Crusial ConceptsPress run: press:to print, run: the continuous period of time during wich something(a machine or factory)operates.

Layout:(noun) the art or process of arranging printed or graphic matter on a page.

"folio" :is used in terms of page numbering.

On-the-fly imposition: common terminology, "on-the-fly" means "in a hurry" the rest is implicitly defined.

Bound work: refers to the binding method or binding style, which is the way the final papers are going to be bound or joint together to create the final output as a book. there are several styles, some of the most popular are: perfect binding, saddle sticht, cut and collate.

Signature: refers to the group of pages that are printed on the same sheet of paper.

"Bleed":(sangría)It is often necessary to have images and other design elements extend all the way to the edge of your printed page. If in your layout these elements only extended to the edge, and not beyond, you would risk a tiny bit of white space showing up on the edge of your paper if it was not cut exactly on the trim marks. For this reason, you have bleeds. Bleeds are images that extend beyond the live area of the page (and beyond the trim marks) to guarantee clean edges. Background colors are an example of a common use of a bleed.The amount that your images need to extend beyond the trim marks is referred to as the bleed. Be sure to consult your printer at the start of a job to find out the required amount of bleed, which is often around one-eighth of an inch. In your graphics software, you can use guides to mark your bleed area, which do not need to show up in the final document that you deliver. Just make sure any image that needs to extend to the edge of the page actually extends to your bleed guides.

"Trim Marks":(líneas de corte)Trim marks, or crop marks, show the printer where to cut the paper. For a standard layout, such as a business card or poster, trim marks are small lines located in each corner of the document. One line shows the horizontal cut, and one shows the vertical cut. Since you don�t want these lines to actually show up on your printed piece, trim marks are placed outside of the final visible, or �live,� area.

"Trimmed page size": The trimmed page size is the final intended size of your pages, after being cut along the trim marks. This size is important to supply to the printer because it will determine what machines will be used to print your job, which will affect the final cost. When starting a project, the size you create your document at in a graphics program is the trimmed page size.

"creep":Is the extra extended space(alone the spine of a folded paper) between faces of the same sheet to ensure the nice fittig when several sheets are fold a putted together in order to create booklets.

"Offset":Is the distance of all printer�s marks from the edge of the artboard. The trim marks are at the edge of the space determined by the offset.

Number_up imposititions: a common terminology, reffers to the imposition in wich the "Number_up" represents the number of pages(final design pages) printed in one of the front and back of the sheet paper.

Gange run printing: common terminology, often related as "ganged works, ganged j

obs, etc", describes a printing method in wich many printing projects are place into a common paper sheet in an effort to reduce costs and paper waste.
