PNG with transparent background, placing into Illustrator with white background.

[EcoCreative_UK]

I'm placing a PNG file with a transparent background into Illustrator and it's showing a white background in the file. I've managed to remove the background again by selecting the 'Opacity & Mask Define Knockout Shape' tick box in the Opacity settings (image below)

 

However, when I save the file as an PDF, the white boxes re-appear (image below)

Can anyone please help to find a solution to this issue or know what the problem could be?

Thank you!

Please show screenshots. Exactly what are you doing step by step?

A new thread might be a good idea, because this one is already a mess.

Also having same problem - have tried as PSD, as PNG, CMYK, RGB - the file is transparent in Illustrator but the image files have a white background when exported as EPS and placed in Indesign or opened in Photoshop. The only workaround is to export from Illustrator as PNG - but I need to have vector file so that doesn't solve the problem.

First image shows Illustrator file (clearly with transparent background); second image is the EPS file.

An EPS cannot be transparent.

Try PDF instead.

Same problem - workarounds tried RGB vs. CMYK color space, PNG vs. PSD file - no luck. Image placed into Illustrator has transparent background - when exported or saved as EPS the images have white background. All settings are checked for transparency. Only workaround is to export as PNG - but I need a vector file.

First screenshot shows AI file (transparent), second shows EPS (white background on the two flags).

Just place the Illustrator file in InDesign.

By default (and i dont know why doesnt make any sense to me), illustrator as white background as colour. you must go to asset export panel > Format settings and then in background colour > Transparent
