How to produce neon glow effect for cmyk print

[CherieGrist]

Hi everyone, 

I'm wondering if anyone knows of a way to print a neon light tube effect but for a CYMK print?

My RGB one is looking good using the different colour glow effects but when I converted to cmyk  and changed the colour codes and placed back on black background all the coloured outer glows turned white?

Thanks in advance for any tips!

Can you show the design?

There are probably a lot of raster based effects. This will be turned into raster images anyway when you export a PDF for print, so why not export the RGB version as a raster image at a sufficient resolution and then place it into your layout and then generate the PDF?

Cherie,

I am afraid the long answer is the use of additional inks.

Some printers have inbuilt additional inks for vivid colours, and then there is the option of spot colours/inks, depending on the way of printing.

Neon colours and CMYk are a bit like fire and water.
