Printing quality, hue, and resolution queries

1Can all four colours of the colour inks be combined for black and white printing?

In colour printing mode, greyscale portions are printed using a four-colour greyscale. Black char- acters are also printed using a mixture of the four colours, if brightness is adjusted. To print mono- chrome portions in black only, adjust the bright- ness to 0%. To subject the overall image to monochrome printing, set the Type Settings to

Black & White.

2Black is printed with black ink, but grey portions are printed using four colours.

In colour printing, greyscale intermediate colours (such as grey) are printed using four colours. If you want to print only in black ink, set the Type setting in the Print dialogue box to Greyscale.

3I would like to adjust the image quality of photographs without reducing character resolution.

Characters always print at the currently selected resolution (if an outline font is used). The image quality of photographs can be adjusted independ- ently using the Halftone setting in the Image Set- ting dialogue box.

4There seems to be no difference between photographic output using monochrome printing set to Fine and images obtained by monochrome printing set to Standard.

With monochrome printing set to Fine, only the characters can be printed at Fine. This is done by smoothing the Standard images. The quality of photographs, however, differs little from that of images obtained by monochrome printing set to Standard.

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 Image Setting dialogue to Standard for printing. The image will be coarse, but the ink will trans- fer to the paper more reliably.

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