- Machine-finished paper
- Paper stock that is given its surface gloss while still inside the paper machine, a process known as calendering. Additional smoothness is sometimes achieved with supercalendering.
- Machine proof (press proof)
- A proof used to check the result of the entire printing process. It is the most complex control tool in the printing process; its greatest advantage is that it provides a realistic impression of the final product, independent of the preprint process. Machine proofs come closest to the printed result when produced on the paper to be used for the print run.
- A series of commands performed by a single keystroke or function call that facilitates the input of complex commands.
- Magazine paper
- See "illustration printing paper".
- The term given by Heidelberger Druckmaschinen AG to a device used for inserting supplements into newspapers and magazines. The unit can process up to 30,000 copies an hour and can insert up to 80 different products. The Magnapak can insert and sort either in sequence or simultaneously, and has been designed without shafts for simple operation and minimal maintenance.
- Magnetic printing inks
- Inks that react to magnetic fields and thus, with the help of suitable sensors, can be used for machine-based identification of labels and other similar applications.
- The historical terms for capital or upper-case letters.
- Manutius, Aldus (1449-1515)
- One of the most prominent letterpress printers of the Italian Renaissance. In 1493, Manutius founded a print shop in Venice and subsequently published a series of compact and inexpensive but nevertheless highly scientific works from classical Greek, Latin and Italian authors. Around 1,000 copies of these “Aldines,” as they were known, were produced.
- Map paper
- Paper with particularly good dimensional stability.
- The free areas on a printed page between the edges of the text and the page edges. According to the position on the page, it is possible to distinguish between head, foot and side margins and the central gutter. When measuring the margin widths, ratios are often used. The gutter has a value of two and the other margin widths in the sequence head-side-foot are assigned values in relation to this.
- Master page
- Template on which the elements (such as headers, footers, page numbers, etc.) to appear on every page of a document are represented.
- McLuhan, Marshall (1911-1980)
- The Canadian literary scholar and communications theorist, whose work focuses on changes elicited in society by mass media. McLuhan achieved fame with his book “Understanding Media: The Extensions of Man” (1964), in which he argues that modern electronic media will eventually turn human awareness and knowledge into an entity shared by all of society, just as electrotechnology has turned the human nervous system into a global network. McLuhan taught at various universities throughout Canada and the USA. He coined the term “the global village”, which refers to the way the entire global community can be brought together by means of electronic communication.
- Media mix
- Term used to describe combinations of different media such as television, radio, Internet, newspapers and magazines for marketing and promotional purposes. The right mix is the one which best reaches the target audience.
- A unit of measurement equal to 1,024 kilobytes, or 1,048,576 bytes.
- Mergenthaler (1854-1899)
- Inventor of the “Linotype” mechanical composition machine, which supplied complete lines of text cast in lead for letterpress printing. Following an apprenticeship as a watchmaker, Mergenthaler emigrated to the U.S. in 1872 where, following many years of experimentation, he patented the Linotype as the first fully functional line composition machine, which would soon replace slow and laborious hand composition.
- Phenomenon by which color samples with different spectra appear to match under a particular type of illuminant, although under other illuminants they show a color mismatch.
- See "HWC".
- Extremely small print that is only legible when highly magnified. It is used as a security element on banknotes and other documents at risk of being forged. The image resolution of color copiers and other similar machines is insufficient to reproduce microprint.
- A term for books with covers no higher and wider than 7.6 centimeters (three inches). One of the earliest known printed mini-books of the post-incunabula era is the book of hours produced by Lucantonio Giunta on May 4, 1506 in Venice. The book was titled “Officium Beatae Mariae Virginis secundum consuetudine romane curie.” It measures just 7.2 x 5.1 cm, was printed on parchment and contains illuminated, full-page woodcuts.
- The historical term for small or lower-case letters.
- Mullen tester
- A device invented by the American engineer John Mullen to test the bursting strength of paper.
- Term used for media products and services which are saved, transmitted and depicted electronically. Important features of multimedia include the combination of static (text and image) and dynamic (audio, animation and video) elements and the interactivity of its content. In order to use multimedia, it must be possible to transmit data between the content location and the user in both directions. Video components involve large quantities of data which require correspondingly high transmission rates.
- Murray-Davies formula
- Equation to calculate the optical area coverage or the total reflection factor from the combined values of printed and non-printed areas. The tone values in a densitometer are defined in accordance with this equation.
