Most companies need a printing service on a regular basis, whether it is for promotional purposes or intra-company communication. Offset printing is the most commonly used printing technology and knowing about it is therefore helpful and essential.
Offset printing can produce a large number of prints quickly, which makes it more economical than other technologies and also more well known. This is the reason good printing service providers suggest the use of offset printing for bulk prints.
Offset printing uses oil based ink, which does not mix with water. The offset printing is so called because the designs are transmitted in an indirect way from the plates to the paper by use of rubber blankets as the medium.
The process starts by preparing the designs. Film negatives were used in the past for making images and then copying them to aluminum based printing plates. However, a modern printing company would now prepare the plates directly by using an image setting system. This plate is then put on a cylinder in the proper configuration. Next, the water is dispersed on the image plates, which is followed by the ink. The image receives the ink while the rest of the area gets a thin layer of water, which ensures that the ink does not spread outside the images.
Next, the image is inverted when it is put on to a rubber blanket which is stuck to another cylinder. The image is now printed with its correct side looking up by cutting sheets of papers into appropriate size and placing them on a third cylinder.
The job of printing is completed by the printing company by consolidating the printed sheets using staples or glue or in any other way as per the needs of the client.
