Which theme layers and/or attribute items -

symbols and coloursd. Design map layout title,

4. Design Layout

• The following are key components of map design
• Title is required to define content
• Scale required, usually as scale bar (ratio can
  be problematic),
• Scale bar divisions by round logical numbers
• Boxes can be used to hold keys, sections or maps
  together
• Legend defines items not self-explanatory- must
  match exactly
• North arrow is often redundant if North is 'up'
  (but may be added)
• Latitude/longitude (or UTM) ticks (or location
  map)
• Data source and map designer ( metadata)

Encapsulated Postscript (EPS) Hewlett Packard
Graphics Language (HPGL) Adobe Acrobat Portable
Document Format (PDF) Colour - screen to print
differences - RGB versus CMYK

Colour - RGB (monitor) versus CMYK (printer)
RGB additive colours
CMYK subtractive colours

Printing devices
Monochrome cheaper, can be photocopied is
colour necessary Colour is required for much
output, due to complexity. From the 1990s, ink
jet Printers are the most common, but solid
colours can be too intense. Resolution Measured
in dots per inch (dpi).    300 dpi was a standard
in the 90s 600 and 1200 are now common, useful
for images and sharper text. Size Sheets up to
11 x 17" Ink jet or Laser Printers (100)Roll
gt 11 x 17" Ink jet (36 or 54 " drum). (10,000)
