Setting Item Details
dry without using the ventilation fan.
Ventilation Fan Configures the drying time and airflow for the ventilation fan.
Time Configures the drying time for the ventilation fan for each pattern.
The number of lines that are dried at one time by the ventilation fan varies
depending on the size selected in Pattern Size.
As the time increases, the adhesion of the ink improves and the color tones
become more stable.
Reduce Drying Time Selecting this check box reduces the drying time.
Once the time configured in the Color Measurement Env. sheet in the
Preferences dialog box has elapsed, color measurement proceeds without
performing any further drying with the ventilation fan.
Specify a time that offers sufficient drying by air drying in the Preferences
dialog box. If you perform color measurement while the ink is not dry, the
measurements may not be correct.
The Preferences dialog box is displayed when you click Preferences in the
File menu.
If the number of patterns is small, drying will finish in a shorter amount of
time than the time configured in the Preferences dialog box. If this happens,
the drying time will not be reduced even if the Reduce Drying Time check
box is selected.
Airflow Selects the airflow of the ventilation fan.
Air Drying Sets the period between the color chart being printed and the color
measurement starting.
If the Dry Separated Chart check box is selected, printing and air drying
are repeated for each separated color chart. This makes it harder for the color
charts to become scratched or soiled, but also increases the time taken by the
operation.
If the Dry Separated Chart check box is clear, printing and air drying the
color chart are performed once. This reduces the time taken by the
operation, but may scratch or soil the end of the color chart and paper.
However, this does not affect the color measurement results.
Position of Ventilation Fan If you are using paper that has a tendency to curl or paper that does not dry
easily, select High so that the paper does not come into contact with the
paper presser.
Note that when High is selected, we recommend that you set the Time
longer and the Airflow stronger compared with when Standard is selected
because of the larger distance between the ventilation fan and paper.
