INVIMAGE (II)
Purpose Statement for inversing the printing of text and images from “black-onwhite"
to “white-on-black."
Syntax INVIMAGE | II
Default: NORIMAGE
Reset to default by: PRINTFEED execution
Remarks This statement can only be used in connection with the printing of text
and images (PRTXT and PRIMAGE). In the matrix of the font or image,
all “white” dots will be black and all black dots will be “white.” (Obviously,
“white” means that the dots will not be subjected to heat and the media
therefore will retain its original color, whereas “black” means the color of
the printing.)
This implies that most fonts will be printed on a black background which
ascends and descends slightly more than most of the characters. Not all
fonts are suited for inverse printing. Thin lines, serifs, and ornaments may
be difficult to distinguish. There may also be an imbalance between the
ascending and descending black background.
The same principles apply to images. The normally invisible background
may be larger than expected or be less favourably balanced. Small “white”
details tend to be blurred out by the black background. Therefore, before
using an inverse image, make a printout sample.
INVIMAGE will be revoked by a NORIMAGE statement.
