Wonder if changes will be enough (like the last firmware) to have to go beyound just calibration and have to re-profile. Well I haven't re-profiled much media after the last firmware update yet so if I need to re-profile, it won't be that big a thing. I will just have to check it good before I...

That is what I figured. The prevailing theory is to let these printers on when not in use, but when I had a L25500 I had nothing but trouble doing that. When I left it run overnight I would come in in the morning and find it powered up, sometime with the fans fired up and sometimes with a error...

Did you shut it off or leave it on during that time?

So even with the new firmware HP still has not given us more ink density with 8 and 6 pass? On 6 pass are using just CMYK and setting the OP as low as possible?

I would have turned the machine off. When I had a L25500 it would do strange things when left on and not printed for a couple days at a time. So I started turning it off every night and never had any more problems with things like that with it.

So re-calibration is not enough?

Sounds like your missing link is still an ink limit/linearization/profile of your printer/media combination.

A proper color managed workflow. The most important part is to create an ink limit/linearization/profile for maximum color gamut of your printer/media combination. If that doesn't get you there then read in the lab values from a pantone book spot color with your spectro and update those values...

Sounds like you trying to use a PVC film.

That is absolutely hilarious.:U Rock:

One word of warning though. You input profile has to match your print file. If you get jobs like I do (that no matter how much I harp on them) where the designer can't be bothered to assign the profile to the pdf and the original black was 100% only in WebCoated SWOP but you guess GRACol you now...

.030 runs fine in the L360. I run that all the time.

All you need to do is compare the onboard calibration black with the black your printing to see if the color managed black looks watered down.

Discovered it was a setting on the RIP that was preventing pure black from printing. So with CM enabled and Black as inkjet black enabled I ran the same black patches again. Pure inkjet black from 100K only still looks better than any color managed rich black combination.

So far thought out the RIP calibration process I have had pure blacks. Just need to make a profile now and setting 0-0-0-100 with Black as inkjet turned on should print the same pure black as the calibration targets.

If the job has a rich black build then it will use the CM of the RIP to print. But with latex I would not call the as rich a black as pure inkjet black. Never could get rich black builds to print as nice a black as pure inkjet black.

You seemed to be missing my point. The black on the onboard calibration target is black only. That is what I want when I send a job with 0-0-0-100 build and set the RIP (Pure Hue or Black as inkjet black) which is how I printed blacks with the L25000. Much better black that any rich black build...

The onboard color calibration I was referring to. But now that you mention how does the RIP calibration black compare to the onboard calibration black. I need to check that on my end with the RIP calibration which I no longer use but maybe that is the missing part of the puzzle.

No I assign Adobe RGB which is what the PDF was that was generated and the conversion went from Adobe RGB to the output profile.

But does your black printed from the RIP with Pure Hue enabled come anywhere close to the full black on the calibration target? In other words 0-0-0-100 with Pure Hue enabled match the full black in the calibration target. HP Engineer says it should and it did on the L25500 and L260 but I can't...
