The Right Tool for the Job
Yes, there was a time when I used Microsoft Word to create a printable like everyone else. Then I graduated to Adobe Photoshop, then Illustrator, and others. Finally, I found Adobe InDesign. Your graphic designer should have an understanding of when to use Word, when to use Photoshop, when to use Illustrator, and when to use InDesign, which is specifically for desktop publishing. If your work ever needs to go to a publisher, that printer is going to expect to see it using industry standard design software.
I do invest $50 a month into using the Adobe Creative Cloud suite. This ensures that I have access to all of the industry standard design software and that they are up to date, allowing me to easily transfer my design files to another professional designer if needed.
