Print Tool settings for digital negative

Print Tool settings for digital negative

2014-02-25 by <luciano@...>

I have one more doubt about Print Tool.
I have created a custom curve based on the results from the Ink Pattern Page.
Now I am confused because my initial though was to use No color management, and select my curve in the QTR print dialog. If this is the case:
1) which profile should be embedded in the image file?
2) And, how do I tell QTR the type of paper? (in this case glossy as I am printing on Pictorico).

If instead I need to use Application Managed, could you advise on:
1) the profile to use (maybe QTR_RGB_Photo_paper?)
2) which intent should I select (my guess is Perceptual)

Thanks,
Luciano

Luciano,
Here is how I print digital negatives with the Print Tool.
1. First, make sure the image file is saved in Gray Gamma 2.
2. Open the image file in Print Tool. It should open with the embedded Profile Gray Gamma 2.2
Choose "No Color Management" and Click Print.
3. In the second dialog box choose your Quad Printer. Then under Layout choose QuadTone Rip.
4. One you choose QuadTone Rio a second window will open where you choose your Curve (or profile that you have installed), Paper Feed, Resolution, Speed and type of Black Ink. For printing on Pictorico I recommend Resolution = 2880 dpi, Speed = Uni-directional, and if using the Epson K3 ink set, Black Ink = Photo Ink.
No need to click on Advanced Adjustments for Ink Limits and Gamma since you will have have adjusted this in your linearized profile. Type of dither "may" alter grain structure a bit, I generally prefer Adaptive Hybrid.
Once you have made the selections you can save the settings under Presets.
This is all pretty straight forward once you do it a couple of times.

Hi Sandy,
Thanks. My printer is an R2880 and I have loaded Photo black as I can only load one black ink at the time, so either photo or matte. This is probably why my Black Ink drop-down is greyed-out. I guess the printer & Print Tool will handle the paper type correctly, right?
Thanks,
Luciano

Problem solved: I actually discovered that after selecting Print in Print Tool, there is one more option in the drop-down, immediately after QuadToneRIP, called Printer Features and there I can select the Media Type (Photo Paper or Matte Paper).
Cheers,
Luciano

Luciano,
You are right. The black ink setting is grayed out because there is only one choice, i.e. the one you have installed.

And there is no paper selection with Print Tool. The ink settings for a specific media would already be built into the QTR profile.

Luciano,

Once you select Layout > QuadToneRip I don't believe it makes any difference which media (matte or glossy) you select in Printer Features. Print Tool is going to use the black ink selected in the QuadToneRip dialog box, and put down ink according to the Curve 1 you have selected, and according to paper feed type, resolution, and speed.

Sandy,
I guess it doesn't hurt to set the paper (just to be on the safe side). I printed the negative this afternoon and I am waiting for it to dry. By looking at it, it's way more thin than the previous test I printed just winging the numbers in a profile but that should be OK as I need to print it with gum. This time I used the UV test chart in QTR to print a test tablet and get some real-life values (using the steps documented by Clay Harmon). I hope to print the new step tablet in the next few days, and probably ask for advice...again.
Thanks for the help.
Luciano
