PRINTING USING A PLURALITY OF KINDS OF DOTS HAVING DIFFERENT FORMATION MODES WITH EQUAL AMOUNT OF INK |
摘要 |
<p>An ink jet printer has a specific unit that is capable of splitting a dot into a plurality of divisions. The arrangement of splitting an ejected ink droplet into a plurality of parts to create a split dot having a plurality of divisions at a plurality of different positions in one pixel advantageously decreases the quantity of ink per position. This reduces penetration of ink in the direction of the depth of printing paper. Under the condition of a fixed quantity of ink, the split dot has a greater total area than the area of a single dot and ensure a higher resulting expressed density. This arrangement ensures multi-tone expression without changing the total quantity of ink ejected in each pixel. <IMAGE></p> |
