Re: [Digital BW] smoothest gradient from hex/quadtone?

2004-02-06 by Mark Hahn

I would prefer printed output, then I could scan them all with the 
same scanner and settings.  I wasn't that concerned with neutrality 
since I've only seen that as a problem with color mixed b&w which 
wasn't my intent, but if they are all scanned in color you could 
convert them to LAB and take readings... of course there is no 
guarentee that my scanner is any more perfectly color calibrated than 
anyone else's, though I have built a greyscale calibration curve.  If 
there are volunteers I'll post both a smooth gradient and stepwedge.

Contact me off-list to set this up.

I think this would be of service to the whole b&w printing community 
and should be almost no effort to anyone but myself:)

thanks,

mark
