Previewing a page
A. Label B. Registration marks C. Crop marks

To view the print size on-screen:
Choose View > Print Size.
The magnification of the image is adjusted to
display its approximate printed size, as specified in
the Print Size section of the Image Size dialog box.
(See “Changing the print dimensions and
resolution of an image” on page 49.)
About resampling
Resampling refers to changing the pixel dimen-
sions (and therefore file size) of an image. When
you downsample (or decrease the number of
pixels), information is deleted from the image.
When you resample up (or increase the number of
pixels), new pixel information is added based on
color values of existing pixels. You specify an
approximation or interpolation method to
determine how pixels are added or deleted. (See
“Choosing an interpolation method” on page 51.)
A. Resampled down B. Original C. Resampled up
Keep in mind that resampling can result in poorer
image quality. For example, when you resample an
image to a higher resolution, the pixels interpo-
lated from the new image data can make the image
appear blurry or out of focus.
