Glossary

Disc of 80mm - known as the Single Compact Disc Audio (CD-S). On the 80 mm can be stored an amount of about 192 MB of data in digital format or 22 - minutes of audio recording.

Aspect Ratio - represents the report between the width and height of the image. A report of 4:3 means that the horizontal is a quarter higher than the vertical. The standard report in television is: 4:3 (1.33:1). The Report Widescreen DVD and HDTV is 16:9 (1.78:1).

Bleed or cutting edge - means that the printed image extends beyond the cutting line of the paper. The cutting edge appears at the top, bottom, left, and/or right of a paper.

Booklet - represents the brochure attached to each CD or DVD. Regarding the CD case, it is fixed in front and in the case of the DVDs it’s attached with the help of some interior clamps.

CMYK - Abbreviation for Cyan, Magenta, Yellow, and Black – Key Color, the four basic colors combined in various proportions, generate the full spectrum of colors for an image.

Compression - Compression is the process of reducing data storage. The compression rate affects the quality of images/information.

Dolby Digital - is the compression technology developed by Dolby Laboratories for sending information on six discrete channels. Offering multi channel digital sound, Dolby Digital can supply excellent surround sound. Known as a 5.1 system, the channels are front-left, front-right, center, back-left, back-right and the subwoofer channel for low frequencies.

DPI - provides a measure of the quality of scanned images or of the print resolution of a printer. The image quality increases along with the growth resolution, implying however, increasing the size of the files, for storing information. The recommended resolution for printing is at least 300 dpi.

DTS (Digital Theatre Systems) - the DTS audio format is another compression format, similar with Dolby Digital, developed by Dolby Digital. It is also a 5.1 system that uses a lower compression ratio.

Disc Duplication - is the process through which we realize copies 1 to 1 on recording disc devices by burning with laser.

DVD-5 - DVD (Digital Versatile Disc) - optical storage medium, single-layered DVD capable of holding 4.7 GB of data.

DVD-9 - is a dual layer version that can store up to 8.5 GB of data.

DVD-10 - can hold a volume of information up to 9.4 GB of data.

Master - initial support on which the client sends the information in final format for replication.

The Mastering - from technical point of view, it represents the final step made before the replication of a video material, after the final mixing ended.

The Mold - physical support of nickel with the size of 300 micron used for optical media duplication and which contains the disk image that will soon be produced.

MP3 - audio compression format of the information. The conversion in MP3 format does not affect the sound quality, though it achieves a 12 to 1 compression.

MPEG-1 - compression method used for the storage of audio and video information on the Video CD.

MPEG-2 - compression method used to store the information's on the Video DVD.

CD Replication - is the technological process by which are manufactured optical discs in large series, on specialized industrial machines, with the help of the mold, by injection and hot pressing.

PDF - document in digital format created by Adobe Acrobat program.

Polycarbonate - is the basic, gross material, from which the optical discs are made.

Premastering - is the first phase of producing a CD/DVD, a process that involves the encoding of audio tracks and the creation of a logical structure, of the information on the disk.

Print verso - is the print sided process on the back of a printed sheet.

Raster points - printing defect where printed points are higher than normal and causes darker color.

Sign of cutting - Marked lines on the border of the document that indicates the limit cutting, perforation, or paper bending.

Color separation - is the process by which a particular color shade is separated from the combination of the four colors for the printing process.

Digital printing - is the process by which an image coming from a digital file is printed directly on the surface of the paper of the CDs/DVDs without the need of a film or the mold. It represents the suitable printing method for small quantities or personalized prints.

Offset printing - is the print technology by which the color/ink is applied on the disc surface by using cylinders instead of direct print.

Reordering - represents any further replication of a title for which it already exists an order and the stamper (as long as the initial information remains unchanged).
