What an absolutely WONDERFUL video! As a young (29) amateur graphic artist with experience in an old family-owned printing company, I greatly enjoyed getting to hear some of the backstory of where the fonts I have taught myself to use came from, and how they were created. Thank you for the time and upload! -Coast of Texas.

Xerox really were the quiet developers behind lots of the computing elements we take for granted these days. In the mid 90's I had the opportunity to help install one of the first Print-On-Demand systems in Ireland using their DocuTech production printers. It was a 15 foot long beast of a machine that could spit out stitched booklets and book bodies ready for binding. All pagination and composition could be carried out via the onboard touch screen, which consisted of a wire mesh overlaid on the monitor. During the training programme at Xerox's Dublin offices our trainer let us into his cluttered little office to see his still functioning Xerox Star. He was _still_ using it in his everyday work and I got to play around with a little. I think our company were operating with Windows for Workgroups 3.11 at the time, and I remember thinking how clunky and quaint the mouse and the desktop environment on his Star were, compared to our superior kit! I wouldn't be at all surprised to find that our trainer, who would be long retired by now, is still using his beloved Star in his study. Well, that's how I'll choose to believe it anyway!

For the past 5 or 6 months I've been fixated on convincing people that this very topic is the coolest thing ever. As expected, said recipients of my rants haven't won too many friends... I guess it's some futile Luddite survivor's guilt from being a severely awkward bookworm who hid out in the public library growing up - who also happened to be on the 'remedial' side of the literacy spectrum...Many many hours spent perfecting 'appearing to be studiously reading' have finally paid off.

Fonts are often owned property, you cant simply hand them out with your game, and you cant assume the user to have that 'cool one you like' installed. so learning the basic concept of fonts can save you development issues, and money. I was programming an LED-type display for a game-hud that works at various resolutions... Managing the whole alpha-bet, numbers, and special charachters, and making them readable in 5*6 LED characters, on scalable LED bulbs (3 to 20 or so pixels, AND look the same on various screen-sizes was something of a learning experience... Issues like minimum pixel-count for each LED, while maintaing the size ratio of the LED-matrix-display to game-screen area... and so on... Scaling things to look good isnt as easy to do as it is to imagine, with all those resolutions, aspect ratios, and so on out there... Lots of numbers arent so easily devidable, but you dont want to do TOO many manual exceptions, so it requires some planning... Which is why: Fonts are often owned property, you cant simply hand them out with your game, and you cant assume the user to have that 'cool one you like' installed. so learning the basic concept of fonts can save you development issues, and money.

Super sampling does not really solve the aliasing problem, but I'll have to save my rant about that... Also, a 300 dpi printout is going to be much lighter and blurrier than it should if you apply super sampling. Hinting creates a sharp image and indeed is your only choice when your device only creates sharp images.

Everyone here is talking about antialiasing as if it's the same problem as here. You might be surprised to learn that modern cg for broadcast tv without using AA runs into the same problem as here but MUCH worse because of screen sizes. AA fixes the problem to some level but because of issues with the depth buffer, it's still often considered unsuitable for most broadcasters.

Very right, 300 dpi looks horrible. And yet, they are trying to tell us that the 200-300 ppi Retina display will be enough for eternity. No it won't! Yes, I am aware of the fact that you can't compare laser printer resolution and screen resolution but 300 dpi ink jet printers also produce horrible text and anti-aliasing is ultimately just a hack. What you want is a 1-bit output with enough pixels so you won't notice it.
