7-14 Imaging Basics _______________________________________
The general rule of thumb is that a 100 dpi per scale factor ratio will
maintain the resolution of the original image without pixilation. For
example, an 8 1/2" x 11" original image scaled three times its
original size (or 4x if you have the auto reduction feature enabled)
will produce an E size poster.
Occasionally you may have an extremely sharp close up image with
lots of details. In this case, the image can be extended below that
scale factor to 50 or 75 lpi per scale factor before pixilation occurs.
XANTÉ Scaling is available at the PPD (PostScript Printer
Description) file level under Options in the Print menu.
Page Design
Advanced imaging includes not only the mechanical side of printing,
but also the elements of page design. Your controller with true
Adobe PostScript takes care of most of the mechanical side,
allowing you such freedom as scaling, rotating, and filling text and
graphics. However, a basic understanding of terms and elements of
page design can help you add finishing touches for a truly
professional image.
The rest of this chapter deals with some of the language and
elements used in desktop publishing page design.
Typefaces and Fonts
Two very important terms to understand are typefaces and fonts.
These terms often are used interchangeably which can lead to
confusion sometimes. A font is actually a subdivision of a typeface.
Typeface refers to the style of printing type, not the size. The style
includes design elements such as spacing, stroke, and weight which
are covered later in this chapter.
A font is one size of a typeface and includes all the available
characters of that typeface.
