6 When coloured paper is used for full colour
printing, the colours are not reproduced correctly.
Colour printing is based upon the ink being
printed on a white background, so correct colours
cannot be reproduced on coloured paper. DP
printers, however, can provide the following
forms of printing even on coloured paper.
a On light-coloured paper, DP printers pro-
vide a white undercoat prior to colour print-
ing. This allows colours to be reproduced in
tones close to those obtained by printing on
white paper.
b On dark-coloured paper, impressive finish-
ing may be obtained by using monochrome
printing with white ink.
Ink and paper
1 How should I use white ink?
White ink can be used as follows:
a As with foil ink, white ink is effective for
spot colour printing on dark-coloured paper.
b 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 reproduc-
tion.
2 Can I print on overhead transparencies using foil
cartridges?
Printing is possible, but the foil ink is not trans-
parent.
3 Can I use the Dye Sub Overcoat cartridge for Glossy
finishing?
No. Always use the Finish II cartridge.
4 Is it OK to print using the white ink on top of a full
colour image?
This can cause unsatisfactory results. Print the
white ink before using other ink colours.
5 For full colour printing and glossy finishing, may I
use any type of paper?
We suggest using High Grade Paper for full col-
our printing. Using other types of paper can pro-
duce a poor image. Using our VPhoto Primer will
help make many plain papers suitable for full-col-
our printing.
