The above is an excellent article, and everybody’s comments are relevant. In order to apply creep we “pull” (moving the offsets – increasing or decreasing the “x” co-ordinate) in towards the spine toĪllay the problem of the content of the publication from pushing out, and therefore also allowing the folios to back up. IE, as we work with finished pdf’s as supplied from the publisher or designer etc, the files, therefore, do not belong to us, and we do not alter them. Once this is achieved, we then apply various “creeps” to the different sections of the publication, depending on where the pages lie in the book or magazine. The thickness of the finished article needs to be worked out. In commercial heat offset print, we normally work out the bleed required, based on what type and weight of paper the publication is being printed on. It is all very well bleating to the customer and the csr about requiring less or extra bleed. In my own experience, most of the designers out there do not seem to understand all that is required for the print processes. I am a Prepress workflow operator, and have worked for the last 10 years in Kodak Prinergy Preps. I have read the article and also everyone’s comments on this subject of bleeds. The fact that this makes the pages smaller than they should be is not always an issue.

As long as it are simple objects that need to bleed, using an editor like PitStop to edit a PDF is a lot of work but still doable.First of all the bleed box may need adjusting.For PDF files, things are a bit more difficult:.Changing bleed in native files is the easiest, as long as you have the matching application at your disposal.Not all applications support bleed and not all designers are aware of the need to extend content beyond the page edge.
#EDGE MARGINS PDF PLUS HOW TO#
How to edit bleed or add it to a document? Activating this option makes the resulting PDF file smaller but it also makes it very difficult for a prepress operator to tweak bleed settings afterward if you didn’t use (enough) bleed.
In InDesign, this option is called ‘Crop Image Data To Frames’ in the Compression tab of the PDF Export window. Some applications allow you to crop images to their image frame when creating a PDF. This will be shown as an extra guide around the page.
#EDGE MARGINS PDF PLUS PROFESSIONAL#
To make a designer’s life easy professional design applications like Adobe InDesign allow you to specify the amount of bleed that is needed. The prepress systems used at the printing company can trim any excessive bleed but why cause problems that are so easy to avoid? Letting images extend beyond the needed bleed clutters the file, can lead to bloated PDF files and simply looks sloppy. The fact that content needs to extend beyond the page boundaries is no excuse for sloppy design.
Once the design of a job has been finalized, modifying bleed can be a real hassle so it is better to start off using the correct value. Contact your printer in case of doubt or look up their recommendations on their website. Many prefer a bit more bleed – 5 millimeters – especially for large books, thickish paper or jobs with many sections.īleed requirements can be different from one printing company to another and from one job to another. Generally, the bleed amount is set to 3 millimeters or 1/8 of an inch. If a small page number is put right at the edge of the page and that page is trimmed incorrectly, the page number may simply get cut away. To avoid such lines, the design elements have to extend beyond the trim edge of the page.Īctually all the reasons why bleed is needed also explain why small design elements should not be positioned too close to the outer edges of the document. If the page content exactly fits the page itself, such errors could cause a thin white line to show at one of the edges of the page. Paper is an organic material that may shrink when it is subjected to humidity and mechanical stress. To be able to move pages, you need the content to extend a bit beyond the trimmed page size.ģ. To compensate for this effect, the entire content of pages is shifted slightly to the left or right, depending on production needs and the design of the content.
