Roland Intelligent Pass Control (RIPC) Technology

it basically makes another pass to join the other passes so where you had 4, 8 & 16 pass it now becomes 5, 9 etc it basically migrates one pass to the next. This is written in to the profile so will only come on if you are using a profile with that in. How are you finding the Versa Art?

Thanks Kev. So I have to ask my dealer for new profiles with RIPC "in them". Interesting. I wonder if one really "see" the difference when printing with this RIPC and without?

I love the VersaArt. Just my observation here (rightly or wrongly): It having just 4 heads (colors) (CMYK) makes it better in print quality than our Soljet with 6 heads (colors). Sure, the Soljet prints much faster but it (Soljet) was set-up here so that we only use 4 colors (CMYK) and no Lt.Cyan and no light Magenta either which are not available in third party inks. As such, the print quality of the Soljet are dull or soft and comes out much lighter. The VersaArt on the other hand produces superb rsults, vibrant colors all throughout. It could be different for the other Soljets operated by other people off course.

I just need to know how to use the RIPC feature so that I’ll have the option to print at the best possible mode when we want them.

i didn’t get that… my jv3 builds up the pass until it is solid/correct, so your saying another pass to fill in some gaps? confused

was you not listening when we was at Roland, although might have been when Rob was wrecking the show room. From what i understand is, each pass touches but a blending pass joins them believe its more for high speed low ink situations. It just stops you seeing a banding line.

Dave wasn’t there Kevin……….

I think you are correct though it runs a filler pass which is claimed to eliminate banding.certainly good good in the showroom.

Hi John
after i typed it i thought was he or wasn’t he, i think it was cause i met him at Sign UK. Hope alls well with you

Kev

[Jason Xuereb]

Yup its called +Pass in the rip. That’s different to WPass which is on your older machines in Versaworks.

[Byron Villegas]

Mmm, "+pass". Thanks Jason. I’ll check out our Versaworks when I get to the shop today. So, basically, you can turn RIPC ON/OFF by using/not using the "+pass" mode?

haha… it was The Sign Show Kev and wasn’t at Bristol, bad timing for me considering I was only 100 miles away.

Anyway, im still curious to this filler pass, sounds dodgy! lol
If I recall, Roland did spend a lot of time but the headline to me was "The prevented samples being taking away", so you can see which bit I remember from the write up

[Jason Xuereb]

Yes Byron that’s right.

It’s under mode I just checked. Its usually only for the quicker speed settings. The higher quality settings don’t have it and don’t probably need it.

[John Thomson]

It was only samples from the 3d machine that seemed to be an issue…..

Thanks for that. Do you use it often? Will it really eliminate banding? Could it be possible to be able to have RIPC on our older Versacamms? Just a firmware upgrade maybe, and then use the latest Versaworks 3?

I also wonder how it compares to Mutoh’s "wave printing" technology.

Thats an interesting explanation Kevin.

The way it was explained to me was that it prints a scattered pattern instead of a block pattern which produces the banding.

Similar to the Mutoh wave pattern.

Having seen the results of both prints at a show, the banding was eliminated by both situations. That said though, its not until its in a real life situation that you can test it.

I get very little banding on my machines until the heads start to ‘go off’ then it becomes obvious.

I’d like to see a machine printing that has older heads to see if banding becomes an issue then. I’m guessing not, but seeing is believing as they say…

[Kevin Flowers]

Hi Shane
its a extra pass that blends the other pass quite probably as a controlled scatter pattern, the Mutoh as far as i know actually does what it says a lays its passes in a wave pattern so no straight lines. Both are just ways to mask that the machine prints a linear picture. Yes you can get banding with it i have metres of test files from the Versa Art printed from my files on to a specified media. Roland run the tests at different speeds, profiles etc to see what the machine could do & some banding is present why they sorted things out. It still goes down to the operator running the machine & knowing the machine, media and how the ink copes with certain colours. I run a Soljet 2 at the moment on 3rd party inks & i have got to know its limitations in some areas of colour and what speed, quality etc i can get with out banding etc. What most seem to forget that its not just the machines that can cause the problems and that the environment that these machines are operated in can cause a load of the faults that they blame the machine for. Clogged heads & bad printing can be as simple as the machine as sat in a cold room overnight & the ink as thickened. Its ok to think all is well when you are working & the temperature is at 20c but these machines need to be kept in that environment 24hrs a day for them to work at there best. So really these additional measures are just things the manufacture is incorporating to make operator error less of a problem.
Just my opinion

Hey Byron,

Its not available on my older versacamm and I’m using Versaworks 3 to drive both printers from the same computer.

I find that if your feed calibration is set right I get no banding anyways. I don’t really print at super high speeds anyways. Most of my work is standard or high quality. I don’t really use high speed settings.
