Today, more and amore documents are intended for web sit
distribution. Some of these documents will only be read on-screen and never
printed. Other readers will print your publication on a desktop ink-jet or
laser printer for later off line reading, however.
As Hardware and software costs continues to drop and new
technologies such as computing and wireless devices gain popularity, more and
more documents may never be printed in the traditional sense of the word. For
this reason documents will often need to be re-written for the changing times.
Potential problem Areas
As a general rule, always design for the worst possible
circumstances. If you design for “worst case” scenarios, not only will your
design survive the harshest of reading circumstances, but your design will be
even more successful in normal, everyday circumstances For
Remember that Online reading is harder than normal
On screen reading is far more difficult than reading a
printed document because of the differ way your readers eyes encounter your
message. Onscreen reading involves projected
light.
Your readers are, in effect, starting into the lens of a
slide projector. The individual letters making up your message are projected
onto the screen. This creates more foreground/background contrast or difference
in brightness levels than involved when reading a printed document. This added
contrast increases eye fatigue.
Reading a printed document involves reflected light . The
letters stand out against their background because the black letters and white
background absorb different amounts of light. As a result, the contrast range
is not as much, so there’s less eye fatigue.
Partial Page View
Another difference between print and onscreen reading involves
the limited amount of text visible at a time on scree. When reading a printed
document, readers can se the entire page, typically a vertical rectangle.
Without physical activity, scrolling though the page or
moving their head, they can quickly skim the document, going directly to point
of great interest and easily seeing how the individual paragraph they’re
reading relates to the page as a whole. They can easily read from the bottom of
one column to the top of the next.
Onscreen reading, however, typically reveals only a horizontal
rectangular view of a page. This makes it harder for visitors to get a “big
picture” view of what they’re reading. It also makes it difficult to return from
the bottom of the page to the top of the page. Readers of pint publications
encounter an entire page at a time.
