultra-bold text next to ultra-light on screen, where-
as you could in print. Also, the user does not have to be contained by a page; in the
digital realm they can scroll around information, or even change its orientation from
portrait to landscape.
Navigation in print is as simple as flipping a page. The user can scan through quickly
at full size and decide what to read based on what grabs their attention. On screen
this becomes more challenging. Navigational elements have to be clear and obvious,
so there is no misunderstanding. A smaller screen can mean smaller text and narrow-
er columns, which can prove difficult to read. Readability tests suggest that columns
should have around seven to ten words per line, or 50 to 70 characters. This is the
reason many websites use a single column of text that has scroll bars.
When designing with print, fewer clues have to be given as to how to navigate the
information. Although the principle on screen is similar, these clues have to be more
specific and visually stronger.
Designing for different digital platforms
When designing screen-based information, there are several digital platforms that
may have to be taken into account. These range from traditional screen delivery plat-
forms such as websites or television to mobile technology such as tablets and smart-
phones. All are of varying sizes and resolutions and will have particular limitations
that may require amendments during the design process.
All digital technology uses a screen to display the information. In the same way that
computer monitors are calibrated for optimal viewing, the display screens on mobile
phones and other digital devices are calibrated for brightness, contrast, colour depth
and resolution. This can cause problems when rendering typography, as it will not
appear as crisp as it would in print, and also with colour, as different screens are cal-
ibrated in different ways.
Navigation can also be challenging, as the user needs to be guided as to where and
how to follow the path between pages or screens. This section highlights some of the
differences and considerations needed when designing for these platforms.
