Glossary

4/0

Full color (CMYK) printing done on the front side with no printing on the back side.

4/1

Full color (CMYK) printing done on the front side with black or grayscale on the back side.

4/4

Full color (CMYK) printing done the front and back side.

Aqueous Coating (AQ)

This is available in gloss or dull. A clear, non-toxic, water-based coating applied like ink by a printing press to protect the printed surface.

Bindery

The processes that takes place after the printing has been complete. This includes cutting, scoring, folding, drilling, collating, stitching, and gluing.

Bleed

A bleed is when an image extends beyond the trim edge of the printed product. If your image is not white on all four sides, you MUST include bleeds in your files. Add 1/8" (.125") to each side of the file. For example, for a 4" x 6" postcard with full bleed, the image size should be submitted at 4.25" x 6.25"

Blind Embossing

A technique in which a design is pressed into a sheet without ink or foil, creating a raised image.

C1S (Coated One Side)

Abbreviation for a type of paper that is coated on one side, and not on the reverse side.

C2S (Coated Two Sides)

Short for a type of paper that is coated on both the front and back surface of the sheet.

CMYK

Abbreviation for Cyan, Magenta, Yellow, and Key (Black). This is the industry standard process colors used in full- color offset printing. The combination of these four colors can produce a wide array of colors.

Crop Marks

A thin pair of lines on each corner to show where the final cut will take place. Also called “Tic Marks”

Dots Per Inch (DPI)

Also referred to as Pixels Per Inch (PPI), which is a measurement of resolution of a printed image determined by the number of dots that fit into one inch. For optimal results, your image must be at least 300 DPI/PPI at the final output size. Please do not attempt to change a low resolution image to a higher one by changing the DPI/PPI in your image software. Doing so will result in a blurred output.

Grayscale

An image made up of a range of densities of black ink.

Grippers

The metal fingers on printing presses that hold the paper and controls it as it passes through the press or cutting machine.

Indicia

Postal information preprinted on a mailing envelope or a piece in place of a stamp.

Matte

Dull non-glossy finish.

Overprint

To print one image over a previously printed image, or have a digital file constructed in such a way that on object does not “knockout” of another. An example of overprint would be, printing type over a screen tint to avoid trapping issues.

Overrun

Production of larger quantities than ordered. Generally, we provide at least 5% overs, but reserve the right to be 10% under the ordered quantity.

Pantone Matching Systems (PMS)

The most popular color matching system used in the printing industry. A true PMS color is defined by a mixture of inks that will provide a specific color. PMS colors are often associated with a color code and can be used to produce colors outside the CMYK gamut.

Reverse

Type, graphic or illustration reproduced by printing ink around its outline, thus allowing the underlying color or paper to show through and form the image. The image ‘reverses out’ of the ink color. Also called knockout and liftout. In the case of process printing, this usually refers to white type on an colored background.

RGB, Red, Green, & Blue

These are most commonly used with television screens and computer monitors but are not used in offset printing. RGB files should be converted to CMYK. Colors may need to be adjusted after the conversion and may not appear correct on your monitor.

Resolution

The number of dots or pixels of an image. The higher concentration of dots or pixels per inch, the more detailed the image will be. We requires a DPI/PPI of 300 or above.

UV Coating

A protective coating applied to a printed piece for a super glossy finish which enhances colors and provides limited protection against UV and water damaged. UV Coating is applied to a printed sheet, then bonded and cured with ultraviolet light, as opposed to Aqueous (AQ); which is cured with heat and evaporation. UV Coating tends to have a much glossier appearance than AQ Coating.
