Re: banding and dithering with QTR and UT14 Epson 1500 (1430)

Once again, thanks for the time and input.

I have now used the cool and warm curves mixed and am getting much better wedges.  I've compared these to a print via the Epson driver and they are way smoother.  2880 resolution uni-directional definitely gives the best result.  Comparing these to a print using the Epson driver shows the QTR prints to be much smoother, even when viewing from several feet away I can see graininess in the Epson print.  Looking at the earlier Claria prints I can see the artifacts are mainly noticable in the black-only prints.

I'd run off a few image prints and was getting a flatter and lighter print than the screen image.   I thought I'd better start some wedges for profiling and was trying to get a good baseline print.  I started with the curve at the top of the list, which was the black-only and then tried changing all other variables, one at a time, which with paper-loading issues and numerous spurious duplicate prints was starting to really frustrate.

Had I started with changing the curves instead of everything else I would have been happier quicker!

I am probably trying to run before the crawling and walking stages are complete.  I only bought my first digital camera 8 weeks ago and am trying to be where I was with my wet printing using all analogue techniques.

regards

Ross
