I'm designing a document in InDesign where there is a vector image. To make the background seem continuous, I pulled a rectangle (sent it the backmost) and copied the color of the vector using the eyedropper tool into the rectangle. In short, I wanted the background color of the vector to be continuous with the whole document.

It worked great even on InDesign preview, but after exporting to PDF, there's a change. Could anyone pls help as to why this is happening and how to prevent it happen. Because, it would look ugly to have a border show up, which I was trying to conceal.

In InDesign,

Theres a slight difference in color in the right half in the lower image, if you could appreciate. That is my concern

When sampling linked vector images in InDesign with the eyedropper tool, what is sampled is the RGB preview. In fact, I believe InDesign throws up a warning stating this when you do it. So it's best guess and never guaranteed accurate.

If you want the same yellow.. get the CMYK numbers from the vector file.. then fill the InDesign element with the same CMYK numbers not a sample using the eyedropper.

  • If it is an AI file, the swatch will get imported with it if I recall correctly.

  • @Yorik If the Ai file has spot color swatches those swatches will get imported. I do not believe CMYK, RGB, gradient, or pattern AI swatches get imported.

  • It's an EPS file does it makes a difference?

    @Polisetty I don't think it does. InDesign only sees spot color swatches from linked files. I'd honestly have to test EPS to be certain though. I haven't used EPS in years.
