Gustavo Irrational Tangent Screening is described in Prepress's Tech reports. It appears to be an approximation of the requested print effects (angles, screen frequencies) using conventional AM screening technology. See <http://www.prepress.pps.com/TechReports/screeningtr.html#irrational> Supercells are described in Adobe's Technical Support database <http://www.adobe.com/support/techdocs/210f6.htm> as a technology which increases the number of gray levels available to a printer, thereby improving graduated screen appearance. From what I can see (not having tested this), irrational screening pushes existing print devices to create visual illusions, while supercells attempt to improve device performance using more specific technology. Hope that helps. Gunnar
