I am on a mac and I use the whole creative suite to put my ideas in the computer. I will either start in the computer using Illustrator to draw my idea or I will start with a sketch that I scan into Photoshop. I will then convert my art into bitmaps to bring into Illustrator. If you are working with type, Illustrator and InDesign are the way to go since it is vector based. I will put each plate on it’s own layer to keep things straight so I know how it will print. InDesign is great for multiple page documents and for setting up files 2-up.Hope this helps!Adina
