Introduction
Offset printing is a method of printing that has been around since the late 1800s. It was invented by Ira Washington Rubel who was trying to improve lithography for book printing. The process involves using a plate cylinder which has an image of text or pictures on it that gets transferred onto paper when it rubs against a blanket cylinder in an offset press. This allows ink to sit on top of the image area and paper not to be printed there, while water sits everywhere else so that ink will not stick there either (you need both water and ink for this process).
Offset printing was invented in 1904. It's derived from lithographic printing which had been around since the 1700s.
Offset printing was invented in 1904 by Ira Washington Rubel. He was trying to improve lithography for book printing, but he also invented this offset method of printing while doing so. Lithography is a technique that uses a flat stone as the printing plate (or plate) and ink on the surface of the stone transfers to paper when rubbed or soaked with water.
Rubel's invention was meant to be used for commercial reproductions of artwork such as maps, diagrams and drawings where it had been difficult or impossible to transfer an image from one surface onto another using traditional lithographic techniques.
Offset printing presses can print on paper, wood, metal, and plastic.
Offset printing is a type of printing in which the inked image and non-image areas of an image (called a plate) are transferred to a rubber blanket. The ink adheres to the rubber blanket, while the paper or other material being printed is brought against the nonprinting side of the rubber blanket and passed through rollers that press the ink onto it.
The first machines were used in 1798 by Nicolas Robert and Didot in Paris, France. It was invented by Alois Senefelder, who combined woodcuts with metal plates instead of using woodblocks for his prints.
In an offset press, there are four cylinders. The first cylinder (or plate) is where the artwork sits. The second cylinder is the blanket cylinder, which carries that image to the third cylinder - the impression cylinder - which actually makes contact with the paper and transfers it.
When printing on paper, an offset press will use a plate to transfer the image from the plate cylinder to a blanket cylinder, which is in contact with the impression cylinder. The plate and blanket cylinders work together to create an offset print. The plate has two different functions: It carries a negative charge so that it attracts ink on the surface, and it does not have any ink on it so that it can carry water (the opposite of ink). Water molecules are attracted to paper because they share many properties like size and shape; however, since they repel each other when in close proximity, they will naturally flow outward from one another. On top of this unfortunate fact of life for us humans - we need water but don't like being around each other too much - there's even worse news for our inability to get along when working with printers!
To make an offset press work effectively, it requires water and ink. The plate cylinder has a water-receptive surface that attracts water molecules but repels ink molecules. The image area of the plate does not accept water molecules, so it attracts ink molecules instead. When the plate touches the blanket cylinder and then transfers its image to paper, the ink sits on the image area in order to print it, while the water sits everywhere else on that page or material in order to keep it from being printed.

Offset printing is a type of printing that uses a plate that transfers ink to a rubber blanket and then to the paper. Offset printing was invented by John Walter Wilson (1890 – 1960) in 1904 during his employment at The New York Tribune newspaper office under editor Charles Merrill Smith (1866 – 1945). In 1906 he founded Commercial Color Laboratories with his brother Henry E Wilson (1891 - 1980) who later became president of General Aniline & Film Corporation (GAF).

Offset printing was invented by Ira Washington Rubel, a lithographer, in 1904. He was working on improving lithography for book printing. Today, offset printing is used mainly for commercial and industrial purposes rather than the traditional use of creating images onto stone or metal plates using hand-drawn artwork or illustrations.
The history of Ira Washington Rubel
In order to understand the history of offset printing, it's important to know the history of Ira Washington Rubel. He was born in 1871 in Missouri and he had a love for art, science and invention. He was a pioneer in the field of printing because he was the first person to use offset printing, which is still popular today.
Ira invented his own motorized version of letterpress machine that could replicate texts at high speeds by using blocks and moveable type instead of plates as used traditionally by printers. The machine could also print on both sides simultaneously so there was no need for multiple prints or re-inking.
Conclusion
Offset printing has been around for over 100 years. It's a great way to print large amounts of documents quickly, and it offers some advantages over other types of printing. The image quality is higher because there is no pressure involved in the process, so everything looks crisp and clean. The downside of offset printing is that it uses more material than other methods like letterpress or digital printing; but if you need high volume output with low cost per page then offset might be right for you!
