Internet printing

Online printers are gaining more and more supporters, not surprisingly when more and more commerce is done online. This is a very convenient solution, because you can immediately overcome mistakes made by potential customers when placing an order.

Often, they send a bad file in the wrong format, with the web printing this error is still captured by the script itself accepting the order. Of course, such printers also have their drawbacks, ie the lack of the possibility of an individualized approach to the client and his needs, unless we get a really good printing house.


Most common type of printing

Offset printing is the most popular type of printing in today's printing industry. It is true that it has many varieties and uses different techniques and materials (paint, paper). The main division is cold printing, where the paint is fixed by soaking into paper. While the 'hot' offset where the printed paper web passes through the drying tunnel.

The classic offset (water) is associated with the use of water rollers and hydrophilic and hydrophobic surfaces, however, this method is already abandoned due to the difficulty in obtaining a good balance of water and oil paint.

The successor of this method is anhydrous offset printing where silicone molds are used instead of water.


Wikipedia about laser printing

Laser printing is an electrostatic digital printing process. It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially charged image.1 The drum then selectively collects electrically charged powdered ink (toner), and transfers the image to paper, which is then heated in order to permanently fuse the text, imagery, or both. As with digital photocopiers, laser printers employ a xerographic printing process. However, laser printing differs from analog photocopiers in that the image is produced by the direct scanning of the medium across the printer's photoreceptor. This enables laser printing to copy images more quickly than most photocopiers.
