CSE3325: Typography

In the previous lecture:

• DHTML is a collection of technologies for making web pages dynamic.
• Typically DHTML involves a scripting language and a Document Object model on which it acts.
• Cascading Style Sheets may be used to specify the layout of a page and these style descriptions may be acted upon by a scripting language.

In this lecture:

• What are the different kinds of type?
  
  
• How may type be used effectively in multimedia production?

...the art of printing, particularly those branches of it concerned with the design, setting, and arrangement of type.

Printing

...the making of impressed copies from the inked surface either of an engraved block or metal plate, of a lithograph, or of movable type...

Technology has changed, but the need to master type remains!

ATTENTION!

Definitions, definitions...

Face / typeface / font: a set of characters
(letters, punctuation marks, numbers and assorted textual symbols such as @#$%)

Family: a group of typefaces sharing common features.

The two most common families of type:

The serifs are the little marks at the ends of the sweep of the lefthand S.
'Sans' is French for without, so it's no surprise that a Sans Serif font is a font without serifs!

Some Serif typefaces...

Serif fonts are frequently

• elegant,

• easy to read,

• suitable for body text (look at the text in most novels).

Serif fonts have a formal quality about them.

• Oldstyle typefaces have serif's angled or curved in the manner of a pen and ink scribe's strokes. These fonts can look very elegant whilst maintaining readability.
  
  
  

• Modern typefaces have serifs which have been flattened into industrial / machine like regularity.
  
  
  
  

• Slab Serif fonts have chunky serifs. When slab serif's are combined with heavy, bold strokes the font can be very 'in your face'. Compare the weight of Slab with Century and Bodoni! Which draws your eye the most?
  
  
  

Serif fonts are:

• rounded and smooth,
  
  
• frequently used for headers,
  
  
• legible in short bursts of text,
  
  
• less readable than serif fonts in solid blocks of text.

Decorative typefaces like these

may be used to convey a mood or set a look and feel...

but should be used sparingly as they are hard to read in large quantities!

Script fonts emulate hand writing. The characters follow into one another.

works poorly in body text but, like decorative fonts, may work well in short sections, headers or on dance party & birthday invitations!

Monospaced faces such as Courier allow the same amount of horizontal space for each letter.

For example, count the x's below (Courier on the left, Helvetica on the right)

Monospaced characters line up in columns which is vital in many circumstances!

You can specify a monospaced font using a <tt> tag that will give you this effect </tt>.

You can specify a monospaced font using a tag that will give you this effect.

A better way to specify typefaces is to use Cascading Style Sheets (CSS).

Type Form

Roman text - standard / medium weight font.

Bold text - provides emphasis, adds weight to a page by thickening the character strokes.

Light text - subtle and gentle characters produced with slender strokes.

Type Width

Condensed text - (compressed) less character width than Roman text of this style.

Expanded text - (extended) more character width than Roman text of this style.

(It is actually the letterforms which are altered in these types, not the spacing between letters.)

Italic text - slants fluidly to the right in the manner of handwriting.

Oblique text - slants rigidly to the right not in the manner of handwriting.

(The character's inclination might be the same, but the Sans Serif font looks regimental whilst the Serif font flows like handwriting)

Is measured in points

There are 72 points to an inch (that's 2.54 cm)

Size of text should indicate its importance relative to other page elements.

Headings should be large.

Footnotes should be small.

And body text should be just so! (Usually around 12pt)

Be consistent with all your font decisions, including size!

may

Be aware that horizontal text appears more stable and is more easily read.

Coloured Text

Small highlights of coloured text can be used to great effect.

But avoid making your pages difficult to read by inappropriate use of colour.

Leading - distance between text lines.

Kerning - space adjustment between particular letters of a font which otherwise appear too distant or too close to one another.

(E.g. Note the strange gaps between uppercase 'T' and lowercase 'o', uppercase 'Y' and lower case 'o', uppercase 'I' and lowercase 'n'. Also note the irregular gaps between the lowercase 'w' and the 'o' and 'a' on either side...)

Spacing - horizontal space between all letters of a font.

Anti-aliasing is of benefit to smooth the jaggies around large characters...

...but it can make small characters blurry and illegible...

So, how do you do this in a web page?

• In the past there was the very limited and problematic HTML <font> tag.
  
• Now fonts are specified using Cascading Style Sheets.
  
• Insert bitmap images of text like in these lecture notes. (You must specify a helpful alt attribute for your textual images.)
  
• Use colour especially wisely for text.

   

This will depend on the family from which they spring, their orientation, position, relative size and weight and a host of other characteristics, all of which need to be understood to enable the message contributed by the fonts to meet the goals of the production within which they appear.
