Inaccurate or unexpected colors
●
UV inks have a limited shelf life. Expired inks may under go a color shift. Ensure that the expiration
date marked on the ink packaging has not passed. Replace any expired ink.
●
Shaking the ink can compensate for settling of the ink components, and gradually correct a color
shift (after several prints, depending on the amount of settling that has occurred).
●
Verify that you are using the color profile that matches the media, or most closely matches the
media type, you are using.
●
Perform a color calibration (linearization). See Linearization on page 63 for details.
● Check for missing jets. See Check jet health on page 104 for instructions.
●
If the problem consists of color differences between your computer monitor and printed output,
consider calibrating your monitor according to manufacturer's instructions, and viewing prints in
natural sunlight or under full-spectrum lighting.
●
Ensure that all of the images and the document itself have been saved in the same color space.
Refer to your application user documentation for instructions.
●
Operating the printer outside the stated specifications for temperature (see Specifications
on page 92 ) can cause the printheads to fail to refill predictably, resulting in shifted colors.
