Undesirable "stairstep" color breaks in a smooth gradation or color vignette, caused by gradations that are excessively long, or by limitations in the number of colors available in an electronic file or the number of colors that can be reproduced on press. Can usually be minimized by adding small amounts of noise to the gradation.
In a color gradation, visibly distinct differences, or sequential patterns between color levels, instead of smooth transition of colors or other effects. Banding can take place in continuous-tone images on a display using less than 24-bit information, or when printing gradients without sufficient color information. Can also apply to an imperfect airbrushed or painted gradation.
Unaesthetic jagged lines that occur when printing color breaks in gradations; caused by tonal jumps when adjacent dots become interconnected, leading to a perceptible increase in tone value. (See also “tonal jumpâ€.)
An undesirable graphic effect in which a gradation contains visible stepping of shades.
An abnormality occuring in gradations causing a stair-stepped appearance. Introducing noise to a gradient will help to reduce banding.
This occurs in gradations when a screen percent change that is too small is made over an area that is too large.
(1) A hair shaft having various colors. Normally associated with an agouti coat. (2) An unbroken vertical circle of marking color, extending around the body of the Harlequin.
An artifact of color gradation in computer imaging, when graduated colors break into larger blocks of a single color, reducing the "smooth" look of a proper gradation.
A visible stair stepping of shades in a gradient. For best results, gradients should be created in PhotoShop. With the advent of the Postscript level 3 ripping system at BOPI, this issue is virtually eliminated.
Patterns (stripes) on a print caused by insufficient color or gray-scale ranges within the output device's image processor, or insufficient information contained within the original scan. Creates harsh, well-defined transitions between different color ranges.
A loss of image quality in which continuous tones or gradients are broken into discrete colours or shades of grey because an image or output device does not contain or support enough tonal levels. Also known as posterization.
It is the presence color zoning lines, or "bands" as it is also known, in some minerals.
An image defect where solid bands of color appear in an area that should contain a smooth, gradual transition between colors.
The horizontal lines that sometimes appear when printing graphics. This occurs when the print head is misaligned. See also MicroWeave.
In digital printing, this term refers to patterns on a print caused by insufficient color or gray-scale ranges within the output device's image processor, or insufficient information contained within the original scan. Banding is most noticeable in printed areas that fade from light to dark.
The horizontal lines that sometimes appear when printing graphics. This occurs when the print heads are misaligned. See also MicroWeave.
A printing defect characterized by light or dark lines in an image in the direction of the printing. In the case of inkjet imaging it is caused by a jet or printhead that is not properly aligned, inoperative, or incorrectly indexed. The chemistry of the substrate surface can also contribute to banding.
Contours or steps in a gradient produced by an inadequate range of brightness levels available to display the image. Banding can occur when displaying continuous tone images on a display using less than 24 bits of color information, or when printing a gradient that spans an extended distance without an adequate range of colors to create smooth transitions from shade to shade.
Patterns (stripes) on a print caused by insufficient colour or greyscale ranges within the output devices image processor, or insufficient information contained within the original scan. Creates harsh, well defined transitions between different tonal ranges, where a smooth transition was required.
A picture artifact or fault whereby smooth brightness or color gradients appear to be comprised of bands of brightness or color, often the result of too few bits used to represent each sample of a picture. Banding could make a billiard ball look like a sliced onion.
A visible streak through a photograph created by dirt or a malfunction of the printing device.
The presence of extraneous lines in a printed page. Banding generally occurs when a colour printer needs to pass the print head over a page multiple times to print each color. If the page isn't exactly lined up for each pass, lines may appear. Such printers are called multi-pass printers. Because of the banding problem, single-pass printers - those that print all the colors in one pass - are generally better.
An artifact of colour gradation in computer imaging, when graduated colours break into larger blocks of a single colour, reducing the "smooth" look of a proper gradation. Barrel Distortion - A common geometric lens distortion causing an acquired image to pucker toward the center and be "rounded" along the outer edges.
The visible break between colors in a gradient.
Banding is the result of substandard printing that affects the graduation of colors, resulting in distinct bands of colors on the page. This is usually caused by improper alignment, or clogged nozzles in the print head.
A visible stepping of shades in a gradient. A artifact of colour gradation in computer imaging, when graduated colours break into larger blocks of a single colour, reducing the smooth look of a proper gradation.
A pattern of horizontal or vertical lines that occurs in solid colors, continuous-tone tints, gradations or images, instead of a smooth color or transition or colors. Banding can appear on computer monitors when viewing images with less than 24-bit information, or on printers due to a problem with the shape of the curve.
Individual bands of color growing in a cross-wise direction.
A visible stair stepping of shades in a gradient or blend.
Bands of discrete color or tone that appear when an inkjet cannot reproduce a smooth graduation from one color to another. Instead there are noticeable jumps between one value and the next.
Distinct pattern alterations, rather than a smooth transition of colors or other effects in a gradient. Occurs in continuous tone images when displayed using less than 24 bits of digital information or if printing gradients without sufficient color information.
A disruption in the gradation of colors in a digital image. Banding can also occur when printing images on a multi-pass color printer.
