Printers in Homes and Printers
Who today does not have a printer at home. Their prices are becoming more affordable and operating costs lower.
Multifunction devices offer increasingly larger scanning resolutions, less margin, larger formats, etc.
But still, such home printers are far behind the professional equipment used in professional printers.
Not to mention the much larger range of techniques used, which have nothing to do with those we know from home printers.
Printed roll, solvent, water, anhydrous - long to exchange.
The quality of such printouts is higher, which entails the obvious higher costs of printing itself.
Most common type of printing
A3 mono laser printer UKOffset 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.
Definition of 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.Źródło: https://en.wikipedia.org/wiki/Laser_printing.
