Standard P3xx Color Card Printers have two
image buffers—one used for color and another
used for monochrome. The single color buffer re

quires print passes that follow each of the three
downloads associated with full-color dye
sublimation imaging. The single monochrome
buffer requires print passes following separate
downloads for resin black and for overlay varnish in
situations that require different bit-maps. However,
because of its durability, card areas with resin im
-
ages may not require varnish for the associated ul
-
traviolet protection. Therefore, by using a reverse
imaging for varnish, the same bit-map used for resin
produces a varnish overlay that omits the areas with
resin. Reverse imaging also means that a full-
coverage varnish can result after a clear command
sent for the monochrome buffer.
P310 (all models) and P300 Color Printers
with Extended Memory have the potential for
three color buffers and two monochrome buffers.
These buffers have the same uses as described for
the P3xx Color above. However, more buffers
means that a high probability exists that data for a
complete card image can download in a single host
access. With a complete image resident in the
printer, multiple card prints can occur at a much
faster rate.
P4xx's have all the same implementations as the
P3xx Color, including Extended Memory as a P400
option. Because P4xx's have a Card-Flip assembly,
these models respond to commands related to du
-
plex printing. P420 Card-Flip Stations can reject
cards into an associated hopper and includes re
-
lated commands. P420s also have an interface that
supports the programming of Proximity Cards (also
called Contactless Cards).
P500s have all the same implementations as a
P400, including Extended Memory, Smart Card
stations, and Magnetic Encoders as options. How
