Re: P900 and P908 Questions

 

Thank you, Roy,
You are likely right about MK. I remember copying some .qidf files from P908 to P900 folders, and may have forgotten how I sent the 51 step files to which printer in Win GUI. I will check when I get home.
?
And ... it is great to know that I can create the .quad files on a Mac and copy them onto the Win folders and get control over full set of 10 inks. I used to something like this on an old 4000, where I had switched out one ink to 3d party violet ink. I probably have .qidf and .quad files still on my computer, along with Lab values that will guide me on choosing the right limits and densities for the 70-100% patches for the eggplant look. I believe I just copy K to drive the V, with small (2 or so) ink limits.

I’m also curious in everyone’s experience which MacOS they have had the best luck with QTR, QCDN, PrintTool, and Epson 3880. ?TIA!

Re: black only!

 

thank you all for your help!!
i forgot to mention I'm doing photogravure on polymer plate that is the rason I need only matt black!
I did the switch of all the ink for some cleaning liquid instead ( exept for the matt black) and all is working fine so it will be much cheaper now to run this printer!! only 50$ (canadian) for 1 litre of cleaning liquid I should be able to refill 3 time every color !! for me it's a 650$ saving..happy hope this help any one !
?
thank you!!

Re: P900 and P908 Questions

 

Hi Shilesh

I'm not really convinced you are getting MK but you'll see soon enough.
Anyway the main thing is yes you can use the Mac and use all 10 inks.
Create the .quad files and move them over to Windows.
Make sure you are using 2.8.2 -- look at About and the version of quadtoprinter
Printing will work fine with the 10-ink .quad files. Don't try Curve Create or
the Show Curves with QTRgui. They will both crash.

P900 and P908 Questions

 

Hello All,
I am hoping to get some guidance on using P900 and P908 on Windows 11 using QTR GUI.
  • Using P900, I have been able to successfully create MK profiles using K, LK, LLK, M and LM?and K only (BO).
  • What is weird is that I used P900 (not P908) to accomplish this, using "matte ink" in drop down menu. This seems contradictory to release notes 2.8.2. I am getting densities in 1.5 to 1.65 on matte papers, so I am confident MK ink is being used.
  • I used the customary curves creation dialog in GUI to define inks, densities, and limits, followed by linearization. I am getting good results.
  • Ideally, I would like to utilize V ink in the deep shadows (70 - 100%) to create an "eggplant" hue in these areas. The hue will not be visually evident in the last 90 to 100%.
  • I understand V ink is not supported for Windows. But according to 2.8.2 Release Notes, I can create full 10 ink curves on a Mac. Can I use these curves on Win GUI? And they would utilize V ink?
  • I am not familiar (at all) using Mac, but I was able to get a retired MacBook Pro (2011 edition) from my niece which has El Capitan (10.11) OS. I figured out how to create and linearize curves in Mac OS (in my mind, not actually done yet). I was able to print the 10 ink calibration page just fine.
So, can this be done? Create curves/profiles on a clunker Mac, but install them in Win 11 and be able to utilize V? Thank you all.


Piezography Pro Inks- UV densities

 

Hello All,
Does anyone have UV densities (from a UV densitometer) of the Proinks @ 100% on via calibration mode.
thanks!

Re: p5370 quad files

 
Edited

Hi Chris
?
Glad to hear that you are finding the Epson P5370 a useful printer for use with OHP. My experience with this printer in its previous generations (ie. 4800, 4880 and 4900) is that it does not play well ?with thin OHP sheet film and I eventually used it only with roll film, with which it is very reliable.?

New (old) Mac

 

Yesterday I bought a 2015 MACbook for running QTR, Epson print driver, QCDN V3, and SpyderPrint. The laptop is running OS 13 (Mojave) and cost me $100 with charger. ?I am hoping this small investment will save me the wasted time and frustration caused by Apple updates and incompatibility issues. I will do all of the QTR curve creation functions on the MacBook, and I will process image files on my Mac Studio and transfer the files to the MacBook via file transfer for printing.


Re: black only!

 

Those colors were really bothering me. I believe light spill from work monitors were causing the color cast. Here are more realistic images.


Re: black only!

 

?
Good shadow separation. Trees with details, reflection on water under buildings. These block-up when printing with ABW using Epson Hot Press paper setting. This is not because ABW is incapable, rather because there is no ABW profile/setting for the Estrada paper. Linearizing ABW is easy enough. When printing this picture on actual Epson Hot Press paper, the details are just as perfectly rendered.


Re: black only!

 

These are unedited pictures from my cell phone.
1st picture is BO. "2880 Super" setting in QTR.
2nd picture is from My interpretation of "warmish" using K, LK, LLK, M, and LM inks, also using QTR and printed at "1440 Super setting" The warm tone is exaggerated in this cell phone picture.


Re: black only!

 


Re: black only!

 

But this old paper flakes a lot (now and also previously in 2006). So, I am looking for some coating solution because I have more than 100 sheets in 13x19 size left over from many years back.


Re: black only!

 

Hope this is not a duplicate post.
?
After many years of absence, I re-started black and white printing last week, particularly using QTR. I am well versed and experienced in creating QTR curves from scratch. Previously I used Epson 4000 for BO printing on some papers. Particularly I found was Moab Entrada Natural (from 2006/2007 timeframe) produced very good results on the 4000. I remember for the Epson 4000, BO printing on "gloss/luster" papers was never satisfactory. I now use Epson P900, and yesterday I printed and linearized BO on the P900 using QTR set at "2800 Super." The resulting print is gorgeous. The 3880 printer likely has "2880 Super" setting also. At arm's length, the highlight dots are not visible, the ramp is very smooth visually. I can separate tones in 2% increments from paper white to Dmax. In any event, the characteristic of BO that I find most appealing is the graceful way in which the highlights naturally go towards paper white (a and b) tones. If your picture has a white border, the print looks organic to the paper, and the overall tone does not seem to fight against paper white. If there is any interest, I will be glad to send my linearize measurements of L, a, and b from paper white to maximum black. The weird thing on the paper (again, left over from 2006ish timeframe), Dmax is only about 1.6, yet the visual appeal of the resulting print is as good as on Epson Exhibition Fiber (Dmax > 2.4).
?
Short answer. Yes it can be done with QTR. And The results can be gorgeous if you have the right paper match.


Re: Epson P900

 

I inserted the DTP curve in the wrong field!?
