Getting Images into Photoshop and ImageReady
If you turn on resampling for the image, you can
change print dimensions and resolution indepen-
dently (and change the total number of pixels in
the image). If you turn resampling off, you can
change either the dimensions or the resolution—
Photoshop adjusts the other value automatically to
preserve the total pixel count. For the highest print
quality, it's generally best to change the dimen-
sions and resolution first without resampling.
Then resample only as necessary.
To change the print dimensions and resolution of
an image:
Choose Image > Image Size.
1
Change the print dimensions, image resolution,
2
or both:
To change only the print dimensions or only the
•
resolution and adjust the total number of pixels in
the image proportionately, make sure that
Resample Image is selected. Then choose an inter-
polation method. (See "Choosing an interpolation
method" on page 96.)
To change the print dimensions and resolution
•
without changing the total number of pixels in the
image, deselect Resample Image.
3 To maintain the current proportions of image
width to image height, select Constrain Propor-
tions. This option automatically updates the width
as you change the height, and vice versa.
4 Under Document Size, enter new values for the
height and width. If desired, choose a new unit of
measurement. Note that for Width, the Columns
option uses the width and gutter sizes specified in
the Units & Rulers preferences. (See "Using rulers,
the measure tool, guides, and the grid" on
page 74.)
For Resolution, enter a new value. If desired,
5
choose a new unit of measurement.
Click OK.

To return to the original values displayed in the
Image Size dialog box, hold down Alt
(Windows) or Option (Mac OS), and click Reset.
To view the print size on-screen:
Do one of the following:
Choose View > Print Size.
•
Select the hand tool or zoom tool, and click Print
•
Size in the options bar.
The magnification of the image is adjusted to
display its approximate printed size, as specified in
the Document Size section of the Image Size dialog
box. Keep in mind that the size and resolution of
your monitor affect the on-screen print size.
