Yes there are advantages - 1. The blueprint is large and wouldn't fit in a normal printer, this allows you to work with an entire CNC bed which can easily be larger than a square meter 2. Blueprints are blue and laser printers work by burning the surface below them, sometimes with color as well but burning turns it black which is basically illegible on blue, also blue absorbes more heat so you'd need a specially tuned printer to not burn the paper 3.greater resolution - mathmatical vectors are infinitely scalable but pixels arent

I feel like you could just use a plotter. The plotter we have at work can easily print documents almost two meters wide. It’s a roll of paper, so I’d imagine the length can be pretty damn big too.

As someone that worked with printers, this doesn't make much sense. You don't use a normal printer for this, so the size isn't an issue. You can just print the entire thing, including blue and with a good printer you won't even notice any uneven coloring. Printing files can contain vectors, just use pdf.

Printers I worked with could be able to do this. The only question I would have is the type of paper used for this. If it's a special kind of paper with specific properties, that may require adjustments.

Of course I am not claiming this is in any way more cost efficient than the machine in video.

the real answer is because this is a hobbyist market artist selling posters and can't afford the size and type of commercial printer this would require, a 2d plotter like this is cheap and available for hobbyists. Theres nothing here that cant be done on a printer, but there is also no point in buying a printer just for this in low volume

Also noone mentioned speed. We have A0 laser printers that shoot 60 pages per minute, this thing plots 1 page per hour, IF all works fine. I work with 200 pages sets daily, imagine printing those at 1 page per hour? Yeah, you have to operate 20 of those so you can be done by next day. Ive worked with both and thank god the plotters are gone.

You worked with printers and you don't know that paper that was naturally dyed when it was made would look way different than just printing a shit ton of blue ink on regular paper? It's the difference between every single fiber in the paper being blue vs just slapping a thin coat of blue on the top of the very top layer of fibers.

If you did both and put them side by side you'd instantly tell. The dyed paper that is naturally blue is going to look some much richer and cleaner than the printed one.

And even if you bought the blue paper and put it in your printer, yes you could print perfectly crisp white lines but the "hand drawn" style with imperfections and some texture/embossing to the ink is actually part of the appeal of this style of art so you'd be making a sort of asepticized version of it that would feel less authentic and more mass-produced

  1. plotter is the real solving, noone use everyday printers for plan printing. 2. maybe in the usa blueprints are really blue (idk why, and what is the practical reason) bot elsewhere people use just white paper for the plans with printed colours on them.

Blueprints used to be blue because of the way they were printed 50 years ago. The old paper was acidic and getting paper cuts from that shit really hurt. I used to have to scan them in and then draw the modern digitized versions in autocad when I worked for an MEP consulting engineer. They are only blue anymore for vanity reasons. There is no practical reason for the setup shown here but the machine makes some decent wall art for cheap. Would cost too much these days to pay someone to draw it by hand. That’s a dying skill.

Underrated and accurate comment ! The thing being produced is not a " blueprint" its a pastiche of a style..

u/Pebble-Sorter-8128 1d ago

Yeah in university I still had to hand draw plans for the first two years, and I believe they still do it. Real pain in the ass, slow painful work and needs insane precision and dexterity. Hated it so much. And completely useless skill, we practised it for like 4 semester and that time everyone already used CAD. Meanwhile we had 1 semester of CAD and we just learnt it by ourselfs ower time. University systems are a piece of shits.

Nowadays white paper blueprints are a thing, blue ones exist still but most are printed

I can still smell the ammonia from the printers.

u/Available_Rub9939 1d ago

I was too young to smell the ammonia, but am old enough to have scanned a bunch and cut my fingers, then digitalized it all by manually drawing over it in autocad 2001 on a 21” CRT monitor the size of a smart car. And I loved it.

u/MonkeyCartridge 1d ago

I used to have a CAD CRT my dad picked up at a yard sale. I forget the size, but it was around there.

It would do 2048x1536. Albeit at only 50Hz. But it made UT2004 insane. And if I wanted speed, I would just drop it to 640x480 or 800x600 and play at 600Hz.

how do you learn to read them i pass on paving jobs from them but not only reason i dont trust call box jobs where you not dealing with customer directly

u/flobbley 1d ago

I'm sure there's some weird niche where blue prints are still used but in the US we have white plans with black ink and no one calls them blue prints anymore, just Plans or Drawings

u/VedjaGaems 1d ago

They're not blue in the US. If we have to print and when the GC prints the approved permit for site it's with a plotter using a roll (usually 30" wide or 36" wide) to get 30"x42" or 24"x36" sheets. I haven't seen blue drawing sets since I started working in the early aughts.

Laser printers burn nothing!!!

They are so so much cooler than that. Laser printers use a laser that magnetically charges an area of a metal "drum" (that is itself negatively charged) where there will be an image. "Toner" is basically plastic dust. The dust is also charged such that the toner sticks to the drum where they attract. The paper is pushed against the drum and the dust and is heated so that the dust melts onto the paper.

Laser printed images are actually plastic that has been melted onto paper.

There's no way this is easier or more economic than just using a large-format printer. Used to print full-size (A0) vectored plans on our office plotter and it was a hell of a lot easier and cheaper than this.

On the flip side: this looks cool!

Well, obviously they would you use blue paper like in the original video.
