QCurve did not return a valid curve at quadprofile.pl 184

QCurve did not return a valid curve at quadprofile.pl 184

2009-11-07 by purduephotog

After a year off (birth of first child, hardware failures) I'm trying to pick back up with my BW printing.

Unfortunately I've actually lost progress.  I had to reinstall QTR and now I can not perform even the simplest tasks.

When I grab any qidf file and try to use 'show curve' I get the above mentioned error.

I'm still trying to create a valid output profile that uses 3 inks- K, M, and Y (I'll duplicate it and rotate it for C, LC/LM).  I love the look of the BO but I'd much prefer to have smoother tones.

SO, in short, can anyone set me back to progress?  And are there any other automated spreadsheets or, perhaps, better documented methods for producing curve files?

Thanks in advance!

Jason

Showing us the .qidf file you are using would help.
Are you using curve files such as a .acv or .raw ?

My apologies, but when I said any .qidf curve file- I literally meant *ANY* file.

I'm using the Epson R280-MIS.  I specifically had interest in the MK-Red-River-Polar-BO.qidf file as I have that paper.  When I load it and press 'show curve' I get an error.

I reinstalled QTR and the curve creation tools so I know they're fresh/clean and haven't been tampered with.

I haven't even gotten to the point of editing the curves for ink lay down as I can't even graph the default ones.

Thanks in advance-

Jason

Re: QCurve did not return a valid curve at quadprofile.pl 184

Are there any dependencies, such as dlls or other unique programs, that might start causing QTR to behave badly?

I even tried disabling all processors but 1 (I'm on a quad) to see if that would prevent the error messages.

If I open any QIDF, from any folder, and hit 'show curve' I get variations on the same error.  Sometimes it's qdotgain, sometimes it's qcurve, line 81 or l84.

Fresh install?  Yup.  4x.
