Four-color Process
Color printing or colour printing is the reproduction of an image or text in color (as opposed to simpler black and white or monochrome printing). Any natural scene or color photograph can be optically and physiologically dissected into three primary colors, red, green and blue, roughly equal amounts of which give rise to the perception of white, and different proportions of which give rise to the visual sensations of all other colors. The additive combination of any two primary colors in roughly equal proportion gives rise to the perception of a secondary color. For example, red and green yields yellow, red and blue yields magenta (a purple hue), and green and blue yield cyan (a turquoise hue). Only yellow is counter-intuitive. Yellow, cyan and magenta are merely the "basic" secondary colors: unequal mixtures of the primaries give rise to perception of many other colors all of which may be co Modern techniques While there are many techniques for reproducing images in color, ...

Monochrome
A monochrome or monochromatic image, object or palette is composed of one color (or values of one color). Images using only shades of grey are called grayscale (typically digital) or black-and-white (typically analog). In physics, monochromatic light refers to electromagnetic radiation that contains a narrow band of wavelengths, which is a distinct concept. Application Of an image, the term monochrome is usually taken to mean the same as black and white or, more likely, grayscale, but may also be used to refer to other combinations containing only tones of a single color, such as green-and-white or green-and-red. It may also refer to sepia displaying tones from light tan to dark brown or cyanotype ("blueprint") images, and early photographic methods such as daguerreotypes, ambrotypes, and tintypes, each of which may be used to produce a monochromatic image. In computing, monochrome has two meanings: *it may mean having only one color which is either on or off (also kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gamut
In color reproduction, including computer graphics and photography, the gamut, or color gamut , is a certain ''complete subset'' of colors. The most common usage refers to the subset of colors which can be accurately represented in a given circumstance, such as within a given color space or by a certain output device. Another sense, less frequently used but still correct, refers to the complete set of colors found within an image at a given time. In this context, digitizing a photograph, converting a digitized image to a different color space, or outputting it to a given medium using a certain output device generally alters its gamut, in the sense that some of the colors in the original are lost in the process. Introduction The term ''gamut'' was adopted from the field of music, where in middle age Latin "gamut" meant the entire range of musical notes of which musical melodies are composed; Shakespeare's use of the term in ''The Taming of the Shrew'' is sometimes attributed to ...

Sutra
''Sutra'' ( sa, सूत्र, translit=sūtra, translit-std=IAST, translation=string, thread)Monier Williams, ''Sanskrit English Dictionary'', Oxford University Press, Entry fo''sutra'' page 1241 in Indian literary traditions refers to an aphorism or a collection of aphorisms in the form of a manual or, more broadly, a condensed manual or text. Sutras are a genre of ancient and medieval Indian texts found in Hinduism, Buddhism and Jainism. In Hinduism, sutras are a distinct type of literary composition, a compilation of short aphoristic statements.Gavin Flood (1996), ''An Introduction to Hinduism'', Cambridge University Press, , pages 54–55 Each sutra is any short rule, like a theorem distilled into few words or syllables, around which teachings of ritual, philosophy, grammar, or any field of knowledge can be woven. The oldest sutras of Hinduism are found in the Brahmana and Aranyaka layers of the Vedas. Every school of Hindu philosophy, Vedic guides for rites of passag ...

Buddhist
Buddhism ( , ), also known as Buddha Dharma and Dharmavinaya (), is an Indian religion or philosophical tradition based on teachings attributed to the Buddha. It originated in northern India as a -movement in the 5th century BCE, and gradually spread throughout much of Asia via the Silk Road. It is the world's fourth-largest religion, with over 520 million followers (Buddhists) who comprise seven percent of the global population. The Buddha taught the Middle Way, a path of spiritual development that avoids both extreme asceticism and hedonism. It aims at liberation from clinging and craving to things which are impermanent (), incapable of satisfying ('), and without a lasting essence (), ending the cycle of death and rebirth (). A summary of this path is expressed in the Noble Eightfold Path, a training of the mind with observance of Buddhist ethics and meditation. Other widely observed practices include: monasticism; "taking refuge" in the Buddha, the , and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Book Frontispiece
A frontispiece in books is a decorative or informative illustration facing a book's title page—on the left-hand, or verso, page opposite the right-hand, or recto, page. In some ancient editions or in modern luxury editions the frontispiece features thematic or allegorical elements, in others is the author's portrait that appears as the frontispiece. In medieval illuminated manuscripts, a presentation miniature showing the book or text being presented (by whom and to whom varies) was often used as a frontispiece. Origin The word comes from the French ''frontispice'', which derives from the late Latin ''frontispicium'', composed of the Latin ''frons'' ('forehead') and ''specere'' ('to look at'). It was synonymous with ' metoposcopy'. In English, it was originally used as an architectural term, referring to the decorative facade of a building. In the 17th century, in other languages as in Italian, the term came to refer to the title page of a book, which at the time was often ...

Woodblock Printing
Woodblock printing or block printing is a technique for printing text, images or patterns used widely throughout East Asia and originating in China in antiquity as a method of printing on textiles and later paper. Each page or image is created by carving a wooden block to leave only some areas and lines at the original level; it is these that are inked and show in the print, in a relief printing process. Carving the blocks is skilled and laborious work, but a large number of impressions can then be printed. As a method of printing on cloth, the earliest surviving examples from China date to before 220 AD. Woodblock printing existed in Tang China by the 7th century AD and remained the most common East Asian method of printing books and other texts, as well as images, until the 19th century. '' Ukiyo-e'' is the best-known type of Japanese woodblock art print. Most European uses of the technique for printing images on paper are covered by the art term woodcut, except for th ...

Miniature (illuminated Manuscript)
A miniature (from the Latin verb ''miniare'', "to colour with '' minium''", a red lead) is a small illustration used to decorate an ancient or medieval illuminated manuscript; the simple illustrations of the early codices having been miniated or delineated with that pigment. The generally small scale of such medieval pictures has led to etymological confusion with minuteness and to its application to small paintings, especially portrait miniatures, which did however grow from the same tradition and at least initially used similar techniques. Apart from the Western, Byzantine and Armenian traditions, there is another group of Asian traditions, which is generally more illustrative in nature, and from origins in manuscript book decoration also developed into single-sheet small paintings to be kept in albums, which are also called miniatures, as the Western equivalents in watercolor and other mediums are not. These include Arabic miniatures, and their Persian, Mughal, Ottoman ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manuscript
A manuscript (abbreviated MS for singular and MSS for plural) was, traditionally, any document written by hand – or, once practical typewriters became available, typewritten – as opposed to mechanically printed or reproduced in some indirect or automated way. More recently, the term has come to be understood to further include ''any'' written, typed, or word-processed copy of an author's work, as distinguished from the rendition as a printed version of the same. Before the arrival of printing, all documents and books were manuscripts. Manuscripts are not defined by their contents, which may combine writing with mathematical calculations, maps, music notation, explanatory figures, or illustrations. Terminology The study of the writing in surviving manuscripts, the "hand", is termed palaeography (or paleography). The traditional abbreviations are MS for manuscript and MSS for manuscripts, while the forms MS., ms or ms. for singular, and MSS., mss or mss. f ...

Rubric
A rubric is a word or section of text that is traditionally written or printed in red ink for emphasis. The word derives from the la, rubrica, meaning red ochre or red chalk, and originates in Medieval illuminated manuscripts from the 13th century or earlier. In these, red letters were used to highlight initial capitals (particularly of psalms), section headings and names of religious significance, a practice known as rubrication, which was a separate stage in the production of a manuscript. Rubric can also mean the red ink or paint used to make rubrics, or the pigment used to make it. Although red was most often used, other colours came into use from the late Middle Ages onwards, and the word rubric was used for these also. Medievalists can use patterns of rubrication to help identify textual traditions. Various figurative senses of the word have been extended from its original meaning. Usually these senses are used within the set phrase "under hateverrubric", for example ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Initial
In a written or published work, an initial capital, also referred to as a drop capital or simply an initial cap, initial, initcapital, initcap or init or a drop cap or drop, is a letter at the beginning of a word, a chapter, or a paragraph that is larger than the rest of the text. The word is derived from the Latin ''initialis'', which means ''standing at the beginning''. An initial is often several lines in height and in older books or manuscripts are known as "inhabited" initials. Certain important initials, such as the Beatus initial or "B" of '' Beatus vir...'' at the opening of Psalm 1 at the start of a vulgate Latin. These specific initials in an illuminated manuscript were also called initiums. In the present, the word "initial" commonly refers to the first letter of any word or name, the latter normally capitalized in English usage and is generally that of a first given name or a middle one or ones.

Ordnance Survey
Ordnance Survey (OS) is the national mapping agency for Great Britain. The agency's name indicates its original military purpose (see ordnance and surveying), which was to map Scotland in the wake of the Jacobite rising of 1745. There was also a more general and nationwide need in light of the potential threat of invasion during the Napoleonic Wars. Since 1 April 2015 Ordnance Survey has operated as Ordnance Survey Ltd, a government-owned company, 100% in public ownership. The Ordnance Survey Board remains accountable to the Secretary of State for Business, Energy and Industrial Strategy. It was also a member of the Public Data Group.
