    I have noticed the print quality of the Mimaki has gone really mottled and the test print doesn't seem as crisp as it use to. The black seems to seep into the yellow.

    Ignore the smudge the material wasn't very flat.

    Using corel draw to Rastelink
    have played around with the heat settings going from 30-50 degrees
    slowed the print down to normal
    resolution changes
    recalibrated spray and alignment

    I am using Jetbest ink cartridges for a year now. The temp of the room can get around 14 deg if that has any effect to the ink?

    Any help would be appreciated. I have scoured the internet to no avail. Thanks.

    Did your heaters accidentally get turned off?

    Are you printing in uni or bidir? Try to switch in unidirectional if result much better in unidir then recalibrate your bidir or check the carriage height could be too high.

    It looks like either the heaters are off or the profile is laying down too much ink. Not a bad idea to check your alignments as well.

    Thanks for the suggestions guys.

    Heaters are on as I have tested them from 30-50 deg C
    I recalibrated the print (drop pos correct) and media comp
    Adjusted the height of the head to lowest position
    Not tried uni direct but I have always printed in bi direction and never had mottled print
    default speed is usually fast but I have slowed it down to normal and it is sloooow so if I make it unidirectional too its gonna be even more sloooooooow

    Media is new gloss vinyl and matt vinyl (poli-tape)

    It baffles me as I think I have tried everything except change the ink.

    If you are talking 14 degrees F then that is going to affect the ink and the way it comes out of the head. I'm willing to bet that's the issue. Humidity is probably low as well. With all else working properly, that's really all that's left.

    Is this media new to you? Have you tried a media you have used previously?

    Once in a while, I have come across one roll of material here and there, that has a layer of dust on it, thru the entire roll.
    So Jim Hancock is on the right track, imho.
