problems with spots colors and printing

Hello everyone,

 

I am currently working on a business card for a client.  The design calls for white text with an inner shadow to sit above a bar with a gradient. One of the colors in the gradient is reflex blue. When I export the file to a pdf and try to print it the text box fills with white and the graident bar changes colors and a portion of it becomes solid. I can fix the problem by printing the pdf as an image or removing the reflex blue and substituing it for another dark blue.  However there really isn't a close match in cymk to Reflex Blue C. Is there a way I could continue using reflex blue ( incidentally that is one of the company colors) without these short of issues? If it helps I am using Indesign cs5,  Acrobat X, Mac OS 10.6.8, using Creo Rip Software and Printing on a Xerox 700 digital press.

    yep, spot colors and transparency need caution.

    If possible, place the live type on a higher layer than the gradient.

    What are the export settings? (Not x1a)

    Keep the transparency live, unflattened. (?) The Creo should manage.

    I tried to replicate the issue but there are vaiables; RIP's and Flattening.

    "One of the colors in the gradient is reflex blue." And the other color(s)?

    I'm not a fan of mixing spot and process in a gradient, but I suppose it should work.

     

    As Daniel said, expor to Acrobat 5 or higher compatibility to keep the transparency live, and see InDesignSecrets » Blog Archive » Eliminating the White Box Effect

    I don't think so. Is overprint preview on in Acrobat?

    In Acrobat X, open the Print Production panel under Tools. It's not one of the default panels so choose Print Production from the Options menu (tiny menu upper right). Then select Output Preview. When the Output Preview panel is open, Overprint Preview is turned on. (It's also turned in all cases for PDF/X files.)

    You can also turn it on in the Acrobat Prefs.

    However there really isn't a close match in cymk to Reflex Blue C...and Printing on a Xerox 700 digital press.

    The spot has to get converted to CMYK somewhere—the Xerox press isn't printing a solid spot color so there's no reason to spec the color as spot. Try setting the color to the Process Lab version of Reflex Blue, export as PDF/X-4 and let your RIP make the conversion from Lab to the press profile:

    Double-click your Reflex Blue swatch in the Swatches panel. Change the Color Mode to Lab (it's at the top of the popup list), then change the Color Type to Process.

    Also, looking at your screen capture, there's no reason to use transparency, but if you are set the Transparency Blend Space under Edit to RGB
