Flattening a layered image
As you''ve done in previous lessons of this book, you''ll now flatten the layered image. When you flatten a file, all layers are merged into a single background, greatly reducing the size of the file. If you plan to send a file out for proofs, it''s a good idea to save two versions of the fileone containing all the layers so that you can edit the file if necessary, and one flattened version to send to the print shop.
1. First, note the values in the lower left corner of the image or application window. If the display does not show the file size (such as "Doc: 909K/6.4M"), click the arrow and choose Show > Document Sizes.The first number is the printing size of the image, which is about the size that the saved, flattened file would be in Adobe Photoshop format. The number on the right indicates the approximate document size of the file as it is now, including layers and channels.
