  • Black running into yellow on print help

    Hi
    Roland sp540v. Versaworks.
    Got a load of vinyl to print, consisiting of a lot of black lettering on a yellow background, artwork from customer. I have checked – the black is 100% and the yellow is 100%. The two colours are ajacent. However the black edges seem to be running into the yellow and forming an ugly edge.
    Whats going on? I have not had this problem before.
    Does anyone have any workarounds they can recommend?
    I will try to load a photo…

    Simon.

    Are you using a different profile or media to normal? My thoughts are the ink is not drying quick enough or is being laid down too heavily saturating the media. Are the heaters working properly?

    I would agree with Phil………heaters would be my first thought………looks like cold vinyl.

    Slow it down with more passes / go uni-directional to give each one half a chance to dry and put the heater temp up on the print & post heaters.

    Change dot size to small if it still persists.

    After that…I’ve put coloured vinyl through the printer before just printing the black when a specific shade was required…nothing to bleed into then.

    This is the only colour combination that I’ve had this happen to me on before also,
    I cured it by printing a thin stroke (0.15mm) on the text @ 25-50 % yellow, you don’t notice the stroke but the print creates a bridge between the two inks and stops the bleeding.
    Heat and slowing down the feed rate helps too, I’ve also done the solid colour vinyl option aswell

    Thanks guys….FIrst I tried it on high quality and it printed fine, but there is 70 meters to do and it is low cost stuff and I cant afford to tie up the printer for two days.
    Then I cranked up the heat to 48 degrees and hi speed, and that has taken care of the problem. There is still a TINY bit of seepage, but it is only visible on very close inspection and acceptable for this job.

    I would have said heaters too. You could still check try and make the black a single colour black rather than a 4 colour black (sometimes called UCR or under colour removal). I wouldn’t know how to do it in Versaworks though.
