Offset printing is a commonly used printing technique in which the inked image is transferred or "offset" from a plate to a rubber blanket, then to the printing surface. When used in combination with the lithographic process, which is based on the repulsion of oil and water , the offset technique employs a flat planographic image carrier. Ink rollers transfer ink to the image areas of the image carrier, while a water roller applies a water-based film to the non-image areas.
The modern "web" process feeds a large reel of paper through a large press machine in several parts, typically for several metres, which then prints continuously as the paper is fed through. Development of the offset press came in two versions: in by Robert Barclay of England for printing on tin , and in by Ira Washington Rubel of the United States for printing on paper. Lithography was initially created to be an inexpensive method of reproducing artwork.
Tin cans were popular packaging materials in the 19th century, but transfer technologies were required before the lithographic process could be used to print on the tin. The first rotary offset lithographic printing press was created in England and patented in by Robert Barclay. Later, the cardboard covering of the offset cylinder was changed to rubber,  which is still the most commonly used material.
As the 19th century closed and photography became popular, many lithographic firms went out of business. Many printers, including Ira Washington Rubel of New Jersey , were using the low-cost lithograph process to produce copies of photographs and books. The Harris Automatic Press Company also created a similar press around the same time. Charles and Albert Harris modeled their press "on a rotary letter press machine". Newspaper publisher Staley T.
McBrayer invented the Vanguard web offset press for newspaper printing, which he unveiled in in Fort Worth, Texas. One of the important functions in the printing process is prepress production. This stage makes sure that all files are correctly processed in preparation for printing. This includes converting to the proper CMYK color model , finalizing the files, and creating plates for each color of the job to be run on the press.
Offset lithography is one of the most common ways of creating printed materials. A few of its common applications include: newspapers, magazines, brochures, stationery, and books. Compared to other printing methods, offset printing is best suited for economically producing large volumes of high quality prints in a manner that requires little maintenance.
Every printing technology has its own identifying marks, as does offset printing. In text reproduction, the type edges are sharp and have clear outlines. The paper surrounding the ink dots is usually unprinted. The halftone dots can be hexagonal though there are different screening methods. The plates used in offset printing are thin, flexible, and usually larger than the paper size to be printed. Two main materials are used:. Computer-to-plate CTP is a newer technology which replaced computer-to-film CTF technology, and that allows the imaging of metal or polyester plates without the use of film.
By eliminating the stripping, compositing, and traditional plate making processes, CTP altered the printing industry, which led to reduced prepress times, lower costs of labor, and improved print quality. Both technologies have the same characteristics in term of quality and plate durability longer runs. However often the violet CTP systems are cheaper than thermal ones, and thermal CTP systems do not need to be operated under yellow light.
Thermal CTP involves the use of thermal lasers to expose or remove areas of coating while the plate is being imaged. This depends on whether the plate is negative, or positive working. Violet CTP is "based on emulsion tuned to visible light exposure". Another process is computer-to-conventional plate CTCP system in which conventional offset plates can be exposed, making it an economical option.
Sheet-fed refers to individual sheets of paper or rolls being fed into a press via a suction bar that lifts and drops each sheet onto place. A lithographic "litho" for short press uses principles of lithography to apply ink to a printing plate, as explained previously. Sheet-fed litho is commonly used for printing of short-run magazines, brochures, letter headings, and general commercial jobbing printing. In sheet-fed offset, "the printing is carried out on single sheets of paper as they are fed to the press one at a time".
Sheet-fed presses use mechanical registration to relate each sheet to one another to ensure that they are reproduced with the same imagery in the same position on every sheet running through the press.
A perfecting press, also known as a duplex press, is one that can print on both sides of the paper at the same time. Offset duplicators are made for fast and quick printing jobs; printing up to 12, impressions per hour. They are able to print business forms, letterheads, labels, bulletins, postcards, envelopes, folders, reports, and sales literature.
The feeder system is responsible for making sure paper runs through the press correctly. This is where the substrate is loaded and then the system is correctly set up to the certain specifications of the substrate to the press.
The Printing Unit consists of many different systems. The dampening system is used to apply dampening solution to the plates with water rollers. The inking system uses rollers to deliver ink to the plate and blanket cylinders to be transferred to the substrate.
The plate cylinder is where the plates containing all of the imaging are mounted. Finally the blanket and impression cylinders are used to transfer the image to the substrate running through the press. The delivery system is the final destination in the printing process while the paper runs through the press.
Once the paper reaches delivery, it is stacked for the ink to cure in a proper manner. This is the step in which sheets are inspected to make sure they have proper ink density and registration. Production or impact of double image in printing is known as slur. Web-fed refers to the use of rolls or "webs" of paper supplied to the printing press.
Typical examples of web printing include newspapers, newspaper inserts or ads, magazines, direct mail, catalogs, and books. Web-fed presses are divided into two general classes: coldset or non-heatset and heatset offset web presses, the difference being how the inks dry.
Cold web offset printing dries through absorption into the paper, while heatset utilizes drying lamps or heaters to cure or "set" the inks. Heatset presses can print on both coated slick and uncoated papers, while coldset presses are restricted to uncoated paper stock, such as newsprint. Web offset presses are beneficial in long run printing jobs, typically press runs that exceed ten or twenty thousand impressions.
Speed is a determining factor when considering the completion time for press production; some web presses print at speeds of 3, feet meters per minute or faster. In addition to the benefits of speed and quick completion, some web presses have the inline ability to cut, perforate, and fold. This subset of web offset printing uses inks which dry by evaporation in a dryer typically positioned just after the printing units; it is typically done on coated papers, where the ink stays largely on the surface, and gives a glossy high contrast print image after the drying.
As the paper leaves the dryer too hot for the folding and cutting that are typically downstream procedures, a set of "chill rolls" positioned after the dryer lowers the paper temperature and sets the ink. The speed at which the ink dries is a function of dryer temperature and length of time the paper is exposed to this temperature. This type of printing is typically used for magazines, catalogs, inserts, and other medium-to-high volume, medium-to-high quality production runs.
This is also a subset of web offset printing, typically used for lower quality print output. It is typical of newspaper production. In this process, the ink dries by absorption into the underlying paper. A typical coldset configuration is often a series of vertically arranged print units and peripherals. As newspapers seek new markets, which often imply higher quality more gloss, more contrast , they may add a heatset tower with a dryer or use UV ultraviolet based inks which "cure" on the surface by polymerisation rather than by evaporation or absorption.
Sheet-fed presses offer several advantages. Because individual sheets are fed through, a large number of sheet sizes and format sizes can be run through the same press. In addition, waste sheets can be used for make-ready which is the testing process to ensure a quality print run.
This allows for lower cost preparation so that good paper is not wasted while setting up the press, for plates and inks. Waste sheets do bring some disadvantages as often there are dust and offset powder particles that transfer on to the blankets and plate cylinders, creating imperfections on the printed sheet. This method produces the highest quality images. Web-fed presses, on the other hand, are much faster than sheet-fed presses, with speeds up to 80, cut-offs per hour a cut-off is the paper that has been cut off a reel or web on the press; the length of each sheet is equal to the cylinder's circumference.
The speed of web-fed presses makes them ideal for large runs such as newspapers, magazines, and comic books. However, web-fed presses have a fixed cut-off, unlike rotogravure or flexographic presses, which are variable. Offset printing uses inks that, compared to other printing methods, are highly viscous.
There are many types of paste inks available for utilization in offset lithographic printing and each have their own advantages and disadvantages. These include heat-set, cold-set, and energy-curable or EC , such as ultraviolet- or UV- curable, and electron beam- or EB- curable. Heat-set inks are the most common variety and are "set" by applying heat and then rapid cooling to catalyze the curing process. They are used in magazines, catalogs, and inserts.
Cold-set inks are set simply by absorption into non-coated stocks and are generally used for newspapers and books but are also found in insert printing and are the most economical option. Energy-curable inks are the highest-quality offset litho inks and are set by application of light energy. They require specialized equipment such as inter-station curing lamps, and are usually the most expensive type of offset litho ink.
Ink and water balance is an extremely important part of offset printing. If ink and water are not properly balanced, the press operator may end up with many different problems affecting the quality of the finished product, such as emulsification the water overpowering and mixing with the ink.
This leads to scumming, catchup, trapping problems, ink density issues and in extreme cases the ink not properly drying on the paper; resulting in the job being unfit for delivery to the client. With the proper balance, the job will have the correct ink density and should need little further adjustment except for minor ones.
An example would be when the press heats up during normal operation, thus evaporating water at a faster rate. In this case the machinist will gradually increase the water as the press heats up to compensate for the increased evaporation of water.
Printing machinists generally try to use as little water as possible to avoid these problems. Fountain solution is the water-based or "aqueous" component in the lithographic process that moistens the non image area of the plate in order to keep ink from depositing and thus printing.
Historically, fountain solutions were acid-based and made with gum arabic , chromates or phosphates , and magnesium nitrate. Alcohol is added to the water to lower the surface tension and help cool the press a bit so the ink stays stable so it can set and dry fast. While the acid fountain solution has improved in the last several decades, neutral and alkaline fountain solutions have also been developed.
