Re: Endless (CO) Dotshape
In FlexRip, the CO dotshape behaves like the normal circular (C) shape, but the screens are optimized for making seamless sleeves on the CDI. Years ago, the CO shape was the only way to do seamless, but in more recent versions of FlexRIP you can make other dot shapes seamless by selecting the "Seamless" screen type in the RIP expose ticket (seamless screening is a payable option). You will find more details on the dot shapes etc in the Screening manual which is included on your Esko installation DVD.
Hope this helps.
