2. Desktop PublishingDesktop Publishing
 the use of computer-based software
and equipment to produce publication
materials (includes use of graphics and
text)
 DTP features equipment small enough
to fit on a desk (hence the name), yet
capable of producing very high
quality, inexpensive documents

3. Desktop PublishingDesktop Publishing continuedcontinued
 Desktop publishers “import” text—
often Word files (.doc or .docx) from
writers to layout publications.
 At the high school level, usually
programs such as Microsoft Publisher
(.pub), or Adobe Indesign (.indd) are
often used.

5. Graphics:Graphics:
 Two main types of graphics are referred to as
Raster or Vector.
 Both raster and vector graphics have specific
applications within the “design industry.”
 Many desktop publishers/graphic designers,
etc. will simultaneously combine both
graphics within their work, i.e., adjust lines
within a vector drawing and touch-up or fill
those line drawings within a raster
program/drawing.

6. Graphics:Graphics:
Raster Graphic Vs. Vector Graphic
When “zoomed” in, notice the difference

7. Graphics:Graphics: Raster GraphicsRaster Graphics
 Graphics are produced using a grid of
small squares known as pixels. Each pixel
is assigned a specific colour value and
location.
 When editing a raster graphics (ex. Digital
photo), you are actually editing pixels
rather than objects or shapes (Photoshop,
MS Paint, Corel Photo-Paint).
 Pixels can be seen by zooming in on a
digital image (tiny squares).

8. Graphics:Graphics: Raster GraphicsRaster Graphics
 Pixel dimensions for a graphic (photo)
will vary in size. This will depend on
scanner settings and/or digital camera
type/quality.
 Typical 5 X 7 inch image at scanned at 300 dpi
would have a dimension of 1500 X 2100
 Typical 12 – mega pixel camera is capable of
3000 X 4000 pixel photos
 When searching for photos/graphics on Google
use the option of Large Images Only to focus
your search on quality images (see next slide)

11. Graphics: Raster GraphicsGraphics: Raster Graphics
 Raster graphics are generally larger
files than vector images.
 Images lose quality (become
“pixelated”) if enlarged more than
20% of the original size.

12. Graphics:Graphics: Vector GraphicsVector Graphics
 Drawing programs such as CorelDraw
and Adobe Illustrator produce vector
graphics.
 These types of graphics are made of
lines and curves defined by
mathematical objects called vectors
(geometric characteristics).

13. Graphics: Vector GraphicsGraphics: Vector Graphics
 A vector graphic can be moved or
resized without losing quality and file
sizes are generally smaller than raster
graphics.
 Best choice for creating type or logos
where crisp outlines are needed since
clarity is not lost when scaled/resized.

14. Common Image/Graphic FilesCommon Image/Graphic Files
 BMP: Bitmap is the standard Windows
image format
 GIF: Graphics Interchange Format;
designed to minimize file size and
download (electronic transfer) time

15. Common Image/Graphic FilesCommon Image/Graphic Files
 JPEG: Joint Photographic Experts Group;
compresses file size by selectively discarding
data, unlike GIF format, JPEG retains colour
information.
 TIFF: Tagged-Image File Format; used to
exchange files between applications and
computer platforms; “flexible” bitmap image
supported by virtually all paint , image
editing, and page-layout applications.

16. Common Image/Graphic FilesCommon Image/Graphic Files
 AI: Adobe Illustrator; vector files that are
created using Adobe Illustrator.
 CDR: CorelDRAW users create/save vector
files that use the “cdr” default.
 Both CorelDRAW and Adobe Illustrator permit the
user to export files as a different file/extension. This
is particularly useful as software versions are not
backword compatable, i.e., a CorelDRAW 12 file can
be opened in CorelDRAW X5, but a CorelDRAW X5
file may not be opened in CorelDRAW 12.
