About PSAsm

PSAsm (Printing Standard Audit) is an impartial, objective process developed to audit the ability of a printer to produce printed materials that conform to a recognized characterization dataset and to operate a standards-compliant workflow. GRACoL® and SWOP® can be selected by the printer as aims for conformity assessments. If the printer chooses GRACoL (SWOP) and passes the PSAsm Audit, the printer will be awarded “PSAsm Certification to CGATS TR006 (TR003, TR005) Dataset according to CGATS TR016”. If the printer is a G7 PC Master, IDEAlliance will award the printer an additional certification, “G7 GRACoL (SWOP) Certified”. By attaining PSAsm Certification, printers demonstrate that they have mastered the use of standards in their workflows.

PSAsm Audit and Scoring

PSAsm auditor completes one-day on-site audit. The applied company must submit the press form to RIT for measurement. RIT will evaluate based on the following aspects.

  • Data reception:
    Evaluate the TAC (Total Area Coverage Management) and color management / color conversation.

  • Requirements on proofing:
    It is based on ISO 12647-7, including substrate color, deviation tolerance of CMYK solids (i.e. maximum difference from aim values) and within-sheet variation, TVI (Tone Value Increase), neutral gray, IT8.7/4 and IDEAlliance color control strip.

  • Prepress & CTP assessment:
    It includes prepress and platemaking process, plate quality control, plate handling & maintenance, RIP settings, etc.

  • Print conformity assessment:
    It evaluates from various aspects, including deviation tolerance (i.e. maximum difference between OK sheet and aim values, evaluate IT8.7/4, CMYK solids, 50% CMYK and neutral gray); variation tolerance (i.e. maximum difference between press sheet and OK print, evaluate CMYK solids, 50% CMYK and neutral gray); within-sheet variation (IT8.7/4). Main focus on PSAsm is to use ISO 2846-1 compliant ink and to use either one calibration method stated in ISO TS10128 (Tone Value Increase, Gray Balance or Device-link color management). Substrate-correction can be applied based on GRACoL or SWOP aims.

  • Print conformity assessment is calculated according to deviation tolerance, variation tolerance and within-sheet variation. Different weighting factors are set for each aspect. The results of the three aspects will be shown in different level (Level A, B, C) and the total score will combine the three results.
