QTR-Quadtone RIP

Thanks to help from Richard and Roy, I was able to print Inkseparation images 
for linearizing my K7 inks to use in making digital negatives. I printed 
several inkseparation images at different ink limits to get the density range 
I desired. Densities were measured with an X-Rite 361T UV densitometer. 
Insertion points for the inks were calculated using an Excel math program and 
then transferred to a .txt profile. When attempting to run the install file to 
create and save the .quad file, I got an error message stating that the file 
could not be saved in the /Library/Printers/QTR/Quadtone/Quad7600-K7 folder 
because permission was denied. This is due to El Capitan's SIP function. 


I can disable SIP and allow the action. However, I thought this problem was 
solved in version 2.7.7. I am pretty sure I installed it before I installed El 
Capitan. It is also possible I am mistaken on when I installed El Capitan. In 
a post on removing files on Nov 3, Richard provided the following string as 
the site where the files were relocated under SIP as 
/Library/SystemMigration/History/Migration-(some UUID)/QuarantineRoot/. I went 
to this location and found nothing intelligible- to me at least. I took this 
to mean that no files had been relocated, e.g; I installed El Capitan after 
QTR 2.7.7. I may be confused on that as well. 


My question is: can I fix this so that I don't have to disable SIP every time 
I want to add a profile? Thanks in advance for any illumination. 


Cheers,

I got that too when installing new printers after updating, but that isn't an El Cap SIP issue. It seems to just be a simple permissions setting for the quad folder.

Navigate to the quadxxxx-k7 folder, right click and get info (or just command+I) and change permissions to read and write for the admin user account (I chaged it for all three user account I have there). I'm not sure why that changed but it took me a minute to sort it out when I first ran into that. I should have posted something about it then, but I was too eager to set up the new printer and completely forgot about getting back to it.

Hope that fixes it

Richard, 


Thanks for the quick response. My quad7600-k7 folder is at the end of the 
string starting at library/printers/QTR etc on my boot drive. When I went to 
that location and right clicked for Get Info I was not allowed to change the 
permissions. That's why I assumed it was a SIP problem. I must be doing 
something wrong. Suggestions? 


Cheers,

FYI: You'll want to do this (procedure listed in previous comments) every time you install a new (or edited) curve. 

It is a permissions issue, doesn't always effect El Capitan but I'm seeing it every time w/ El Capitan right now. I'm currently in testing of QTR and 10.10 at InkjetMall (Piezoland)

happy printing all,
Walker

Charlie,

Did you click the little lock icon at the bottom right of the info window? You're be prompted to enter your password and then you can change the permissions. Then relock afterward... After doing that one you shouldn't need to change again. I found that I needed to change the permissions for any printer I added/installed after upgrading to El Cap, but printers that were there before upgrading were fine. Weird right. 

HTH,
RB

Richard, 


Thanks. That worked. I had overlooked the little lock. Too much snow removal 
over the last 4 days ;-). 


Cheers,

Roy:

 

Since I continue to use Windows 7 I have not felt the need to update QTR.

 

However, I suspect that eventually I will need to install Windows 10.

 

Will there be an update for Windows 10 or will we need to have a computer with Windows 7 installed in order to use QTR?

 

Elliot

There is no problem printing Piezography on win 10, so you shouldn't fear updating.  the only issue is what has been discussed before with the curve creation module/mode. Even that still works but it isn't as smooth as it used to be.

Roy has addressed the problems updating the Windows QTRgui previously in other threads.

The release notes for 2.7.7 are about El Capitan compatibility:

This is a Mac OSX only release specifically for OSX El Capitan compatibility.

El Capitan prohibits installations in an area that was used by QTR so this update moves

those files to a permitted area.

It's recommended that you update QTR to 2.7.7 before updating your OSX to El Capitan.

This cleans out the old locations while access is still permitted.  If you don't QTR still

will work just fine but if you Add Printer in System Preferences it will appear that 2.7.6

is still installed -- in fact this will point to new code but the 2.7.6 may be confusing.
