Bleed and slug layout

The step from desktop printing to professional printing is not very big anymore. 
It would be nice to have bleed and slug settings for a page. 

Now you can only set margins in the page layout menu. If you do not have bleed edges you can not really use images that are as big as the page. Because usually in a print shop pages are cut to size after printing. If an image is full page size then you have a big risk of getting a white line or you have to cut below the A4 size which is not very nice. As a workaround you could make a page bigger than A4 and then correct with margins but that is a bit hackish.

Mmh, I'm not getting the clue of this bug report I guess.


So as far I understand, with no professional printing skills: you would like to have a full A4 image printed, without the chance of having little whitespace?

What if you do the following:

Format > Page > 'Page' : all margins to 0 cm; and in the same dialog but tab 'Background' option 'Graphic'.

Doesn't that apply an image to the complete area of the page? What am I missing here :-)?

If I may, I am a professional in print and can shed more light on this feature enhancement. First lets establish some background and go through what the terms 'bleed' and 'slug' mean to the print industry. 

Despite all of the engineering progress that has been made in print equipment till now, they are still imperfect. From one printed sheet to the next, the imprint can move on the sheet. This movement is unavoidable, but there are 2 approaches for print pros to account for the inaccuracy. One, is to design and print the document or piece with ample blank margin on all sides so when trimming to final size, a shift of a 1/16th in any direction is not easily noticeable. The other approach is to add bleed. This method is used when a piece's design (color, images, and/or text) are intended to butt up to the edge of sheet (no blank margin). In such cases, it is standard practice to extend those elements past the point where it will be trimmed, in order to guarantee that there will be no blank paper showing after being trimmed. This extra space is called bleed. The industry standard bleed distance from the trim edge is .125" but is customary in design software to allow the user to define their own bleed distance on each side independently or linked together.

The reason why either Maarten's or Jorendc's workaround suggestions wouldn't quite work well is because bleed definitions need to be accompanied by trim marks (also called cut or crop marks). These marks print with the document and visually indicate to the trimmer operator where to cut the sheet to final size. Also they would have to use another workaround to defining margins b/c they are essentially turning those off. 

Next, a slug is an area positioned outside the dimensions of the final print piece and outside the bleed space. This area will print along with the document on an oversized sheet and will later be trimmed off at the final stage of production. This space is intended to pass information or specifications to the production floor about the document itself. Designers typically have free reign to add whatever they want to the slug area and like a header or footer is able to persist to all pages or be edited individually per page.

Lastly, all of these components (bleed, slugs, and trim marks) are typically able to be enabled/disabled for printing via a toggle.

Hi Maarten and Andrew,

Bleed and slug can be achieved within the page style dialog using the margin values on the Page tab and the spacing to contents values on the Borders tab. So for example if we wanted to duplicate the layout in attachment 96407 [details], we'd set the margins to 0.5 inches, enable borders and then set spacing to contents to 0.5 inches. There isnt an easy means in the dialog to add a slug area border, so that would need to be create either with a rectangle shape, textbox, or frame. For even more control, a desktop publishing (DTP) application would better suit your needs and possible Libreoffice Draw could handle those requirements.
