Chapters 1, 2, &3

Finishing Processes: Finishing Processes are any actions taken to "finish" a job, these can include folding, embossing, die-cutting, trimming, and binding, as well as a few lesser known finishing processes.

Folding Dummy: A folding dummy is a mock-up of a proposed job. They are annotated and positioned to allow the designer an idea of how the printed pages will be aligned and joined together. Folding dummies prevent many common errors associated with printing; upside down images, continuity issues, incorrect ad or article placement, just to name a few.

Imagesetter: An Imagesetter is similar to a scanner, except instead of scanning an image and printing to paper, it scans an image and creates film, plates, or photo-sensitive paper. An image setter uses a dedicated RIP (raster image processor) to scan images, this is usually done at 1300 - 2500 DPI (dots per inch).

Pica vs Point: Picas and points are increments of measure used in printing and layout. Specifically Typographical layout.
Pica: A pica is 1/6th of an inch.
Point: There are 12 points in a pica, so a point is 1/72nd of an inch.

Die Cutting process: The die cutting process is the act of cutting, scoring or pressing a substrate with a design or blade to create a fold, perforated edges, or embossing.

Importance of Registration: The importance of Registration can mean the difference between having a well made product or spending time, energy, and money to produce it again. Registration is the act of lining all layers of a job to coincide, often this is done with special registration paper with pre-made holes and markings that line up to dowels and clips on the image setter.

Purpose of a RIP : The purpose of a RIP is to scan an image and create a rasterized bitmap from it, also RIPs can create bitmaps from Vector-based Images.

Define VDP: VDP (also known as Variable Data Printing) is a printing process that allows the producer to specialize the product for the end-user. An example of this is a direct mailer that may include an offer for horse back rides or massage therapy, the VDP aspect would use a database and produce ads for Horse back rides to certain people, and massage therapy to certain other people, depending on the database requirements. It is also used to direct market, by name, to recipients.

Two color print job : A two color print job is a job that uses black ink and any other color ink to produce visually stimulating artwork.

DPI, LPI, PPI: Units of measurement, and can vary from industry to industry.,
DPI: Dots-per-inch: DPI is generally used for output devices, such as printers, who use dots of color to print a job.
LPI:Lines-per-inch: LPI is used for offset printing, it relies of a grid pattern of different sized dots, each attracting ink to create halftones that simulate shades of colors.
PPI: Pixels-per-inch: PPI refers to the true resolution of an image as viewed on a monitor. This is the basis for all raster based images, the more original pixels in an image, the better the quality.

CMYK vs Spot Colors:
CMYK: Cyan, Magenta, Yellow, and Black. These are the basic colors of process printing, mixing them together in varying degrees produces all (or most) of the colors of the visual spectrum.
Spot Colors: Spot colors are specially mixed inks that produce the same color from any machine that uses them. There are many brands of spot colors, but Pantone is the most widely used.
