Re: [QuadtoneRIP] Epson R1800 Posterization

2006-10-29 by Matti Koskinen

Hi Scott,

 I had this posterization with QTR and Epson r1800 also, but changing to 
2880 dpi from 1440 changed a lot. There were still some banding, but not 
so bad that it could be seen in normal prints. Some posts I've read said 
that the Gutenprint (on which QTR is based) is not so good printing 
solid greys and suggested setting a narrow border in the image and 
adding noise there. Look at the archives for more info. I've printed 
with 2880 dpi really nice prints. The first time I tried QTR was also 
bit disappointing, I printed a test image, which had large smooth, 
gradually darkening sky, and the posterization was enoung to ruin the 
print. Then I forgot QTR for some time, and tried to get neutral prints 
with epson driver, but with no luck. Then I decided to give QTR another 
try, and set 2880 dpi, and voil\ufffd, the prints come out very good. Now if 
someone with  skills, could make new profiles for r1800, it would be 
splended.

best
