We are all familiar with the standard way
of personalising plastic cards. You take a
blank white plastic card or smartcard, run
it through a desktop printer and hey
presto! That is the way you do it for instant
issuance and that is the same technique
used by bureau services right?
Well, now there is a better way for bureaux
to personalise cards and it has many
advantages for the customer. The process
is known as sheet-fed or Digital Print
process and it gives you the Digital Print
Advantage.
Traditional desktop printing over-prints
cards using ink ribbons. The lowest-cost
process is simple wax-transfer which is fine
for printing a name or card number or solid
colour but it cannot print good quality
photographs or colour images. The more
common are dye-sublimation printers
which give better control of colour but
cannot print edge-to-edge.

Re-transfer printers overcome this by
printing onto a transfer ribbon which is
then applied to the card giving good quality
edge-to-edge printing on uneven surfaces.
But this quality comes at a big cost: the
ribbons for a 2-sided, 4-colour card can add
up to 50p to the cost of a blank card.
With digital print techniques, we avoid
these high consumable costs. A set of card
images are created from a scheme database
and a sheet of 21 card images are printed
in very high quality. This sheet is then
used to make a set of 21 smartcards by
laminating the chips & antennae to the
printed sheet and between two protective
layers. The whole array is then punched
out to single cards. The process can print
over 10,000 cards per hour, hundreds of
times faster than re-transfer!

Key Digital Print Advantages
|
| Quality |
2,400dpi compared to 300dpi of desktop printers gives much better quality printing. |
| Durability |
Unlike desktop printing, for DP the print layer is
below the surface giving excellent wear. |
| Cost |
Consumable costs for printing are just ink and toner – no more expensive colour ribbons! |
