Full Frame vs. APS-C

I've had more than 1 art teacher at my school tell me that 150 dpi is
the max most digital printers print at. I always thought 300dpi was
the golden rule.

But I have been printing a number of publications with commercial printer at 300ppi. In fact, 150ppi is the minimum (not the maximum) resolution most commercial printers will accept your design. You can verify what I said by searching the internet for any commercial printer or any digital designer website.

Photo printing for commercial, which require higher quality and sharpness than magazine, are usually printed at 450ppi or more.

And if you look for any digital printer specs nowaday, they will tell you their resolution is at least 1200dpi for BW printing and 600dpi for colour printing. But their dpi is often misleading for marketing purpose. They use a few dots of different colors to create a pixel.

If you need further verification, you can get photoshop installed and create a new file by choosing any standard printing size. Photoshop will set the resolution and dimension for you.

this is what i've been told. I always assumed more was needed but they insist "if you'r printing digitally nothing over 150 DPI is needed". That's all. I know it was kinda off topic but i thought it was a point worth making cause printing was mention earlier.

I see. This shows that teachers are not always correct perhaps.

Or it is possible that their industrial experience is in different field of art designs. For example, it is perfectly OK to print advertisement banners at 80 dpi or even lower as these are something to view from far. There is no reason one will view a large banners from a distance of reading magazine or flipping your photo album. Then you try to walk close to a big banner, you might even find that a pixel is as large as a few mm x mm.

In this case, a banner designer that never design for magazine will have quite different view in printing resolution. For him/her, it might be true that maximum is 150 DPI.
