Difference of + and – options
When Guide Print-RGB is printed with all three RGB
parameters set to 0, seven images are printed. The center
picture is the reference picture with all three RGB
parameters set to 0, and each of the surrounding six
pictures has one of the three parameters set to +3 or –3.
This section explains what the + and – represent.
A picture consists of RGB data, which is a numeric
representation of the intensity of light of each color. A +
sign means strengthening the light, while a – sign means
weakening the light. A notable phenomenon on the +
side is saturation of data (light). This phenomenon is
very useful when the background has to be white, as
white remains white even when the value is increased to
the + side.
• + setting
Setting the R parameter to +3, for instance, means
strengthening the RED element of light. Therefore, the
picture looks reddish overall. In addition, the picture
becomes brighter because the total amount of light
increases.
However, some portions remain unchanged. These are
the portions that totally lack the RED element, for
instance, pure green, pure cyan, pure blue, neutral tints
in between, or total black, and the portions where the
RED element has saturated on the picture, for instance,
pure reddish purple (magenta), pure red, pure yellow,
neutral tints in between, or total white.
• – setting
Setting the R parameter to –3, for instance, means
weakening the RED element of light. Therefore, the
picture looks tinged with cyan, which is the
complementary color of red. In addition, the picture
becomes darker because the total amount of light
decreases.
Unlike the + case, the overall picture is tinged with cyan
including those portions where the RED element has
saturated, for instance, pure reddish purple (magenta),
pure red, pure yellow, neutral tints in between, or total
white. A white background or clothes look tinged, too.
Example 1: Reducing yellowness
To reduce yellowness from the subject, Guide Print-
RGB advises you to shift the B parameter to the + side.
Example 2: Adding yellowness
To add yellowness to the subject, Guide Print-RGB
advises you to shift the B parameter to the – side.
However, it should be noted that even a white portion
becomes yellowish. To avoid this effect, shift the L
parameter to the + side as much as the shifting of the B
parameter to the – side. In effect, this is the same as
shifting the R and G parameters to the + side without
changing the B parameter. Here, it should be noted that
the overall brightness increases.

Image Processing Time

When printing images shot by the camera, image data
are transmitted from the camera to the printer, and the
printer processes the received data then executes
printing. The time required for data transmission and
printing varies according to the print size and the size of
print paper used. It also varies according to the distance
of data transmission and radio wave conditions.
Data transmission time
While image data are transmitted from the camera to the
printer, "TRANSMITTING" is displayed on the LCD,
and no operation on the camera is allowed. The
estimated time required from when the PRINT button of
the camera is pressed for image data transmission till the
next operation on the camera is enabled is as shown
below:

When data for one picture are being transmitted, while
printing processes are displayed on the operation display
of the printer, you can cancel transmission by pressing
ENTER of the control button. However, transmission of
several pictures cannot be canceled.
Printing time
The estimated time required from when the PRINT
button of the camera is pressed until the printer receives
image data transmitted from the camera and finishes
printing one sheet is as shown below:
