TrueMatch™ Printing Technology
The SD Series card printers lead the industry by providing TrueMatch color printing that
conforms to the same color standard used by Microsoft and Hewlett Packard in their viewing
devices such as monitors and LCD screens. The TrueMatch printing technology emulates the
Internet standard sRGB color space.
TrueMatch printing technology greatly improves the screen to printed card color match
compared to the SP and CP Series card printers. In the past, Datacard printers used the Cyan,
Magenta, and Yellow color space to optimize the color gamut available from the ribbon.
TrueMatch technology sRGB printing emulates the color gamut used by most computer
monitors and LCDs, and it uses the color space where the sRGB and CMY colors overlap to
produce optimal printing results. (See Illustration 1 below.)The actual results achieved depend
on factors such as monitor settings and display colors that are calibrated to accurately show
the sRGB color space.
TrueMatch printing technology helps to solve the issue created when the image a customer
sees on their monitor looks perfect, and then the resulting colors on the card printed with an
YMCK ribbon do not match. Illustration 2 below shows the challenge of taking the monitor’s
sRGB, red, green, and blue colors and sending them to a printer that will print the image with
the yellow, magenta, and cyan panels of the print ribbon. The RGB green is brighter, the red is
a true red, and the blue does not have the purple hue as seen on the CMYK side of the
diagram. With TrueMatch technology color management, the printer is able to receive the
sRGB color profile from the monitor and convert it into the closest match possible using the
YMC panels of the ribbon. The SD Series printers compress the sRGB colors so that they are
represented into colors that can be most accurately printed with the ribbon.
