Looking for some help rasterizing / flattening a complex image.

Here is the image in Illustrator as it should look, placed on a white background.

correct display of image in question

The image needs to ultimately remain a vector EPS that can be placed on different backgrounds, etc. However, when it is placed on a coloured background, the shapes and paths I overlaid to create highlights are visible. Here is the image moved off of the art board so you can see it set on the grey:

How do I rasterize / blend the shapes so that they do not appear and simply function as a highlight effect?

This is the file: http://hospitalgrade.net/media/object-blue%20grad-highlight%20adjust.rar

Note that based upon the file it could be cleaned up to remain vector and retain the appearance without the use of blending modes (which are why teh white appears n dark backgrounds). Unfortunately, explaining how one would go about that in any sort of procedural fashion would require perhaps an hour long video seminar or a 30 page message board post. It's simply not feasible to explain, especially in this format.

The short answer...

  • Isolate sections, expand them, crop to remove clipping paths... repeat.
  • In areas where blending modes create the appearance, add additional fills with a color variance rather than a blending mode to achieve the same overall appearance.

Option 2....

  • Create a new path to use as a clipping path or opacity mask for the entire shape.

i think the white's are additional stroke. just remove them in appearance panel. try also removing stray points. If none of these works highlight all paths or lines; expand all fill and stroke; select same black fill/stoke merge or unite them/ group them; then remove other colors except black.

  • Thank you for your response. When I remove the stroke from the white "highlight" shapes in the appearance panel, the shape / stroke disappears, but so does the intended highlight effect that it was meant to have on the paths beneath it. perhaps a better place to begin would be to ask the question - How do you give a thin line a highlight / shimmer effect with an opacity mask? It's obvious that overlaying a shape larger or thicker than the line below it leaves you with the mask shape visible and overlapping?

  • Sorry I cannot open it in mac. So you have fixed it? Feb 6, 2018 at 5:17
  • Well, yes and no. Instead of using shapes with opacity masks to achieve the "highlight" effect on the thin lines, I added a layer and drew in very fine light lines manually here and there to mimic the effect.
