Grip Check allows you to check the grips in your designs as part of your quality control process. It can be done on individual layers or several layers at one time. This feature works by checking a specified grip amount and then produces a layer indicating the areas that do not meet the grip specification.

In our example, the dark purple layer has been gripped to the light purple layer so that the effects are clearly visible.

Activate the layer which you want to check the grip against, ie a layer that was adjacent to the layer that was gripped and not the gripped layer itself. In this example we will activate the light purple layer. You can activate more than one layer if you need to. Just be aware that you must not activate the layer which had the grip applied to it.

Make the layers visible and select the Grip Check tab in the Gripping Window.

Specify the number of pixels or other unit to check for and click on Grip at the bottom of the window.  A new 1 bit layer will be created which shows any areas where the grip is less than the specified amount.

In the example below, the original grip was 6 pixels but during quality control, it was noticed that some of the gripping had been damaged in some last minute editing.  Therefore, to identify the over gripping areas which are no longer 6 pixels wide, a grip check of 6 pixels is used.

The new layer can be used like any other layer. Therefore, if the grip check reveals any areas which did not grip as required, they can be moved to the correct layer. This can be done with the Mover Tool, or by copying and pasting from the grip check layer to the correct spot layer.
