Against the Grain
Perpendicular to the direction of the grain in the paper . When a product gets printed against the grain, the flexibility of the paper can be thicker or thinner. Also called across the grain and cross grain. See also Grain Direction.
A defect which occurs when a graphic file does not have enough resolution to reproduce image detail and causes visible jagged lines along the edges.
Any change made by the customer after copy or artwork has been given to the service bureau, separator or printer. The change could be in copy, specifications or both. Also called AA, author alteration and customer alteration.
Technique of filling the edges of an object with pixels to eliminate jagged lines and make it appear smoother.
Aqueous Coating (AQ)
It is used to protect and enhance the printed piece. Aqueous coating is applied to all 100lb gloss book and 100lb gloss cover.

Usually refers to the joining of leafs or signatures together of multi-page printed jobs, with either wire, glue or other means. Examples of jobs that are bound include some calendars, books, and catalogs.
The processes that takes place after the printing has been complete. This includes cutting, scoring, folding, drilling, collating, stitching, and gluing.
Computerized image made up of a collection of dots or pixels; these images appear blocky when you zoom in; also known as raster images.
In offset printing, a blanket is a rubber-surfaced fabric that is clamped around a cylinder. The image is transferred from the plate to the blanket, and once the sheet is fed through the press, the blanket is what transfers the image to the sheet.
Printed colors that extend past the edge of a page. To cut the job to its actual size the processor has to make sure the job gets printed with 1/8 of an inch bleed some jobs may require more than that. For example if the job is a business card (3.5" x 2") the file size with bleed would be (3.625" x 2.125").
An outline around graphics, text or edge of a sheet. Read our guidelines on borders. Brightness: Refers to the percent of light reflected back from a sheet of paper as measured by a light meter reading. Contrast is reduced and highlights are not as strong when paper with a lower brightness is used for a printed piece. Depending on paper brand the papers have different brightness grades.
Paper coated on both sides. Our 14pt and 16pt paper are examples of C2S. (AQ Coating or UV Coating are seperate options and are not effected by this)

C: Cyan (Blue)
M: Magenta (Red)
K: Key (Black)
The mixture of clay materials that are applied to paper to improve the smoothness of the paper's surface and improve ink holdout during the printing process. Examples are Aqueous coating (AQ) and UV coating. UV coating adds a gloss finish to the product and also improves the vibrancy of the printed colors.

Dots Per Inch (dpi)
A measurement of resolution of input, output and display devices. 300 dpi means that when printed, each square inch of your image will contain 90,000 pixels (dots), the higher the dpi (the more pixels per inch) the more crisp the printed image will be. Our electronic (digital files) have to have a resolution of at least 300 dpi. Anything less than that is considered as low resolution and may appear blurry when printed.
Finished Size / Trim Size

Customers get order numbers automatically when they place an order online.
Printing an image over an area that has already been printed. In printing process colors, one process color is printed over another creating a secondary color, which is a combination of two primary colors. Sometimes in the files that customers send us there will be overprinting issues. Such as type or logos not printing. Customers should be aware that we do not check for this and their overprinting situation must be evaluated before sending the files to us.
Overruns / Overs
The quantity of items produced over the quantity that was originally ordered. Also referred to as any paper spoiled in the process of printing. For example if our batch is 1000 quantity batch we always overrun 150-200 sheets.
Pantone Matching System (PMS)
A registered name for an ink color matching system used to compare, match and identify specific colors. To do so we use a pantone book. It contains pantone colors with their closest CMYK values.
The direction in which the fibers line up during the manufacturing process. It is easier to fold, bend, or tear the paper along the same direction of the fibers. Cut sheet laser printers generally use long grain paper in which the grain runs parallel to the long side of the paper, resulting in better performance through the laser printer.
Creating a series of holes so that the paper can be torn more easily along the line that is formed. Postage stamps and tear-off cards are common products that require perforation.
The smallest unit of a digitized image created by a digital device, such as a computer, camera, or scanner. Pixel is short for "picture element." The more pixels per inch the better the resolution. On computer monitors, the display is divided into rows and columns containing thousands or millions of pixels. Each pixel is composed of three dots representing the three color channels of red, green, and blue light that are necessary for creating a color image on computer monitors and television screens. Because of their small size, the pixels appear to merge, simulating a continuous tone image, but when magnified they appear to be tiny square blocks of light, as shown in the illustration.
Payment for delivery service that is affixed or imprinted to a mail piece, usually in the form of a postage stamp, permit imprint, or meter stamp.
Inner pocket with round cut corner: (1 or 2, left & right pockets are optional) Inner pocket with straight cut corner: (1 or 2, left & right pockets are optional) Business card slit, left or right is also optional.

To render an image, pixel by pixel, vertically and horizontally.
The printed marks used to align color separations for printing so that each color registers with each other.
The measurement of output quality expressed in pixels (dots) per inch on a computer monitor or dots per inch on printed media. For example, a monitor displaying a resolution of 800 by 600 refers to a screen capable of displaying 800 pixels in each of 600 lines, which translates into a total of 480,000 pixels displayed on the screen. When referring to printed media, a 300 dpi (dots per inch) printer for example, is capable of outputting 300 dots in a one-inch line, which means that it has the ability of printing 90,000 distinct dots per square inch (300 x 300).
The additive primary colors, red, green and blue, used to display color in video monitors. Printing with a file in RGB color mode will produce a washed out appearance. 4over does not check files for RGB. That responsibility falls to the customer before submission of the files.
