Oki DP-5000 manual Ink and paper, How should I use white ink? White ink can be used as follows

5When plain or other coarse-surfaced paper is printed in colour, ink is missing from a number of points on the image.

When paper with a coarse surface is used for full colour printing, ink will be missing from certain points where it was difficult to deposit. To correct this, you can attempt the following.

a Set the Halftone setting in the More Set- tings dialogue box to Standard Dither for printing. The image will be coarse, but the ink will transfer to the paper more reliably.

b If you have VPhoto Primer ink, the image quality may be improved by providing an undercoat.

6When coloured paper is used for full colour printing, the colours are not reproduced correctly.

Colour printing is based on the colours repro- duced when ink is printed on white paper, so cor- rect colours cannot be reproduced on coloured paper. DP printers, however, can provide the fol- lowing 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

English

tones close to those obtained by printing on white paper.

bOn dark-coloured paper, impressive finish- ing may be obtained by using monochrome printing with white ink.

7Colour images in the same document look different.

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

1How 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.
