Re: If it isn't one thing it is another
Permissions are an ongoing issue. Some setups are for one personal computer and others
are for multiple people sharing printing -- like classes.
The default in QTR is sharing access and control of

Re: If it isn't one thing it is another
Ohhhh, crap! The commands sometimes don't display right through these emails, or on groups.io. The "escape" can stripped off the semicolon. They should really end in a backslash and then semicolon.

Re: If it isn't one thing it is another
Well, that's a shotgun-type approach that leaves everything in it's path writable by the world. Just be aware that's what it does. You may not want that.
I'd suggest this, a little more correct and

Re: If it isn't one thing it is another
My guess would be a permissions issue. I have a shortcut in the files
section of the groups.io site that will fix it. Or type this:
sudo chmod -R 777 /Library/Printers/QTR/quadtone

If it isn't one thing it is another
Has anyone seen this message and have a fix.
All my students for the last week have been printing cyanotype negs with apparently NO profile (since the printing still happens in Print-Tool).

I am getting good results with PMF on my P800 using Photo Black. I’ll post

Re: Horizontal lines
Hi Dieter,
Thank you for your answer.
I am printing DTP. Using Toyobo-plates.
These are horizontal lines.
When I turn the image 90 degrees in PrintTool , the lines remain horizontal. So it has

Re: Horizontal lines
Hi Eric,
Based on your images I have the idea those are scans from BW negatives. Am I correct? I have bumped into similar artefacts with poorly scanned or processed images from clients (i.e. trying

Re: Low resolition/“grainy” prints-negatives
What a strange issue. Seems to make more sense lately to have a computer dedicated solely to printing and not updating it until all bugs are worked out. I see and hear of so many people having issues

Re: Horizontal lines
Hi Tomas,
Thanks for your mail!
The thing is, I do DTP.
I also narrowed the platen gap from Widest to Wide, but the horizontal lines remain.
Best regards,

Re: Horizontal lines
Hello Eric,
I had the same issue with Epson SC-P6000.
I was using Tecco production SF140 film to print the negatives.
I assume the horizontal lines was caused by the substrate being to thin. 140gsm.

Re: Low resolition/“grainy” prints-negatives
I figured out, the issue was caused by the scanner connected while printing with QTR.
once I disconnected the scanner and closed Silver Fast, the prints were fine.

Re: Revisiting Carbon 6/7/8 in 2024
PK can be used on any paper. MK, not so good on glossy. Dilutions use less ink, so if you use PK for that you'll have an inkset that you can use for any kind of paper if you have 100% PK and 100% MK

Re: Revisiting Carbon 6/7/8 in 2024
thanks Walker, at a high level, what's the logic behind not diluting matte black ink? Ecomics of it, or quality?

Re: Revisiting Carbon 6/7/8 in 2024
IMO Don’t dilute the Mk. Use a gloss ink like Hd Pk for the dilutions.
Or just go with piezo because it’s properly filtered and encapsulated . . .
