With the help of Chris Anderson’s Ilford Classic and Warm-tone quad files I’ve have had good success in linearizing D Neg files. Also, vintage Portriga Rapid linearized very easily. However, beginning with the Lodima starter curve the lighter curve values for vintage AZO grade 2 simply will not linearize proportionately. Any suggestions ?? Thanks in advance.

Can anyone offer a suggestion on what the fix is for this mess ? Have completed a Power Cleaning, Head Alignment and installed new Maintenance Box. Thanks !!

Greetings, Anyone have a suggestion on how to correct the blips seen in the photos of higher values for both Ilford Warm Tone, and Ilford Classic silver gelatin multi-contrast papers ?? Repeated re-linearizations does not correct Thanks in advance, Steve Sherman

Hi, I'm writing a quick script to serialize a curve defined in an acv from Photoshop to a string compatible with the GRAY_CURVE parameter in an ink descriptor file. Adobe's documentation defines each curve point pair as the output value followed by the input value. Additionally, each coordinate is a value in the range of 0–255. Two questions: 1. Can anyone confirm whether GRAY_CURVE expects the format input;output or output;input? 2. Does 255 == 100 in GRAY_CURVE or is the value similar to the ink percentage in Photoshop where 255 == 0? Thanks.

Hello to all! I hope I’m not out of topic, but in my P700 when I print lately I see stripes made of dots where there is no ink or it has been taken away, attach photos. Thanks for help. Enrico

Hi, I'm wondering if anyone out there has worked out how to save printer settings presets? I'm using the Epson Quad driver with Sonoma 14.5. I have tried to set up the presets as a 'custom' as well as a 'print job preset' as well as a custom preset, but they are not sticking. I know this has been a problem for a while but what has really confused me is that I had it all set up and working for a while and then the presets disappeared when I installed a new qtr curve. Very frustrating as you can imagine. Any help would be wonderful.. Thanks! Silvi www.silvi.com.au

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! Nick

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.
