Trykmetode

Trykmetode is a Danish-Norwegian term meaning "pressure method" or "pressing method." It denotes a class of procedures defined by the use of mechanical pressure to produce a result, and its precise meaning depends on the discipline in which it is used.

In printmaking and graphic arts, trykmetode describes techniques that transfer ink to a substrate through applied pressure. Classic examples include relief printing (such as letterpress), intaglio, lithography, and screen printing. Some contexts also consider digitally driven printing as a pressure-based method, highlighting the role of contact between the printing surface and the substrate.

In engineering and materials testing, trykmetode refers to compression-based testing. Common variants include uniaxial compression tests on metals or polymers, and more complex triaxial compression tests used to study soils and rock mechanics. Measurements from these tests typically yield properties such as strength, stiffness, and deformation behavior.

In food processing and chemistry, trykmetode denotes pressing to extract liquids, oils, or flavors, or to form pellets or tablets. Examples include juice extraction by pressing and oil extraction from seeds using hydraulic or screw presses, as well as sample preparation techniques that rely on compression to create pellets for analytical instruments.

Implementation considerations include selecting appropriate equipment (hydraulic press, screw press, or platen press), controlling load, rate, and temperature when relevant, and ensuring proper specimen preparation and safety. Because the term is broad and field-specific, standards or protocols often refer to a particular named technique rather than the general category of trykmetode.
