It's not easy being a Print Designer. Graphic Design for Print is a complicated process of steps. Ink colors need to be set up correctly in digital files for them to separate correctly on press. Images must be saved in the proper format for prepress departments to output the colors you expect. Fonts must be supplied to the printer and they must be supported by their software. Printing presses can't always achieve the same colors you see on your computer screen, so you need and experienced Graphic Designer who knows what to expect.
I know the print process and the limitations of CMYK. I have solutions for the challenges that stop other designers in their tracks. I personally oversee every step of the printed materials I create and I treat every project like it's my own. I insist on press checks, to be sure the quality of the images and colors are as you expect them to be. The more successful your printed piece, the more successful you look, the better your ROI.
