Printing Registration
In color printing, print registration is the layering of printed patterns to form a multicolor pattern. Registration error is the "position misalignment in the overlapped patterns." Machine components such as the print cylinder, doctor blade assembly, printing plates, stress/friction and more, affect the registration of the machine. Inconsistencies among these components can cause the printing press to fall out of registration; that is when press operators will begin to see defects in their print. There are many different ways to achieve proper registration, many of which employ the alignment of registration marks (pictured right). Many press manufacturers have installed automatic register systems to assist the operator in getting the print back into proper alignment. Purpose When printing an image or a package of some sort that has more than one color, it is necessary to print each color separately and ensure each color overlaps the others precisely. If this is not done, the fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Color Printing
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, ...

Knockout Trapping Overprinting
A knockout (abbreviated to KO or K.O.) is a fight-ending, winning criterion in several full-contact combat sports, such as boxing, kickboxing, muay thai, mixed martial arts, karate, some forms of taekwondo and other sports involving striking, as well as fighting-based video games. A full knockout is considered any legal strike or combination thereof that renders an opponent unable to continue fighting. The term is often associated with a sudden traumatic loss of consciousness caused by a physical blow. Single powerful blows to the head (particularly the jawline and temple) can produce a cerebral concussion or a carotid sinus reflex with syncope and cause a sudden, dramatic KO. Body blows, particularly the liver punch, can cause progressive, debilitating pain that can also result in a KO. In boxing and kickboxing, a knockout is usually awarded when one participant falls to the canvas and is unable to rise to their feet within a specified period of time, typically because of exh ...

Trap (printing)
In printing, trap expresses the degree to which ink already printed on a substrate accepts another layer printed on top of it compared to how well the substrate (e.g., paper) accepts that ink. However, in the era of prepress software, the term came to refer to compensation for misregistration (when two layers of ink are not perfectly aligned) that was traditionally known as "chokes and spreads". Misregistration causes gaps or white-space on the final printed work. Correcting this involves creating overlaps (spreads) or underlaps (chokes) of objects during the print process. Registration Misregistration in the graphical workflow may be caused by human error, inaccuracies in the image setter, the film-to-plate or film-to-film copying steps or instability of the image carrier (e.g., stretch in film or plate), the press or the final media. These issues can be minimized, but not eliminated, given that any mechanical process produces some degree of error. However, the resulting gaps ...

Lithography
Lithography () is a planographic method of printing originally based on the immiscibility of oil and water. The printing is from a stone (lithographic limestone) or a metal plate with a smooth surface. It was invented in 1796 by the German author and actor Alois Senefelder and was initially used mostly for musical scores and maps.Meggs, Philip B. A History of Graphic Design. (1998) John Wiley & Sons, Inc. p 146 Carter, Rob, Ben Day, Philip Meggs. Typographic Design: Form and Communication, Third Edition. (2002) John Wiley & Sons, Inc. p 11 Lithography can be used to print text or images onto paper or other suitable material. A lithograph is something printed by lithography, but this term is only used for fine art prints and some other, mostly older, types of printed matter, not for those made by modern commercial lithography. Originally, the image to be printed was drawn with a greasy substance, such as oil, fat, or wax onto the surface of a smooth and flat limestone plat ...

Fine Arts
In European academic traditions, fine art is developed primarily for aesthetics or creative expression, distinguishing it from decorative art or applied art, which also has to serve some practical function, such as pottery or most metalwork. In the aesthetic theories developed in the Italian Renaissance, the highest art was that which allowed the full expression and display of the artist's imagination, unrestricted by any of the practical considerations involved in, say, making and decorating a teapot. It was also considered important that making the artwork did not involve dividing the work between different individuals with specialized skills, as might be necessary with a piece of furniture, for example. Even within the fine arts, there was a hierarchy of genres based on the amount of creative imagination required, with history painting placed higher than still life. Historically, the five main fine arts were painting, sculpture, architecture, music, and poetry, with p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Printmaking
Printmaking is the process of creating artworks by printing, normally on paper, but also on fabric, wood, metal, and other surfaces. "Traditional printmaking" normally covers only the process of creating prints using a hand processed technique, rather than a photographic reproduction of a visual artwork which would be printed using an electronic machine ( a printer); however, there is some cross-over between traditional and digital printmaking, including risograph. Except in the case of monotyping, all printmaking processes have the capacity to produce identical multiples of the same artwork, which is called a print. Each print produced is considered an "original" work of art, and is correctly referred to as an "impression", not a "copy" (that means a different print copying the first, common in early printmaking). However, impressions can vary considerably, whether intentionally or not. Master printmakers are technicians who are capable of printing identical "impressions" by ...

Free Press (publisher)
Free Press was an American independent book publisher that later became an imprint of Simon & Schuster. It was one of the best-known publishers specializing in serious nonfiction, including path-breaking sociology books of the 1950s, 1960s and 1970s. After a period under new ownership in the 1980s of publishing neoconservative books, it was purchased by Simon & Schuster in 1994. By 2012, the imprint ceased to exist as a distinct entity; however, some books were still being published using the Free Press imprint. History Free Press was founded by Jeremiah Kaplan (1926–1993) and Charles Liebman in 1947 and concentrated on religion and social science. They chose the name Free Press because they wanted to print books devoted to civil liberties. It was launched with three classic titles: ''Division of Labor'' by Emile Durkheim, ''The Theory of Economic and Social Organization'' by Max Weber and ''The Scientific Outlook'' by Bertrand Russell. It was headquartered in Glencoe, Illino ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Visual Inspection
Visual inspection is a common method of quality control, data acquisition, and data analysis. Visual Inspection, used in maintenance of facilities, mean inspection of equipment and structures using either or all of raw human senses such as vision, hearing, touch and smell and/or any non-specialized inspection equipment. Inspections requiring Ultrasonic, X-Ray equipment, Infra-red, etc. are not typically regarded as Visual Inspection as these Inspection methodologies require specialized equipment, training and certification. Quality control A study of the visual inspection of small integrated circuits found that the modal duration of eye fixations of trained inspectors was about 200 ms. The most accurate inspectors made the fewest eye fixations and were the fastest. When the same chip was judged more than once by an individual inspector the consistency of judgment was very high whereas the consistency between inspectors was somewhat less. Variation by a factor of six in inspecti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Color Printing Separations0
Color (American English) or colour (British English) is the visual perceptual property deriving from the spectrum of light interacting with the photoreceptor cells of the eyes. Color categories and physical specifications of color are associated with objects or materials based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space, colors can be identified numerically by their coordinates. Because perception of color stems from the varying spectral sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells. These physical or physiological quantifications of color, however, do not fully explain the psychophysical perception of color appearance. Color science includes the perception of color by the eye and brain, the origin of color in materials, color theory in art, and the physics of electr ...
