Fine Tuning
Step 7: Manual Fine Tuning
Step 7.1: Evaluate Match and Measure Colors
1. Print an image on your printer and also on the target device to be
matched.
2. Compare the results under standard lighting conditions (D50,
5000°K).
3. If you feel that particular colors are not perfectly matched, measure
the CMYK values of these colors.
You can use ORIS PDF Tuner for this purpose. Open the image,
place the cursor on the color area and note down the values displayed
in the COLOR window.
A demo version of ORIS PDF Tuner is installed together with ORIS
Press Matcher⁄⁄Web and can be started by double-clicking the file
…\Program Files\CGS\ORIS PRESS MATCHER WEB\ORIS Hotfolder
Manager\DDS.EXE. The program is fully functional for 30 days after
installation.
Step 7.2: Selective Color Corrections
1. Open the COLOR VALUE CORRECTION dialog (see Step 3).
2. Select the CMYK colors you have noted down.
Use the sliders on the left-hand side or enter the CMYK values into
the input boxes next to them.
Color corrections are only fully applied to such values that are
multiples of 5 or 10, respectively (such as C15 M20 Y45).
Intermediate values are interpolated. See also page 18-15.
To be able to reselect the CMYK colors conveniently, you should
save them as a color sample file (*.PRB) using ADD ENTRY (see
page 18-19).
3. First evaluate the simulation visually (PRINT and PROOF color boxes),
and then numerically (values at the top right). With a good color
match, the two colors look identical and delta E approaches zero.
