Print a Calendar in Offset Part 2: Printing

october 2015 calendar print This is a topic that many people are looking for. star-trek-voyager.net is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, star-trek-voyager.net would like to introduce to you Print a Calendar in Offset Part 2: Printing. Following along are instructions in the video below:

“Good morning again guys. It is me again and today. We are doing the actual actual printing of the calendar. So let s do that so before i start with explanation of exactly how these calendars were printed using offset.

I should probably explain just the very basics of what offset is and the room is actually really loud so i m just gonna overlay videos of what we did on top of me talking about what we actually did it s a lot quieter that way firstly. You re gonna see that this is it s a it s called the cd the cd 74. It s a heidelberg cd. 74.

Machine it s a halle berry speed master and it prints up to 10000. Sheets per hour and we are going to use this it s a pretty industrial machine. It s nothing like you would see in any sort of like office environment or any kind of regular environments. Commercial machine.

And you re going to see that it has these things that look like powers and i m going to say them in german because we re gonna learn some german words because i sometimes something english words. I think these in english are called print engines. But in german. They re called the brook bacon and you re gonna see that the machine actually has six different brook bacon and we re only using four of those because we have see my hay which is see on magenta yellow and key for black and pretty much all of the prints all of the prints and offset print are composed of these four colors and different amounts of mixed together dots and the way.

The doctor makes together is also kind of different the other two towers that you ll see those can be used for the first one in this case was actually used to latta machines to give the sheets. The first quake pressed and then the last group that can be used as a lock react..


Which is sort of like a not a non elimination thing. But like rugelach is like a coating like a shiny coating they can be put on top of it to give sort of a general explanation of exactly how the entire printer is arranged this is at the very end of the machine. If we re looking at friday left. And it s called the house vega.

This is where all of the all of the sheets come out this is the c on yellow and these are all of the brooke bacon. And this is the omega and this i m mega uses suction jesus suction cups to pick paper up from a really large crate of paper and it sucks them into the machine and takes them through the book mecca and puts them in the alice vega and inside of these brooklyn decker. You have say. This is one row clamp you ll have like this up here.

Which is like the color. This is this is where the color goes in this is at the top machine that you ll see and then you have patents addendum. Which is where the actual plates that we made in the last video are mounted and and gripped. And they are the basically a bounce around the stone right here and then you have what s called the cometo crescendo.

Which is this sort of elastic material covered metal cylinder on which the actual image goes from the plate to the the paper basically so it goes around this can we talk to the images. And i m the gobi chilled sedona and then you have the actual paper and though of course. It s not completed it would make any sense. And how is the paper going to stay on the coming to upsetting them and then at the very bottom you have a really big gaming group to them and this really quickly.

This is the fob deaq misses the pattinson enough. This is the goomy talk to them them this is the in rope and the job of this bottom cylinder..


Which is super huge and super heavy is to press. The paper against the cometo to linda. And that is actually one part of today s problems that we had to deal with basically the distance right here matters a lot based on the on the paper to your printing and the paper that we were printing had a thickness of 015. Millimeters and it was not very rough.

The our our tutor. Said that it was it was a dream to work with he is kind of a weird to dream from paper. We basically had to adjust the the pressure with which of course if you have this sort of gap. The paper has sort of elastic tendencies and you re going to be depressed with a certain pressure that would actually make a full contact with the paper while getting all the way down into the deepest fibers of the material while also kind of compensating for the bumps of the paper.

Which can you know very and not really millimeters. But micrometer and basically we did that the special thing with this machine was that the go me to sit under doesn t necessarily move up and down or anything. But it can actually swivel around the platen said under like this and in doing that it actually doesn t change the distance between the cotton cylinder and the co. Me talk to them.

But it does change the distance between the gui books it in there and the giggle cylinder and the precision that you re working with there is really crazy we re talking about a tenth of a millimeter. Just for these friends and and this is just awesome that this is only the basic way of how an offset printer works and today. We basically apply what we learned in the first three semesters to print. Our first official job.

That s actually going to be published and used so the first and i m just gonna run through real quickly. The steps that we actually took to make the to use the machine..


The whole morning first we took the plates you had to bend the corner of the plates with a certain tool that would allow the plates to be accepted by the patents. Addendum and two we had to put the plates. I i don t know what it s called an english set the plates i guess on them clapping. I m digging what we had to lay the plates into the machine and then we had to press.

Someone s buttons that would that this this step involves pressing punch buttons and then we had to measure the colors. We would run. We would run a test. We would we would run a test print for a couple of sheets.

And then put that test print into a really really powerful scanner and that powerful scanner would pick up what s called the controllers. But i think on the bulletin. So it s a sort of control element of colors that is always on the sort of edge of paper that you might have seen if you ve ever used in design or anything like that that measured those colors and then using those colors. We would make a sort of adjustments on the actual printer side of the machine.

And that was how we would poof the fob and then we would run another test print and depending on the certain levels that would come out of the machine that we would read with the scanner. We would know if the image was technically correct or not and there were really interesting things like whenever you make an adjustment to the machine for example. If you want to add more color on one certain channel of the paper. Because the paper is actually split up into like 23 of these little channels.

If this is like a paper going in the machine. The the paper split into these little channels..


And if you want to add more ink to one of those channels. It actually takes it there s a certain lag of the machine. Because you know it s just is it s ain t going through rollers that move with a finite speed. And you have there actually the machine can account for this sort of lag.

And what it will do is it will really make an exaggerated color curve and a minke curve that will actually sort of give in a push to the process to make a little bit faster and then it will stabilize back out that was one of the things that we had to cover because we had to make a lot of adjustments and adjustment to the actual image. Because sometimes our images weren t technically perfect. And i thought that was pretty interesting that was new for me and then we were pretty much done after that we would check over the last part was just checking over the the some test prints and letting 700 sheets through or. However many sheets that was i m not really sure it her per run that must have been maybe 200 sheets and then we would categorize them and that was basically like i would call that like finalizing.

The print and we would get a a hand truck and move to move the pallets around and organize all the seats because we actually had a lot of sheets going on i don t think i don t have to think. It s really that complicated to understand the this becomes a lot of it becomes a lot of stuff to understand once you get into like that other printing methods. But this is offset and this was how he printed the calendars and that was that was pretty much it the next video. I will see you guys at be at whatever company that we go to i think is called mu devon teeny.

Where we will figure out how to put the sheets together from the from the sheets that we printed alright see ” ..
