yes, absolutely same... cuma offset lebih kepada proses pemindahan imej. manakala kaedah kerja cetakan tersebut dipanggil litografik (lithography)

Who developed the offset lithographic printing process?
At the end of the 18th century, the German printer Aloys Senefelder developed lithography, a planographic technique of transferring images from a specially prepared surface of stone. Taken from Britannica.com
What is meant by the term offset printing?
It is an indirect printing method, hence the term offset. The image is first transferred from the metal plate to a rubber blanket, and then from there to the printing surface. It is one of the better printing methods and fairly cost effective.Offset printing was discovered by accident. They were using a rotary lithographic press and forgot to load it. When the operator loaded it next, he realized the resulting image was clearer when printed from the roller side.For smaller jobs, digital offset may be more cost effective, since you don't have the preparation costs, but it is a more expensive method for larger number of copies than standard offset printing. Rotogravure or photogravure gives slightly better quality than offset, but those are not cost effective until you get into hundreds of thousands of copies.
What are the advantages and disadvantages of offset lithography printing?
Consistent high image quality.Offset printing produces sharp and clean images and type more easily than letterpress printing because the rubber blanket conforms to the texture of the printing surface.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.Properly developed plates running in conjunction with optimized inks and fountain solution may exceed run lengths of a million impressions.Cost. Offset printing is the cheapest method to produce high quality printing in commercial printing quantities.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. This makes smaller quantity printing jobs impractical. As a result, smaller printing jobs are now moving to digital offset machines.
What is a printing plate?
Printing processes such as offset printing use printing plates to transfer an image to paper or other substrates. The plates may be made of metal, plastic, rubber, paper, and other materials. The image is put on the printing plates using photomechanical, photochemical, or laser engraving processes. The image may be positive or negative. http://www.ezeeprinting.com/page/pulpboard-coasters

What is offset lithographic prinitng?
Offset printing is a type of lithographic printing. It uses the principle of the immiscibility of oil and water and takes its name from the blanket cylinder as an intermediate carrier for indirect printing. At present, among various printing technologies, offset printing still occupies a major position, and will continue to develop in the direction of high precision, high quality, high speed, multi-color group, multi-function, and high automatic control level.
What is the NAICS code for lithographic printing?
NAICS Code(s) 323110 (Commercial Lithographic Printing)
What print technology is used to make magazines?
For Magazine printing, Offset printing technology used.Offset printing is a widely used printing technique where 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 on which the image to be printed obtains ink from ink rollers, while the non-printing area attracts a film of water, keeping the non-printing areas ink-free.Currently, most books and newspapers are printed using the technique of offset lithography.

What is offset printing blanket?
Offset printing or web offset printing is a commonly used printing technique in which the inked image is transferred, offset. This is done from a plate to a rubber blanket, then to the printing surface.

Is digital printing less expensive than offset printing?
It depends on your printing needs.Digital printing is more cost effective for short run, custom, or one time projects. Or if you plan to make changes on a regular basis.If you will be printing large quantities of the same design on a regular basis (EX: Flyers, letterhead, folders) then offset printing is cheaper.Gang run printing is a method used by some printing companies. They use a common printing sheet in an effort to reduce printing costs and paper waste. This process makes offset printing less expensive.
What is the concept of lithographic printing about?
Lithographic printing is a method of printing based on the principle that oil and water do not mix. An image is created on a flat surface, typically a metal plate, with a greasy substance. This plate is then inked and transferred onto a rubber blanket or directly onto the printing surface. The areas with the greasy image attract the ink, while the non-image areas repel the ink. This allows for high-quality and consistent reproduction of images and text.
