  1. For a standard CD-R / DVD-R (Duplication or Replication) a pdf 125mm x 125mm square (CD/DVD print) – this allows for some bleed.
  2. Artwork to be designed with the circles in so that you, the client, knows what is going to be cut out and then to save it without the outer and inner circles.
  3. Convert text without fail to curves / outlines or paths – otherwise you will lose fonts or have corrupt fonts.
  4. The artwork must be saved at 300dpi
  5. Text on the discs should be no less than 6 points (6 points could lead to bleed out), but preferred size is 8 points.
  6. Please supply disc artwork in CMYK or Pantones
  7. If artwork is pantones, please supply the pantone reference numbers.
  8. Please supply inserts (Booklets, Back Inserts, Sleeves, etc.) in CMYK
  9. If the above process is not followed, then we will have to send the artwork back for correction.
  10. The same will apply for the artwork for the booklets, inlays and DVD sleeves.
  11. Where we are designing the artwork please also follow this process.
  12. A minimum charge of R350 per hour will be charged if we will be doing the design.
  13. Please always supply artwork with a minimum of 5mm bleed all around.

How To Manufacture CD’s/DVD’s Chitchat2019-03-11T06:41:43+00:00
  • A CD is manufactured every 3.5 seconds
  • A DVD5 is manufactured every 6,5 seconds
  • Lacquer – this is used to protect the aluminum coating and it allows us to screen print the disc art onto the disk
  • Polycarbonate must be uncontaminated otherwise the moulding machine will run at inefficient yields
Which File Formats Are Best For Discs2019-03-11T06:43:28+00:00
  1. CD Audio – this disc format conforms to Philips Red Book specification and requires authoring. This disc shall play in both modern-day players and an “old school” CD Player. The spec calls for a maximum of 75 Minutes total play time, however the disc can hold up-to less than 80 minutes. Naturally any master supplied that holds greater than 75 Minutes, JDM will not guarantee 100% playability of the replicated/duplicated disc.
  2. CD ROM – a data disc that can comprise of a multitude of file formats, i.e. mp3s, waves, mp4s, PDFs, etc. This disc format holds a maximum of 800 MBs of data. If media files are contained on this disc format it will not play in an “old school” CD Player, it will only play in a modern media player – if the player supports the media file format.
  3. DVD Video – this disc format conforms to ISO DVD Video specification and requires authoring. This disc will play in both modern media players and “old school” DVD Video Players.
  4. DVD ROM – a data disc format that can comprise of a multitude of file formats i.e. mp3s, waves, mp4s, PDFs, etc. Depending on the disc type the maximum data; DVD5 – 4.3 GBs, DVD9 – 8.7 GBs, DVD10 – 9.2 GBs. Any media files that are contained on this disc it will not play in an “old school” DVD Video Player, it will play in a modern media player – if the player supports the media file format.
Different Types of Discs2019-03-11T06:44:00+00:00
  1. CD – a single layer disc.
  2. DVD5 – a dual layer disc with Layer 0 as the data layer and Layer 1 as the dummy layer.
  3. DVD9 – a dual layer disc with both layers holding the data, the player switches to the second layer to continue playback.
  4. DVD10 – a dual layer disc with both layers holding the data, this disc must be flipped around to continue playback of the second layer (much like an LP record). This option is no longer manufactured
