SolJet Pro III - Grays Printing with Magenta Overcast (Picture Attached)

[John A]

I've had this machine about a year and when I first got it the print quality was spectacular.

About 2 months ago I noticed it started to print with magenta in all of the gray prints, so for the past 2 months I've missed out on a lot of work because I only took work that didn't have gray.

I've attached 2 pictures.

Picture one is the test print. I see no real issues here, just a minor drop out in cyan.

Picture 2 is a print across the entire length of the printer with the following values.

100%K - 90%K - 80%K - 70%K - 60%K - 50%K - 40%K - 30%K - 20%K - 10%K - 100%Y - 100%M - 100%C

As you can see, all of the black values have magenta in them. Cyan, Magenta, and Yellow appear to be printing perfectly. (This print was done after the test print.)

Any input on this would be very appreciated.

Looks like a profiling issue as you have no problems when a test print is done. But only when the colors are run through your rip. I would suggest checking your rendering intents.

How would I go about doing that?
