Introduction

3DAP (Digital Data Delivery for Australian Publications) is an industry group committee that was formed to address the needs of a totally digital production environment for the magazine publishing industry, in particular, the workflow required for computer-to-plate.

These guidelines are expected to be phased in over a period of time and it is therefore important to contact the magazine publisher to confirm that they wish to receive digital files and that they are able to accept PDF files in their current workflow.

Announcing 3DAPv2 Guidelines

Based on feedback from the industry, and extensive use of 3DAP Guidelines for delivery, the Committee has revisised the guidelines for the file format to 3DAPv2.

A summary of the changes are:

• Enforce use of 32 bit CMYK, not indexed CMYK images.
• Increase Monochrome Images to 2400dpi.
• Removing Transfer Functions.
• Removal of OPI comments.
• Remove any UCR/BG information.

We have provided a detailed description of these changes.

Improved Digital Proofing Documentation

The current list of Approved Digital Proofing Systems has reached 11. To improve the process, the 3DAP Committee has detailed the procedures used to approve Digital Proofing Systems.

The Committee

The focus of this committee has been to ensure that advertising material prepared by different sources for use in publication printing can be faithfully reproduced together on the same press sheet. It is also important for the same material inserted in multiple publications to be consistent. In order to achieve this, the major magazine publishers and printers in Australia previously endorsed a specification published as "The Guide to Publication Production for Heat-set Web Offset Printing ".This is based on the supply of final film separations and a chemical or machine proof produced from those films. The 3DAP committee has released guidelines to assist all parties supplying advertising as digital files and proofs to their publishers and printers.

The 3DAP guideline for the creation of digital files for advertising is based on the Adobe Portable Document Format (PDF.) For clarity, the PDF file that is generated in accordance with these guidelines is called a 3DAPv2 PDF file.

The 3DAP committee will continue to review file standards and digital proofing into the future and we welcome feedback from others in the industry regarding these guidelines. Feedback can be sent via email to info@3dap.com.au
