There are many applications for DTG HM1 Kiosk™ printing. Besides T-Shirts, it can print on

ladies tops, men’s polo shirts, tote bags, aprons, towels, caps, mouse pads and bibs. Some

products will require pre-treatment with undercoats as well as the application of top coats to

protect the print. By choosing the DTG Uni range of inks, you can print on a range of non-

textile items such as wood, glass, tiles, golf balls etc.

The DTG HM1 Kiosk™ with White Ink will require not only the standard Windows printer driver

for you computer, but also our specially developed RIP program which “interprets” the image

data and converts it to instructions relating to the printing of white ink for the printer.

Printer Drivers for Windows and the RIP software have been included in your DTG HM1 Kiosk™

package. You can create your artwork from many graphic applications such as Adobe

Photoshop, Adobe Illustrator, Adobe InDesign, CorelDRAW, QuarkXPress, Macromedia

Freehand, convert it (where necessary) to a format which can be read by our RIP, and then

open that image from within the RIP for printing to your garment or fabric.

1.2 DTG TEX Textile Inks

The Epson R2400 printer, and therefore the DTG HM1 Kiosk™, is based on a CMYK colour

process. This process uses blends of 4 colours to make every colour in the spectrum. The

colours are C

yan, Magenta, Yellow and Black. Specifically, the Epson R2400 uses a eight

colour process using two shades of Cyan and Magenta, and three shades of Black. There is a

primary and a light shade of each of these colours, and the light shades provide an accent to

the primary colours giving them a richer blend. The additional light shade of black provides

greater definition.

In the DTG HM1 Kiosk™ with White Ink, the light colours are replaced with White Ink. White

Ink is a water based titanium dioxide solution. The titanium dioxide is ground into a fine

powder and mixed with other binders to allow it to dry and adhere to the pre-treated fabric.

Titanium dioxide is what gives the ink its bright white properties, and this brightness gives the

coloured ink layer a vibrant and rich colour.

White Ink Properties and Maintenance

Because of the chemical properties of white ink it requires much more maintenance than the

colour inks. Titanium dioxide is a mineral and does not dissolve in liquids. This means that

the titanium dioxide will, over a period of time, settle to the bottom of the container (being

the ink bottles, ink tubes and / or dampers). Once complete, separation of the titanium

dioxide from the binders and other components in the ink cannot be reversed! It is therefore

critical that the ink be shaken daily, or at minimum every 2-3 days. This includes any unused

white ink that you may have in stock. For the ink in the ink bottles loaded on the printer, the

DTG HM1 Kiosk is provisioned with an automatic ink agitation system. As long as the printer is

turned on, the ink agitation system will activate at a pre-defined time interval and mix the

white ink. It will also perform a head clean to keep the ink moving through the ink tubes

while the printer is not in use.

As well as the automatic head cleaning, it is recommended that you print a white ink sample

each day to turn the ink over in the print head, ink tubes and dampers.
