Let's get this straight. I think we're using the same words, but thinking of different machines/equipment.
When I refer to a flatbed printer, it's a UV printer carrying 6 colors with it. It has nothing to do with screen printing, other than it essentially takes its place as newer technology on quite a few substrates. It still prints flat stock and not textiles, but it can print onto virtually any FLAT substrate, up to about 2 inches or so in in thickness.
So, in this case, there are no screens to prepare, no burning, no reclaiming, no smelly inks to mix, no squeegees to push/pull back and forth, no snap to worry about, no flooding necessary, no clogging or cleaning and no mess afterwards to clean up. Think of it as a desktop printer for your
computer on steroids. The inks goes down, just like it was coming out of your desk top, just louder and bigger.
With this technology, if someone wants a 4' x 8'
sign on 2 sides, I put the 4 x 8 right on the printer, it prints it at basically the same speed for one color or 16 million colors. And as soon as it's done, I can flip it over and print the other side. And guess what....... ?? Nothing to clean up. You be done. 2-sided 4x8 in about 1/2 hour or whatever speed your machine is. It's the cat's meow, but you hafta be careful what manufacturer you buy. Some really are better than others in certain areas. You need to know what you want to do and buy the right machine accordingly.
