accreditation procedure | back to digital proofing

Procedure for Proof Vendors seeking accreditation by 3DAP

Vendors wishing to become 3DAP compliant must complete the following procedure:

  • Order the 3DAP compliance kit info@3DAP.com.au The kit includes:
    a)  3 x 3DAPv3 Accreditation Form pdf’s – one for each papertype
    b)  3 x visual reference target proofs  – one for each papertype
    c)  Tolerance documentation & measurement data for targets & control wedges
  • Produce digital proofs for Papertype-1, Papertype-3 and Papertype-4 Accreditation Forms that visually match the reference proofs supplied, and also fall within the proofing tolerance figures provided (see 3DAPv3 Tolerances for Proofing information).  The measurement data provided for Papertype-1 is derived from Fogra 39L data, the Papertype-3 is from Fogra 45L data and the Papertype-4 is from Fogra 47L data.

  • Create documentation for each proofing solution that indicates the following: VENDOR NAME, PROOFING DEVICE, RIP SOFTWARE, OUTPUT RESOLUTION, PROOFING STOCK, AND INK SET USED. This information should be supplied in the correct format for publication on the 3DAP website and should include vendor contact details.
  • Submit the digital proofs along with relevant documentation to 3DAP for accreditation. Papertype-1, Papertype-3 and Papertype-4 submissions will all need to meet the necessary criteria at the same submission to validate the proofing solution gaining accreditation.
  • The vendor will keep the target proofs used in the process. 3DAP will archive the approved digital proofs.
  • Approved vendors will be notified and then published on the 3DAP website and issued with a certified 3DAP V3 control strip for that particular accredited proofing solution.
  • At the end of each 12 month period from the original date of approval, the vendor is obligated to output and re-submit new Papertype-1, Papertype-3 and Papertype-4 proofs for re-accreditation, meeting the above mentioned criteria once again in order to keep their approved status current.
  •  The proof vendor agrees to not release the 3DAP control wedge for the 3 paper types to a customer (proof originator) until they are reasonably satisfied that:

    a)  The sample proof produced by the proof supplier matches the vendor master proof within the specified tolerances.
    b)  The proof supplier understands their responsibility to measure and maintain proof consistency within the specified tolerances.
    c)  The proof supplier uses the control strip aware of the fact it is their responsibility that the proof supplied with the control strip will be produced in accordance with procedure set out by the proof vendor and complies with the documented QC tolerance
    d) The proof supplier is aware that a 3DAP compliant proof must be proofed directly from the file supplied to the publisher/printer.
