Re: Linearization tab in Curve Creator tool

2007-07-17 by David

Thanks Roy. 

So if I understand you correctly, this curve is "lowering" or
lightening the black because the paper won't accept pure black? Is it
lightening the black or applying less ink?  

And when I applied the raw curve (UCmk-raw-neut.qidf) when I
printed--which has a blank linearization table--it printed, or tried
to print, full black to white? 

Best, David.
