    Default 1200 dpi Resolution giving strange colour on text

    We have a Canon C5235i with a B2 Fiery RIP. Withe the Resolution settings set to the higher 1200dpi, most text sent on a CMYK job comes out a different colour to any graphics based on the same colour, and also have a strange "snow" effect. If we drop the resolution back down to 600dpi, the print looks perfect.

    Any ideas?

    It's sounds like an interaction with the text screen used at 1200dpi by the engine.

    When printing at 1200dpi, that engine uses a fixed screen for text regardless of the settings under "Printer's Halftone" under the "Image" tab in the driver- Whereas at 600dpi, you could set the "Printer's Halftone" setting under "Image" to a setting such "Resolution" or "Gradation" (or Printer's Default) and have all objects (image, graphics, text) use the same screen at the engine.

    For workarounds - You can either flatten the entire job prior to print (if your graphics app has this ability - such as in InDesign) - or - Just print at 600dpi for this kind of job.
