1. Best quality from scanner to Calcomp under NeWSprint?
I am scanning photos with an HP 3c scanner, which I believe is 1200dpi. The
photos are ~3"x3", and I am scaling them when I scan them to ~7.7"x7.7",
which gives about a 1100x1100 dots. I do not understand why I am not getting
at least 3600x3600 dots, but am more concerned about how to get the best
output from what I have.
Next step: I have a Calcomp thermal wax printer connected to a SPARC with a
parallel port and controlled with NeWSPrint 2.5?. Either using xv2.21 or
the tiff.2ps that comes with NP to convert the image to PS, I end up with
quite a few dithering-looking marks. Even funnier, it does not make any
difference in the quality of the output whether I am sending a 1.8M file
generated with xv from a 600x600 dot tiff, or a 3.8M file generated by xv
from the 1100x1100 dot file, or an 8M file generated from the 100x1100 dot
tiff with tiff2.ps.
I would like something that looks more continuous in color scale.
I also tried converting to ras, but that printed with some real weird color
I cannot seem to find a definitive list of the other graphics formats that
NeWSprint supports. Are there others?
Any other hints?
