Frequently asked questions
Why is photocopied colour text sometimes unreadable?+
Colour text on a coloured background may have similar greyscale values, causing poor contrast when the copier converts. Pre-converting forces an intentional greyscale mapping.
Does this work for printed forms with coloured fields?+
Yes — coloured form fields will convert to appropriate grey tones, remaining visible without colour.
Will halftone images in the PDF reproduce well?+
Greyscale conversion improves halftone reproduction by ensuring correct tonal range before the copier's own conversion process.
