Quality Audit- Why and How The Brazilian newspaper market was facing a big challenge concerning to printing quality and readers demandings. Our newspaper has change its layout to accomplish those market changes and be more competitive with the other information technologies as the internet, palms and more. As a consequence, the printing quality, productivity and waste reduction became the most relevant issues in the Industrial area. Therefore we decided to hire Goss Quality Auditservices to help us achieving these objectives. O Estado de S. Paulo and Goss teamed up to conduct the Quality Auditto improve print quality, productivity and reduce waste. Our efforts started with a lengthy team meeting to understand issues and identify objectives. The following is the summary:
Quality Audit- Why and How • 1. Optimum ink/water balance was needed and was regarded as priority one. The goal was that the operators didn’t adjust ink, at all, during make-ready. This required the following sub-categories: • a. Modifying the control parameters; • b. Investigating presets; • c. Spray-bars evaluation; • d. Dampening solution pumping system; • e. Ink pumping system; • f . The Newsliner’s ink train settings; • g. The Newsliner’s dampening train settings; • h. Consumable. • 2. Registration optimization: • a. Side-lay; • b. Circumferential. • 3. Waste savings reduction: • a. Operational methodology. • 4. The human factor: • a. Press and Prepress.
Audit Group To accomplish the Quality Audit program we have created a multi-disciplinary group, formed by professionals from Maintenance, Engineering, Pressroom and Prepress areas. From left to right: Marcal Santos Barbosa – Pressman Trainer; ValterCraveiro dos Santos – Prepress Support; Edson Silva Lima – Mechanical Maintenance Supervisor; Roberto Dias da Costa – Process Supervisor; Jamir Correa Pupo – Pressroom Supervisor; Rinaldo Francisco da Silva – Prepress Support; Vitor Nicolau Teixeira – Electrical Maintenance Supervisor; Edson Lino dos Santos – Engineering Supervisor.
Group Methodology - Multi-disciplinaryGroup; - Gosscoordination; - Six Sigma oriented.
Wehavecreatedanspreadsheetwith over 90 actionscoveredduringandaftertheQualityAuditprogram. It wasdividedintoPrepress, Pressroom, Engineeringand Management categories . Quality Group Spreadsheet
Actions Toward Quality • Engineering (8 actions) • DampeningCurve • Inking Curve • Blanket • Fountain Solution • Management (5 actions) • OPB • RIP • Six Sigma • Pressman Training • MechanicalAudit • Pressroom (72 actions) • Dampening System • Inking System • Meridian • Operation Prepress (8 actions) • Rip Interface • PAR • TestForm • Color Management
Actions Toward Quality Prepress – Some actionsexamples: • Rip Interface • Possibilityoflinkingthe RIP to theNewsliner. • PAR • AdjustedtheMeridianpresets; • Overall maintenance; • Correctedfilmpattern. • TestForm • Created a newtestform to checkinkandregistration.
BasedontheQualityprogramwehavecreatedthisnewtestform to set upourNewslinerPresses. It hasSolidbarswith 75 and 40% ofcoverage in eachcolorandalsoregistrationmarks. Goss TestForm
Actions Toward Quality Pressroom – Some actionsexamples: • Spray bar NozzleTip, Plunger, chamberandValvebody • Modelstandardization: • Wehavefound some nozzletipswiththewrongmodel in stock as well some plungerswithdifferent rubber materialandbodyvalveswithdifferento’ringchanneldimensions. • Chemicalcompatibilitytest; • Maintenanceprocedures; • Receivinginspectionandanalisys; • Testerdevelopment .
Flow Metering Device Thistesterdevicewascreated to analise thenozzletipflowandtheplunger performance prior to enter in our stock andduring regular maintenance. It performes a predeterminedflow test. Basedonthe volume variance (± 3%) thenozzletipandplunger is acceptedorrejected.
Digital Microscopy Dampeninguniformity is critical to wastesavings. Wecreated a procedure to evaluatethenozzletips, chambersandplungersthrough digital microscopybeforeit entersour stock andduring regular maintenance.

Actions Toward Quality Pressroom – Some actionsexamples: • Dampening System • Spray bar Testerdevice; • Changeofthedampening solution unitregulator; • Modify Spray bar to reflecttheactual web width (54” to 50”); • Adjustthewaterformroller to notslip.
Spray Bar Tester Based on the Quality program information we have built this spraybar tester in order to balance and equalize the nozzle spray.
Dampening Fluid Regulator As a recommendationfromtheGossauditprogram, wehavechangedtheDampeningfluidregulator. Thenewregulator in use is fromTechnotrans. Withthepreviousregulatorwecouldnotget a uniformdampeningpressure. Thepressurevariation range was ± 20 psiduringthepressrunning. Withthenewmodelthepressurevariation range is ± 5 psi, resulting in a more uniformdampeningflowduringtherun.
Actions Toward Quality Pressroom – Some actionsexamples: • Inking System • DrySolidInktestonunits; • Overall maintenanceon digital pagepackandfountainroller; • EqualizationofInkpressureline (30 to 40 psi).
Actions Toward Quality Pressroom – Some actionsexamples: • InkandWater curves optimization; • Inkanddampeninguniformity.
Actions Toward Quality Pressroom – Some actionsexamples: • RegisterpinOptimization: • We are still workingontheregisterpinoptimization. Wehavedone some measurementswiththetestformandcreated some statisticalgraphs, showingthedeviation to becorrected.
Actions Toward Quality Engineering – Some actionsexamples: • Discussed the science and technology of emulsion behavior, and the interaction between ink, dampening solution, plate design and the press roller train; • Plateroomtemperatureandhumiditycontrol; • PressParametersreview: • ColdAutofloodDuration; • WarmAutofloodDuration; • Warm Start AutofloodDuration; • InkFormOnDelay.
Actions Toward Quality Management – Some actionsexamples: • Mr. Ragy Isaac provided two and half hours Six Sigma overview; • Studyof a CTP viability for thePrepressarea.
Results After this period the Audit Group was able to achieve the following objectives:
Results Newsliner 2008 Average – 860 copies Newsliner 2009 Average – 690 copies • Reduced start-up waste:
Results - Web breaks reduction: 2008 Web Break Rate - 4,17% 2009 Web Break Rate – 3,51% 2008/2009 comparison: On start-up – 64% During the run – 32% During the paste cycle – 21% On press stop – 53%
Results • Established new Ink Curves:
Results • Established new Dampening Curves:
Results • Produced drier printed product with a stable ink and water balance; • Trained all press crews on the use of Percent Mode to set density if required; • Provided details of the spray-bars technology’s pitfalls and how to avoid it. The discussion included the theory of operations of a spray-bar, controls required; • Identified the proper dampening solution pressure at the Newsliner’s unit regulator (60 psi); • Identified, and corrected, the PAR as the major cause for inking unpredictability.; • Improved the overall print quality.
Future Plan - Lean Six Sigma implementation; - CTP and OPB for Goss Press; - Goss Pressman training; - Goss Mechanical Audit; - Newsliner/Headliner controls upgrade.
