  • Yellow shadow in Red.

    Posted by Martin Oxenham on November 21, 2013 at 10:16 am

    We’ve had this problem a while now and VTS engineers have looked at it and can’t find whats wrong. Wondering if anyone else has had this problem.
    We get a Yellow bleed around the edge of anything printed Red. Have tried everything but to no avail. Difficult to capture on camera. Any ideas !

    FRACTIONALLY misaligned heads for bi-directional print.

    Got it too…live with it though.

    Does it disappear when you print super slow uni-directional?

    That’s weird. The picture looks as though it’s just the box that shows the overspray and the text is fine. Does it do it in all print modes?

    The yellow edge is on the top and bottom of each red print so presumably the graphic was rotated before printing. So I would double check the bidirectional as David said.
    Suppressed vts not fixed it yet. Unfortunately just cost me a new head to cure not too dissimilar problem.

    No it is actually around all of the letters as well. It shows up more on the box as its such a thin line. And it is in all directions.

    It does look like a bi directional calibration problem to be honest. However, it could be an electrical fault on the printhead. I was looking at a Mimaki only this week that had a similar thing on the cyan. The test draw was perfect but when printing 720 x 720 it would give a shadowing effect. 360 x 720 was fine. That’s why I was asking if it’s the same in all print modes.

    Get in touch if you would like to discuss it.
