photos prepared with transparent background saved as .tif when placed in inDesign CS2 and exported as PDF loose the transparent background and print as if they were on a white background.

When you save as a .tif, you are flattening the file's transparency, so it won't come through to InDesign (and will give you the white background). You should be placing native .psd files into InDesign...not TIFFs, anyway. Placing native files will retain any transparency in the Photoshop file.

If you place PDFs in a document, make sure you choose Show Import Options in the Place dialog box and select Transparent Background in the following Place PDF dialog box.

Hey there,

In response to the first response from thoward, ensure when saving the .tif file with transparency that you check "Save Transparency". This will ensure that the TIFF file will retain transparent background when placed and PDF'd through Indesign CS/CS2. (Please post again if this continues happening)

Also in respose to EKWoman, the myth that only PSD files will display transperancy is a common mistake by some photoshop users. Since Photoshop CS (after Photoshop 7) was released Adobe have enabled the TIF Format to retain transparency and contain layered files. This also makes the TIF Format superior to PSD through using LZW compression (no removal of detail) instead of the jpeg compression that PSD uses (compression through loss of image detail).

a little bit off topic now,

... but would you get compression artifacts with jpg even if you select highest / '100' quality?

No. The other myth with Photoshop is that you can't have crisp type. Anything saved at 300 dpi or higher and output at 100% of the dimensions will output as good as vector.

Unless you take a magnifying glass to the piece. Within reason. So many gripe about 'fuzzy type' but 10 times out of 10 they're outputting at something other than 100%.

For photos it's a little different. You can usually output up to 115% without seeing any major changes.

I always allude to Eric Johnson (the guitarist) who talks about being able to perceive a differece in sound quality when using a guitar cable tipped with gold rather than chrome.

It can get a little pedantic and silly. If one has to hold something up to ones nose to see 'if' it's any good, they have far larger areas of concern than the quality of an image!

But, directly related to jpeg at high compression, you can only save an image once with high compression. So many forget that each time you resave a document as a jpeg, the compression increases so that's where you could actually start having perceived artifacts with a setting of 12 in Photoshop....after resaving an image multiple times.
