Question | Answer |
---|---|
Imagesetters | postscript-driven, uses fast-spinning mirrors, and laser beams. Photographic exposure combined with very high resolution. Exposes light onto film , which in turn is used to expose light onto a printing plate. |
Adding lead | thin strips of metal inserted between rows of words |
Leading | the distance between one line of type and the one above or below it |
Bounding box | the space each letter takes up on a printed page |
Side bearing | the space between the character image itself and the of the bounding box |
The essence of typesetting is | regulating the size of the spaces between printed letters to control the balance and rhythm between black and white |
Type color | the blackness or whitness/ density you see when viewing a page |
Majuscules | capital letters, upper case |
Miniscule | small letters , lower case |
Remington | first typewriter |
Escapement | the movement of paper in a typewriter from side to side |
Justification | spreading the line to its maximum allowable length |
Linecasting | print a line of letters at once |
Font | term that comes from an early French word meaning “molding” or “casting” |
Matrices | molds of type |
Letterpress | a printing press which uses matrices |
Type high | the raised area of a matrice which receives ink |
Recessed areas | below type-high, read as blank space |
“offset” | printed |
Offset litho | double printing, photographic process which allows the plate to be right reading, same as the final image |
Image setters | laser printers which render artwork as type |
Vectorbased | objects defined by vectors |
Vectors | outlines or paths |
Bitmaps | images drawn dot for dot |
Raster | “rake” |
Resolution | the number of apparent dots per inch or centimeter |
Bezier curves | the curves of characters |
Pixels | dots |
Grid fitting | character outlines are superimposed on a grid of pixels, then decided which pixels are to be imaged |
Hints | program instructions |
Typeset quality | above 1000 dpi |
Variable dot size | reduces the jaggedness of type produced at modest resolutions |
Modest resolutions | less than 1000dpi |
Anti aliased | smoothed, grey pixels are added to jagged edges to make them appear less jagged |
Typeface | a collection of characters designed to work together |
Font | the physical thing, the description of the typeface used to image type The font is the cookie cutter, the typeface is the cookie |
Em | the basis for a range of relative units of measurement who’s value are contextual (they depend on the size of the type they’re used in) |
Em square | the upon which all the characters in a font are created |
Baseline | invisible lines that letters sit on |
Leading | line spacing |
Mean line | the height of non-ascending lowercase letters |
X height | line parallel to baseline where top of lowercase letters meet |
Stress | variation in thickness |
Serifs | finishing flourishes at the ends of character’s main strokes, where it flares out |
Sans | without |
Sans serifs | without serifs |
Latins | wedged serif faces |
Bitmap | array of dots |
Alphanumeric | contains letters and numbers |
Slug | a line of type. (molten metal is poured into mold |
Galley | unbroken page of type, column of type |
Linefeed | type is printed onto a page in a vertical column |
Body | piece of material |
Body clearance | extra space, to be sure ascenders do not reach off of a page |
Cap height | height of capital letter |
Ampersand | ‘and’ sign (&) |
Special characters | ellipses, diphthongs, ligatures |
Postscript | adobes patented page description language. Converts vector information into high resolution bitmaps for high quality rendering |
Inkjet printers | microscopic dots of ink are sprayed onto paper at the rate of 300 to 1500 dpi. Lacks postscript, so type rendering isn’t completely accurate |
Laser printers | postscript software installed, have limitations when imaging small type, appear bolder than they are |
Imagesetters | postscript-driven, uses fast-spinning mirrors, and laser beams. Photographic exposure combined with very high resolution. Exposes light onto film , which in turn is used to expose light onto a printing plate. |
