Re: [ECI-EN] Question about ICC profiles provided by ECI

Salut Hervé, PSR (Process Standard Rotogravure) has developed through decades based on the high quality print output in publication gravure. One power of the Gravure printing process is the intensity and gloss that a gravure ink recipe delivers on dark colors or image content. You'll not get that density in a traditional Offset print. This brilliance and power of a gravure printed image is partly achieved through a lot of ink and varnish on paper. Therefore TAC was set high. Depending on the printed job and due to improved separation algorithms in prepress, most of the jobs would today print with lower TAC. A final job-/engraving-/ink recipe-/paper-dependent optimal separation and TAC is mostly done in the best way in the prepress at the printers ... as they know best their conditions and capabilities. One other pro-aspect for a high TAC is the retouching quality. In a ECI-PSR-separation you are getting very even separations with CMY that goes harmoniously stronger into the dark end of an image. With many separations that are using a lower TAC from scratch, you get inversions of CMY in the dark ends ... and that’s not helpful at all for any CMYK-to-CMYK retouch or adjustment. (that’s why retouch should be in RGB ;-)) Cheers Juergen -----Ursprüngliche Nachricht----- Von: eci-en-bounces(a)lists.callassoftware.com [mailto:eci-en-bounces@lists.callassoftware.com] Im Auftrag von LYAUDET, Herve Gesendet: Donnerstag, 16.

We work with many printer house (imprimeur) in Europe, but they want a TAC at 270/280% for SC and LWC papier. If we use TAC 360% the document is separated with color serveur to lower the TAC by the printer. Why the ECI profils have a TAC as up 360% ? Sorry for my bad english.
