Offset printing, which is also known as offset lithography, is a type of mass production printing in which images on metal plate are offset (transferred) to rollers and rubber blankets and then to the print media. The print media in most cases is paper and is prevented from coming into direct contact with the metal plates, therefore, increasing the longevity of the plates. The rubber used is flexible and easily attaches to the print media surface making it possible to use this process on rough surface material like wood, cloth or canvas. Offset printing is normally the best option in projects that require a large quantity of clean, professional looking and accurate color prints.
What is the difference between offset printing and digital printing?
While digital printing uses toners or large printers that use ink, offset printing uses plates. This is why digital prints normally shine especially if it was done in a low quantity. But digital printing has an advantage over offset printing of providing a unique, address, name and code when required in individual pieces, which is something that cannot be achieved with offset printing. If the business needs runs that are fewer than 500 pieces, his best printing method to use is digital printing.
Advantages of offset printing
- Durable printing plates – the plates used in offset printing technique normally lasts for a long time since the printing plate and the printing surface don’t interact directly.
- Quality Finish – This is the biggest advantage that offset printing has over other types of printing. It produces clear, precise and clean illustrations which all printing jobs. This is mostly due to the fact that the fine layer of the rubber attaches itself to the printing surface.
- Fast when large quantities are required – When large runs of about 500 and more re needed, offset printing is the fastest solution.
Types of offset printing machines
There are basically two main offset printing machines that we use here at Prajapati Advertising. The first one is in-sheet feed offset printing which involves staffing single papers into the machine. The pages can be trimmed after printing or pre-cut to the final publication size.
The second offset printing machine or method is web offset printing. This is where larger and higher-speed machines are used. Large rolls of paper are fed into the machine which is then trimmed or separated after printing has been completed. This type of printing is more popular with small and medium size jobs like limited-edition books.
At Prajapati Advertising, we will discuss with you your unique needs and requirements and decide with you the best printing method that will satisfy those requirements.
