Sometimes the technical jargon of printing can be confusing. Here's a quick primer of common terms you might find in our website.
Glossary of Terms:
FTP - File Transfer Protocol - A commonly used means to transfer large files over the internet.
DPI - Dots Per Inch - A measure of resolution by the number of pixels per inch. Also know as PPI (pixels per inch).
PPI - Pixels Per Inch - A measure of resolution by the number of pixels per inch. Also know as DPI (dots per inch).
CMYK - Cyan/Magenta/Yellow/Black - The color method used for print media.
RGB - Red/Green/Blue - The color method used for monitor screens and lcd displays.
4/0 - An abbreviation that states a print product is one-sided full color: The four colors of CMYK are on one side (4) and there are no colors on the back side (0).
4/1 - An abbreviation that states a print product is full color with the four colors of CMYK on one side (4) and one color on the other side, usually black (1).
4/4 - An abbreviation that states a print product is double-sided full color: The four colors of CMYK are on both sides (4/4).
AI - Adobe Illustrator - Adobe Illustrator's native file extension.
PSD - Photoshop Document - Adobe Photoshop's native file extension.
JPG or JPEG - Joint Photographers Expert Group - Developed for compressing and decompressing digitized photos. Use this file type for photographic imagery intended for the Internet. It supports 24 bits of color information, and is most commonly used for photographs and similar continuous-tone bitmap images. Most imaging applications and plug-ins let you determine the amount of compression used when saving a graphic in the JPEG format. Unlike GIF, JPEG does not support transparency. If used for offset printing, make sure resolution is at least 300dpi and compression quality was set to high.
EPS - Encapsulated Postscript - EPS or vector graphics are resolution independent, meaning that you can enlarge them any number of times without having their resolution deteriorate. Vector images give you crisp, clean lines at any size. They don't, however, look as nice on screen as bitmap graphics do. If you have an illustration program like Adobe Illustrator, Macromedia Freehand or Corel Draw you can import and edit the images. Regardless of how they look on screen, EPS images print beautifully to a Postscript printer. The EPS file format can be used on a variety of platforms, including Macintosh and Windows. When you place an EPS image into a document, you can scale it up or down without information loss. Use this file type for vector graphics from drawing programs and multi-channel images from Photoshop such as duotones and clipping paths. EPS files can be graphics or images of whole pages that include text, font, graphic, and page layout information. This format contains PostScript information and should be used when printing to a PostScript output device.
TIF or TIFF - Tagged Image File Format - TIF or raster graphics are bitmapped graphics. Raster images are best used for images such as photographs or paint style graphics. They are versatile and can be imported into most software but their biggest disadvantage is that they are resolution dependent. Bitmapped graphics can be reduced in size successfully but if you try to enlarge them you will be subject to serious deterioration. TIF files can be black-and-white, grayscale, or color bitmapped-images, particularly those produced by scanners. This format generally does not compress the size of the image file significantly unless the image is scanned in line art mode. TIF files have better resolution and are good for outputs such as RGB and CMYK. The TIF format is the most common file format considered a “safe” format that is very stable, widely supported, cross-platform and rarely causes problems during output. Use this file type for scanned images or photos intended for offset printing
