  2. Lookup table - Wikipedia

    en.wikipedia.org/wiki/Lookup_table

    A common solution is to initially compute the sine of many evenly distributed values, and then to find the sine of x we choose the sine of the value closest to x through array indexing operation. This will be close to the correct value because sine is a continuous function with a bounded rate of change. [10]: 6 For example: [11]: 545–548

  3. Spreadsheet - Wikipedia

    Formulas in the B column multiply values from the A column using relative references, and the formula in B4 uses the SUM() function to find the sum of values in the B1:B3 range. A formula identifies the calculation needed to place the result in the cell it is contained within. A cell containing a formula, therefore, has two display components ...

  4. Gang run printing - Wikipedia

    en.wikipedia.org/wiki/Gang_run_printing

    Gang-run printing allows multiple jobs to share the setup cost. For example, a 28" x 40" sheet can hold 9 4" x 6" at 5,000 or 18 2,500 postcards (each card takes 4.25" x 6.25" on the sheet to accommodate full bleed. Gang-run printing has been one of the driving forces in the large drop in the price for full-color printing. [citation needed]

  5. Dot gain - Wikipedia

    en.wikipedia.org/wiki/Dot_gain

    Dot gain, or tonal value increase, is a phenomenon in offset lithography and some other forms of printing which causes printed material to look darker than intended. It is caused by halftone dots growing in area between the original printing film and the final printed result.

  6. Rich black - Wikipedia

    en.wikipedia.org/wiki/Rich_black

    Wetness is not a problem with laser printers, however, and registration black (or "400% black") produces very striking results in laser prints. [5] Rich black is often regarded as a color that is "blacker than black". While this is impossible from the point of view of color theory, the difference can often be seen in the printed piece. The ...

    en.wikipedia.org/wiki/Color_difference

    The CIE 1976 color difference formula is the first formula that related a measured color difference to a known set of CIELAB coordinates. This formula has been succeeded by the 1994 and 2000 formulas because the CIELAB space turned out to be not as perceptually uniform as intended, especially in the saturated regions.

    The spiro form of an oxazine is a colorless leuco dye; the conjugated system of the oxazine and another aromatic part of the molecule is separated by an sp 3-hybridized "spiro" carbon.

    A word processor (WP) [1] [2] is a device or computer program that provides for input, editing, formatting, and output of text, often with some additional features.. Early word processors were stand-alone devices dedicated to the function, but current word processors are word processor programs running on general purpose computers.
