Photo offset
The most common kind of offset printing is derived from photo offset process, which involves using light-sensitive chemicals and photographic techniques to transfer images and type from original materials to printing plates.In current use, original materials may be actual photographic prints and typeset text. However, it’s more common — with the prevalence of computers and digital images — that the source material exists only as data in a digital publishing system.If actual source materials are used, they are assembled in a page layout by “pasting up” the type (text) and images (such as photographs) on heavy paper sheets or boards, referred to as “mechanicals” or “paste-ups.” These are exact representations of the printed page.To produce a printing plate, the layout is photographed using a “copy” or “process” camera, from which a full-size negative film (flexible plastic sheet) is produced.This film, or “page negative” (in which black areas such as text are clear, and white areas such as the background are opaque black) is then placed in contact with an emulsion-coated printing plate. A high-intensity light exposes the printing plate through the negative. After chemical development, the plate is coated with a liquid that sticks to the exposed areas of the plate and dries into an ink-receptive surface. This forms a positive (and “right-reading”) image of the page to be printed.With digital publishing systems, physical paste-ups are replaced by virtual layouts created on a computer, which outputs page negatives or printing plates. If negative film is output, it is used to expose printing plates. In “Direct-to-plate” systems, the printing plate is exposed directly by a computer-driven device.

This article is talking about the most commnon method used to print photos and how to do it. it goes into extreme detail and abotu how what materials are used and hwow they can be changed around. i think itis good knowledge to know but if you are not into it can seem really boring and not worth the read.
Comment by Phillip Bates May 4, 2007 @ 2:12 pmso i don’t really find this article useful… it kind of just repeated itself every other sentence and didn’t really say anymore than three sentences… i mean i can see where the process might be hard and time consuming and that we all want to make it as quick as possible… but make it more interesting…
Comment by Jon Dail May 4, 2007 @ 2:14 pmThis article was very interesting. What I gathered from it was that the most common kind of offset printing is derived from photo offset process, which involves using light-sensitive chemicals and photographic techniques to transfer images and type from original materials to printing plates. This is probably the most basic principle of photography and printing that all graphic designers should be aware of.

Comment by Ryon Swain May 4, 2007 @ 2:15 pmthis article was pretty interseting but i felt like it endorsed the digital printing method over the offset which was kind of wierd because i thought that this article was going to be all about the offset press.
Comment by nancy todd May 4, 2007 @ 2:16 pmIf memory serves me right, there is a certain ingredient in the farm of Kenichi Korita. He uses this ingredient to make bell pepper salad. It is a speciality at his 5 star restaurant known as Taco Bell mansion. Also, his green onions are known to wield special powers to the owner. Come Kenichi Korita, to kitchen stadium, and challenge one of my Iron Chefs to a battle of culinary skill and wit! Allez Cusine! Iron Chef is the best show ever!
Comment by Seth Schattner May 4, 2007 @ 2:16 pmI agree that the photo offset process is the most common and best method of printing. I have personally used the offet method several times and I have to say its quite amazing. It blows my mind. Like honestly that just happened.Im glad someone cares enough to write an excellent article about it.
Comment by Zach Warmouth May 4, 2007 @ 2:17 pmUm this seems more like a photography article than a graphics article. This article is about digital images, and negatives, and film. This doesn’t have too much to do with graphics. I already know most off this stuff from my other class.
Comment by Taylor Hodges May 4, 2007 @ 2:17 pmGiven our recent experience with offset presses, Herzog, I believe they should be boycotted. Just kidding. I do really like your plate printer, though. It makes using the offset about a million times easier.

Comment by steven harkless May 4, 2007 @ 2:19 pmThis article talkes about the most common method of printing photos and how they are done. I thought this article was helpful because i didn’t know some of the stuff in the article.
Comment by Daiki Furuzono May 4, 2007 @ 2:19 pmThis is an interesting article about the process of offset printing. I think it’s crazy how everything analogue and manual is switching to automatic and digital. I like it because it’s convenient but at the same time I think it’s taking away from the artistic value of things. A lot of the art in things come from the creative process and I think by going digital with everything is taking away from that process.
Comment by Tanner Curtis May 4, 2007 @ 2:20 pmThis article is somewhat confusing to me. I think it is very relevant to us. The offset photo process sounds somewhat complicated to me but that is mostly because i’m not very familiar with it. i like how some of the words in the article are red though–it makes it a little easier to understand the terms.
Comment by rachel holtzclaw May 4, 2007 @ 2:20 pmthis seems like a random little article or part of one that says that alot of the time photos only exist in files and not physical life or film as much because of the increase in the digital world including in photography.
Comment by Ashley Thompson May 4, 2007 @ 2:20 pmI honestly think that digital photography should completely replace developing negatives. It is much easier and you can’t make any mistakes in the process like you can using chemicals. Also, you have a backup copy on your computer and camera card.
Comment by Justin Blackburn May 4, 2007 @ 2:22 pmoffset printing rocks alot.
Comment by logan pool May 4, 2007 @ 2:24 pmI didn’t feel like reading this article. It’s Friday, and I’m very tired. I’ll post a better response on the next article.
