I placed my preorder with B&H Photo in April when it was first announced. As of today, they still cannot tell me when they will have them in stock to ship to preorders.

Has anyone seen one of these in the wild?

Regards,
Bud James

......At this time, I'm sorely tempted to buy a RIP in order to explore custom ink channel ramps in more detail, and I'd be interested in hearing more about the ColorGate RIP in this regard from Gerd.  HP's Z9 driver leaves me wondering if a good RIP wouldn't squeeze more color gamut out of the Z9.  I'm also fascinated that the ColorGate RIP can open up the Z9's spectrophotometer capabilities, but a RIP is an expensive and typically unnecessary proposition for individual users like myself, and it's disappointing that HP management decided to dumb down the Z9 functionality so much compared to what individual users have with the Z3200. That said, I also wonder if a third party RIP can invoke HP's incredible "pixel control technology" or whether the RIP designers have to develop their own screening pattern. I don't see how it can get any better than what the Z9 offers with respect to dot placement and smoothness, and I worry it could be worse with a RIP.

cheers,
Mark

Colorgate does not change HP's pixel control technology. And does not use its own screening pattern for printers that work in RGB mode. With pure CMYK + spot color printers, the printing grid can then be determined depending on the printer type.

You query the respective device directly from Colorgate and get the performance features.



Cologate stores everything together in a MIM (Media-Ink-Metamode) file. So a file that describes the combination of properties of the printer and the paper.

Then you can profile.


Build custom targets, display deltas, identify measurement errors etc. etc. The measurement values ​​are saved as a CGAT text file. You can continue to use them.

Measurement is automated in M0 Spot Mode (each patch is approached individually).

For example
Patch fields standard


Patch fields scrambled


Colorgate queries the HPZ9 + via SNMP (Simple Network Management Protocol). That means Colorgate knows the firmware, the paper, the profiling etc. etc..... all these varibals can be individually printed as small text with the test image. This makes it easier to differentiate between test prints.

You can also use all common measuring heads such as e.g. X-Rite & Co. with Colorgate.

The profiling / color engine reminds me a lot of Colorlogic. I'm not sure if they are using Colorlogic technology, but it looks very similar.

The software can be tested free of charge - without any restrictions. They will send you a dongle with a test period of 14 or 30 days.

The first Z7 I bought was around £3,100. I saw the same model advertised recently by the same dealer at around £2,300.

Time usually sees large discounts.

Certainly but my point is that the price of introduction is much higher.

Cheers,
Bernard

Hello Soboyle hello Mark,

I have detailed my contribution with a few examples.

At the request of @Soboyle and Mark @MHMG from the LL contribution LINK, I will go into more detail about my previous problems with the Z9 + 44 ".

The HPZ9 + 44 "was delivered with the firmware JGR9_06_19_41.2.rfu.fmw. This is also the current firmware - both in Europe and in the USA. The firmware is from 11 Nov. 2019 and has a size of 1.6 GB current HP Utility has the version 6.0.9.4660 and is from 4 Jun 2020.

Own paper profile problem:
1. Own paper profile created with the setting stark (stark means heavy). Hahnemühle PhotoRag Pearl mehr Tinte (more ink) 320g


2. After loading the roll, selecting your own paper profile and density measurement, the profile is back to "normal"


When printing, there is head contact.



Manufacturer paper profile problem:
1. Upload manufacturer OMS File via HP-WEB Access


2. Confirmation from the printer


3. Confirmation by the web tool


The paper profile does not appear in any selection (the current one is not overwritten either) and can therefore not be used. So no solution to get the desired paper thickness.


Star wheel problem:
In the official firmware (JGR9_06_19_41.2.rfu.fmw) the position of the star wheel is not adjusted - regardless of what you set in the profile.
If you want to test the star wheel position in service mode, the test fails completely.


HP has provided me with a beta firmware JGR9_06_20_06.1.rfu.fmw. With this firmware, the star wheel position can be easily adjusted.
Here is the test in service mode for the star wheel position.


All other problems remain.

Firmware errors:
The HPZ9 + often has firmware errors. System errors are usually often unspecific and not documented. They depend on the respective firmware. There are notes in the service manual, but there are no precise ones.
Here are a few examples.




The errors usually occur with the HP Utiliy. So when I read and write access to the printer.
It looks like this on the computer:


My impression is that the firmware / software is not ready or was partly taken from the Z3200. If you e.g. a default ICC profile (not yet profiled) exported from the HPZ9 + and then looking at the TAG targ/text in the profile you will find that this has 864 patch fields and not 464 patch fields as after profiling.

Greetings Gerd

Thanks, Brian, will give that a go. Yes, paper is not brand new and has a bit of a curl; also my gap setting is not currently wide. Will do this and report back.
Both prints look like you have had head strikes on the paper, make sure there is no curl in the paper flatten first before printing, hopefully there is no damage to the print head, post a nozzle check print if you can.

Make sure the gap setting in set to wide.

Brian.

Thanks folks.

My wife took this photo while trekking in the northern most parts of Pakistan, in the Balistan region.
The Himalayas, The Karakoram and the Hindu Kush mountain ranges merge together not far from here. The borders of the PRC, India and Pakistan meet not far from here.
Security is tight in this region, as expected. But not unduly cumbersome for foreign travelers.
The PRC and Indian armed forces had an incident, reported widely, also not much far from here.

About 1400 kms via one the old silk roads from here down south lies the Khyber Pass and Afghanistan.
500 kms by propellor plane ( weather permitting ), lies the airport of Peshawar. The landing strip in these parts is about a hundred kms below where my wife took this photograph.
Lovely, Generous, hospitable people..and unbelievable and barely traveled landscapes.

Arguably, one could say raw, hard, powerful beauty of nature in front of one's eyes.

Stay well.
