HP Latex 360 Fuzzy/Blurry/Overspray in spots

#1 jrhodus 3 years ago

Hello,

I need some help with a fuzzy/blurry line issue with my Latex 360's(Photo attached). I didn't have this issue with my L25500.

The fuzzy/blurry/overspray lines are only in certain areas which makes the problem even stranger.

I'm running Ergorsoft Posterprint - 12pass, 600x1200, 600x600 rasterization, 110% saturation

I've tried all combinations of high and low optimizer, airflow, interpass delay, heat, the color/small print optimizer on/off etc.. I've aligned and cleaned printheads.

I'm printing on a heat transfer media for apparel.

Need some help with this!

Thanks

Hi

Looks similar to an issue we had.

Check that in the menu settings for Image Quality Maintenance, that both Vertical Correction and Colour Correction of small text are both switched off, this sorted our problem.

Thanks for the response.

I've always had vertical correction off and I've tried with both color variation on and off and neither way solved the issue.

I've been told to add color bars down the sides of the prints and though this did help, it didn't completely solve the issue and it's not the solution I want as it wastes ink, media and interferes with my registration marks for contour cutting.

Hi! I've had the same issue, maybe you should down the saturation at 80 - 90 % . It works for me. I'm printing on Self Adhesive Ritrama RiJ45.

When some fuzzy/blurry/overspray lines appear in the job, I will recommend to do one of the things listed below in order to try to correct the issue:

1. Ensure that printhead aligment is correctly performed. The automatic printhead alignment is
recommended.
2. Use a render resolution of 600 dpi.
3. Add spit bars. It will keep the printhead fresh if it is not used during the swath.
4. Rotate the job 90 degrees. Depending on content, rotation will allow the maintenance of
constant image quality during the entire swath.
5. Print the text in vertical orientation (paper axis orientation). By doing that, the spray
generated while printing will be located between lines, not between letters, making the output
more readable.
6. Print in high quality mode. 10 pass printmode or higher.
7. For color text, turn ON the Color variation and text-line correction option. It can be found in
the printer frontpanel under Image-quality maintenance > Color variation and text-line
correction > On. This option also keeps the printhead fresh if it is not used during the swath.

If none of this tips work, I will recommend you to contact HP Support (thru your reseller).

@ferrer_leo Thanks for the response. I've tried lower saturation levels and the problem still occurs, but lighter.

@HP-MarcM I've tried all of these things and they haven't fixed the problem. I'm in contact with HP for more solutions. For now I'm using the colorbars to be able to move forward with profiling. Having problems there too so I'll start a new thread.

Thanks

Try following the steps for a manual PH alignment. I had a unit that did not look like it was aligning properly until I did the manual PH alignment and then auto alignments worked fine after that.

Cheers and Good Luck.

You need to call tech support and tell them about the issue. When I did, they told me they had a bad batch of magenta inks and that is what was causing it. I had the SAME exact issue you have. They replaced all 3 magenta heads and sent out new inks. They also sent out a tech to update the firmware with some new version. He did it off of a usb drive. After they did this, the magenta overspray issue went away. I bet this is what your problem is. No amount of cleaning or head alignments is going to solve your problem.

I have my printer paired up with a Summa cutter which uses 3mm square marks for registration. I too am having trouble fuzzy registration marks.Rotating will not help since the marks are square. The spit line works to a degree however, many times there is not room for an extra line. I just did a head alignment and only the black seemed to be guilty of fuzzing out. Still , this problem needs a solution.Tell me the engineers are working on it.(don't fib) Thanks

Hi Chimuka,

I will recommend you to download the new firmware as I've said in this other blog post:

Printheads go out with no warning.

Anyway, you can try to print thicker lines in order to correct this problem. If this doesn't solve your problem, and you are not able to add spit bars, I will like to ask you to contact your support representative.

Im having a similar issue with blurry areas in my print - large or small jobs. Anyone else experienced this issue before?

  • Print heads - good
  • did printhead alignment (auto)
  • fresh inks

happens on paper and vinyl most times
