A great example of the benefits of composing and creating print files using InDesign rather than Photoshop. Besides being a great multipage tool to create print documents, ebooks and other media, InDesign can handle many of the effects that designers commonly use in Photoshop such as gradients, drop shadows, glows, etc. Keep using Photoshop for extreme text effects and photos, but use InDesign for layout, text, text with effects, and color selection.
This short video covers basic backgrounds, basic text and an image and shows how much smaller and efficient your file will be using InDesign instead of Photoshop. Creating a PDF from InDesign will give you sharp vector type, shapes and gradients while doing that in Photoshop will rasterize your type and it won’t print clearly.
