Preparing a white job in your design software Prepare the job using layers. Before sending it to the RIP, you should ensure that the part of the image to be printed in white is on a separate layer named spot: a name that the printer will recognize. When the image is ready, send it to the RIP. If your file does not have a layer named spot, you can add a white layer from the RIP. Preparing the job in the RIP In the RIP, choose the desired print mode. This selection places the white layer defined in the application into its desired position: Over, Under, or Spot (at the same level as the color layers). Assigning a print mode with white ink to a job with no white layer will cover the whole printing area with white. When ready, send the job to the printer. Selectable options and their effects Option Effect Overflood: White ink is printed on the substrate, enabling you to print color on top of a nonwhite or translucent substrate. Underflood: The white layer is printed on top of the color layer, enabling you to create new colors by playing with white ink translucency. This is used to print on transparent substrates such as acrylic, transparent film, or glass. Spot: White ink is printed in the same way as any other color. Sandwich: A white layer is embedded between two different images, allowing a different image to be seen on each side of the shape. Preparing a white job in your design software 121

Automatic white-ink maintenance cannot occur when the printer is completely turned oﬀ; and the white-ink

printheads cannot survive for more than 8 hours without maintenance.

Preparing a white job in your design software

Prepare the job using layers. Before sending it to the RIP, you should ensure that the part of the image to be

printed in white is on a separate layer named

spot

: a name that the printer will recognize.

When the image is ready, send it to the RIP.

If your ﬁle does not have a layer named

spot

, you can add a white layer from the RIP.

Preparing the job in the RIP

In the RIP, choose the desired print mode. This selection places the white layer deﬁned in the application into its

desired position: Over, Under, or Spot (at the same level as the color layers). Assigning a print mode with white ink

to a job with no white layer will cover the whole printing area with white. When ready, send the job to the printer.

Eﬀect

Overﬂood:

White ink is printed on the substrate, enabling you to print color on top of a non-

white or translucent substrate.

Underﬂood:

The white layer is printed on top of the color layer, enabling you to create new colors

by playing with white ink translucency. This is used to print on transparent substrates such as

acrylic, transparent ﬁlm, or glass.

Spot:

White ink is printed in the same way as any other color.

Sandwich:

A white layer is embedded between two diﬀerent images, allowing a diﬀerent image

to be seen on each side of the shape.
