Greetings! I have designed, produced, and installed vehicle graphics for 19 years, with a long line of happy customers.
I know that Vehicle graphics require an outstanding look, but also need to be production friendly - not overly wasting material, not putting text through body moulding, seams, and the like, where it would affect readability.
I've worked with TheBadWrap templates, as well as Pro Vehicle Outlines. I use Adobe Illustrator and Photoshop CC 2014 for the work - although if FlexiSIGN is the software of choice in your shop, I can secure a subscription with a guaranteed need for that program.
I'll look forward to a Design interview with you first, where I can receive the templates you mentioned and get a feel for the company you're designing for, the elements you'll provide, and the look you want. I'd like to get as specific as possible so we don't waste each other's time with 4 or 5 concepts before we get the right look. If you have ideas for the look, a quick search on your part through Google Images for "I like this style" is a big help. Not for me to copy, just for the feel.
Please feel free to contact me for questions!
