Hi, 

I refer to the post here: <http://www.adobeforums.com/cgi-bin/webx?128@@.1de6562b> 

Does anyone have the definition of the Elliptical-P? Would love to see it. 

Thanks! 

Regards, 
Victor Lee.

I think there is no definition for _the_ elliptical dot. But I have _a_ definition (the one from Linitype-Hell for the RIP50). It is a bit lenghty to post here. If you give me your e-mail address, I could forward it to you.

Helge, 

Hmmm ... unless it is copyrighted or something why not post it here for everybody's benefit?

Victor Lee.

I believe that the "EllipticalP" spot function, used by
ECRM/Harlequin RIPs, is more like what would be called a "diamond"
dot in traditional screening than a standard elliptical or "chain" dot.

I knew I saw it somewhere before! Thanks, Aandi, for pointing me to the right direction! 

Hmmm ... but where is Elliptical-P? I don't see anything that Mike described offhand.

Victor Lee.

Victor, 

of course the PS interpreter doesn't care about line endconventions etc, but a nicely formatted program is much easier to understand by a human reader; that was my concern.
