    Camera-to-plate CMYK help

    JLeedyNC5-Etwl7r

      We recently upgraded to CS5 from PageMaker and have begun using InDesign to paginate a broadsheet newspaper, printed on our King offset web press. Although we plan to upgrade to CTP asap, for now we need to continue with our old production workflow, which is printing separations to a Xante Accel-Writer, shooting those with a camera and generating plates. We're happy with our results for black and white, but are pretty sure our halftone settings are wrong for CMYK. The dot pattern just isn't there and our colors are coming out poorly. We notice that the North American press setting in Bridge assumes that we use a CTP. Can anyone help with proper color settings in InDesigns, and/or Bridge and Photoshop in CS5 for our workflow? Thanks.

          Color Settings affect color conversions RGB>CMYK or CMYK>RGB, but not dot patterns. If you are having problems with halftone angles or dot rendering the problem is with the output device and/or the camera.

          North American Prepress preset uses the US Web Coated profile for CMYK conversions, which would not be the correct profile for printing on newsprint. Ideally you would want to have a custom profile made from a target press sheet, if that's not possible at least use a newspaper profile like SNAP 2009.

            If you are using the workflow i think you are you are in trouble. You could be having trouble with the laser printer or you could be losing dots and resolution in the Dark room. you have sheet sizing from the printer to the dark room. you need to change to ctp asap. If that is to expensive an imagesetter is a great choice and cheaper since ctp.
