"starter profiles" for digital negatives

"starter profiles" for digital negatives

2012-06-22 by John

I'm just getting started and trying to find a source for QTR profiles used for creating digital negatives. In particular, I want to tackle silver gelatin first. Any assistance will be greatly appreciated.

Sorry if I didn't provide enough detail, but I'm using a MAC, Espon 3880 UC, and Ilford Multigrade Fiber glossy. Thanks

While it might take you a bit longer compared to starting with someone else's profile...may I recommend learning how to make profiles from scratch? It's a bit more difficult with a Mac, because you have to wrestle with the syntax of the file compared to the GUI in Win.

I make this recommendation for a couple of reasons..1) you'll learn a lot about QTR and making digital negatives in the process, and 2) everyone has a different way of building profiles, and what another user did may not make sense to you, even if it works.

Additionally, another user's light source, chemistry, development method, etc. make the profile essentially unique to that process (IMO), so you'll likely have to do a lot of tweaking anyway.

The simplest curve to make uses only PK ink, and from that you can get used to using the ink limiting and curve controls, as well as linearization. Then you can tackle gray partitioning when you add the LK and LLK inks.

Keep in mind that since multigrade B&W papers have some color sensitivity, be careful in applying colored inks...you'll have to carefully balance M and Y inks and apply them in tandem if you want to use them, otherwise you'll be activating different emulsions depending on where the M and Y inks get laid down, kind of like printing a C41 negative on B&W multigrade paper.

With all that being said, if you'd prefer to use someone else's profile as a starting point, I've got a couple of profiles for B&W paper that aren't totally fleshed-out (not linearized), but should get you started. Contact me off-list and I'll send them to you.

Good luck...

Is there a program that allows a simulation of windows well enough to run
the QTR Windows GUI?  I'm totally unfamiliar with how Mac people make their
profiles, but I take it from the discussions that it is less user friendly
for those of us with very limited computer skills.

Greg,
Points well taken. Regarding light source, I have heard that using low contrast filtration with digital negatives on Ag/gelatin seems to work best. Any thoughts on this?

Paul,
No computer expert myself, but when QTR is installed on a MAC, the printing interface is in Photoshop. The curves, which are called .quad files, are built from a text file which one manually enters the ink density, limits, etc. Also, you have to manually provide a path to the gray curve used to linearize the midtones. QRT provides tool to show the a graph of the ink and generate a quad file from the text file. It's not too bad. Printing while in Photoshop is a nice feature.

I'm on a PC myself, but I believe most people use "Parallels" (a virtual machine software), but I suppose VirtualBox or something else like it would work as well. I find the GUI useful for curve editing (and graphing)...the GUI creates both the QUAD and QIDF files. You would probably want to print through the Mac native QTR. A little round-about, but I prefer the visual interface for curve editing.

Re: "starter profiles" for digital negatives

I didn't investigate this...I simply used un-filtered white light.

Conceptually, it would make sense to use a lower-contrast filtration. Even when using the gray inks, there's still areas of ink surrounded by areas of clear film. I would think a hard filtration would emphasize this and a soft filtration would minimize it.

If that's the case, you could make yourself a Grade 0 profile and a Grade 5 profile for different visual effects in the print, while the overall tonal distributions would remain unchanged.

I may conduct that experiment myself sometime in the future (whenever that is.)

I tried this. 
However, there is also a problem. 
It is the printing quality of QuadToneRIP.
It seems that processing of micro weaving is not good.

There are some resources out there for persons just getting into the QTR-digigneg world. I highly recommend checking out Ron Reeder's site and purchasing his ebook on the subject. ( http://www.ronreeder.com ) . I also have a free and fairly detailed .pdf file on my site that you are more than welcome to download and peruse : ( http://www.clayharmon.com/download/downloads/QTR.pdf ).

I use a Mac, but run the QTRgui in a windows virtual machine (VMware Fusion) for designing my curves. 

Also check out http://www.dpug.org for many threads relating to digital negative creation.

Clay,
Thanks for the links. I started with Ron's website and have his book. Appreciate the guide from your website.
This is very helpful.

Re: "starter profiles" for digital negatives

2012-06-23 by gmikol

I just want to note that the profile included below does not work properly...QTRgui throws an error because the linearization data is in the wrong order (for L* data, it must be from highest to lowest values, i.e. paper white to dmax).

One must be careful when using the LINEARIZATION command with digital negatives. The measurement data has to be manipulated in order for QTR to use it properly. There is no way (that I have found) that using the straight measurement data will yield a linearized negative.

Mr Greg

Are you using Windows QTR?
It is correspondence of only Mac QTR (Ver,2.72). 
I have fixed patch for Win QTR. It was given by Roy. 
Please download. And please overwrite. 

http://www.digital-negatives.jp/TEST/qdensity.zip

About Digital-Negatives Linearization

Step1:
Measurement the density of a print. 

Step2:
Please input in an order from a small numerical value. 
Example
LINEARIZE="8 9 12 ..."

Ron said that WinQTR Digital-Nega Linearization was also corrected by next program update.


Please try this.

Re: [QuadtoneRIP] Re: "starter profiles" for digital negatives

I believe I got that file from Roy some time ago and also have upgraded to 2.7.2 but when I last pasted a set of L* measurements into the linearisation tab I still was getting an error message from viewing the ink curves. Anyway, the workaround is very simple, normalise them to % figures and turn them into negative values using Ron Reeders instructions for scanner data, then use them as a greycurve.


Oneday it will all work, I am shure, and that will be fantastic because there is no simpler way of making digital negatives. Print a wedge, read with i1 and colour port, dump file on linearisation tab. Done.

Thanks
David

Mr Greg

Are you using Windows QTR?
It is correspondence of only Mac QTR (Ver,2.72). 
I have fixed patch for Win QTR. It was given by Roy. 
Please download. And please overwrite. 

http://www.digital-negatives.jp/TEST/qdensity.zip

About Digital-Negatives Linearization

Step1:
Measurement the density of a print. 

Step2:
Please input in an order from a small numerical value. 
Example
LINEARIZE="8 9 12 ..."

Ron said that WinQTR Digital-Nega Linearization was also corrected by next program update.

Please try this.

I just tested the file that Kentaro Kumagai linked to, and it works as expected on QTR 2.7.2.

Mr. Kumagai...Thank you for providing this link...it eliminates one step in processing digital negative curves. I look forward to Roy making a general release.

David...you should try this again. It really does work. And the workaround is simpler than you describe...you can transform the measured L* data similar to how Ron describes, and paste it into QTR, and it works. That's what I had been doing.

Re: [QuadtoneRIP] Re: "starter profiles" for digital negatives

2012-06-24 by 228044881 228044881

I am  still getting the same error message when I click the "show curve" tab. Invalid coordinates at quadprofile.pl line 41, Curve creation failed. I have reinstalled QTR, tried and then also replaced the qdensity file with the supplied file. Still same error.

A completely different inkjet printer, inkset and profiling method but 
possibly interesting to broaden the scope of this thread, the more when 
the mask's color is discussed:

I don't know if this is the issue, but I think I had a similar error one
time... fixed it by creating and saving the curve while Photoshop mode was
set to grayscale.

David--

I believe the "GRAY_CURVE" command is limited to 16 pairs of numbers. It appears you have 20. I'm also not sure you're calculating the "GRAY_CURVE" values correctly. What is your actual measured data?

With the modified qdensity file, why not just put the measured values into the LINEARIZE field?

Because it dosent work. Theese numbers are entere into the windows interface, you can put lots of numbers there if you want, but there is a limit. This is a curve for K, and  it is copied to the other inks, not a grey curve.

Re: "starter profiles" for digital negatives

I misread your profile...I see now that you're using a specific curve for black ink.

I can't, however, replicate your error. I loaded your profile into QTR (win) and it did not have any problems plotting the curve.

Sorry I can't be more helpful...

Mr Greg

"GRAY_CURVE" command 20 pairs is No Problem.
I am using A satisfactorily. 

My "Ron Reeder Platinum print profile" mod (21 steps)
http://www.digital-negatives.jp/download.html#ron

The limit of 16 pairs is "Photoshop curve (.acv file)".

Mr Daved

I checked your profile. 
And this is no problem. 

Digital-Negatives Linearize also worked well.

Mr Daved

I checked your profile. 
And this is no problem. 

Digital-Negatives Linearize also worked well.

Re: "starter profiles" for digital negatives

If you are able to dedicate the printer to digital negatives I would recommend Jon Cone's Digital Negative Methodology #3. I have installed this inkset on my Epson 3800 and am getting negatives for carbon printing that are much freer of artifacts than I was ever able to get with the Epson K3 ink set.

Very interesting and appealing, I will investigate but not sure I can totally dedicate my 3800 to digital negatives.

Re: "starter profiles" for digital negatives

Actually you can use the 3800/3800 to make both digital negatives and K7 Piezography prints on paper by means of different profiles, and switching out a couple of the inks in the system. 

"This update is a way to use both Piezography Digital Negative and the Piezography K7 printing systems together by swapping out two ink positions and using newly reorganized QTR curves when one wants to make digital negatives – and then swapping back in the two original Piezography ink positions in order to make prints."

You can basically switch the inks with a couple of power cleaning. The switch does waste some ink, but gives you the flexibility of making high quality K7 monochrome prints and digital negatives.

What you lose, obviously, is the ability to make color prints.

May I ask what sort of density range it achieves on a carbon print and if you have to truncate the curve to a suitable density range in photoshop or have it truncated for you by inkjetmall people?

Thanks
David

Re: "starter profiles" for digital negatives

2012-06-26 by SandyK

David,

I am using the profile "PZDN-X800-Meth3-1_8.quad". With the Methodology 3 ink set and the Epson 3800 this profile gives a density range of about 1.8 with green light and about 2.8 for UV processes on Pictorico.

No truncation is necessary with carbon transfer as we can adjust for the density range of the negative with the strength of the dichromate sensitizer. So I am matching shadow density of the negative with time of exposure, and highlight density of the negative with the strength of the dichromate sensitizer. 

When looking at the Cone literature be aware that his density range data is for optical (green light I assume), not UV. By my estimation the UV DR of his quad profiles for digital negatives is about 50% higher than the value given.

I have installed this inkset on my Epson 3800 and am getting negatives for carbon printing that are much freer of artifacts than I was ever able to get with the Epson K3 ink set.
