Roland LG-640 print speed and Roland MG-640 print speed. Ink consumption of Roland LG-640 and Roland MG-640

And one more about the print speed of the Roland VG3-640. We run our XR-640 and VG3-640 at the same speed and quality about 6m a hours about 7.5 m2 a hour.

See print speed of the Roland VG3-640 in these pictures.

Here Peck V.6.2.3.

We haven't used our LG-640 since december. Never put the machine into production. It's in the hands of the lawyers. (Dealer doesn't even reply to emails (send to 5 people)).

It seems a lot of users are having blurry red/orange prints. Looks like a big problem. This machine is not close to production ready. After doing the print-profiles of our new VG3-640, I can match CMYK black and RGB black almost perfectly. Like with our XR-640. From a meter away you will not...

I will be doing a small Youtube video review of the machine, and comparing it to the XR and VG3. If you have any questions drop them in this thread.

Regarding the CMYK black you are incorrect. The CMYK black of our old XR-640 and new VG3-640 out of the box is pretty good. The Roland LG-640 CMYK black is brown. Only when you do a overprint (200%) is this close in saturation to a solvent black (Mimaki UV machines have a similar problem, see...

josephF Thanks! You also, ones a month, clean the glass in front of the LEDs on both sides with a alcohol wipe? Mine have largely got a bit of yellow "hue"on them from the yellow ink.

What exactly is broken/wrong with your LG, if I may ask? Are your 2 printhead that dirty after just one day of printing? As this would definitely give problems in the long run. I am experiencing issues with the printer saying "no inkt." The solution (from Roland) is to switch the back plastic...

1. We use a thermal Flir camera before we apply wall covering wallstickers/decals/cover etc. to spot issues, like water leakage in walls (this will give cold spots), etc. 2. Many paint nowadays, have water/dirt repelling characteristics. These paints are ever more common in the Netherlands...

Well speak of the devil. I inserted a red cassette and it bend the entire needle (the 6th cassette I replaced in this machine) (I have been swapping 3-4 cassettes a week for about 25 years, never had 1 issue or drop of ink). The printer needed a new needle. This was done by a different Roland...

Can you be more specific. What issues are Roland having? Thanks in advance.

I have started a lawsuit against the Dealer, here in the Netherlands. As they do not want to take the machine back, or exchange it for a VG3. Both Roland and the Dealer have seen multiple CoPeck files and they have never disputed my findings or the level of ink wastage. They have simply been...
