Abstract
A printing device includes a first array of dot forming elements disposed on a substrate along an array direction at a first array-direction spacing to provide a first dot forming resolution R1 for dots of a first color; and a group of N arrays of dot forming elements, wherein the dot forming elements in each array of the group of N arrays are disposed on the substrate along the array direction at a second array-direction spacing to provide a dot forming resolution equal to R1/N; at least one of the N arrays of dot forming elements forms dots of a different color than at least one of the other arrays of the N arrays in the group; and N is greater than 1.

A printing device, comprising:
- a first array of dot forming elements disposed on a substrate along an array direction at a first array-direction spacing to provide a first dot forming resolution R1 for dots of a first color;
- and a group of N arrays of dot forming elements, wherein:
- the dot forming elements in each array of the group of N arrays are disposed on the substrate along the array direction at a second array-direction spacing to provide a dot forming resolution equal to R1/N;
- at least one of the N arrays of dot forming elements forms dots of a different color than at least one of the other arrays of the N arrays in the group;
- and
- N is greater than 1.
A printing apparatus including a first printing device and a carriage for moving the first printing device during printing, the first printing device comprising:
- a first array of dot forming elements disposed on a substrate along an array direction at a first array-direction spacing to provide a first dot forming resolution R1 for dots of a first color;
- and a group of N1 arrays of dot forming elements, wherein:
- the dot forming elements in each array of the group of N1 arrays are disposed on the substrate along the array direction at a second array-direction spacing to provide a dot forming resolution equal to R1/N1;
- at least one of the N1 arrays of dot forming elements forms dots of a different color than at least one of the other arrays of the N1 arrays in the group;
- and
- N1 is greater than 1.
A printing device comprising:
- a first array of dot forming elements disposed along an array direction at a first array-direction spacing to provide a first dot forming resolution R1 for dots of a first color;
- and a group of N arrays of dot forming elements, wherein:
- the dot forming elements in each array of the group of N arrays are disposed on the substrate along the array direction at a second array-direction spacing to provide a dot forming resolution less than R1/2;
- at least one of the N arrays of dot forming elements forms dots of a different color than at least one of the other arrays of the N arrays in the group;
- and
- N is greater than 1.
