DISC LABEL SPECIFICATIONS for CD Cards

 

A screen printing process for printing the label onto the CD surface. The following types of print can be processed:

1.      Line Prints with up to six different spot colours.

2.      Halftones and duotones.

3.      4 colour process print (picture disc) including a solid white background if required.

 

FILM SPECIFICATIONS

 

To produce screens for printing we require the disc label film to be supplied as RIGHT READING POSITIVES - EMULSION UP.

 

The CD label film must be supplied with a separate piece of film for each colour that you require printed.  The appropriate colour name must be marked clearly on the applicable piece of film.

 

Where a while base or a specific colour is required as a base coat for the CD, film must be supplied to ensure exact registration of label print.

 

A colour proof or a colour laser print must be supplied with the film.  This ensures correct colour matching and reduces the risk of errors.

 

REGISTRATION MARKS

 

To ensure correct registration of the print we have outlined below the registration marks that must be included on the film.  These must appear on every piece of film supplied.  The registration marks are shown in detail on the disc label templates.

 

A series of four dots need to be placed on the film work.  These are critical to the automatic register system and the print machine performance and must be adhered too.

 

A series of cross hair crosses is also to be placed on the film.

They will be used as a back up system to the dots.  The size of the cross hairs is not critical but the distance from the image is.

 

A 6mm long and 1mm wide registration mark is also to be placed on the film as shown in the DISC LABEL ART SPECIFICATION sheet.

 

 

 

 

HALFTONES AND DUOTONES:

 

Strict attention to detail is required when printing halftones or duotones, please ensure you abide by the specifications provided below. 

 

   Screen ruling:                                  133 lines per inch (Ipi)

   Type of dots:                                   Elliptic

4 COLOUR PROCESS DISC LABEL (PICTURE DISCS)

 

Four colour process (picture) disc labels use the CMYK colour combination.  This printing process may be more appropriate where a fine image is required and final results are critical.

 

It must be noted that the disc label surface is silver not white.  In the case where key features are required to be white (ie teeth or eyes on a face) a white base must be printed first.  Where a white base is required as a base coat for the CD, film must be supplied to ensure exact registration of label print.

The film specifications for printing a 4 colour process disc label are as follows:

Screen ruling:                                    133  or  150 line per inch

Screen angles:                                  Yellow             90

                                                            Cyan               75

                                                            Magenta         45

                                  Black     105

 

Type of dots:                                      Elliptic

 

Density Range:                                  Highlights       15%

                                                            Shadows        80%

 

Proof Type:                                       Chemical or Digital proof

 

 

We recommend your catalogue number be included in the CD label artwork to ensure correct identification.

 

Each piece of label film must be marked with the catalogue number and the corresponding PMS colour.  The identification must appear outside the image area and be a minimum of 12 points in bold type face.

 

 

COLOURS

 

The Pantone Matching System (PMS)is used as a standard colour system.  UV curable inks are used and  any coated PMS colour including metallics and fluorescents can be matched.

It should be noted that PMS colours printed directly onto the CD's metal surface con appear slightly different in colour than those printed onto paper.
