As a designer chances are one of your weaknesses is the "details". As artists we tend to look at the big picture. The details get lost somewhere in our need to be expressive and let "it all out"! Unfortunately, not paying attention to the details is one of the fastest way to lose a client. It only takes one print job that gets cut off, or messed up for you to lose good business. So how can we avoid this? 1. Use templates. Hang on now. When I say templates I do not mean for the design but rather for the document setup. For each printer I use I have a folder on my machine filled with Photoshop, indesign and illustrator documents that include the bleed settings and trim sizes. By doing this, not only do I insure that my designs will be the right size but additionally it saves me the time of gathering specs for every basic job. 2. Use master files. I've said it before but it bears repeating. When working with a file that contains multiple pages take advantage of the master file feature in InDesign. By using those master pages you can easily set up running heads ( the chapter titles that appear on the top of each page) that will be uniform, consistent and best of all quick!! Again keep in mind that paying attention to the details DOES not mean that your design time will be increased. 3. Know your color space. One of the biggest issues I see with student designers work is print files that are built as RGB files and web files built in CMYK. When this occurs they are often upset with the quality of the end result when the price is finalized. Pay close attention to your colorspace. If you need to use a filter that is only available in RGB you can convert using the option " do not merge", add your filter and then convert back to CMYK. As you do this you may realize that the RGB version appears more vibrant. You're right. It does BECAUSE YOU ARE VIEWING IT ON A SCREEN. Avoid the temptation to assume that those colors will print properly.
