If you have an image that appears to have solid white areas (maybe the background surrounding a logo), but when you put the Eyedropper on that area, it gives you a 1% or 2% reading in one of the CMYK values in your Info palette, you can use Levels to gets those areas back down to 0% so they don’t print with a dot. Here’s how: Go under the Image menu, under Adjustments, and choose Levels. The third field from the left (at the top of the dialog) shows your current highlight value (your white point setting). The default value will be 255. Enter 252 or 250, then move your cursor over the white area in question and look in the Info palette to see if the readings are now all 0% (that change should be enough to remove the stray colors). When it’s right, click OK, and you’ll have solid white in your white areas.

This week Corey has a cool new trick for using 3D reflections in a rather creative way!
If you have a multilayer composition and you
want to apply an effect to all the layers at once, don’t flatten the layers–use a composite layer instead. Hide the layers you want excluded, and press Shift-Command-Option-E (PC: Shift-Ctrl-Alt-E). A new layer will be created at the top containing a merged copy of all the visible layers.
Another option is to create a new layer at the top of the stack and make it active. Command-click (PC: Ctrl-click) each layer you want to include to make those layers active, as well. Press Option-Command-E (PC: Alt-Ctrl-E).
