Re: Epson 3880 spitting out unprinted transparencies
My experience supports Roy’s comment. One of the curves I made just ejects and cuts the film on my Epson P5000. It was a third curve created based on a first and second curve that work just fine.

Thanks Roy
I’ll give it a shot.

Re: Gutenprint discontinuation and the future of QTR
Bummer. Any word about QTR on Windows?

Re: Gutenprint discontinuation and the future of QTR
Clay,
I dedicated an older iMac running Catalina (via a clean install). ?It is connected to a P6K running Piezography Pro inks so it is not even connected to the Internet (so no way Epson can sneakily or I inadvertently updating the firmware). ?It runs QTR and PrintTool, of course. ?I’m not a commercial studio like yours so using USB drives to shuttle images from my editing environment to printing is no issue. ?It does one thing only: ?print.

I'm curious how people are preparing for this potential loss of support on future Epson printers and Mac hardware. Does it make sense to keep a low-cost mac mini or the like around with a frozen-in-time version of Mac OS that can serve as a print server??

How to increase negative density
I have a linearized quad
curve using the DN Pro program, Boost is near 100, how can I increase the ink load of density of the Fixxons neg without using any Magenta or Yellow ??

Thanks in advance?

Same as .txt files:
From the mac Tutorial for QTR:
"a .txt or .qidf extension is an ink descriptor the "source" code for creating a profile; a .quad file is the "binary" profile format. The installation scripts handle all of these formats."
|
Hi everyone,
I recently downloaded several printing profiles for photopolymer plates, and they are in the .qidf format. Typically, the files I use for curve linearization are either .quad or .txt, but I'm not familiar with how to work with .qidf files in QTR.
Does anyone know how to use these .qidf files in QTR or how to convert them to .quad or .txt? I haven't found any information on this so far.
Thanks in advance for your help!

Linearize with Datacolor Spyder Print
Hello everyone!
How can I linearize with the spyder print spectrophotometer?

I use QuadToneProfiler-Pro-DN by Richard Boutwell.

Re: QTR Missing "Printer Features" (cannot select paper type)
I think you are mixing up different things.
The only thing you do in QTR is select Curves which are often tailored to different papers.
There is no "select paper type". There's nothing to work around.
If you use the Epson driver that, yes, you select different papers. But that's got nothing to do with QTR.
Both Print-Tool and Photoshop are just Apps that call different printer drivers (Epson or QTR).
They have select ICC profiles which usually have paper names.

QTR Missing "Printer Features" (cannot select paper type)
Hi everyone,
?
New to the group, so I hate to start with a request rather than to offer help, but hopefully someone comes up with a problem I can help solve soon.
?
I've been struggling to diagnose an issue with QTR. For the past few years I've been printing digital positives successfully from my 2020 MacMini (M1 chip, running Sonoma OS 14.6.1) to my Epson 1430 with a CISS system. A month ago (pre-Sonoma update when using Snow Leopard OS 10.6) my prints suddenly became very grainy. Nothing had changed about my materials or operating system at the time (epson may have updated the printer driver though). I use Pictorico OHP and grayscale dye-based inks. I reset my printing system, uninstalled and reinstalled QTR, updated my OS, fully flushed, cleaned, and updated the printer. My prints still came out grainy even when running calibration prints. While auditing my workflow, I noticed that "Printer Features (or Options on newer OSs)" and my ability to select a paper type had disappeared from the print dialogue box, both when printing through QTR on Photoshop and the Print Tool. However, those options still exist if I'm using Photoshop to print directly with my printer without using QTR. I know that you can choose paper type in the "Print Color Management" section of the Print Tool, but my process requires that there's no color management (smarter people than me working in Photogravure have determined this to be necessary).
?
Has anyone had a similar issue? Should I somehow return to an older OS? Is the issue not a software one? Maybe there's a workaround?
?
Thanks for your help in advance!

Re: Ink Mismatch - Quick Curve - P900
#problems
I wrote a script for my own needs that made up a MK curve from the PK values in a .quad file. In my case, I wanted the MK to act as a "boost" for the PK at the denser end of the range (dense negative, that is), so I made it ramp from 0% of the PK at 0, linearly to 20% of the PK at 256 (the dense end of the curve).
If you can read Unix Shell and awk, you? are free to use the following. (You'd paste the following into a file, let's call it PKTOMK.sh, mark it executable via chmod +x PKTOMK.sh, and then run it on your favorite quad file via PKTOMK.sh myfavorite.quad? where it will produce myfavorite.quad.edit.? You then have to rename the resulting file and install it in the usual way.)
#!/bin/sh
if test $# -lt 1; then ?echo Usage: $0 inputfile [pk multiplier]; exit 1; fi
MULT=${2-"0.2"}
sed '/MK Curve/,$d' $1 > $1.edit
awk 'BEGIN { process=0; mult='$MULT'; i=0}
/# K Curve/ { process=1; print "# MK Curve"; next}
/# C Curve/ {exit 0}
/^[0-9]/ {if (process == 1) {$1=$1*(mult*i)/255.0; i=i+1; print;}}' $1 >> $1.edit

Re: Ink Mismatch - Quick Curve - P900
#problems
Hi!
I’m the same curiosity. The P700 has the MK which is a magnificent UV-Blocker but it’s not used in the QCDN curves.

Re: Ink Mismatch - Quick Curve - P900
#problems
Solved. The download that came with the original sign-up is for 2.1.2. In the program i checked for updates and there was a fix for this in version 2.3. I downloaded that and it worked fine.
|
I'm stymied with this one.
I created a cyanotype curve using QCDN using?
Saved it with the name Cyanotype-Starter.quad
Pasted it into the P700-900-UC folder
Ran the install InstallP900.command I get this error in the terminal
"Inks mismatch: PPD has K,C,M,Y,LC,LM,LK,LLK,V,MK and Quad has K,C,M,Y,LC,LM,LK,LLK"
Looks like the ppd is looking for 10 inks and the quad file has 8? Missing the V and MK.
I'm running QCDN 2.1.2 and QTR 2.8.2.
Any help would be appreciated.
