Saving Color Values

You can sort the list by clicking the column headers. This allows
you e.g. to quickly find the colors with the largest delta E values.
If you frequently fine-tune the same colors, it is a good idea to save them
to a file. Such files are referred to as color samples (*.prb). Having
loaded a *.prb file you can easily reselect the colors by clicking on a list
entry. This is much more convenient than having to use the sliders or
typing the values in.
You can also create reference files (*.ref) for user-defined test charts
from the colors selected during fine tuning. A reference file defines the
CMYK values of the color patches to be measured.
1. If you want to add colors to an existing file, click LOAD and open the
*.prb or *.ref file. Otherwise click RESET SAMPLE (if available) to
make sure no color value file is loaded.
2. Specify the CMYK color you want using the sliders or input boxes on
the left (see Fig. 18-10), then click ADD ENTRY. You may be asked
whether you want to create a color sample (*.prb) or reference file
(*.ref).
3. Select another color and click ADD ENTRY. Repeat this until you have
added all colors you want.
4. Click SAVE SAMPLE to save the file. Type a name, then click SAVE. The
appropriate file extension (prb or ref) is added automatically.
Tip: If you have printed an image and measured specific colors that need to
be optimized, you should note down the color values, select them in
ORIS Press Matcher⁄⁄Web and save them as a color sample.
