When a client forces us to use artwork provided by them that is badly compromised we will force them to
sign a waiver prior to production. The waiver is written proof they were warned up front about technical issues with their artwork.
Fake designers have been a problem going back 30+ years to when the graphic design industry shifted from analog production methods to
digital.
One of the first selling points with
computer graphics software: the applications would allow anyone to do the work rather than those pesky, high-priced "professionals" with their degrees and other snotty nonsense.
The firm would save a fortune letting the secretary do the layout work instead, and the computers would get the work done faster!
Back when graphic design was done via paste-up boards, darkrooms, etc any projects required some up front planning, various kinds of acquired technical skills and
discipline to complete. Computers allowed much of that to be thrown right out the window. With computers,
anyone can be an artist! Unfortunately the graphic design field in general has been overrun by a lot of amateurs since then. There is a LOT of terrible quality design coming from people who get paid full time to do that sort of work. And the whole
anyone can be an artist thing has pushed down wage scales. That is causing some people who do have talent to leave the field and find better paying jobs doing something completely different.
In the early days of "desktop publishing" many logos were pieces of vector-based artwork. I kind of blame the mid-late 1990's boom in Internet web design for the plague of pixel-based "logos" we've had to endure ever since. Amateurs were getting hold of pirated versions of Photoshop and using it to pass themselves off as designers. The situation is hardly any better today, even though there is a variety of free/cheap vector-based drawing tools on the market, even for portable devices like the
iPad. Most people just can't (or won't) understand the difference between pixel-based and vector-based artwork.
