In a deeper understanding of offset printing, the following steps, such as offset printing. 

Phase 1 – Pre-Press Production 

This process requires that all documents are placed on plates. In this step, two options are involved in the process. 

Older systems are negative films, which are largely created from digital files to an imagesetter. Negative images transferred to offset printing ink plates largely Similarly, the photographs are developed. The lights are used to measure so that through the negative film to expose the printing plate. When the plates are exposed to light causes a chemical reaction that may be receptive to ink on. E 'became clear, then transfer the image from the negative plate. 

The most recent – the difference at this stage, the old system is that it is left with the film, and stage boardsbe obtained directly from the image of improved fastening systems. The application of paint should be a side pot, and when they need the full-color photos, which uses four colors – cyan, magenta, yellow and black. 

Step 2 – The printing operation 

In this step, the printing inks used to generate the most articles of printed paper for printing is done with offset printing presses. A very thin layer for the use of offset printing is the high-speed printing and may have good useSheet of paper. 

Quadricromia 

As already mentioned, the basic principle of offset printing is that ink and water do not mix. The colors are distributed evenly between the plates through a series of functions. In the press, the plates are paper rolls moistened with water first. The rollers distribute the ink-wells plates.
