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...

As regarding print speed. Based on my test of 7 december the LG-640 is about 2.17 as slow compared to our XR-640. It would have taken our XR-640 6 hours to do this work (44m2, 34 meters) the LG-640 took 13 hours. Due to 2 "problems" you will constantly be using overprint (which drops the speed...

I assume you mean Roland MG-640. From what I understand is the MG-640 the old model with the old heads and the LG-640 the new model with the new heads. Btw Roland clearly states in its marketing, see below, that the LG should use less ink and create less waste, as also said by the dealer, but...

According to Roland themselves the "running costs" or the maintenance consumption per day of the Roland LG-640 is 5.7 to 7.6 times higher compared to the Roland MG-640. See below.

Correct during these 26 hours. Measured from the drain bottle, from an empty drain bottle to 370ml in these 26 hours. This is all normal behaviour according to Roland, because they what to be cautious regarding the new type of heads.

Did another test last thursday. 44m2 of print files (took about 13 hours). Versaworks said it needed 253ml (41%) of ink. After printing the drain bottle contained 370ml (59%) of ink/liquids (during a 26 hour period). :( Completely unacceptable. Machine is going back to the dealer. Today did...

I do not see any "input profiles" under the "Quality Settings" tab. Do you mean Color Management Preset? "Sign&Display"
