Offset Printing: Get to know the advantages of this method in depth


To speak of offset printing is to refer to a reproduction system that has more than a century of history. It has its origins in lithographic principles. It was the work developed by the Englishman Robert Barclay in 1875, and the American Washington Rubel in 1903, who was in charge of laying the foundations of this efficient system.

Of course, a lot of ink has flowed from those early prototypes to now. Digital technology has been incorporated and increasingly efficient machines, tools and accessories have been developed, capable of meeting the needs of customers who handle a large volume of copies and demand quality, efficiency and profitability.

What is offset printing?

There are several aspects capable of distinguishing the characteristics of this precious system: the sharpness of the reproduction is of professional quality; It is a system known for its efficiency, as it guarantees the creation of a considerable volume of copies in the shortest possible time, without diminishing excellence; and it is versatile, adapting to multiple formats and substrates.

The offset method in printing is characterized by the use of the indirect system, in which the plate has no contact with the substrate. Quite the contrary, the cylinder covered with the aluminum or plastic plate (it is possible to develop matrices in these materials), transfers the ink to a rubber roller, which, finally and with the help of the pressure roller, prints the image. on the paper.

The qualities of rubber are ideal in the process, as its flexibility and consistency allow full contact with the substrate, thus guaranteeing an unsurpassed finish, even on porous and irregular materials.

The decomposition of the piece in offset printing presses

Offset work in digital printing requires professionalism and thoroughness. The system works with the division of pigments, for which there are four color plates: cyan, magenta, yellow and black, or what is the same: CMYK.

In the development of digital arts, the separation of colors is fundamental, since each of them must be treated through a technical process that involves the use of inks and chemical agents that repel these oleaginous substances, thus avoiding their reproduction in unwanted areas.

Each plate must be properly aligned, also respecting the angle of the weft that corresponds to each one, as only then is it possible to avoid the appearance of the unpleasant moiré effect.

The superposition of tones from the initial process is what gives rise to the entire color range of the multicolor offset. It is also possible to add metallized pigments or with fluorescent effects. They are not generated from the initial base of inks; they are simply added as a fifth or sixth color. They are obtained through pantones and are often called "spot color" in printing terms.

Technical aspects of the file for digital offset

Customers who have the advice of a graphic arts expert or a professional familiar with the operation of printing systems can be sure that their digital arts will have all the essential features to ensure optimal reproduction. In addition, the means for the preparation of this material have been considerably simplified over the years.
