RS-640 blurred printing
Hi all, im having problems printing with my rs-640, im using 3rd party inks from my autorized roland dealer, my roland is printing "blurred" colors when mixing inks, i think the problem is the cyan, ive tried all, changed wipers,dampers and captops, ive changed pump lines, set the heater temp to maximum, cleaned heads with swabs, adjusted bidir, vertical and feeding settings and im still having the same problem, im posting pictures asking for your help, thanks 😀

Try cleaning the encoder strip, it gets dirty and causes blurring. We had same problem on sc540 and worked fine after a clean.

are they bitmaps you are printing or is it the photo of the print that has all the compression on.

im printing vectors from illustrator and the fill test from service mode, the photos i took where compressed let me upload some without compression

test print looks just about ok other prints look like poor ink poor profile or poor media. or any combination of
check with a temp gauge that the heaters are up to the temp they say they are.

Ive always used same inks, media (banner and vinyl) and profile and never got that issue, ive always keep updated my versaworks maybe in one update profiles got changed, im gonna check for correct temp and heaters and i hope y reply with good news, thanks for the help

Have you updated the firmware on the printer?

i would replace the encoder strip before I replaced the heads!

cleaned again encoder, ive changed color managment from "density control only" to "pre-press us" and reduced cyan saturation to -4, almost all combinations of colors seems ok, im having problems only when using red with black outlines and viceversa.

nothing wrong with the printer… just bleeding ink…
normally caused by low-heat or misalignment but as u got a RS u have 1 head with all colours in line all the time, so i cant say it is that.
as Chris said, more profile / heat / media sadly

Mario,
What inks are you using? If you have the EcoSol Max, the profiles within VersaWorks should work fine.
Their appears to be a lot of deflection in the nozzels in the early images. That can indicate possible problem with heads.
If you changed to 3rd party ink, when did you change and how long after change did this start to happen?

3rd party inks, ive used them over 2 years and the problem appeared like a month ago

Service mode prints are perfect. Look at your profiles and how clean your media is. One of your first photos, my first thought was ‘dirty’ media, looked as though their were finger smudges on it.
Not the whole answer, I know. Sorry. -

Not the whole answer, I know. Sorry.Can u give a tip for selecting the best profile? Im having a very hard time trying to find one, ive read a lot but i still dont understand well :s

I have a Versacamm, and with vinyl use the MD5 profile (Metamark) for all. I was told by my service engineer that this profile seems to work best on any vinyl, and he is right, it does.

I use the MD5 profile for printing posters. The come off the machine dry enough to use the take up.

I’m not a user of this particular machine, but I find with my own machine (Cadet) I get similar "blurring" of colours when printing black onto red if I print at 360dpi. Changing to a different profile and printing at 720dpi fixes the problem for me – but the print takes longer.

Thanks all for your replys 😀

Um, no, I am using ‘sign & display’ – from memory, at home now so can’t check until morning. I was using ‘per-press US’, and changed to the other on service techs advice. Never failed me since, my print quality is great.

We have the Versacamm VP540 and have been having the same problems. There is a scatter of droplets around the text in all colours – we have been doing about 4000 small labels on gloss vinyl adhesive and then cutting the outline.
After techie call out for failure of magenta colour we noticed we had problems with the black. 2 weeks ago.. (I was able to part recover the head on my own)
we do not use the MD5 profile- will look for this and we use pre press US or EU profiles. temps look OK but not tested with other device
We have had Inktec Korean stuff and I conclude it is giving problems after 2 years or so. Suppliers will not stand by the inks.
Major improvement after going into bidrectional test mode, down into detailed tests
gives 4 charts with 4 colours. Then we reset the heads which neede quite large movements and different in every colour.Tom advice at Roland
The nozzle test show quite some deflection on the black head. Can we remove this and clear the dried ink is the next step.
O we had to do the labels at 1080 by 1080 to get the job out. 🙄
