How offset printing happens – a brief introduction on offset printing consumables!

Are you into the printing business? Then you must have a thorough idea about how all of the various kinds of printing take place. And when it is printing that is being talked about, offset is most popular and widely used for every commercial purpose. When you read something like a newspaper, a story book or a magazine, do you ever stop and think how that publication came to existence. It is not the writer or editor, who takes all the pain of bringing an idea to words. The printers too are involved in this process, where they have to use various offset printing consumables to make printing happen.

What is involved?

Offset it one of those technologies that has been into existence for more than a few decades. Although many other advanced printing technologies have evolved in the mean time, offset still is the most trusted and most used printing option that printers trust, when it comes to bulk productions. But before you get the final product ready, there are quite some factors associated with this.

Offset printing involves huge pounds of rolls of paper as it is always meant for bulk printing, wash up blades, rubber rollers, plates and specific chemicals and inks for the print to be done. When a graphic design is made, it is first transferred into a film negative. This film negative is then used to make the metal plates that will do the task of transferring the texts and images onto the paper.

What is the process?

When paper is fed into a printing machine, metal plates are washed with ink and water. The ink gets bound to the design on these plates and water gets to the white portion of paper. With the ink, oil is mixed. This is done in order to make sure that the ink does not get dissolved with the water; but repels due to the presence of oil. It is very important to mention at this point that the ink that is used in this entire process is of high quality and of quite a different texture. It is the most crucial elements of the offset printing consumables.

Usually there are numbers of plates used to transfer colours to the rollers or blankets and then onto the paper that is being used for printing. In case there are four colours being used, there will be four plates like cyan, yellow, magenta and black. These plates offset or transfer that design to those blankets or rollers and then they are printed on paper.
After the wash up blades, rollers and cylinders have performed their task the papers, which are wet are taken to dry up. But in this entire process, it is imperative that you choose high quality equipment and machine parts made up of either rubber-metal, plastic or poly-urethane. For smooth and perfect finish, using blades with sharp and straight wiping edge is very crucial.
