Gravure printing is one of the oldest printing processes that is still used today.
A distinction is made between sheet-fed gravure printing, for smaller print runs, and rotogravure printing, for larger print runs. The latter is also the most common process.
In gravure printing, the print image is engraved into the printing cylinder (or printing plate). It is then dipped into the ink and the excess ink is scraped off, leaving only the ink in the depressions (cells). Finally, this ink is transferred to the printing substrate using high pressure and the absorbency of the paper.
With less absorbent materials such as metal or plastic, this is achieved through electrostatic charge.
In addition to the high print quality, rich colours and an even ink application, gravure printing offers the advantage of regulating the amount of ink applied due to cells of varying depth. This way, halftones can actually be represented – something that offset printing can only simulate.
Gravure printing is mostly used for magazines and catalogues, plastic and metal foils, stamps, securities or even banknotes.
Gravure printing can also be used for artistic purposes, with the preference for hand-engraving.
PSR stands for “Process Standard Rotogravure”, a standard provided by Fogra, ECI and the German Printing and Media Industries Federation (bvdm).
The Process Standard Rotogravure is a standard developed for gravure printing.
As the printing industry is in a constant state of change, the PSR_V2 standards were revised in 2019 to reflect the new paper colouring and measuring conditions:
PSR LWC Standard V2 M1 (2019)
The successor of LWC Standard (PSR_LWC_STD_V2_PT)
PSR LWC Plus V2 M1 v2 (2020)
The Sucessor of LWC Plus (PSR_LWC_PLUS_V2_M1, PSR_LWC_PLUS_V2_PT )
PSR SC Standard V2 M1 (2019)
The successor of SC Standard (PSR_SC_STD_V2_PT)
PSR SC Plus V2 M1 (2019)
The successor of SC Plus (PSR_SC_PLUS_V2_PTc)
PSR MF V2 M1 (2019)
The successor of News Plus (PSRgravureMF)
LWC Standard (2009)
LWC Plus (2009)
SC Standard (2009)
SC Plus (2009)
News Plus (2004)
