Welcome to Desktop Jeopardy!
  • 3 teams
  • 2 questions to each team
  • Each question worth 10 points
  • If that team misses you have the opportunity to steal

4. The file size of a 72 dpi file that is increased to 144 dpi will be ________times the size of the original.

5. For printed material to display natural looking halftones it is recommended that the image dpi is ______ times the line screen used in the printing method.

6 in quarkxpress the tool needed to edit elements within a selected text or picture box is the tool
6. In QuarkXPress the tool needed to edit elements within a selected text or picture box is the __________ tool.
raster vs vector
Raster vs. Vector
  • All computer images come in either Vector or Bitmap formats
  • Each has it’s own advantages and disadvantages
raster or bitmapped images
Raster or Bitmapped Images
  • Image defined pixel by pixel and its resolution is fixed
  • They are called resolution dependent
vector illustration images
Vector/Illustration Images
  • A vector or object-oriented image is a mathematical equation where each object is defined by points connected by paths.
  • They are resolution independent
vector based applications
Vector-Based Applications
  • Adobe Illustrator
  • Macromedia Freehand
  • CorelDraw
  • These images can be save in a variety of formats so that they can be used and displayed in other in other types of programs
resolution independent
Resolution Independent
  • They retain their characteristic shapes at different sizes and output resolutions
file formats for web
File Formats for Web
  • GIF (.gif)
  • JPEG (.jpg)
tiff files in quarkxpress
TIFF files in QuarkXPress
  • Image Control: One-bit (black& White) and grayscale images can be assigned a color in Xpress. A grayscale TIFF can also be edited with contrast and halftone commands in the Style menu

TIFF files in QuarkXPress
  • File Size and Compression: Typically uncompressed TIFFs are about 20% smaller than EPS files. A TIFF can be saved with non-lossy LZW compression to make their file sizes smaller.

TIFF files in QuarkXPress
  • Onscreen Display: Xpress generates a low-resolution proxy to preview an imported TIFF. The quality of this preview depends on preset preferences.

TIFF files in QuarkXPress
  • Cropping: If you crop a TIFF inside Xpress, the printer processes only the viewable data

TIFF files in QuarkXPress
  • Downsampling: QuarkXPress will downsample all TIFFs to two times the halftone screen frequency
eps files in quarkxpress
EPS files in QuarkXPress
  • An EPS file can be a bitmap/raster or an object-oriented/vector graphic depending on which program was used to generate the EPS.

EPS files in QuarkXPress
  • Image Control: An EPS graphic has already been converted to PostScript Which means that this is a locked file

EPS files in QuarkXPress
  • File Size and Compression: An EPS file is typically 20% larger than an uncompressed TIFF file
eps files in quarkxpress24
EPS files in QuarkXPress
  • Onscreen Display: The preview is built into the structure of the PostScript. The speed of the display is dependant upon the preview option chosen when creating the EPS file

  • Cropping and Downsampling: Xpress always sends everything to the printer. This can significantly increase the printing time.
