GLOSSARY OF PRINTING TERMS
Aqueous Coating (AQ Coating)
A clear, nontoxic finish used to add brilliance and durability to many products. Aqueous coating is not as durable or glossy as UV coating.
The amount of information that can be transmitted over a network such as the Internet in a certain amount of time.
The smallest unit of measuring information on the computer. A single bit can only hold two values, 0 and 1, by combining bits together you can get more information.
When an image extends off all four sides of the printed area without a border. If you want the image to extend to the edge of the paper, then we must cut 1/8 inch off the printed original to allow for the tolerance of the printing process. Design full-bleed projects with the cutting process in mind.
The area between the edge of the image and the edge of the paper.
In order to receive postal discounts, your mail must be grouped according to postal zone, boxed in special containers according to postal standards. A bar-coded label attached tells the post offices equipment where the mail piece goes.
The process of preparing and sorting mail to qualify for reduced postage rates. The lowest postage rates are available if you sort and automate the addresses on your mailing list. Bulk-Rate postage is lower than First-class, but Bulk-Rate has a longer delivery time.
A measurement of digital data capable of holding a single charter. 1 byte=8 bits.
Originals for a printing job that are prepared such that the printer can scan and print.
CASS (Coding Accuracy Support System)
A service offered to improve the accuracy of address matching. CASS software will diagnose and correct any problems to ensure delivery point is correct.
Papers that have clay slurry applied to their surface. These papers can range from extremely shiny to very dull. The chief benefit of these papers is that less ink is absorbed into the paper making for brighter colors and greater detail. Glossy papers are all coated papers.
A paper coated by a process that creates a very glossy surface on the paper.
An older but still common way of addressing, computer printouts of each address are made and then fed into a machine which cuts them into individual labels and glues them to each piece.
CMYK (Cyan, Magenta, Yellow, Black)
The standard color model used in the printing process. These are the colors referred to in "four color printing".
A standard used to compare color accuracy of an image for output.
Adjusting an image to improve overall output color.
The process of separating CMYK into film layers, each layer is than printed separately one on top of the other to give the impression of full color.
An unlimited range of color and shades of grays.
An image with light tones (highlights) and dark tones (shadows).
A message is given to a web browser then stored as a text file called cookie.txt. These files contain information to identify you as the user and enable both our ordering system and My PsPrint.

To trim or remove unwanted portions from the image in order to make it the proper proportion for your job.
A small mark outside the printed area used to show how a product should be cut.
A process where a digital image files is converted into CMYK bitmaps (ripped) and burned directly into the plates by a laser, eliminating the costly and environmentally questionable film step.
This is a process where no film is used. A job will go direct to plate and then print eliminating an extra step, producing better quality.
Dot Pattern—A series of dots that make up a printed image.
DPI (Dots Per Inch)
A measurement of how many dots can fit into one inch. The higher the amount of dots the sharper the image will be.
A halftone that prints in two colors to create greater visual interest or more subtle detail and gray tones.
EPS (Encapsulated Postscript File)
A file format for high-resolution images that is often used when you need to be move an image from one program to another.
Three-digit designations at end of a file name that tell the computer what format the file has been saved in. (Examples: .doc, .txt, .pdf, .psd)
Each different type of file has a different file format. A file format specifies how information is organized. (Examples: .doc, .txt, .pdf, .psd)
The process by which full-color photographs and artwork is reproduced. Four halftones —one for each of the primary colors, plus black —are printed one on top of the other, creating the range of color that was in the original.
FTP (File Transfer Protocol)
A protocol or method used to tranfer or copy files between computers over the Internet.
A printing process whereby multiple jobs are run on a single large
sheet of paper.
256 levels of gray from black to white.
The way that tints or grays are printed is by breaking the solid color down into a pattern of dots so small that they cannot be seen by the unaided eye. When this technique is used to created a uniform area of lighter color, it is called a "screen tint." When it is used to reproduce a photograph it is called a "halftone."
High Res—The resolution of an image indicates the number of dots per inch (dpi). High resolution is usually anywhere from 300 dpi to 2,500dpi.
A system that takes digital design file and produces film negatives that older processes require to make the printing plates. Sometimes this is referred to as Lino, after one of the first brands of imagesetters.
A type of printer that works by spraying ionized ink at a sheet of paper. Inkjet printers are capable of producing high quality print resolutions up to 2400 dots per inch. Newer models offer even higher resolutions.
JPEG (Joint Photographic Experts Group)
A file format used for color images. It retains a higher degree of color and files are smaller. Uncompressed JPEG can be used for high-quality printing.
A measurement of data equal to 1,024 bytes.
The number of dot lines created per inch, or lines per inch (LPI).
The resolution of an image indicates the number of dots per inch (dpi). Low resolution is usually anywhere from 72 dpi to 250 dpi.
See Line Screen.
This is a process used to delete unwanted areas of an image while maintaining its shape.
A color proof made from the printing negatives for a four-color process piece. This is the most accurate color proof available for analog presses.
A measurement of data equal to 1,024 kilobytes.
A piece that is handmade by the graphic artist to better show you how your finished piece will look. It generally will be folded and bound the exact way it will be done in production. Sometimes also referred to as a "comp".
An undesirable result in an image when a texture or screen is placed one on top of another. The image will appear fuzzy or wavy.
A reverse of an image created when processing film. Dark areas will appear light and light areas will appear dark.
Also called Offset Printing it is a process in printing where ink is spread on a plate then transferred to paper by using a blanket and pressing down.
See Offset Lithography.

A popular way of formatting documents so they can be viewed and printed on multiple platforms without changing. PDF is a modified Postscript format developed by Adobe as a standard for the web and for printing.
An image displayed on a computer is made up of lots of dots called pixels. A number of pixels displayed is referred to as the image's resolution.
