Light Adjustment since the viewed places randomly vary. This means that the Ambient Light
Adjustment effect works best when printing in large format. That is why we incorporated it as a
necessary feature in iPF8000S and iPF9000S.
Q. Has Ambient Light Adjustment feature been strongly demanded?
In case that a print looks different in color when posted although it appeared just as a user
expected at production site, most users have unwillingly accepted the phenomenon.
(Professionals sometimes try to make a print considering color appearance change, based on
their color matching expertise and experiences. However, that is very difficult and rare.) This
problem seems to occur because users have not been provided with a technology in a
user-friendly way that adjusts colors before printing in accordance with the specified viewing
environment to ensure favorable color reproduction. As a matter of fact, we often hear from our
clients that they have a problem with prints whose colors look different depending on the viewed
place. In response to such potential needs, we provide Ambient Light Adjustment feature this
time.
Q. In which case is Ambient Light Adjustment useful?
For instance, it is quite useful when you wish to post the common designed poster at each branch
of a chain store. In combination with the Variable Print that has been featured in PosterArtist,
each poster can be printed with its store name, address, and detailed map with appropriate
ambient light setting (for underground branch, outdoor branch, etc.).
Q. It is said that Ambient Light Adjustment adjusts color differences resulted from different
lighting conditions. How does it respond to those various conditions?
The Ambient Light Adjustment feature requires information on ambient light in an environment
where a print is displayed or posted. Nowadays, people use various types of lighting, and ambient
light conditions include such elements as wall colors, ceiling colors, window sizes, and window
orientations. Consequently, it must respond to diverse conditions.
There are two methods provided to assess ambient light information for users of iPF8000S and
iPF9000S. Users can select either of them according to their print purpose or levels of operational
skills and knowledge.
