In the modern world of printing, the most popular are two methods of printing – digital, offset. Despite the active introduction and distribution of the first, the second is still quite popular, especially in the world of advertising printing. Its essence lies in the transfer of the image onto paper through an intermediary, which is the offset shafts. Off set in English means “without contact with the form”, and this best reflects the whole process: the image is applied to a layer of a photosensitive form for printing, then the design is transferred to an offset roller and only then to the final paper carrier.
Offset printing: features and capabilities
The world became familiar with offset printing services at the end of the 18th century. In 1796, the German actor Senefelder invented an indirect print using stone plates. In the process of evolution, the plates became metal, and then rubber. The latter provided very clear, bright, beautiful and rich colors. For the early 20th century, the images looked very decent.
The first offset printing press was very bulky. Several people were required to service it. And today, when placing an order for offset printing, customers can count on fast and decent execution. Materials coming out of modern equipment are of high quality and color rendering.
There are several classifications of offset printing. By the type of application of coloring materials there are:
- Wet offset is a traditional technology that uses dampening solutions to repel paint in desired areas. Thus, spaces between words, signs, symbols are reproduced.
- Dry offset is a simplified technology that uses silicone instead of a dampening solution. To work with such raw data, a paint with a special composition is required.
Offset printing – the price of creating materials of any format. Exists:
- Narrow-format equipment – for the production of flyers, booklets, labels and other small printing with a sheet width of no more than 60 cm.
- Full-size – used for printing packaging, periodicals, books, catalogs, brochures. The maximum web width is 102 cm. Folding devices allow you to print on two rolls of paper at the same time.
- Large format – billboards, maps, posters, wall calendars and other large format printing products come out of this equipment. Fast offset printing of large formats with a sheet width of up to 190 cm is relevant for large runs of large formats.
Another division is by the type of printing equipment. It can be sheet or role-based. In the first case, the device uses separate sheets of paper, and in the second, whole rolls, on which the image is applied. Subsequently, such rolls are cut into sheets and folded as needed. This kind of offset printing is much more convenient and faster, the price of which, however, is much higher.
What products are offset printing?
The main advantage of offset is that you can use paper of absolutely any type and format, without limiting yourself in post-printing. In advertising printing, offset printing is most often used, the cost of which is more than profitable in the manufacture of large circulations. The larger the number of units in a set, the lower the price for one unit will be.
Almost all printing that surrounds us on a daily basis is made using offset. Calendars, leaflets, magazines, posters, tickets, tags, banknotes are offset printed. It is especially advantageous to order the printing of handouts. It is designed for one-time use, so there is no point in spending large amounts on printing. At the same time, in order to fulfill its task and interest the audience, printing must be beautiful, bright and high-quality. Color offset printing fully copes with these tasks.
Given the wide capabilities of the equipment, it is easier to list what is beyond his ability. These are printing on colored paper with white ink, transferring pictures to methylated paper and film, as well as printing with ultraviolet and folium inks. There are also some restrictions on density – up to 200 g / m2 for roll-up models and up to 420 g / m2 for sheet models.
