Hi Brian:
Yes, Windows 10.
Since that post . . . in between other real work . . . I’ve been going through the curve generation and linearization routines. So far without good success. I don’t like the way the 21step prints look.
I don’t have a densitometer. I’m printing on transparent film and my scanner doesn’t really do that . . . so I’m struggling.
I’ll keep plugging at it. I don’t fully understand what I’m doing yet, but I’m further along in the process. From long experience with other technical puzzles, I’ll get this, after a few days more struggle.
If there’s anyone in the Los Angeles area (I’m in Lancaster, NorthEast of LA) who’d like a consulting gig helping me figure this out . . . I’d like to talk.
Dwight

The fact that you had this error message suggests that you're on Windows. If you scroll down the posts in this group to around 24-25 Aug you'll see that I had the same error message. I didn't ever solve it directly. It came and went several times and seems to have gone away. It seemed to be related to the number of pixels in the image file rather than the Mb size of the file
In relation to your initial problem of unsmooth gradients, I'd be more inclined to suspect your colour management settings than the file format and bit depth, although creating and printing a 16 bit uncompressed TIFF can't hurt. If you manage to get past this error perhaps you could share your workflow in more detail and esp your CM workflow & QTR settings. QTR should be able to print a pretty good gradient.

I created a 8 ½ x 11 gradient, 16 bit, Greyscale.
Saved it as a TIFF with no compression.
Now I get an error message “Unable to create TIFF Bitmap buffer”.
What to do?
Thanks!
