QTR-Quadtone RIP

Hi,

I'm trying to use PSE 10 and Curvemeister to create .acv curves to use in QTRGui Curve Creation (load curve).
But QTR shows an error. 
'usage: qacv filename.acv curvenum>curve.out
CMtest.acv did not return valid coordinates at quadprofile.pl line ??
Curve Creation  failed'

What .acv files are accepted by QTR?

Thanks,

Frank

Usually the issue is that its an RGB acv file rather than a grayscale one.
You need to have a grayscale image open when you are creating the
acv file.

Thanks, Roy.

I hexedited some acv files and soon found the culprit.
It turned out to be an error in Curvemeister grayscale: it was creating acv files with 5 sets of data points, one of which (the 2nd) was used as the single active channel.
QTR only accepts acv files with 1 channel indicated and the data in the first set.

I think Mike is looking at it now. Shouldn't be too hard to find a solution.

Roy,

Looks like there's maybe more to it than I thought.
There are two versions of ACV files, 1 and 4. Version 1 is pre-photoshop 6.0 and version 4 is the version since PS6. Version 1 files differ from version 4 files.
Since Curvemeister supports PS5.5, it writes version 1 files and Mike is reluctant to change to version 4, which is perfectly understandable. PS6 and on reads version 1 and 4 and writes version 4.

QTR on the other hand reads version 4 grayscale. 
Would it be too much to ask to have QTR also read version 1 ACV files?

Thanks.


Frank

I remember the 2 acv files types from years ago.  I've looked at the code
and
it sure looks like both are still supported.  Can you send me a problem .acv
file so I can check it out.
