Expected Production Resolution
Use these parameters to specify the resolution expected to be used for
producing the finished page.
• Use the CT IMAGES box to enter the resolution to be used for
images, gradients and other low-res elements.
• Select a factor from the LW FACTOR list to specify the resolution of
high-res elements such as tints, text and linework. The CT IMAGES
resolution will be multiplied by this factor.
These specifications are used as default values when converting the layout
to another format (EXPORT function, see page 3-1).
Specifying the expected resolution for CT IMAGES allows you to prevent
a deterioration of image quality when exporting the layout. Image quality
may deteriorate due to resampling, which is done in the following cases:
• The image resolution differs from the output resolution
• Images were rotated on the layout (except by 90°, 180° or 270°)
• Images were moved using the TRANSFORM function (see page 16-4)
Images can be scaled automatically in a way that their resolution is set
to the expected output resolution, thus avoiding the need for resampling
(provided that the images are neither rotated nor moved using TRANS-
FORM and that the output resolution is actually used). There are various
ways to do this:
• Enable the AUTOMATIC SCALE 1 option in the LAYOUT PARAMETERS
dialog (see page 5-10). Now, whenever you place an image on the
layout, it will be scaled according to the specified CT IMAGES resolution.
However, existing image layers are not modified.
