For example, when you are reading for 2%, if the box labeled 7
measures 2%, enter the number 7 in the corresponding box.
Note: The calibration page blocks are numbered from 0 to
255. You may have to check several blocks to find the
one that most closely matches the percentage in the
Densitometer Data Entry window.
Also, it is not necessary to measure for each coverage
value, but that is recommended to achieve more
accurate results.
4. Click Graph to display your printer’s linear curve.
5. Click Linearize to continue. The Linearization window
reappears (3.15)
Note: If you need to stop linearization (for example, to
change the media type), click Cancel.
6. Click Save to Disk (fig. 3.15) if you want to save the data file
for future use. Then, specify a new file name and select a
folder for saving the file. Click Save. Otherwise, skip to step 7.
7. Click OK. The Linearization window closes.
Note: To verify linearization, click the Print Verification Page
button (3.15) before you close the Linearization window.
When the new page prints, compare it to the original
calibration page to verify the gamma correction; you should
see an improvement in gray scale progression.
Advance Gamma Curve Control
If you are an expert user, you may want to adjust image lowlights,
midtones, highlights, and details in a gamma curve using the Advanced
option in the Linearization window.
Note: You cannot see advanced window adjustments on screen.
Unless you are an expert user, you always should make these
adjustments thorough an application.
