6 When coloured paper is used for full colour printing, the colours
are not reproduced correctly.
Colour printing is based on the colours reproduced when ink is printed
on white paper, so correct colours cannot be reproduced on coloured
paper. DP printers, however, can provide the following forms of
printing even on coloured paper:
– On light-coloured paper, DP printers provide a white undercoat
prior to colour printing. This allows colours to be reproduced in
tones close to those obtained by printing on white paper.
– On dark-coloured paper, impressive finishing may be obtained by
using monochrome printing with white ink.

Make sure that you select the same media type and print mode. The
media type presets the most suitable settings for your document. If you
change the media type or print mode, it will affect the printed results.
Ink and Paper
1 How should I use white ink?
White ink can be used as follows:
– As with foil ink, white ink is effective for spot colour printing on
dark-coloured paper.
– White ink can provide an undercoat for full colour printing on light-
coloured or coarse-surfaced paper. The white undercoat will
improve image quality and colour reproduction.
2 How should I use VPhoto Primer ink?
The VPhoto Primer ink prints an undercoat and improves the print
quality on most plain papers by allowing you to print photo quality
images at 2400 dpi using variable dots.
3 Is it OK to print using white ink on top of a full colour image?
This can cause unsatisfactory results. Print the white ink before using
other ink colours.
4 For full colour printing and glossy finish, may I use any type of
paper?
We suggest using High Grade Paper for full colour printing and glossy
finish. Using other types of paper can produce a poor image. Although
