Print Packaging FeaturesColor iQCPrint Packaging Features GuideVersion 8.0 July 2012Color iQC and Color iControl QC include features to assist in print / packagingworkflows (for iQC print version, or when user settings have “Print Packaging Workflow”setting enabled). Many factors can influence the quality of a print job, and when acolor is off the corrective action is not always apparent. Print Job Templates coupledwith QC Sets bring together many important metrics, like dot gain, trapping, graybalance, and others, in to a common framework. QC Sets provide the press operatorwith the critical information needed to determine corrective actions and ensure asuccessful print run.The basic steps to implement a procedural workflow for monitoring and controlling aprint job are as follows:1.Create a new e-Job30 July 2012 Revision 1.0Page 1

Print Packaging Features2.Within the new e-Job template create a Print Job Template to define the QC Setworkflow (see below)3.Measure or import the required standards in to the e-Job template4.Appropriately name and save the e-Job templateOn initiating the print job workflow, the first step would be to create a new e-Job fromthe template created above:The new e-Job will open with the appropriate Print Job Template settings defined andincluding the required standards. The next step is to initiate measurements using a QCSet. Select the “Measure QCSet ” option from the Data Measure with Spectro menu item:The Read QC Sample Set dialog box will be displayed:30 July 2012 Revision 1.0Page 2

Print Packaging FeaturesAfter entry of the initial QC Set run information (Machine, QC Job, etc.), the software willprompt you sequentially for the required measurements as indicated by the blue arrow:30 July 2012 Revision 1.0Page 3

Print Packaging FeaturesThe system will continue to prompt for measurements until all of the requiredmeasurements, as defined in the Print Job Template, have been completed: The fieldsMachine, QC Job, and QC Set are mandatory and will persist from run to run.30 July 2012 Revision 1.0Page 4

Print Packaging FeaturesWhen all of the required measurements have been completed, the options to exit theRead QC Sample Set dialog box, Done , or read another QC Set, Next QCSet , willbe enabled:Selecting Done will save all of the measurements to the active e-Job. A new dataitem corresponding to the complete QC Set run will be added to the QC Tree View underthe QC Sets node.30 July 2012 Revision 1.0Page 5

Print Packaging FeaturesSelecting to run measure another QC Set will display the Read QC Sample Set dialogbox and automatically increment the QC Set number:.Subsequent runs of the QC Set will add new items to the QC Set node within the QCTree View.30 July 2012 Revision 1.0Page 6

Print Packaging FeaturesPrint Job TemplateThe parameters that determine the operation of the Read QC Set Sample procedure aredefined in the Print Job Template dialog box. The Print Job Template dialog box isaccessed from the main Settings dialog box.These settings are stored within an eJob or settings / template file (depending on youre-Job options) and define a workflow for the QCSet read procedure for measuring andcontrolling multi-color designs in the print / package industry.30 July 2012 Revision 1.0Page 7

Print Packaging FeaturesThese settings are stored within an eJob or settings / template file (depending on youre-Job options) and define a workflow for the QCSet read procedure for measuring andcontrolling multi-color designs in the print / package industry:Template NamePrint Job Templates can be stored as named objects(*.NGHdesign) files so that they can be used across multiplee-Jobs and templates.SubstrateThe substrate, or paper type, associated with print jobtemplate. Substrates are measured in to the system fromthe Date Measure with Spectro Measure Substrate menuoption.Commenttemplate.Test field for adding descriptive information about the designSolidsDrop down control to set the number of Solid colors used inthe design template. Available settings are Auto or 0 to 10.The Auto option will set the number of solids based on thetotal number of Standards identified as Solid and Processcolors in the associated e-Job. The maximum number is 10.Please note that Standards can be identified as a Solid orProcess color under the Name tab on the Standard Propertiesdialog box (shown below).30 July 2012 Revision 1.0Page 8

Print Packaging FeaturesDE ToleranceNumeric edit fields allowing you to enter DE pass / failtolerances for the Substrate, Process, and Spot Colors.Density ToleranceNumeric edit fields allowing you to enter density pass / failtolerances for the Process and Spot Colors.The next entry field will vary based on the particular workflow selected: Simple, PSO,G7, etc.dSpread Tol Tints30 July 2012 Revision 1.0Numeric edit fields to enter the tolerance for tonevalue increase between cyan, magenta, and yellow ina G7 workflow.Page 9

Print Packaging FeaturesdTVI Tol TintsNumeric edit fields to enter the tolerance for tonevalue increase in a PSO workflow.Dot Area Tol TintsNumeric edit fields to enter the dot area tolerancelimits in the General and Simple workflows.Process Color TintsGrouping of entries to define the number of Process Colors (0to 3) and their associated Tint percentages and Target DotArea values.Spot Color TintsGrouping of entries to define the number of Spot Colors (0 to3) and their associated Tint percentages and Target Dot Areavalues.OverPrintsGrouping of entries to define the number (0 to 3), targets,and tolerance for controlling OverPrints.OverPrints aredefined by the Standard and the two inks used.Gray BalanceGrouping of entries to define the number (0 to 3), targets,and tolerance for controlling Gray Balance. Gray Balance isdefined by the Standard, the tint percentage, and the threeinks used.Read QCSetsA QCSet Read dialog uses a Print Job Template (described above) to automatically stepthe user through measurement of a multi-colored print design (with solids, tints,process colors, spot colors, Overprints, and Gray balance patches), and reports on theQCSet as a complete quality control test.30 July 2012 Revision 1.0Page 10

Print Packaging FeaturesDesignThe name of the Print Job Template used within the QCSetprocedure.MachineMandatory edit field allowing you to enter a press number ordescription.QC JobMandatory edit field allowing you to enter the name for thisinstance of the QCSet. Subsequent runs of this QCSet willpersist this name.QC SetNumeric edit field to identify a print run. This value will beautomatically incremented in subsequent runs of this QCSet.QCSet CommentEdit field to allow information pertinent to the QCSet to beentered.The middle portion of the Read QCSet dialog will vary based on the number and type ofelements in the design: solids, tints, process colors, spot colors, Overprints, and Graybalance patches.10 Targets: 4 Solids, 3 OverPrints, and 3 Gray Balance30 July 2012 Revision 1.0Page 11

Print Packaging Features5 Targets:The lower portion of the Read QCSet dialog provides options to display a trend plot(showing the progression of information across multiple runs of the QCSet), a delta Labplot, or the tag information associated to each measurement.The up and down arrow controls allow you to cycle through the various color targetscontained with the QCSet.30 July 2012 Revision 1.0Page 12

Print Packaging FeaturesThe remaining controls within the Read QCSet dialog box include:The Done control becomes active on completion of theQCSet and closes the QC set view.The Next QCSet control becomes active after completionof a QCSet run to allow you to increment to the next instanceof this QCSet.Exports the contents of the QCSet to a CxF3 file. Please notethat this option is only available if a QC Set is re-opened,otherwise the CxF file is exported automatically.If a QCSet has been run multiple times, these controls allowyou to move between the different runs.Cancels and exits the Read QCSet dialog.QC Set ScoreThere is an additional field in the lower left corner of the Read QCSet dialog box. This isthe QCSet score.The “score” is a measure of the “goodness” of the QCSet. It is based on a ranking from0 (poor) to 100 (perfect). 50% of the score comes from the average DE of all of thesolids, 25% of the score comes from the percentage of the number of failed solids (canbe failed for DE or for density), and 25% of the score comes from the percentage offailed tints.30 July 2012 Revision 1.0Page 13
