For a Z9+, why do chromatic blue & chromatic green look purple and pastel green in diagnostic image?  see attached (although not very good pics)

Have you run the color calibration routine for the paper you are using? It prints a complete set of color watches and then scans them with the built in spectrophotometer to ensure the color is balanced.

Thanks. No, I have not run the color calibration on the "bright bond"; I do not know if I can run the color calibration on it--I guess if necessary I could reload the paper under some "photo paper" name.  I assume I would need some photo paper for color calibration but not sure.  Will have to look it up.  Thanks again.    ....I assumed the diagnostic image was simply a set predetermined appearance for all colors and did not think about color calibration.

I ran the "color calibration" on the "bright bond"--in the printer I entered some type of "glossy photo" to get it to do the "color calibration".  There was improvement.   Purple and what appears to be more chromatic green were more vibrant.

 

Perhaps the purple in the diagnostic image is just inherent, don't know.

 

Pic attached.

 

Chromatic blue still looks purple.  Maybe it is a matter of having the right paper.  I did not want to go to the trouble of obtaining and loading glossy photo.

 

Also, color calibration got rid of some banding in some of the yellowish grayish print on the same paper.

 

Thanks.

Two other settings that can help eliminate banding is to run a paper advance calibration with the paper you are using and to print in high quality mode.

Repairatrooper, thanks for the additional advice.   I have been at least doing the paper advance calibration, and so far have only been doing internal prints which I assume are best mode.   On the "design" internal print, the color calibration seemed necessary to get rid of the banding, and it looked OK even on bright bond.

 

Thanks again.
