Title: K CHANNEL ISSUE (PK ON SC-P600) Solarised looking prints
Post by: Clark on March 15, 2020, 12:58:34 pm

Hi all. I am having a strange issue with my EPSON SC-P600.

Prints are looking very obviously wrong (with dark areas lacking a lot of density and looking blue / solarised).

I've tried printing a test swatch, with no colour management, and the result is strangely interesting - the black channel is not black, but has a dark outline!? (edit - the poor quality overall in the attachment is due to just a re-used sheet of plain paper for the swatch test).

Another thing to note is when printing plain text documents, which I occasionally have to do, the text appears a mid-blue instead of black.

Have a look at the attached files. If anyone has any idea what this could be, or what I could do as a next step to identify the problem, would be very appreciative.

A few probably silly questions....

- what kind of paper are you printing to?
- what ICC profile are you using to print with?
- what software are you printing from?

Nozzle check is perfect?

Printing to a couple of slightly different types of Ilford Semi-Gloss, using Ilford profiles. I use Photoshop to print with. I have the proper driver installed with all the extended settings available.

I have already tried:

Re-installing printer drivers.
Running head-clean cycle and leaving to settle for 24 hours.
Printing from another computer.


Nozzle check is perfect Dan, yes. That's the strangest part of it. When I first saw the problem, I ran a nozzle check and was very surprised to see it shows no signs of a problem.
