The CD Replication and Duplication fields use their own unique lingo. If you are feeling confused use this list with the links at left. to bring you up to date. For further questions please do not hesitate to contact us.
First order terms
do apply: Cheque with order.
Bit Map: In typographic imaging, the electronic representation of a page, indicating the position of every possible spot. (zero or one)
Bleed: Bleed: An extra amount of printed image which extends beyond the trim edge of the sheet per page.
Booklet: This is the cover of your CD package inside a jewel case or a wallet and can contain note, lyrics etc. CD books are bound together. Booklets are comprised of panels in multiples of four. So CD booklets are 8-panels, 12-panels or 16-panels. A four panel booklet is actually a folder as it does not need binding, it would simply be folded in half and slipped into the front of a jewel case.
Brochure: A pamphlet bound in booklet form.
Burn: In plate making, a common term used for a plate exposure.
CD Label: The text or image that gets printed onto the actual CD. This is screen printed.
CD-R: This is compact disc "recordable" or recordable CD. This is widely used in both professional, semi-pro and hobby studios for archiving and transfer of audio data. The laser writes the data onto the CD.
CD-ROM: This is a compact disc which has read only memory. CD Replication is the manufacturing process that replicates or "clones" your original master. A glass master is then created from the original master. From the glass master a set of stampers are made. Stampers are mounted into a high-tech injection mold machine. In the molding process a mold is created in a form of plastic disc. The disc is coated in a thin layer of aluminum. A protective lacquer is applied onto he disc and then hardened by ultraviolet (UV) light.
CMYK: Cyan, Magenta, Yellow, Black, subtractive primary colours
Colour proofs: Proofs made by photomechanical or digital means in less time and at lower costs than press proofs.
Cromalin: Off-press colour proofs using DuPont Cromalin materials.
One of the subtractive
primaries the hue of which is used for one of the 4 colour process inks. It
reflects or transmits blue and green light and absorbs red light.
Density: The degree of darkness of a photographic image.
Digital Colour Proof: An off-press colour proof produced from digital data without the need for separation of films.
Dot: The individual element of a halftone.
Elliptical Dot: In halftone photography, elongated dots which give improved graduation of tones particularly in the middle tones and vignettes - also called chain dots.
Glass Master: This is a plate, approximately 10" in diameter, coated with a photo-sensitive material. The digital data from the premaster disc is transferred to a computer at the replication plant and converted to a special coding format for CD manufacturing. After further processing the glass master is then used to ncreate a subsequent set of discs called the "father" "mother" and "children." The children can be called the "stamper" which is used to manufacture large numbers of discs.
Hard Copy: The permanent visual record of the output of a computer or printer.
Jewel Case: This is a plastic case that holds your CD, your Booklet and inlays.
Lacquer: A clear resin/solvent coating, usually glossy, applied to a printed sheet for protection.
Magenta: One of the subtractive primaries the hue of which is used for one of the 4 colour process inks. It reflects or transmits blue and red light and absorbs green light.
Matt Finish: Dull paper finish without gloss or luster.
Moiré: In colour process printing, the undesirable screen pattern caused by incorrect screen angles of overprinting halftones.
Process Colours: In printing, the subtractive primaries: yellow, magenta and cyan, plus black in four-colour process printing.
RGB: Red, Green, Blue - additive primary colours
Screen Angles: In colour reproduction, angles at which the halftone screens are placed with relation to one another, to avoid undesirable moiré patterns. A set of angles often used are: black 45, magenta 75, yellow 90, cyan 105.
Screen Printed: In photography, a print with a halftone screen made from a halftone negative or by diffusion transfer.
Varnish: A thin, protective coating applied to a printed sheet or CD for protection or appearance. Also, in inkmaking, it can be all or part of the ink vehicle.
Yellow: One of the subtractive primaries the hue of which is used for one of the 4-colour process inks. It reflects red and green light and absorbs blue light.
