What are the advantages and disadvantages of offset lithography printing?
Andreia12
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.

Is lithographic and offset printing the same?
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 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

How does offset lithography work?
Offset printing is where an inked image is presed to two surfaces before it is printed.
What is lithography used for?

What is litho in stamp collecting?
Litho in stamp collecting refers to the printing process called offset lithography.
What are the disadvantages of Lithography?
preparation times are particularly long, particularly in high quality applications.it is financially impractical for the production of a single item, particularly for colour printing advertising applications.
What are 5 different types if print?

Who invented offset printing and when?
Offset printing was invented by Ira Rubel in 1904. He discovered that he could obtain a clearer image by wrapping a rubber blanket around the printing cylinder and transferring the image from plate to blanket before printing on paper.
What is talio chrome?
Talio-Chrome is a trade name for a printing process using halftime dots. It appears to have been a form of offset-lithography or gravure.
What is digital offset printing?
There are many advantages. With digital offset printing, there is consistent high quality, quick and easy production of printing plates, longer printing plate life, and the cheapest printing method out there. However, also be aware of the disadvantages!
Who invented offset lithography?
I think is was: Robert Barclay
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.
