It is a problem because one size does not fit all.

You really need to make your own profiles. When I first got the L25500 back when they were first released it became quickly apparent you could not threat latex inks like other inkjet inks. There is a certain sweet spot as far as ink density goes. Not enough ink and it looked washed out, too much...

Managing the split levels between regular and light inks? Tell me more. I this not a contone device or is HP allowing some kind of control over the light ink splits/curves on these new printers?

I think that has been well documented in this forum, and I don't remember having those color consistency problems with the L25500. If you call HP techs they will tell you the same thing. With the L300 series you don't really want to be using lc/lm inks at 10pass and lower. I have seen way to...

I still don't understand the use of only 1 light magenta / light blue printhead, when they know the color consistency problems that is caused when the printer is run fast. After being told that the optimizer printhead being too close to the other printheads was causing a problem, now they...

"1 light magenta / light blue" Printhead. My God, haven't they learned their lesson. Can't really tell if it is a Contone device or not. Maybe I missed something.

Probably not compatible, but you could try this. At 20pass, lowest heat highest airflow, if ink not dry then start raising heat 5 degrees at a time and raise Optimizer 5% at the same time. If ink is still not dry when it starts warping, then lower heat 5 degrees and add more inter-pass delay...

Let hope they fix the deficiencies of the 300's and are not f'un Contone printers.

In the Advanced option of your media setting do you have OMAS turned off?

Are you sure it is Onyx or the Printer/Media combination. What Printer? What Media? There are a lot of printers out there that are set by default to make feed adjustments based of what banding they might be detecting. This could potentially alter the the length of any print if this is not...

I would not trust any media setting with a obsolete flag unless you know it was created from the new media (at the top of the list) since the latest .12 firmware. If you are going to linearize with your RIP the flag should be "Recommended" 1st point. Just to clarify this again. At the top of...

Ignore this Color Monkey, he has no clue what he is talking about.

In Fiery XF in the Color Management tab set Color Optimization as Black as Inkjet Black. Set Manual Cleaning to at least cover the percentage of black in your grey. Also make sure you are using the APPE PDF Print Engine and not PS3. One other absolutely critical setting is your CMYK source...

Looks like pretty poor welds to me.

I am hoping HP sees the light and gives us an option to again to have a Latex printer that is not a contone device and have two lc/lm printheads. I guess giving us higher ink densities at 10 passes and lower would help a lot, but that would cause even more problem with having only one lc/lm...

Looks like you're loosing light magenta. How old are the lc/lm printheads or how much ink has been run through them? Other possibility is air in the lm line.

It is unfortunate that the use of two lc/lm printheads caused a problem being too close to the optimizer printhead. So your seeing the result of only using one lc/lm printhead. 10 pass and under will cause these problems if lc/lm is used. It is either ink starvation or lack of redundant...

Have you done a nozzle check?

A flatbed laminator is pretty limited to specific applications and not really designed for over-laminating with release liner over-laminates, especially from printer take-up roll to laminator take up roll. Why aren't you using your roll to roll for this?
