The Gripping Window is used to help you accurately grip tonal layers ahead of going to production.

There are several specific settings that need to be considered when gripping tonal layers.

• Reduce edges by - controls the size of the tonal steps between each pixel gripped so that a softer, faded grip can be achieved. This function acts differently with Standard and Circular / Rectangular mode. For example, if a design with a 100% tone edge is set to Reduce edges by 20%:

Using Circular / Rectangular mode, the edges reduce by the following percentages: 100% 80% 60% 40% 20%.

Using Standard mode, the edges reduce by the following percentages: 100% 80%, 63.92% 50.98%.

• Don’t reduce below - determines the minimum tonal value of the gripped edge
• Start Edge - lets you to specify the start edge tone of the grip
• Blur edges - tonally gripped edges can be blurred to smooth out the faded edges. Stepped effects can be avoided and the tonal fade can be made less noticeable.

It is important to note that blurring will change the tonal levels of the grip. For example, starting from a 100% edge and reducing edges by 20%, the third pixel out will not be exactly 51.2% in tone, as it would be if the edges were not blurred.
