A good collateral or a piece of advertising should answer the questions of the audience to which it is addressed. The design and message should clearly reflect their purpose. Any advertising or marketing's material should be created with an idea, and just an idea in mind ... to invest in quality, that's my first goal in my creative work. If collateral materials are cheap and poorly produced, customers will relate the quality of that piece with the goods or services the company provides.
A satisfied customer is a valuable recognition of my work, and going the extra mile in producing quality pieces is well worth the time and effort.
