64 P640i Card Printer User Guide 980541-001 Rev. A
Depending on the application used to create the card
layout, elements of the design may be identified in
different ways to the printer driver. This printer driver
recognizes, and rasterizes, five types of elements: text,
lines and pixels, area fills, monochrome bitmaps, and
color bit maps:
• Text is text which is sent explicitly as such to the
printer driver.
• Lines and pixels are lines and dots (pixels) sent as
such to the printer driver.
• Area fills are color-filled geometric shapes.
• Monochrome bitmaps are 1-bit bitmaps (every
pixel either black or white).
• Color bitmaps are full color uncompressed pixel
maps.
The above elements may not always be sent to the
driver as expected. For example, a bar code may be
sent as text, a series of area fills, or a monochrome
bitmap. Results will vary by application used to create
the card design. Another variable, again controlled by
the card layout application, is the precedence
(stacking order) of the various element types in the
event that one or more of them overlap.
Any of the above five elements may be selected for
black extraction when the ribbon is set up to apply
YMC (color) and K (black) to the same surface of the
card. In this condition, the driver generates an
extracted K image by looking for “true-black”
features in the selected element types, that is,
instances where all three YMC values are at the
maximum (full intensity). Each such true-black
instance generates a corresponding cluster of black
pixels in the extracted image, which will be printed
with the K (black) panel either on top of the YMC
image, or replacing it entirely – your choice.
