NEWS PRODUCTION
News production
An aggregate of printing processes, whose scope and character are determined by the circulation, volume an frequency of publication of the newspaper.
The characteristics of newspaper production, in contrast to other specialized
printing processes, are an operational interdependence between the editors and the
printing office employees, based on a strictly established hourly schedule, and t
he utilization of highly productive equipment to expedite the typesetting, preparation of
engraving plates and matrices, casting of stereotype blocks, printing, and delivery of the newspaper.
PROCESSES OF NEWS PRODUCTION
The process of news production are created by the editorial staff, technical and production workers .
They create a mock-up for imposition Laying out the manuscripts, the original illustrations and
other designs The workers of the typesetting shop of the printing plant
ensure that thereaders check and correct typographical errors on the galley and page proofs,and late news stories, which have come into the editorial office during the course of work on the current issue, are added.
PROCESSES OF NEWS PRODUCTION
Finally designed pages are then signed by the editor for delivery to the press.
The pasteboard matrices are made (impressed) from these news-paper pages; stereotypes—forms used for printing newspapers on rotary press machines—are cast from the matrices.
MEANINGS:
Matrix pasteboard
has highly plastic properties for reproducingall graphic elements and that is sufficiently heat-resistant for many castings ofstereotypes (up to 30 metallic stereotypes from one matrix).
Matrices Theseare made on hydraulic presses that develop a total force of 4-7 mega newtons (400-700 tons-force).
Stereotypes
are then cast fromthese pasteboard matrices. On a modern automatic casting unit, two stereotypes can be cast per minute.

The process of custom printing using plates to transfer images into surfaces like papers is called offset printing
Nowadays, it uses a modern computer-to-plate technique when producing materials on printing surface.
It is called offset because of the process on how inks are transferred to print an image.
The ink is not directly pressed onto the paper; it uses plate cylinder where the image comes. From a metal plate, ink is distributed to an offset cylinder (rubber mat) before it is transferred directly onto the paper through an impression cylinder.
The process is done because the water and ink do not mix.
The image is set on a printing plate. It is dampened by oil-based ink and water using rollers on the printing machine. The created image is transferred to the cylinder and then to the paper.
Benefits from Using an Offset Press to Produce Prints
Commercial quantities. Same quality on all prints. Best suited for economically producing large
volumes of high quality prints in a manner that requires little maintenance
There are four colors used when printing on paper sheets or cardstocks.
The color of cyan, magenta, yellow, and black are mixed to form a final product with good color resolution.
Advantages of offset printing compared to other printing methods include:
Consistent high image quality. Quick and easy production of printing plates. Longer printing plate life than on direct litho
presses because there is no direct contact between the plate and the printing surface.
Cost. A further advantage of offset printing is the
possibility of adjusting the amount of ink on the fountain roller with screw keys.
Disadvantages of offset printing compared to other printing methods include
Slightly inferior image quality compared to rotogravure or photogravure printing.
Propensity for anodized aluminum printing plates to become sensitive (due to chemical oxidation) and print in non-image/background areas when developed plates are not cared for properly.
Time and cost associated with producing plates and printing press setup. As a result, very small quantity printing jobs may now use digital offset machines.
In Industry Offset lithography became the most popular form
of commercial printing from the 1950s ("offset printing"). Substantial investment in the larger presses required for offset lithography was needed, and had an effect on the shape of the printing industry, leading to fewer, larger, printers. The change made a greatly increased use of colour printing possible, as this had previously been much more expensive. Subsequent improvements in plates, inks, and paper have further refined the technology of its superior production speed and plate durability.
Today, lithography is the primary printing technology used in the U.S. and most often as offset lithography.
Today, offset lithography is "responsible for over half of all printing using printing plates". The consistent high quality of the prints and the volume of prints created for their respective cost makes commercial offset lithography very efficient for businesses, especially when many prints must be created.
Odor free offset printing is the newest technology.
