Question

Opacity Changes the color of other items on the page

Hi,

when I reduce opacity of a rectangle frame tool on a page in indesign the fill color of the other rectangle frame tool on the same page changes (becomes darker). When I make the opacity %100 the color turns back to its original.

appreciate any help

thanks

Just a caution about eps graphics. They cannot color manage, and so might conflict with the rest of the layout in terms of color management. I recommend you convert them to .ai files, which can color manage.

Hi @MDDSGNR ,

Rob already gave you the "why"…

To make it possibly more clear:

The colors will not change if you add transparency ( e.g. through an effect ) to an object on the spread. Also objects on the pasteboard do count! And objects on all other pages of a spread.

The only thing that will change is the preview of the elements. The actual color does not change.

This goes for all InDesign documents that are created with Print Intent where the default value for Transparency Blend Space was not changed.

Hi @Laubender ,

The color absolutely changes into darker tones. When I get PDF of the indd file I can see the darker (changed) colors on the pdf. By the way when I remove the images with psd, ai, eps extension on the page the colors of the table or other objects such as rectangle frames turn back to their original colors. There was no such problem before the last two updates. May be later updates might fix the issue.

"The color absolutely changes into darker tones."

Hi @MDDSGNR ,

not in InDesign. If you see this in an exported PDF the color was transformed with the export process.

You could export to PDF/X-4 without any color transformation or transparency flattening and the values for your RGB colors will stay as they are in InDesign.

To check this use Acrobat Pro with the Object Inspector in Print Production's Output Preview.

You might experiment and see if all the elements on your page agree as to basic color model. I like to be all one way or all the other when it comes to graphics being RGB or CMYK. Also check under Edit > Transparency Blendspace as to which way it goes. Also, you might check the document setup for intent of either print CMYK or web RGB.

Thank you Mike, my document setup for intent is "print" and transparency blendspace is also CMYK. I don't know what's the problem. This is the first time I've encountered such a thing.

Would you have inadvertently applied an Object Style that's now the default?
