Map Production
• Computer Screens (CRTs, Monitor):– Emit light in a grid– 75-120 dpi– Red, Green, Blue: Millions of colors– Good for contone
• Printers:– Place ink on paper– Cyan, Yellow, Magenta, Black (CYMK)– 300 to 2000 dpi– Good for spot color

Color Printer Process
• Get the layout right
• Test the margins on a black and white printer
• Test the color print
• Adjust the colors until they look good
• Show it to others including target audience
• Cut off a white border if desired

Offset Press
• Professional grade
• Large numbers of copies– $500 for 500 copies– Cheaper for additional copies
• Each color on a separate “plate”
• Can mix special colors
• Almost all magazines and books are printed on offset press

Pre-Press Process
1. Talk to the printer!
2. Follow color printer process
3. Take the file and the color print to the process printer
4. Process printer creates “photo ready art”
5. May do a test run
6. Approve final output

Paper
• Paper is graded by “hardness”– Newspaper– Office paper– “Hard” paper (Hammermill)– Glossy paper
• Colored paper– Dark colors rarely work with computer
printers– Use white paper and print the background
