CLAIMS

What is claimed is

1. A print system comprising:

a component device operational in a number of states;

a density engine to:

identify a piane region of a plane where print fluid is to be printed based on data of a print job;

determine a density classifier for the plane based on a location of the plane region on the piane; and

a component engine to cause an adjustment of a component attribute of the component device based on the density classifier.

2. The system of claim 1 , wherein the density engine:

determines whether print fluid data representing an amount of print fluid to place at a first tile within the piane region achieves a density condition;

assigns a value to the plane regio based on a relationship between a location of the first tile and a location of a second tile within the plane region; and

selects the density classifier based on the value of the plane region.

3. The system of claim 1 , wherein the density engine further comprises;

a topograph engine to maintain weights associated with page regions on a page, the page being the plane to receive print fluid based on the print job; and

a factor engine to identify an operational factor of the print system.

4. The system of claim 3, wherein the density engine:

computes a density score for the page based on a matri of weights that corresponds to the page regions on th page that achieve a density condition; and determines the density classifier based on the weighted density score.

5, The system of claim 4, wherein the density engine:

applies a modifier to the density score based on the operational factor; and identifies the density classifier using a lookup table with the page score as input.

8, The system of claim 3, wherein;

the factor engine identifies at least one of a page size or a page orientation; and the topograph engine at least one of:

selects a topograph based on the page size; or

selects the topograph based on the page orientation.

7. The system of claim 3, wherein:

the factor engine determines a stage of the page in the print path; and

the density engine adjusts the page score based on the stage of the page in the print path.

8. The system of claim 3, wherein:

the factor engine identifies an environment variable associated with an operational state of the print system; and

the density engine determines the density classifier based on the environmen variable.

9. The system of claim 3, wherein:

the factor engine identifies a job attribute associated with the page of the print job; and

the density engine determines the density classifier based on the job attribute.

10. A non-transitory computer-readable storage medium comprising a set of instructions executable by a processor resource to:

map print job data to a topographical representation of a plane to receive print fluid;

5 divide the topographical representation into a plurality of tiles, each tile of the

6 plurality of tiles comprising a number of pixels;

7 determine whether an amount of print fluid to be ejected at each tile of the

8 plurality of tiles achieves a density condition based on content placement identified

9 via the print job data;

0 determine a plurality of location-based density scores, each location-based 1 density score computed in response to a determination that a tile achieves the 2 density condition;

3 identify a plane score based on a relationship among plane regions associated 4 with the plurality of location-based density scores, the plane score representative of 5 a combination of the plurality of location- based density scores at the plane regions; 6 and

? cause a print device to adjust print speed based on density classifier

8 corresponding to the plane score.

1 11. The medium of claim 10, wherein the set of instructions is executable by the

2 processor resource to at least one of;

3 select, based on a job attribute, a set of topographical weights to apply to the

4 plurality of tiles that achieves the density condition; or

5 adjust, based on the job attribute, the set of topographical weights to apply to the

6 plurality of tiles t at achieves the density condition,

1 12. The medium of claim 10, wherein the set of instructions is executable by the

2 processor resource to at least one of:

3 map the plane score to the print speed within a predetermined range of print

4 speeds; or

s override the print speed based on a job attribute, an environmental factor, or a

6 printer state.

1 13. A method of adjusting operation of a print device comprising:

determining a plurality of plane regions of a page that are expected to receive a threshold amount of print fluid;

assigning a value to each plane region of the plurality of plane regions relative to a position of the each plane region on the page, the value associated with a print fluid density;

combining the value of each plane region to produce a page score corresponding to locations of the threshold amount of print fluid;

mapping the page score to a density classifier, the density classifier

representative of print fluid density at the plane regions; and

identifying an attribute level of a component of the print device associated with the density classifier,

14. The method of claim 13, comprising:

modifying a topographical weight applied to determine the value to assign to each plane region based on a print path stage or a job attribute;

modifying the page score based on a job attribute or an environmental variable; causing a component of the print device to change an operational state based on the density classifier and a position of the page in print path; and

causing a print speed of the print device to adjust based on the density classifier.

15. The method of claim 13, comprising:

determining a plurality of page scores, each page score of the plurality of page scores representative of an overall topographic print fiuid density for a consecutive page of a set of pages of the print job; and

adjusting a print speed of the print device based on the plurality of page scores.
