INVIMAGE (II)
Field of Application
Statement for inversing the printing of text and images from
black-on-white" 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 dif cult 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.
