Export With Transparency / Set Page Background


Question

I am new to InDesign. I have been supplied a file with a number of pages consisting of tiff images. I was told that the tiffs have transparent backgrounds, but when I export to png, the entire page is filled with white with no transparency. How can I export or set a transparent background for each page please?

Accepted Answer

Unfortunately InDesign does not use transparency information stored in a TIFF file. It always fills transparent pixels with white color.

However, InDesign does use the transparency of placed PSD files. So I would recommend opening all of your TIFFs in Photoshop and resaving them as PSDs.

Edit: the answer above is proved to be incorrect - I've always tried to place a layered TIFF file containing a single layer with transparent pixels which is NOT the same as a TIFF file properly saved with transparency.

Tiff files MAY have transparency. But traditionally they do not.

Adobe added the ability to save transparency in tiffs a few years ago, but that does not mean everyone uses that feature.

If the tiffs have background, you'll have to remove them just as you would from any other image via brushes, selections, and masks in Photoshop or some other raster editing application. Indesign will not auto-generate transparency where none exists.

Note Tiffs CAN contain transparency and be placed in Indesign....
