Difference between selecting + and –
When you print a Guide Print-RGB with each of the
RGB parameters for the center picture set to 0, two
simulation pictures for each RGB parameter (with the
respective parameter set to +3 and –3 and the remaining
two parameters set to 0) are printed around the center
picture. The following explains the meaning of the + and
– symbols.
The R data, G data, and B data that make up the picture
data are digitized values representing the strength of
light of each color. The + setting is for strengthening the
light of the corresponding color. The – setting is for
weakening the light of the corresponding color. Data
(light) saturation can be obtained with the + setting.
When you need a white background, this feature enables
you to get the desired results without changing the
white.

• Setting in the + direction
When the R parameter is set to +3, for example, the light
of the red component is strengthened, giving the overall
picture a tinge of red. Since the amount of light also
increases at the same time, the brightness of the picture
increases by the corresponding amount.
However, some parts of the picture do not change no
matter how much the light is strengthened. These
include parts of the picture with absolutely no light
components (such as pure green, cyan, and blue parts,
their intermediate colors, and deep black parts), and
parts of the picture with saturated light components
(such as pure magenta, red, and yellow parts, their
intermediate colors, and bright white parts).

of the red component is strengthened, giving the overall
picture a tinge of red. Since the amount of light also

• Setting in the – direction
When the R parameter is set to –3, for example, the light
of the red component is weakened, giving the overall
picture a tinge of cyan (the complementary color of red).
Since the amount of light also decreases at the same
time, the darkness of the picture increases by the
corresponding amount.
This setting differs from the + setting in that a tinge of
cyan is added to parts in which light components are
saturated such as parts of pure reddish-purple
(magenta), red, and yellow or their intermediate colors
and bright white. This occurs especially in cases where
the background is white or the subject is wearing white
clothes.

Specific example 1: Removing yellow
To remove yellow from the subject, we recommend
setting the B parameter to a + value in the Guide Print-
RGB.

However, you need to understand that the concept of
weakening the light involves adding a tinge of yellow to
white parts. To avoid this, set a plus value for the L
parameter that is equivalent to the minus value set for B
parameter. This has the same effect as setting plus values
for the R and G parameters without changing the B
parameter. The point to note here is that the overall
brightness increases.
