【Preface】 Illustrator was born as a tool for designing PostScript fonts. Since its release as a standalone graphic software, it has repeatedly enhanced its functions, and the latest version, CC 2017, marks its 21st version overall. Over the 20 years since its release, computers have evolved from expensive and specialized machines to something more familiar, and the internet, which emerged alongside them, has grown into something entirely new and different from existing media. Originally created for the printing industry, Illustrator is now used by many users for creating web graphics. In line with the times, Illustrator has added features that are conscious of web production trends and features that support new devices such as tablets, and it may seem like an outdated application. However, when considering why Illustrator is accepted and used by many professionals in the turbulent IT field, I believe the biggest reason is that it is a tool that allows you to "draw as you imagine." Illustrator has many features, but at its core is the drawing of paths using Bézier curves. If you master path manipulation, you will understand that the many features are there to streamline transformations and editing, and you will find that it is a surprisingly easy-to-use application. This book explains most of Illustrator's features in an easy-to-understand manner using illustrations, including the new features of CC 2017. You don't need to read it from beginning to end and master all the features, but I recommend that you at least briefly look through all the pages. You can do it when you have time. By doing so, you will find features and ways of using the software that you didn't know before. A little difference in knowledge can affect how easy Illustrator is to use. And it will lead to a significant increase in work efficiency. I hope this book can help you master Illustrator, even just a little.
