Before the adjustment After the adjustment
The hues of highlighters are not accurately
reproduced. The areas marked with 2 different
colored highlighters are reproduced in the
same hue. They are indistinguishable.
The areas marked with 2 different colored
highlighters are accurately reproduced
and distinguishable on the copy.
Explanation
When an original containing text or areas marked with highlighters is copied, their hues may sometimes not be
accurately reproduced on the copy. The inks of highlighters are special. Therefore, their hues cannot be accurately
reproduced. To reproduce the hues of similar highlighters, such as yellow and green, while producing sharp
contrasts on the copy, perform the color adjustment (color balance adjustment or RGB adjustment) and color
density adjustment. Also, the e-STUDIO281c/351c/451c allows the setting specifically for reproducing text or
areas marked with highlighters. It can be assigned for a button in the "ONE TOUCH ADJUSTMENT" option.
Procedures
* You can start with any of the procedures. But it is recommended to perform the procedures in order, as listed
below. You can use one procedure in conjunction with another. But if this changes the image quality more
than required or loses effectiveness of the adjustment, restore the settings made in the previously used
procedure to the original. Then perform the next procedure.
* Procedure (1) is used by the service technician, and by the user.
* Procedures (2) and (3) are used by the service technician only.
(1) Perform the color balance adjustment or RGB adjustment to adjust the hue in general.
* For further information regarding the adjustment procedures, refer to procedure (3) in 2.2 To Closely Match
with the Color Balance of the Original.
After adjusting the hue, copy and check the copy image quality.
If further image quality adjustments are still necessary, the service technician must use the next procedure.
