Offset printing permits you to create huge quantities of printed materials at inexpensive prices. It is a great choice for small and large runs. Despite the affordable price, it produces very high quality images sacrifice quality.
Offset printing is the dominant industrial printing technique, used for printing a wide assortment of products like business cards, catalogs, leaflets, brochures, magazines, and publications. It may also be used for packaging, such as boxes, product packaging or carton. Because of its ability to make commercial amounts of prints with premium quality outcome and inexpensive manufacturing cost, offset printing is a great option for large quantities of printing projects. As a sort of old type print creation, offset printing is still utilized regardless of other modern type of printing technique.
How offset printing works?
Offset printing functions in a very simple manner. It utilizes three cylinders to move the image on the substrate. The first cylinder is mounted using the printing plate. The image on the printing plate is 'right' written or reading with the ideal side up. The first cylinder is inked and the image transferred or offset onto the next cylinder, which can be mounted using a rubber blanket. The picture on the next cylinder is thus reversed or becomes 'incorrect' or mirrored reading. Finally the image is moved from the blanket cylinder on the next cylinder or the substrate. The substrate is mounted on the next cylinder also called the impression cylinder. The picture once more is reversed and becomes 'right' reading or right side up from the final published version.
The entire name of the offset printing procedure is offset lithography. Both terms each describe part of the process: Lithography is a printing process in which the image area and the non-image area co-exist on precisely the exact same plane. That means the surface from which you print is completely horizontal. This is feasible because of a very useful chemical rule: offset printing ink is an oily substance, which means it repels water. If you can produce a surface on which some parts have a thin layer of water, then those regions will repel ink. The picture areas need be lipo-philic (accept ink) while the non-printing regions will need to be hydrophilic (they are repellent to oil and receptive to water).
Offset refers to how the image is not moved from a lithographic printing plate into a sheet of paper. Rather the inked image is transferred (or offset) in the printing surface to a rubber blanket and then to the printing surface. The process can be used to publish on paper, cardboard, plastic or other materials, but these need to get a flat surface.
Is offset printing expensive?
The offset printing process requires a fairly investment in equipment and set up, however, once the infrastructure is in place, offset printing itself is comparatively inexpensive. It is mostly used in producing personal, commercial and small business products. It is perfect for small jobs that must be done quickly. It is the oldest printing technique that printing companies have adopted, yet all printing companies offer offset printing today as an option. In comparison to other printing procedures, offset printing is most appropriate for economically producing massive volumes of top quality prints in a fashion that requires very little maintenance.
Offset printing also permits for more material alternatives. No doubt, it uses an additional step but it gives the producers lot of flexibility in terms of color options. Offset printing has become the most inexpensive printing method to create rather high quality printing in commercial printing quantities.
Advantages of offset printing
- The main benefit of offset printing is its own high and consistent picture quality
- The least expensive method to make superior printing in commercial quantities.
- Because offset presses can print so quickly your offset cost per piece isn't static -- it reduces with volume. Therefore, for large runs offset printing becomes a lot more economical than digital printing since your installation fee is consumed by the reduced cost per piece.
- Larger Runs; a printing volume of over 1000 units is typically ideal for offset printing.
- Larger Format; for instance, a 40″ press can accommodate a level page dimensions of approx. 25″ x 38″.
- Specialized Colors & Techniques; offset presses can print PMS colors and use gloss/matt varnishes for extra texture. Furthermore, multiple media "heads" allow for an unlimited variety of colors and printing methods.
