How do Offset Printing companies work without a huge investment?
Well, an offset printing company has designed it for commercial use. It slightly lacks in quality when it comes to comparison with rotogravure printing or photo printing. However, it is still in demand with a business producing books and stationery, leaflets, brochures, magazines, and cards in bulk. Let’s get to know how it works? First, we’ll talk about the simple and profitable machinery regarding offset lithography.
The offset printer consists of three cylinders:
- Plate cylinder
- Offset blanket cylinder
- Impression cylinder
Well, let’s start the process. The first cylinder in the offset printer is ‘plate.’ The thin cylinder (plate) has an aluminum coating. Well, it would print the images by attracting the ink and repelling the water. When the plate spins, it will make contact with the rollers to draw ink and repel water.
The second cylinder has named ‘Offset blanket’ as the cylinder has a rubber blanket around it while turning in the opposite direction to the plate. When the machine turns on, both cylinders roll against each other. The squeezing of ink creates a mirror image. Both imagery and non-image sides are simultaneously getting printed on the same flat surface.
The last and third cylinder is an ‘impression cylinder’ made up of clean steel. It will take the couple in the opposite direction to the blanket cylinder. Each revolution of the cylinder dampens the non-image area of the plate with water from the damping system. The primary purpose of the rubber blanket and impression cylinder is to transfer the ink onto the paper.
We can comprehend that the separate cylinders have a fundamental role in the offset printer. Each has its own significance, function, and importance; we can not overlook it.
Once the paper has passed between the blanket cylinder and impression cylinder, it receives the printing image before passing it to the next unit to receive color. It is where CMYK plays an integral role in printing. There is a specific technique to put the substrate into the machine. During the CMYK technique, the cyan and magenta would go hand in hand. After this, the first black has applied, as it can kill the yellow color’s visibility spread over the yellow. After the paper has traveled through each unit, it is almost ready to go.
Piling and cutting
Once the print is almost ready, it is piled at the end with a thin layer of powder sprinkling on it, separating each paper from the other despite damaging the printed image—the next step in marking the page above and below. After the marking, the paper goes into the cutting machine. Now, you can perceive how a giant offset printer works efficiently.
