Detect missing bleed and fix it with PitStop Pro 13


Welcome to an advanced preview of PitStop 13 which will be released in April of 2015. The following video is one in a series
of clips designed to showcase what new and
existing users of PitStop Pro can look forward to in our upcoming
release of PitStop 13. The subject of this video is the new and
improved Action List “Add bleed”, which can now create bleed for
both vector shapes and raster or image data when this
material is either insufficient or simply not present within a
supplied PDF file. Before examining the technical properties, allow me to demonstrate just how easy this Action List is to use in real-world situations in
which supplied files have arrived with no bleed. While it is possible to perform automated Preflight checks for proper bleed box assignment and for adequate object-based bleed, we’ll take a moment to manually examine the necessary components for bleed, which will help us to describe how the
new and improved Action List works and will also help new users to have a
better grasp on what goes into a file with proper bleed configuration. Files need two basic elements for proper bleed. First: a properly defined bleed box. And second: objects that are intended to
run to a page edge must be extended past the trim box
to the edge of the bleed box. Our first example file immediately shows
visual signs of concern since information appears to abut the
crop marks. To further validate this concern: if we
enable the PitStop page box view you can see the trim box in dark blue
and the bleed box in cyan, but no page data between these
two sets of guides. Finally, if we switch to the PitStop
wireframe mode, our concern is indeed valid. Not only is
there no information in our bleed box area, objects show no signs of any additional information which may have been hidden or masked and
potentially used for bleed. This particular design, as with many,
leave little option for production as enlarging objects to create bleed
would produce unwanted results. Historically this file would be unusable. Production would cease until new files with appropriate bleed arrived. Running the “Add Bleed” Action List quickly and
effectively adds both vector and raster bleed to a
file which previously had none, and so production resumes. A second
sample file depicts a very similar scenario and as we check the same criteria, we
first visually notice the lack of bleed in relation to the crop marks. When engaging the page box view, notice
that this space is empty. And lastly, in PitStop wireframe mode there is clearly no hope to produce
bleed using this file as is. Enlarging objects will again yield a
compromise design, so we’ll execute the “Add Bleed” Action
List and review our results. Once again our page is now correct and
production can continue. Let’s now look at how the Action List works. In situations where content is available to generate bleed, PitStop will detect this and create bleed
to fit the size of the bleed box. For this reason it is important to
ensure that a given document has a bleed box present and that it is
sized accordingly to provide the required amount of bleed. In other words, information that was
masked by the originating application at the time the PDF file was made. In our third example file you’ll see that this file differs from our previous examples in that the wireframe mode shows that
this file has usable data that is currently masked on the left
edge and bottom. This file also contains no bleed on the
right edge and at the top. PitStop will simply reveal these
masked areas exposing the information for bleed. When PitStop encounters a PDF file with no available bleed, it will now use a mirroring technique to
generate sufficient bleed. The newly created mirrored object is
kept independent from the original image but is an exact copy of the original, retaining all attributes, such as overprint, ICC
profile tagging, and color space for example. These objects can be edited or deleted
if necessary. To more clearly illustrate the mirroring
technique used by PitStop to generate bleed, we’ll execute the “Add Bleed” Action List on a file which contains all image
color spaces available in a PDF file. It has grayscale, spot color monotone, a duotone, tritone RGB, CMYK, LAB, a multichannel image of CMYK, and two spot colors. This page is also missing bleed. After executing the “Add Bleed” Action List, you can now see I have bleed and if I now go to the output preview
and turn off the black separation you can see that my generated bleed has the same color separations as my original content. If I turn off the
other process colors cyan magenta and yellow, you can see the
separations are as you would expect. As with any
adjustments made to a supplied file, you’ll need to examine the results to
ensure that the effect is acceptable and will not compromise the content. Thank you for watching! We hope that you found this video useful and be sure to watch all the videos in this series as the excitement builds leading
towards our latest release of PitStop Pro version 13.
