Official Adobe Print Publishing Guide explores the processes and issues involved in preparing color publications for reproduction on a commercial printing press -- a set of tasks known as the prepress process. Such tasks, previously only performed by skilled professionals, can now be accomplished by a wider range of people using the desktop. This book introduces the flexibility and direct control offered by this new technology and outlines the issues involved in preparing electronic files for commercial printing. It also gives information on when to perform a prepress task and when it is better to leave it in the hands of a prepress professional.
