you suspect that the data may contain parentheses, you should use a Run script action task
(see Run Script Action Task Property) with a Strip() function to strip them out.
l Keywords: You may enter keywords for the document. Since this is a variable property box, you
may use variables and data selections and let PlanetPress Workflow interpret this information at
run-time.
l Monochrome images group
l Monochrome compression: Select the compression to use for the monochrome images. Flate
compression is lossless, so no data is lost during compression. Flate Mono works well on
images with large areas of solid shades or repeating patterns, such as screen shots and simple
images created with paint or drawing programs. CCITT typically yields the best compression of
monochrome images. It is the compression method developed for fax transmissions. Note that
configurations that were created with an earlier version of PlanetPress Workflow and that
included tasks set not to use any compression will by default be set to use the Flat compression
method.
l Monochrome resolution: Select the resolution to use for monochrome images.
l Grayscale images group
l Grayscale compression: Select the compression to use for the grayscale images. Flate is a
lossless compression method, so no data is lost in the process. It works well on images with
large areas of single shades or repeating patterns, such as screen shots and simple images
created with paint or drawing programs. JPEG removes image data and may reduce image
quality, but may be suitable for continuous-tone photographs containing more detail than can be
reproduced onscreen or in print. Since JPEG eliminates data, it can achieve much smaller file
sizes than Flate compression. Select Auto to let the application choose the best compression
method automatically. Note that configurations that were created with an earlier version of
PlanetPress Workflow and that included tasks set not to use any compression will by default be
set to use the Flate compression method.
l Grayscale down sampling : Select the down sampling option. down sampling reduces image
size by breaking images down into small areas in which multiple pixels are replaced by single
pixels. The Grayscale resolution you enter in the following box is used to control the down
sampling process. Select None to prevent grayscale down sampling . Select Average to average
pixel shades in each sample area and to replace the entire area with a pixel of the average
shade. Select Subsample to use a pixel in the center of the sample area and replace the entire
area with that pixel value. This method is significantly faster, but results in images that are less
smooth. Select Bicubic to use a weighted average to determine pixel shades. This method is the
slowest but most precise and results in the smoothest tonal gradations.
