– Set the Halftone setting in the Image Setting dialogue to Standard
for printing. The image will be coarse, but the ink will transfer to
the paper more reliably.
– If you have VPhoto Primer ink, the image quality may be improved
by providing an undercoat.
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.
– 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.
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 Can I print on overhead transparencies using foil cartridges?
Printing is possible, but the foil ink is not transparent.
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.
