    Hello

    sometimes im getting these horizontal lines in print. I did a photo, but it doesnt cleary show them.

    I can see that ink is layed differently every second line...

    It happens occasionaly... i did strong cleaning, i maually clean head yesterday. turn up heaters...

    Probably when i will start new print these lines will be gone... as usually.

    Im just wondering why they show up???

    Sounds like chromatic banding.
    Ink is layed down in different order during each pass of Bi-directional printing.
    I.e. from right to left it may be KCMY
    But from left to right it will be YMCK.

    Printing Uni-directional will solve this issue.
    Raising or lower the heater settings can help as well, usually lowering the temps.

    I have the same issues on certain colors. Seems to be mostly dark blues and greens. I havent sorted it out. Seems to happen randomly

    Hard to tell, but it looks like chromatic.
    Sometime (depending on media, environment) higher temperatures can help.

    Also important that Bi-direction alignments are good.

    ok, im going throug google with this chromatic banding... I noticed, that this is pretty comonn problem with printers. Everybody are suggesting uni-directional printing as solution. ok... if you have time, its no problem... but if you are in hurry like me, than that could be a problem... but ok... lets say that is only solution i've got...

    I would like to know why some prints that i did doesnt have these bandings? It was same file, same profile, same vinyl, same temperature,...
