1. Using GRAPHICS
Bristol Community College CIS 13 Business Creativity Sources: Conference for Desktop Publisher and Others

2. What is Clip Art? Using GRAPHICS
Originally, artwork that was purchased and clipped out before using.
Clip art…
Can be used to add interest
Can create focal points
Can enhance a publication
Can be modified
Can be overused
Cannot be used without permission
unless it’s royalty-free

3. Where do we find Clip Art?
Using GRAPHICS
Where do we find Clip Art?
Collections on CD
Web sites
Original art

4. GRAPHICS Two basic forms of Images
Using GRAPHICS
GRAPHICS Two basic forms of Images
Raster
Dots
Vector
Drawn by a mathematical formula

5. GRAPHICS Raster Images
Using GRAPHICS
GRAPHICS Raster Images
Bitmapped
Stored in grids like graph paper
Typical formats:
jpeg, tiff, gif, and bmp files

6. GRAPHICS Do Not Enlarge Raster Images
Using GRAPHICS
GRAPHICS Do Not Enlarge Raster Images
It only makes the dots bigger
it doesn’t create more dots
It creates “jaggies,”
or jagged edges

7. Two Types of Raster Art: Line Art + Continuous Tone
Using GRAPHICS
Two Types of Raster Art: Line Art + Continuous Tone
Line Art
No gradation of tones
Every pixel is black or white
Example: Pen and ink drawing
To appear smooth, use high density of dots
1200 pixels per inch is recommended
PostScript language supports 600 ppi (pixels per inch)
or dpi (dots per inch)
Scan and print at 600 dpi to achieve effect

8. Two Types of Raster Art: Line Art + Continuous Tone
Using GRAPHICS
Two Types of Raster Art: Line Art + Continuous Tone
Continuous Tone
Many shades and levels
Examples: Photographs and paintings
Screening creates impression of variable tone
Actually, density of dots create the illusion
Types:
Grayscale (black, white, gray)
Duotone (two colors)
Color (cyan, yellow, magenta, and black)

9. GRAPHICS Vector Using GRAPHICS
Art is created by curves using a mathematic formula
Created in a drawing and painting program like Illustrator, Freehand, or Corel Draw
Save as an EPS (Encapsulated PostScript) file
Can be enlarged without “jaggies”

10. GRAPHICS Vector to Raster and Back
Using GRAPHICS
GRAPHICS Vector to Raster and Back
Open a vector file in Quark, Illustrator or Powerpoint and it stays a vector file
Open a vector file in Photoshop, it becomes bitmapped or rasterized.

11. GRAPHICS Photos Photos are bitmapped/raster images
Using GRAPHICS
GRAPHICS Photos
Photos are bitmapped/raster images
Scan them at the finished size
The higher the resolution, the better the quality, but the output device determines the dpi
Monitor = 72 dpi
Laser printer = dpi
Image setter = dpi

12. GRAPHICS Scanning Tips
Using GRAPHICS
GRAPHICS Scanning Tips
Type of Graphic:
On Screen/Web
Print
Enlarging Photo
Scan at:
dpi
dpi
Maximum
File Format:
JPEG
TIFF
Remember: Higher resolution = larger files
4”x6” b&w 8 bits 300 dpi 2.2. MB
4”x6” color 24 bit 73 dpi 360K
4”x6” color 24 bit 300 dpi 6.5 MB
8”x10” color 24 bit 600 dpi 84.4 MB

13. GRAPHICS More Scanning Tips
Using GRAPHICS
GRAPHICS More Scanning Tips
Scan at the level of the image
If an image was created at 300 dpi, scan it at
300 dpi
Scanning a 300 dpi at 600 dpi pulls forward imperfections
Enlarging Raster Images Scanning Formula:
(final width/width of original image) x final ppi = scan ppi
example: (8 inches/4 inches) x 300 ppi = 600 ppi

14. GRAPHICS Saving Graphics for WEB
Using GRAPHICS
GRAPHICS Saving Graphics for WEB
GIF (Graphics Interchange Format)
Good for sharp lines, but large files
JPEG (Joint Photographic Exports Group)
Excellent for reducing large images into small files
PNG (Portable Network Graphics)
Free alternative to GIF, becoming more widely used
Avoid BMP (art, wmp and pict)

15. GRAPHICS Saving Graphics for Print
Using GRAPHICS
GRAPHICS Saving Graphics for Print
TIFF (Tagged Image File Format)
Best choice and most common
Works on both Mac and PC
Can be large files
Industry standard
EPS (Encapsulated Post Script)
Includes the PostScript instructions
Avoid if saving publication as an EPS document
