How much more ink does a 12 pass use than a 4 pass?

I'm using the Epson s80600 with Onyx. We are printing a vehicle wrap that is basically a solid color (slight gradient throughout) and I'm worried about banding as we had some to start. I got that sorted out and suggested we run it on a higher pass. I used 4 vs 12 as an example. Now we aren't sure if that will use up an unreasonable amount of ink or if it even affects it at all, can't seem to find a clear answer.

Thanks guys :)

If the proper profiles are used, the printer should use no more ink. Profiles are mode-specific. If the proper profiles are not used, the printer will apply more or less ink making the print lighter or darker and thus not match from one mode to another. Prints from different modes should match closely within reason.

Technically it should be exactly the same. Say your profile is 720 x 720 and you go from 4 to 12 pass. They both print 720 x 720 but they just divide it into 4 and 12 passes respectively. Higher passes make it so banding is less apparent at the cost of speed. I usually prefer to make sure the printer is properly aligned and print at the lowest pass possible rather than up pass count to compensate.

I believe Epson Dashboard will tell you the ink calculations, and I think Onyx also has a feature for this. We don't use either here though.

REALLY?
i would have thought more ink would be used. one of my employees, who prints more than i do, insists we need to outgas longer with more passes, because of increased ink usage.
i know we can convince ourselves that something is true

Recently, I had an expert working on our flatbed. I asked him if the amounts were any different, cause they certainly felt different. Nope, not at all and he went into this explanation. After a while I just said, Okay, Okay because he has a very very heavy indian accent and it was giving me headache.

A single channel on a DX7 print head has 180 nozzles. A single pass on that head achieves a resolution of 180x180. 2 pass 360x360, 4 pass 720x720. So the head naturally prints 720 in 4 passes. When you up it to 8 pass and keep the 720 resolution, in order to keep it at 720 the head fires fewer nozzles per pass to compensate. If it continued to print at a 180 dot density for 8 passes, you would end up with a resolution of 1440 but you don't because the head compensates.

Dot size, the amount of ink in each drop, and dot placement density, resolution, is what goes into the ink use calculation.

Higher passes uses smaller ink droplets. Each pass isn't as dense as when using larger ink droplets.
Lower passes = More grainy prints
Higher passes = Less grainy prints.

Ink should be about the same.
Unless your more passes is maxing out on how much ink the printheads can laydown, that will ultimately end up in less ink usage.

For example, our Colorado 1650, i can print top speed, 1 pass. But the print isn't dense, so it'll use less ink as it cannot lay down enough in the single pass.

The difference between 4 pass to 12 pass (with ALL other settings remaining the same) should have a marked difference in density, with 12 pass being much higher output.

If instead you’re selecting a family - where variables like drop size, dither, ink limits, linearization, profiling etc is changing with the # pass selection, then perhaps not so much noticeable difference in density, because you’re choosing a compatible preset.

Where can this be useful? If the printer is calibrated at 4 pass, and ink limits on any channel is topped out, then you may be able achieve more gamut if the media can handle it at higher passes with custom settings/custom profiling.

Hey hey.

Just had a UCJV300-160 (LCLMWW) installed and the canned profiles / color matching just isn’t cutting it for raster photographic images. My 2009 Roland LEC-300A with its canned settings absolutely blows this thing away in just about every possible way can to can. Is this something you can help me solve? I’d rather not have to run my POD and Wholesale on two separate machines.

Compare the prints to one another and also from the installation confirmation prints the installer made for your approval before signing-off the install.

I’ll run these when I can.

I don’t run a traditional material, which means there are no profiles available for my situation, so we only ran canned profiles and color matching tweaks to get where we could get. The installer was not versed in profile manipulation and the various things we tried could not yield a sellable universal profile. I am in the print on demand marketplace, so I’m printing everything. Solid colors next to blurry pictures of a cat next to a pictures of a girlfriend next to a skyline. My Roland with its canned profile (EUV-2 ink - Version 2 generic media type - Sign & Display color management - 360x720 high speed pass), no curves or other settings altered - load and go outputs my various good and bad prints perfect and sellable 99% of the time. Anything I do not like about something I can catch and alter in photoshop before it ever makes it to Versaworks. With rasterlink, it seems like it’s a one does it a okay for one thing, one does it okay for another, but nothing feels remotely universal. No print quality issues. Alignment is great, calibrations are great. Test prints were nice as well. But when we got to real world, it was all down hill.

You'll need to invest in time and tools to either make your own calibrations and ICC profiles or call in someone to handle that for you. That's a key part of color management, to match printers to one another within reason.

Scott at Onsight or Mike at Correct Color are two good choices if they're available.

Post pictures of the evaluation prints if you get a chance.
