Known for its flexibility and adaptability, offset printing is the most common direct printing technique today. Liked by professionals, this technique is based on the water - oil repulsion principle. It offers a wide range of products.
Technically, how does offset printing work ? There are two main processes of offset printing : conventional “wet’ printing process and “waterless” printing process.
Historically, this process comes form lithography. The printing process is based on the principle of water - oil repulsion ; In other words, water and oil cannot mix : it makes an emulsion between the moistening solution and the oil ink.
An offset printing takes place this way, step by step :
When everything is ready, the machines are turned on and the printing process is started.
The plate and paper carry on in the following press for a new color. After having been through all the presses, there’s only drying step left ! The paper is then dried with hot air and piled before being sent !
Waterless offset printing use the same principles as conventional offset printing, the only major difference being it doesn’t use water ! There is no moistering system : water is replaced by silicone to avoid the inking of the plate.
As told above, offset printing can be used for a wide range of products. Among which can be found the production of newspapers, books, catalogs, banknotes, screen-printed transfers etc. More generally, several different matters can be treated : cardboard, paper, plastic, metal, etc.
At PrintMyTransfer, we use it for printing our screen-printed transfers !
