Gloss or Matte Versions Available
The CW-C4000 uses highly durable
pigment-based inks with gloss or
matte versions available to best suit the
labeling application. The gloss black ink
can print on a wider variety of substrates.
The matte black ink offers a darker, sharper
black text and images on matte media.
Both have been BS5609 certified4
ESC/Label and ZPL II Interface Languages
ZPL II capabilities allow you to experience the advantages of Epson inkjet
technology without reprogramming existing systems. ESC/Label command
extensions can be added to unlock the power of color. Leverage color for
color-coded fields, product pictures, logos and marketing messages to
improve overall business processes and brand image.
High-quality Printing
Epson-engineered PrecisionCore® TFP® printhead technology delivers ultra
sharp text and precise barcodes. It also produces varying droplet sizes that,
coupled with a 1200 x 1200 dpi resolution, can produce a huge gamut of
vibrant, accurate colors, smooth gradations and fine image details.
So, whether the challenge is to produce complex informational
labels or high-quality product labels, the CW-C4000 is up to
the challenge.
Remote Management Tools
The CW-C4000 can be used in large enterprises. To support these
environments, powerful remote management tools make it easy to
manage a fleet of Epson printers on a network. These allow IT support
teams to do mass configuration of printer settings, generate automatic
alerts for items needing attention, deploy automatic firmware updates,
generate reports on usage of devices and consumables, and more.
