Re: sawtooth measurements in scan mode
#problems
Hey Chris,
Please attach the measurement data and I can see what is going on. Please include spectral values as well as the normal lab values too. An MXF file format is fine (this has spectral data).
Most likely there is some extra measurement somewhere . . . like it’s measure a combo of the last columns + paper white . . .
Also PPEv2 does not work with 31x9. It was on my list to update that in PPEv2 before getting canned . . . so most likely never will work with 31x9 . . .
Warmest, -Walker

I get results as expected when taking measurements in spot mode, as so - this is a spot measurement of a 51-step test chart printed on paper using a curve that I have previously linearised and ink limited for that paper to as ‘perfect’ as I could get it, so it is a good reference: <IMG_2365.jpg>

But when I take measurements of the exact same test chart print using scan mode, it looks as so: <IMG_2364.jpg>

I have left off any smoothing at all just to show the full extent of the difference.
I have checked the sample ID, position and sample name of each measurement in the saved measurements .txt files and can see that i1Profiler looks to be compiling the measurements in the proper order just fine. Has anyone experienced sawtooth measurements with an i1Pro 2 or ES-2000? Is it dodgy hardware? Or is it firmware related? If it is to do with it being an ES-2000 then how come spot measuring seems fine? I get the same outcome whether measuring a 51 step chart or a 129 step chart. I have tried with the 21x16 and 31x9 charts but - another weirdness - I cannot seem to get past measuring the first line of those charts, I just get told by i1Profiler of a measurement error and that I need to try slower (I am being very slow and precise). Maybe that’s something to do with the .pwxf files for those charts though?!
Any thoughts appreciated.

Re: Need help with separate Mac for printing DN only
Hi Jess,
First let me say that I am not a commercial fine art printing studio only a single person artist. So my needs, and solutions, are very specific, and in some ways similar to your questions.
Since I print with the piezography solution (inks, software, workflow) I also wanted to keep that system disconnected from the Internet. So I repurposed an old iMac, running Catalina, connected to my Epson P6000. I use the printer for making digital negatives (primarily Pt./Pd. and gum/cyano over), polymer plates (for direct to plate gravure) and a little inkjet printing (proofing and final prints). The iMac only has PrintTool and the QTR tools (the bare minimum for printing - and nothing else). No editing is done here. Separately I have a MacStudio fully configured (H/W and S/W) for image libraries, editing. etc.. I use a USB drive to shuttle images and install .dmg files (PrintTool, QTR..) over to the iMac. The only thing to always double check after installing the applications is that they have full R/W privileges (but this is an easy check).
My suggestion is to repurpose your MacBook Pro connected to your 3880 via USB; and, of course, not connected to the Internet so no unwanted or unexpected Epson updates or “upgrades". Not sure what version of OS you are currently running but if it is working now for your printing needs then I would leave it alone. Separately invest in the new Mac mini M4 with one of the third party port extenders that matches the fit, finish, and form factor of the Mac mini. Load it up with as much memory as you can; with all your creative (PS, LR, etc.) and QCDN software etc.; and a cohesive 3-tier backup strategy.
Lastly, IMHO, the 3880 was one of the last, best 17” printers Epson made that would allow user control and 3rd party inks (without major hassle). While the older P800 and new 900 are very, very good I would keep that 3880 for as long as it still works for you!
Let me know if you have any specific questions.
Michael

I use Print Tool, QCDN/QTR, Photoshop, Lightroom, FYI.

Re: Need help with separate Mac for printing DN only
I'm trying to figure out why you want to disable the internet on this, and which version of OS X you want to use. I probably am misunderstanding your needs or plan.? But if I were setting up a print server, I'd get an older machine that ran the version of OS X I preferred (perhaps a version before all the problems started cropping up with Presets, maybe Monterey? ). Probably a used Mac Mini. Turn off all automatic updates for OS and the printer.? I'd think getting an M4 would lock you into Sequoia or later - perhaps that's not a problem for you?
Then there are several ways to get things to the printer: file sharing either from or to the server, or printer sharing, or Air Drop, depending on your needs.

Multiple Issues Setting Up DTP with Epson P900
Each day seems to be different when it comes to starting out printing on polymer plates. Yesterday went fairly well, but today has been incredibly difficult. - When the P900 asks for what type of paper to front load, I choose posterboard and then it asks what type of photo paper. I've chosen matte and that seems okay. Any advice here?
- Yesterday, I was able to print on my polymer plate that was centered in a carrier that was 13" x 19" without issue. Now, the printer is printing on the entire carrier (see image #1), but still printing the test image on the plate as expected. I'm using Print Tool. Typically, there are no problems using this software. Any ideas what's going on here?
- There are also lines occurring?in the test image that appear on the printed image. How do I remedy this?
Thank you. I truly appreciate any help anyone can provide. I'm so new to this, I don't think I'm searching the group well enough to find the answers I need.

Re: OS Sequoia and Epson P700 - No longer supported by Epson?
Thanks for the reminder. I actually did that with the P9570 this week, but it did not occur to me to do the same for the 700. It’s that time in the semester, when logic and reason are replaced with frenzy.
Thanks again!

Re: Can not change the drying time on my Epson 7800

It's not how I understood this value. I think I tried with a value of 1s. I will give a try with an higher time

Re: Can not change the drying time on my Epson 7800
could it be that your increased drying time needs to be longer? When the increased drying time is less than what it takes to make one pass, you will not see any difference, as far as I know

I need to increase the drying time between each pass for a specific projet that I print on a Stylus Pro 7800.

It is the case when I print with QTR. I also tried with the Epson driver, both on the printer panel or in the driver setting, increasing the drying time has no effect.

Re: Kirkland paper alternatives?
I give up. Let’s just stop. Kang-Wei Hsu has a style of writing that I find needlessly abrasive.?
Perhaps I’m just in the wrong user group, although I have used QTR for years, and printed B&W on silver papers since the early 70’s.
