Intaglio

Intaglio is the family of printing and printmaking techniques in which the image is incised into a surface and the incised line or sunken area holds the ink. It is the direct opposite of a relief print. Normally, copper or zinc plates are used as a surface or matrix, and the incisions are created by etching, engraving, drypoint, aquatint or mezzotint. Collagraphs may also be printed as intaglio plates.

 
OFFSET INK

Important innovations have been made in the formulation of Offset or “paste” inks over the last few years, keeping pace with the evolutions that have marked the Graphic Industry :

• The appearance of high technology printing equipment with faster and faster printing speeds, requiring inks with excellent printing stability.
• A diversification in the range of printed substrates (recycled paper, more varied synthetic substrates, etc.) requiring more and more versatile inks.
• An evolution in environmental legislation (VOC emissions, recycling of packaging, etc.).


 
UV INK

UV inks and varnishes were first introduced to the Graphic Industry in the early 1970s. However, it is only over the last twenty or so years that their use has become widespread.
UV technology provides some considerable technical advantages for the printer, whatever the type of printing process employed (offset, letterpress, flexo, waterless, varnishing, serigraphy, etc.

• Productivity gains due diate drying under the Ultra Violet radiation, enabling all types of overprinting or cutting and folding operations to be carried out immediately after printing.
• High print quality (excellent gloss, good physical and chemical resistance).
• Clean technology without any VOCs (Volatile Organic Compounds), thereby preserving the environment.
