K
kerning
The space between characters, and the adjustment of that space. Often, kerning is used to place two characters closer together than usual,
for example WA, AW, TA, or VA. Kerning increases readability and makes letters appear balanced and proportional, especially at larger font
sizes.
knockout
A printing term that refers to an area where underlying colors have been removed so that only the top color prints. For example, if you print
a small circle on a large circle, the area under the small circle is not printed. This ensures that the color used for the small circle remains true
instead of overlapping and mixing with the color used for the large circle.
L
Lab
A color model that contains a luminance (or lightness) component (L) and two chromatic components: “a” (green to red) and “b” (blue to
yellow).
layer
A transparent plane on which you can place objects in a drawing.
leading
The spacing between lines of text. Leading is important for both readability and appearance.
lens
An object that protects part or all of an image when you perform color and tonal corrections. You can view the effect of a correction
through a lens without affecting the underlying pixels. If you move a lens, the correction is applied to the pixels at the new location.
linking
The process of placing an object created in one application into a document created in a different application. A linked object remains
connected with its source file. If you want to change a linked object in a file, you have to modify the source file.
lossless
A kind of file compression that maintains the quality of an image that has been compressed and decompressed.
lossy
A kind of file compression that results in noticeable degradation of image quality.
low-frequency areas
Smooth areas in an image where gradual changes take place. That is, areas where there are no edges or noise.
LZW
A lossless file compression technique that results in smaller file size and faster processing time. LZW compression is commonly used on GIF
and TIFF files.
