Trapping refers to how much overprinting colors overlap to eliminate white lines between colors in printing. Trapping digital files are used for compensating for misregristration on the printing press by printing small areas of overlapping color. Dry trapping is printing wet ink over dry ink. Wet trapping is printing wet ink over previously printed ink. The paper or plate applying the ink may shift. It may be 1mm shift but this can throw off your design enough to be noticed depending on the product you are printing. When will you use trapping? When you are printing 2 diffenent colors that overlap they "knockout". They will not print on top of each other. Knockouts may require trapping so there are no color gaps or white spaces where they are not suppose to be on your final product. When using trapping you also need to know how to set the trap depending on the number of overlapping objects, imported images, and the use of gradient fills need to be taken into consideratio

Media: Files can be submitted by 3.5" floppies in some print shops. Check with shop before using. The most commonly used are zip or jaz files. There is also Bernoulli and recordable cd's. Electronic File Transfer (EFT): Files can be submitted via e-mail, File Transfer Protocol (FTP) and by modem. EFT's may not be practical choice if you are sending a large file and may take a long time depending on the type of internet connection you are using.

What is Prepress? Prepress is a term used to describe the process used to make a document ready for print in any environment. screening (eg. with photographs) copyediting type (kerning, widows, orphans) proofreading (spelling, page layout, document size, bleeds, gripper edge) retouching (modify or correct photographic images) imposition (layout of pages so that after folding, collating, printing and trimming they all end up in the correct order and right way up) trapping ( creating an overlap between areas to compensate for any misregistration) color separation (make sure colors separate properly) and that your using proper colors if requires spot, cmyk or special pantone. In other words there are things that need to be done to get a file printed, either through laser or digital printing format. Proofreading, editing, layout, scanning and color separation are the major ones. Which should all be done before you send your files to the printer. Once you have gone through all of the s

DOCUMENT TO PRINT The layout of your document involves many aspects • Page Layout / set up • Color • Imports • Fonts • Resolution • Imposition & Folding • Bleeds • Ink coverage • Transparencies • Artwork & print format • Dpi • Converting files in photoshop, Illustrator, Corel for print/web PAGE LAYOUT • Always define your document page size to equal your final trim size. • You should always pull a bleed 1/8" beyond the page boundary if bleeds are not present on the film,    bleeds must be added and new film run or your document will have to be under trimmed. Lack of        bleeds is sometimes overlooked during pre-flighting of your document on the screen. Cutting can        only be accurate to about 1.5 mm when chopping small items like flyers. COLOR • Unless specified; all colour printing is full color and should be completed and saved in CMYK           process. Do not use Pantone or similar colors unless pre-arranged for specialist jobs. • RGB
