I work in a copy-print center where we take orders for business card, posters, flyers, invitations, and all sorts like that. Lately, I have been getting more and more AI generated artwork for these flyers and business cards, and they are not sized correctly. I can tell it's AI generated not from style, layout, or even hallucinations, but just the size. The background are a full color, the customer insists that it's the right size, but I have to tell them that if I print what they gave me, there is going to be large white borders on the sides, tops, or all around. I have had to explain to too many customers that AI doesn't know what an inch really is, as the reference images it has are different sizes. AI flyers could be the best design ever, but it will never be sized properly and will still piss off the print employee.
And I have found that if you are paying for an AI service to get these generic, wrong sized designs, you could have spent just as much going on Fiverr and gotten something that doesn't need to get a full style revision.
