Importing colour
pictures to PageMaker
The
resolution of a colour image should be 274 to 300 dpi, when the
screen ruling is 60 lines per centimetre. A general rule is that
the images should be converted to CMYK. For this, Acta Print's web
site offers ICC colour profiles for downloading. With these
profiles the colour separations can be optimised for Acta Print's
printing machines. The profiles, based on colour separation, have
been separately created for gravure and offset machines using
different paper types.
The images
should be saved as TIFF. If there are clipping paths in an image (be
ware of too complicated paths!), it should be saved as a
one-file EPS (5-file DCS is not allowed!) The images should
not, without a particular reason, be compressed to JPEG files, as
this would lower the image quality. A TIFF file may be LZW
compressed, should the available disk storage be limited.
In PageMaker
it is possible to stretch, rotate and crop the pictures, but
scaling should keep within 60 to 120 percent limits.
Importing grayscale
images to PageMaker
For greyscale pictures, the guidelines
concerning resolution, saving and scaling are identical to those
for colour images. One should keep in mind that ICC colour
profiles also affect the formation of a greyscale image dot.
Importing line art
PageMaker
The
resolution of line-art pictures should be 1200 dpi, and never
below 600 dpi. As a rule, files should be saved as TIFF, images
with clipping paths as EPS.
For
line-art in TIFF format, in PageMaker one can define colour, in
addition to cropping and scaling. In process colour jobs the
colour should be CMYK, and in spot colour jobs in spot colour
mode.

been limited to 85%, the total ink has been limited to 370%.
