New image- and 'blend'-editing and correction features are being added to PitStop Pro 12, the forthcoming release of Enfocus' PDF preflight and correction software. Developer Enfocus says that PitStop Pro 12 enables users to fix last-minute problems in seconds, and improves the efficiency of PDF editing workflows dramatically.

Image curve editing enables the user to work on the entire image or on individual separations, depending on the required colour correction. They can make adjustments to the highlights, quarter tones, or shadows. Extra curve control points can be added to a curve to make more precise adjustments, or the input and output percentage values of a curve control point can be adjusted using precise values.

The new Brightness/Contrast adjustment option in the Inspector allows the overall image brightness and/or contrast to be adjusted to increase the quality of the selected images. Unsharp Masking can selectively sharpen any or all images, with standard controls for amount, radius and threshold of the effect.

Existing 'blends' (ie shading, gradients and vignettes) within a PDF can now be adjusted and corrected, or deleted and replaced. Existing fills or strokes can be converted to a blend, and replacing a blend with a newly created blend to eliminate banding in the original is also possible. This new tool includes features to change the start/end points of blends, change the rotation of the blend, switch between linear and radial gradients, add new control points and colours, and change blend colours.

Edits to image colour curves can be recorded as Actions and can be used for automatic correction. Unsharp Masking and Brightness/Contrast are also available as Actions for automatic adjustment of images. These Actions can be incorporated into Action Lists.

Pitstop Server 12

The server version of PitStop 12 will be able to apply pre-set image enhancement Actions, and also gains the industry-standard Adobe transparency flattening engine as well as true 64-bit operations, for greater memory access.

PitStop Pro 12 and PitStop Server 12 will be released in September 2013. Beginning immediately, users purchasing or upgrading to PitStop Pro / Server 11 now will be entitled to a free upgrade to PitStop Pro / Server 12, until the actual release date.
