thank you, was searching the whole internet just to find a simple explanation of offset printing (means for really amateurs who never seen an offset printing before) and only this video gave me that explanation. Thanks!
Exactly the same for me, the wikipedia page is meaningless without a prior understanding of the process. I just reread it after watching this concise video and it is still insider nonsense, common problem when people deep inside an industry try to write encyclopedic content.
Thanks a bunch! I came here because I have an infographics exam tomorrow and this video made studying 10x more enjoyable (also faster and more efficient).
@@watupkidd2369 hey mate. I've been a pressman for Over 39 years. In the late 70s and early 80s Heidelberg was the supreme press. Presses were harder to run because lack of technology. Now these days presses are very easy to master because of added componates to water system and auto everything. Sometimes i think there is too much on presses these days.
I had the same experience many years ago. My level of knowledge and experience was minimal compared to the 3-decade pressmen who taught me. They explained things quickly, with the assumption I understood what they meant and had a rudimentary knowledge of the process... uh, process. "OK. Loosen the gearside trolleys on the balloon so we don't get overfeed and smash a blanket if the web wraps." Uh, what? But I didn't have a video that simplified it, though I wish I had.
@@budlewis721 im 35 days into running s offset 1980s akiyama. Just smashed my first blanket Friday:/. Im getting better every day. But mistakes get made and i realize now the buttons are the easy part. Ive never even seen a press before but its fun.
@@L3GENDZLuLKeK It's a long process, even if you're sharp, something I can't claim. Don't ever make the mistake of thinking you have learned enough. There's always more, and you'll never get it all. I'm 69 and retired, and I just learned something I didn't know. I just hope printing will still be a thing in 20 years. And when you do it right, printers will be the only ones that will know.
@@budlewis721 Thanks for taking the time to reply I feel like I’m headed in the right direction, its nice to know my experience is more common then I thought while learning this craft.
I would like to share this video as offset process explainer on our Publisher website. If I would translate it, would you be willing to add the Czech translation in your subtitles please?
Nice, but a brief mention of the alternatives would have been a good addition. Since you mentioned what offset printing is good for, high volume printing, it would be useful to mention what kind of printing might be good when you're dealing with low volume printing, and a link to a video that covers that kind of printing like this one does offset.
Back when we had people do our color separations! We didn't have that tech at our print shops! We had layouts of each pages that were tuned into signatures! We would get our film seps back and hand strip them in! It was very laborious and back breaking! Then we would have to proof everything! Then get approved by client! After that we send to press!
@@fernandovalencia3542 Did you ever use the old flip-top plate burners with the electrode rods that touched to create a light as bright as an arc welder? That smoke _had_ to be toxic.
there is one big mistake at 0:55 the water rollers and the ink rollers are on the wrong place. The blanket always hits the water rollers first then the ink rollers. Look at 0:27. there is the example good. The blanket cylinder turns in the right direction.
Not in a Goss colourliner it doesn't the water roller hits a steel first and another water roller, they are nowhere near the blanket. The water roller goes directly on to the plate.It's just a different setup.
Actually the sheet travelling through the machine is present in wrong way...they are showing that sheet travelles in straight direction... absolutely wrong
Dampening, vegetable oil? I'm sure there's some magic going on here but the video doesn't say what it is. I'm also not sure what the rubber roller is for except maybe it's because metal-paper contact isn't as good as metal-rubber, rubber-paper contact.
If you clean them and put new gumming on the plates, you can use them maybe 1-2 times until the ink accepting layer will get weaker and finally goes off, so there will be no image. We usually destroy them after one time use
You can use them indefinitely, but not for printing (except as noted by HLATG☝above). I once made a Tin Man costume with some and won a costume contest.
If you're printing and want a good black value, don't use 100% K i.e. 0, 0, 0, 100 - it'll be printed looking a bit washed out, or a grey colour. I always use 60, 40, 40, 100 to give a rich black for printing.
I've never seen that, though I'm far from being an authority. Are you sure you weren't laying down too much water to compensate for the excess ink, and washing out the black? In one shop we'd put a deep red underneath the black solids. The result was a black you could dive into, especially on coated stock.
Ok, The rule is Text: 100% Black, rest 0%. When you need a good black on the graphic part, you use rich Black, That's 100%K, 0%Y, 40%C, 40%M... Now, you can make it richer, but it depends on the quality of the offset printing. These are safe numbers. I work for a boardgame manufacturing company and I prepare the files for our costumers.
It isn't necessarily digital. Offset printing can be done using analog techniques. In fact, that is how it was done for decades long before digital graphic design or digital photography came around. This video is slightly misinformation for that reason.
Not in any web printing I've ever done. The lightest color (yelo) is more easily contaminated due to ink on the blankets and idler rollers travelling on the web, especially on long runs. If black was laid down first, you'd spend half the shift shutting down for a washup(s).
The presentation was so simple and the animations made it a lot easier to understand. Thanks❤️
But it’s bull shit

The usual color order is black, cyan, magenta then yellow. I've been a pressman for 39 years.

The water is used to keep the areas of the plate that do not have printing graphics, clean and ink-free
why have i gone down a rabbit hole of typewriters and printing presses
This is a really good video every aspect of it :)
Thanks, this made too much sense 😩

thank you !
Thank you so much
how much dose it cost to make the plates for offset printing? id assume between £250 and £500 ±
Thank you for the info. Blessing in *Christ Jesus.*

Digital or letterpress
@@ginger2770 except barely anyone uses letterpress anymore
@@ginger2770Screen printing is sometimes used as well, although usually on textiles. With the right setup it can work with paper.
Totally understand.

Nice video.. keep up the good work
Muy buena explicación. 👏👍
Excellent video thank
Very helpful thanks
Very nice video
Excellent explanation thank you
Thanks for the video.
Brilliant video
Why is the plate dampened with water ?
Very helpful, thanks!
Offset web press is much better suited for large volume production than sheet fed....
Plus the colors are applied in a different order, as I remember from my days running a Goss Community web press.
How to solve picking problem?
it's great! thank you
Now I'm curious to know how did they do it for newspapers and magazines before the arrival of desktop computers.
Manual press
Back when we had people do our color separations! We didn't have that tech at our print shops! We had layouts of each pages that were tuned into signatures! We would get our film seps back and hand strip them in! It was very laborious and back breaking! Then we would have to proof everything! Then get approved by client! After that we send to press!
@@fernandovalencia3542 Did you ever use the old flip-top plate burners with the electrode rods that touched to create a light as bright as an arc welder? That smoke _had_ to be toxic.
@@budlewis721 sure did!! I remember those cancer causing machines!
Thank you
excellent video, thanks! whats the difference between offset printing and screen printing?
Offset is indirect printing whereas screen printing is a direct printing process done with the aid of a stencil
Sir can you please make a video on how to read a symbols written in machine?
Great video!
Hello, can i use your video for my website
great! thank you
Laser etched plates? Vege based inks? Next you will be telling me that it's all automated?
Please upload more video about printing
there is one big mistake at 0:55 the water rollers and the ink rollers are on the wrong place. The blanket always hits the water rollers first then the ink rollers. Look at 0:27. there is the example good. The blanket cylinder turns in the right direction.

Is offset printing single side?
Yes
Dampening, vegetable oil? I'm sure there's some magic going on here but the video doesn't say what it is. I'm also not sure what the rubber roller is for except maybe it's because metal-paper contact isn't as good as metal-rubber, rubber-paper contact.

Can you reuse the metal printing plates?
If you clean them and put new gumming on the plates, you can use them maybe 1-2 times until the ink accepting layer will get weaker and finally goes off, so there will be no image.
We usually destroy them after one time use
You can use them indefinitely, but not for printing (except as noted by HLATG☝above). I once made a Tin Man costume with some and won a costume contest.
There are three cylender in offset plate cylender, blanket cylender, impression cylender

So much anout this is no right
Wow... this seems very wasteful considering it's how our daily newspapers are printed
Good, but you could stretch this to a 10 minute video and make it more memorable by slowing it down and letting your content breathe.
Black is first, than CMY
Nice Video!
