LESSON 4 Reading and Working with PDF Files
You can use the initial view settings to determine how viewers initially see docu-
ments that you create and distribute.
6 Close your ﬁle and reopen the original work ﬁle, Protocol.pdf.
About the onscreen display
Take a look at the magniﬁcation ﬁeld in the Common Tools toolbar at the top of the
document window. 周e magniﬁcation does not refer to the printed size of the page,
but rather to how the page is displayed onscreen. Acrobat determines the onscreen
display of a page by treating the page as a 72 ppi (pixels-per-inch) image. For
example, if your page has a print size of 2-by-2 inches, Acrobat treats the page as if
it were 144 pixels wide and 144 pixels high (72 x 2 = 144). At 100% view, each pixel
in the page is represented by one screen pixel on your monitor.
How big the page appears onscreen depends on your monitor size and resolu-
tion setting. For example, when you increase the resolution of your monitor, you
increase the number of screen pixels within the same monitor area. 周is results in
smaller screen pixels and a smaller displayed page, since the number of pixels in the
page itself stays constant.
Reading PDF documents
Acrobat provides a variety of ways for you to move through and adjust the onscreen
magniﬁcation of a PDF document. For example, you can scroll through the docu-
ment using the scroll bar at the right side of the window, or you can turn pages as in
a traditional book using the Next Page and Previous Page buttons in the Common
Tools toolbar. You can also jump to a speciﬁc page.
Using Read mode
As you saw in Lesson 1, Read mode maximizes the screen space available to a docu-
ment in Acrobat so you can read it more comfortably.
1 Choose View > Read Mode. In Read mode, all elements of the work area are
hidden except the document pane and the menu bar.
2 Use the Page Up, Page Down, or arrow keys on your keyboard, or use the scroll
bar to move through the document.
