Simply depends on how good you need your color to be. The vast majority of printers do not do their own profiling or have anyone do it for them.

Does the K only "grey" actually look neutral under either light source? If you're really on your color game, you can get CMY to adapt to a custom light source. Well....most light sources anyway.

if I remember right it was an EXE file that ran and the printer rebooted. Although come to think of it, it may have had an interface that gave some simple feedback. It was a simple process and solved the USB timeout problems I was having. But not the menu selections in service mode are different.

Is there no one that can help me do a simple bidirectional calibration on this printer? I can't believe that it is not obvious in the menus.

I updated the firmware to sort out USB timeout problems. It fixed the timeout, but the bidirectional is totally off an the menus are different. I can't find the place to print the pattern for the bidirectional adjustment. Can anyone help?

delta e C = chroma, L = lightness if the chroma delta e went up the back down, i'll wager your actual chroma value went up as you measured down the ramp. Kind of interesting that less ink can produce more saturation. Many folks find that apex of chroma and reestablish the reference on that...

You're spoiled already. Love it. My guess (I don't really know) is that the mappings have to do with spot color rendering.

sounds like you've got it I don't know the roland well enough to suggest specific head speeds. But the faster you go the more the dot will "splash" when it hit the media. At some point it no longer is very round on the media and becomes more tear-drop shaped. This will contribute to a rough and...

why use an icc at all? Good question. Simply put, the icc gives you color accuracy. Accurate reproduction of the color in your incoming digital file based on the LAB values of that color. This assumes the file's embedded profiles are respected as the input profiles for the printer's output...

As usual, Rooster is dead on. You don't have to match the warm grey thing perfectly. Only if you were striving to make things as perfect as possible without the icc. But, you'll have the icc to get the fine tune for most jobs. Again, don't use the icc only for jobs that are not color critical...

Bingo. What you're striving for is to have your linearization give you a warm grey ramp from the fixed CMY ramp. IOW, don't tweak the file to get results, tweak the linearization and/or ink restriction. Everything we're talking about happens PRIOR to the icc coming into play in any way. Set...

100% agree. But here are numerous upsides to achieving the warm grey balance, especially after linearization (before icc). You can output CMYK files without the ICC in play and get REALLY poppy color. Granted it will not be technically accurate. But for somethings, poppy is more important than...

Amen brother.

1440/32 pass....holy crap that's gotta be slow.

Depends on how lazy you are. To do it as best as it can be done, start from scratch each time since the ink restrictions are unique for each media/resolution.

Yes, you absolutely need a unique profile for each resolution. You can change the number of passes and head speed without effecting color. But resolution has a big impact on the way the ink goes down.

I found that I could just flip the worn strip. Seems to work well so far.

Anyone know the actual material of the rubber strip that goes under the cutting blade? My vendor wants $57 for what is likely a $6 part. Plus, I'd like to stock a few extra. It is 3/8 wide and 3/32 thick with an adhesive back on it. It's pretty firm. Any ideas or sources would be...

You are right the dot size is the same in both systems. 6 color and 4 color systems have the exact same gamut potential. What you gain with light inks is the fact that our eye can't see the printed dots as well when they are made with lighter color inks. This makes it appear to be higher...
