Abstract

This invention is for LFP Design Page Wide XL 5000/8000 Blueprint which is a Page Wide XL SKU designed

for blueprint peak users. Typically blueprint plots are printed with cyan and magenta, but additionally

Page Wide includes black to allow blueprint customers print in black and white as well. The most intensive

blueprint users print in “digital blue” (cyan and magenta) and hardly ever in black and white. This very low

black usage could cause reliability problems in black ink channel.

For that case those users hardly ever use black to avoid reliability problems is very recommended

exercises black nozzles. The new idea is adding black dots in blueprints to increases black nozzles usage

preventing reliability issues. This new way to combine inks to print in blue, provide higher optical density

and increases nozzle robustness against reliability issues.
