Color transparency issue with ai file in indesign

[Optimistic_speaker16B8]

I have an advertisement that I designed in illustrator using rgb color mode.  It has gradients that use layer modes that only fade correctly in rgb mode.  I placed this illustrator native document into indesign and indesign destroyed all of the blending of the layers.  I believe that this was due to color mode conversion.  I use indesign to convert all of my images into CMYK for offset press printing.

What happens if you convert to CMYK in Illustrator?

It appears the same as in indesign with the lines.

Most of it is a raster image anyway, isn't it?

So why not export a flattened raster image from Illustrator?

Or select all and apply Effect > Rasterize with sufficient resolution and then place into InDesign.

The background gradient mesh and the glowing lights are vector mixed in with some raster pictures.  If I have to I will flatten transparency or rasterize but on some of my other projects this creates added steps that I am hoping to avoid especially when we are in  the design process and making changes and printouts left and right.

That's why I suggested to select all and apply the rasterize effect.

I forgot: the artwork needs to be grouped.

Alternative: Create a top level layer, move all other layers into it and then apply the rasterize effect to that top layer.

Hi. You can export as PDF to maintaining the vectors and import that PDF in InDesign.

When you save an AI file as PDF compatible, you are basically doing the same thing.

When you Save or Export to PDF, you can define what kind of PDF you will create using the settings or presets, so it is not the same.
