    Digital Print and Devices Terminology

    ——————————————————————————–
    byte
    8 bits, reflecting values between 0 to 255; used as a basic
    method of measurement of memory or disk size; “K”
    represents 1024 bytes

    color correctness
    the depth and accuracy of an image’s color representation,
    typically influenced by the color depth and palette of an
    image

    color depth
    the amount of color information in an image, reflected in the # of color bits compression, lossless scheme of organizing information in a more compact form where all of the original information is retained, while gaining a moderate level of compaction

    compression, lossy
    scheme of organizing information in a more compact form
    where some information is lost to gain higher levels of
    compaction

    cmyk
    the four process colors — cyan, magenta, yellow and black
    — mixed to provide a color image; typically used in printing
    applications

    dib
    Device Independent Bitmap, a variant of a bitmap (bmp) file consisting of header field, an optional pallette, and bitmap data; bitmap has an additional header field

    display quality
    the characteristics of a display sub-system, such as
    resolution, # of colors, dot pitch, and refresh rate, which
    influence perceived image quality

    dithering
    the technique of making adjacent pixels different colors to
    make them appear like a different color; utilized to add the
    appearance of greater color depth with a limited # of colors

    dot pitch
    distance in millimeters between two holes in the shadow
    mask of a monitor. A smaller dp is better, e.g. 0.28 mm is
    better than 0.36.

    dpi, dots per inch
    sometimes termed pixels per inch, this depicts resolution and is a significant influence on the size of an image file; a higher dpi indicates higher resolution

    eps

    Encapsulated PostScript file format, an Adobe Systems
    graphics file which incorporates PostScript code and can
    contain data as vectors or bitmaps; maximum color depth =
    16.7 million

    gif
    Graphics Interchange Format, a lossy compression
    technique, popular for exchanging files electronically,
    especially on Compuserve; all files have a corresponding
    palette; maximum colors = 256

    jpeg
    Joint Photographers Expert Group; a compressed, lossy
    format which is symmetrical, i.e. takes the same amount of
    time to compress as decompress; maximum colors = 16.7
    million

    lpi, lines per inch
    measurement of the frequency of “dots” represented in a
    halftone image

    mpeg

    high-quality video compression/decompression scheme
    (CODEC) for encoding video and audio for computer
    playback

    palette
    data structure defining the colors utilized in a bitmap image;
    bitmap data is indexed to the palette table

    Photo CD
    Kodak CD-based digital imaging format, where images are
    typically created from 35mm film negatives or slides; includes multiple resolutions of an image in an Image Pac, with all images 24 bpp encoded in YCC format; portability includes Philips CD-Interactive and 3DO Players, as well as PC, Mac & Unix viewers; maximum colors = 16.7 million

    pcd
    see Photo CD

    pcx
    ZSoft format, used widely for paint and desktop publishing
    programs; popular for exchanging images; maximum 16.7
    million colors

    PICT
    standard format for Macintosh, can contain both vector and
    bitmap information; maximum colors = 16.7 million

    pixel
    picture element, or the smallest unit of the computer screen.
    A pixel can be monochrome or up to the pixel depth
    available on your color system. Pixels are also used for
    identifying screen resolution, e.g. 72 pixels per inch.

    pixels per inch, or ppi
    sometimes termed dots per inch, this represents resolution

    print quality
    the characteristics of a printing sub-system, such as the
    number of lines per inch and paper quality, which influence
    the perceived quality of a printed image

    quicktime
    a video compression/decompression scheme (CODEC) for
    encoding video and audio for computer playback; originally
    an Apple Macintosh file format, it is now commonly utilized
    on Windows and Unix systems

    resolution
    measure of the detail in an image; the higher the resolution,
    the higher the amount of detail

    RGB
    red, green, blue mixed to provide a color image, typically
    used in video display applications

    TGA
    Targa format developed by Truevision; usually 15 or 24 bit
    full color images, compressed or uncompressed; maximum
    colors = 16.7 million

    tiff
    Tag Image File Format; industry standard image file format;
    “tags” represent image attributes, compression, and color
    tables; both uncompressed and compressed versions,
    although compressed is not as portable; maximum colors =
    16.7 million

    vector graphics
    image made up of individual objects, which are defined as
    mathematical elements with specific characteristics

    excellent posts/tips guys. but could you do me a favour. put under the post at the bottom the name of the site that you have taken the information from. if this is copyright material im afraid ill have to delete it.

    anyway, put the deltails of the site below this/any, information is taken form & ill go and have a look myself. if i think its ok ill leave it if not ill delete it and send you a personnal message explaining why…

    the same thing goes for clipart & vehicle outlines.

    sorry guys… just trying to keep things right 🙄 🙄
