The “Blink Test” is where you put something in front of you, blink, then see what you see first when your eyes open. Usually color and bold writing is seen first, what do you see first on your business card?
Obviously different business cards will show different things. For me, I want my name and company name to be seen first. That is why my business card is red, but my name is in a bold white font.
When I do the blink test, I see my name first, just as I want it. This is important because subconsciously this is what people see first when the look at your business card so make it memorable!
