Finepoint Sharpening

Finepoint Sharpening uses a special rendering technique to produce sharp images with crisp edges and smooth color detail, for bitmap or scanned image data.
Details on Finepoint Sharpening
When the Finepoint Sharpening box is checked on in the driver, or the utility file is sent to the printer, your job is printed with a Tektronix- proprietary technique that uses fine points, or grain, to produce a smoother halftone pattern, and edge-enhancement processing to sharpen and define image detail. Bitmapped (rasterized) images printed with Finepoint Sharpening look sharper, with crisp edges and smooth color detail.
When the Finepoint Sharpening box is not checked in the driver and the printer's standard defaults are reset, your job is printed with the printer's current default halftone screen. The default screen uses Adobe's Brilliant Screens technology.
Finepoint Sharpening works best with natural images, such as scanned photographs, with lots of detail, texture, and muted (less intense or saturated) colors.
Bitmapped images must meet the following requirements:
- The edges of the bitmapped image must align with (or be parallel to) the edges of the paper. That is, an image can only be rotated in multiples of 90 degrees, and it can be inverted or mirrored.
- The bitmapped image must be rectangular.
- If you specify a clippath shape (also called clipping path, mask, or
masking) around an area in an image, it must be a rectangle and the edges
of the clippath must align with (or be parallel to) the edges of the paper.
You may want to turn off Finepoint Sharpening for some bitmap images
created in paint programs (such as pie charts and graphs with large areas
of solid primary colors), in the following cases:
- In images where small areas or narrow bands of color, with either very high or very low in intensity (or saturation), disappear or have rounded corners when printed with Finepoint Sharpening.
- In images with dramatic shifts in colors, for example, where an area of dark color is next to an area of light color, or where an area of highly saturated color is next to an area of lightly saturated color. With the Finepoint Sharpening option checked on, you may see some "ghosting" or shading between these different color areas.
