Sheet-fed digital printing encompasses various methods, each offering unique advantages: (drukarnia)
Electrophotography (Laser Printing):
Originating from scanner procedures in 1938, electrophotography involves toner (color powder) mixed with a ferromagnetic powder (carrier) that sticks to a chamber's surface exposed to a laser. The toner is then transferred to the substrate and thermally fixed.
Ionography (Electrography):
Similar to electrophotography, ionography changes the chamber's electrostatic charge using a particle stream.
Magnetography:
In magnetography, electrical circuits on a chamber generate magnetic fields, altering toner adhesion based on charge changes, forming a powder image transferred to the substrate.
Elcography:
Introduced in 1984, elcography uses engineered resin colloids to initiate electrochemical reactions between electrodes, forming an image based on electrocoagulation.
Thermography:
This technique creates images on a substrate through direct application of power or color agents on a carrier. Commonly seen in receipt printers and payment terminals.
Inkjet:
Utilizing nozzles to spray liquid toner, inkjet printing is prevalent in desktop printers and industrial devices, offering high color reproduction and speed. However, costs and resolution limitations persist.
Digital printing on large-format machines is distinguished by the ink used:
Plastic:
Utilizing water-based inks without solvents.
Solvent: (druk etykiet )
Using inks dissolved in cyclohexanol, resistant to weather conditions but potentially toxic.
Mild Solvent:
Characterized by reduced solvent content compared to regular solvent printing.
Eco-Solvent:
Utilizing inks based on lactic acid, less harmful but less resistant to weather.
Dye:
Employing water and ethyl glycol-based inks, frequently offering high printing resolution.
UV:
Printing with UV-cured inks, allowing for white or clear ink printing.
Large-format printing typically relies on inkjet technology, where paint is ejected through thousands of nozzles on a print head. This method offers flexibility and versatility, particularly for customized or low-volume prints.
Is digital printing better compared to offset printing?
Digital printing is increasingly popular due to its flexibility and quality, particularly for short runs and personalized prints.
What are the advantages of digital printing?
Digital printing offers rapid production and eliminates the need for printing plates, enabling cost-effective production of even single pieces.
Can I print just one brochure?
Yes, digital printing allows for the production of even a single piece of printed material.
How do I order a personalized print?
Personalized prints require specially prepared files sent to a digital printing house with software for sequential printing. A spreadsheet containing recipient names accompanies the main graphic file, facilitating individualized printing. Assistance from printing house staff is usually available for this process.
