User's Guide
Cause
Print quality is poor, uneven,
too light, or too dark.
The color is not the same as
another printer.
What to do
Have you made color adjustment settings?
The color is produced differently because the output devices (such as
display, printer) are different. In order to reduce the differences in color
between each device, perform color adjustment.
See "Color adjustment by the printer driver" on page 75.
Have you compared the printing result with the image on the display
monitor?
Since monitors and printers produce colors differently, printed colors will not
always match on-screen colors perfectly.
❏
Televisions and monitors produce a range of colors by combining the 3
colors known as the 3 primary colors of light, red (R), green (G), and blue
(B). When none of the lights are shining, the result is black, and when all
3 colors are shining, the result is white.
❏
However, color gravure printing and color printers use a combination of
the 3 primary colors of pigment, yellow (Y), magenta (M), and cyan (C).
When no color is applied, the result is white, and when all 3 colors are
mixed evenly, the result is black.
❏
Printing a scanned image necessitates the changes from the original
image (CMY) to the monitor (RGB) then to the print (CMY), making color
matching even more difficult. In this case, color matching between the
devices is handled by ICM (Windows) or ColorSync (Mac OS X).
When using a color management system such as ICM (Windows) or
ColorSync (Mac OS X), have you set a monitor profile?
For proper management, the input devices and applications used must
support ICM (Windows) or ColorSync (Mac OS X). Also, it is necessary to set
the profile for the monitor that you are using.
See "Using Color Management" on page 70.
Did you open the front cover during printing?
If the front cover is opened during printing, the carriage stops suddenly
causing unevenness in the color. Do not open the front cover during
printing.
Does INK LOW appear on the LCD panel?
The print quality may decrease when the ink is nearly expended. Replace
the ink cartridge with a new one. If the print quality is not good after
replacing the ink cartridge, perform head cleaning a few times.
Have you set color matching for each device?
Each printer has a color profile and the same data may be printed with
differing colors on each printer. Color matching minimizes the differences
between colors as much as possible.
The printer driver of this product has a color matching function. If you print
with Epson's recommended settings the print colors will differ between
printer models. If you want to print with closely matched colors, try using
color management. You can also load color profile information for this
printer from an application.
See "Using Color Management" on page 70.
For other devices, please refer to the manual of the device or application
for color matching.
