What is web print?

Web Press is a type of print press that receives paper in roles rather than in individual sheets. Most pressed on the web are rotary presses, which means that the plates used for printing are mounted on the cylinders. Rolls paper or "sites" complicate around this cylinder, which can come in different widths and then run at the other end of the press. Web presses are used for extensive printing runs, which are needed tens or hundreds of thousands of copies. Most books and newspapers are printed on web presses.

Web printing can be used by three different printing techniques. In the offset lithography, one of the most common, the image is transferred to the cylinder from the plate. This method is fast and highly efficient, even if it can be prone to blur. RotoGravura includes the use of a engraved cylinder or cylinder with an engraved plate mounted to it, while flexography uses a flexible elevated plate to transmit ink to paper.

Huge web presses capable of handling the truth of the big tasks are usually our NASThe melted to thermal, which means that once the paper turns around the cylinder with the board, the ink is exposed to not be blurred. Smaller cold pressing requires more careful paper processing because the ink is not exposed to ink, so it will be prone to blur until it goes. Both are capable of continuous feeding using joints when the role of paper reaches the end.

In some cases, the web print may print on both sides of the paper at the same time, as necessary for a book or newspaper. In other cases, the paper is curled when it comes out of the press and brings back to the other side. In both cases, once the paper is printed, it can be cut, folded, stitched, glued and sewed to the desired shape or size. Automated machines are available for all these tasks.

Starting the web press requires a high degree of skill. Presperson is able to be able to maintain a voltageConsistent paper that the printing does not stop running, and he or she must maintain ink's stocks and constantly check the print output to confirm that it prints them correctly without any incorrect registrations. A small mistake can be costly when the web printing is involved, because it costs a lot of money to stop or reworking the print run, which criticizes attention at every stage.
