Color images group

Compression: Select the compression to use for the color images. Flate is a lossless com-

pression 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 com-

pression 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.

Downsampling: 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 Color 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 color in each sample area and to replace the entire area with a pixel of the

average color. 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.

Resolution: Select the resolution to use for color images. Note that this setting has an

impact on the color down-sampling process.
