There are three distinct regions that are cru-
cial to quality printing: Shadows, Midtones,
and Highlights.
SH a d O W S
e Shadows are the darkest regions of
the image, where halftone dots are largest
and risk blending together.
On a tint scale of [0..100%], shadows would consist of (roughly) the `
[85..100%] tint region of the image.
e challenge with shadows is that the dots blend together and obscure `
the darkest details of the image.
Hi g H l i g H t S
e Highlights are the lightest regions of the image, where halftone dots are smallest and appear
spaced apart.
On a tint scale of [0%..100%], highlights would consist of (roughly) the `
[0..15%] tint region of the image.
e challenge with highlights is that the individual dots, when used to `
expose emulsion, can be inadvertently washed away with the unexposed
emulsion.
It is often difficult to retain dots in the 5% range, and there are often `
challenges with any dots less than 10% tint.
mi d t O n e S
e Midtones are the mid-range regions of the image between the shadows and the highlights.
On a tint scale of [0%..100%], midtones would consist of the ` [15..85%]
tint region of the image.
For midtones, the individual dots will vary according to the image details. `
A concern with midtones can occur when too much ink has been ab-
sorbed by the substrate, such that image details are lost (e.g., the detail in
a person’s hair, or the texture of a grassy field).
