  15. 15. Printing Quality Management To get ISO 12647/3 Check printing defects Report consumabels
  16. 16. A ) ISO 12647/3 :2005
  17. 17. Dep. Property Set values Electronic data delivery PDF/X-1 or PDF/X-3 Press profile ISO 12647-3 (IFRA 26) C T P Ink saving GCR Ton value sum Max 240-260, Black >%85 Rips Ton values 500 lpcm Screen frequency 40 L/ cm FM screen 40 micron Screen angle CMYK 15,75,0,135 Dot shape elliptical dot, link-ups %40,%60 Purchasing Newsprint La*b* 82,0,3 ( tolerances: 3,1,1 ) Adver. , Design, Prepress, Page Delivery
  18. 18. A ) ISO 12647/3 :2005
  19. 19. A ) ISO 12647/3 • ISO color coordinates • TVI dot gain curve So;
  20. 20. A ) ISO 12647/3 … and technology develops • ISO color coordinates means decrease the ink density ISO Lab (IFRA 26) measuring mod : ISO-Check
  21. 21. A ) ISO 12647/3 • ISO color coordinates * With black backing ISO (IFRA 26) values Red 52 41 25 Yellow 78 -3 58 Green 53 -34 17 Cyan 57 -23 -27 Blue 41 7 -22 Magenta 54 44 -2 Paper 82 0 3 Black 36 1 4 only Paper and CMYK is used M C Y g r b K
  22. 22. A ) ISO 12647/3 • ISO color coordinates Only yellow b* value changed BUT ; not practical Our referance values ? Why not? First : determine perfect dots in ISO Second: measure Lab with no b.backing
  23. 23. A ) ISO 12647/3 • ISO color coordinates You can put your new referance values ColorScale mod for new ref. values ISO-Chek mod ISO Lab values has already loaded
  24. 24. A ) ISO 12647/3 • Dotgain
  25. 25. A ) ISO 12647/3 • Dotgain old ….. 4,5 mm new ….. 3 mm
  26. 26. A ) ISO 12647/3 Change the apparatus with a smaller one and make tests
  27. 27. A ) ISO 12647/3 • Dotgain %100 %40
  28. 28. A ) ISO 12647/3 • Dotgain %40
  29. 29. 0,78 66,8 0,81 69,5 0,82 67,8 1,14 63,6 density % dot gain • Dotgain A ) ISO 12647/3 *Recordings are done by automatic measurement mode
  30. 30. While the Q. Engineer measures and records the dots to ERPVideo-1 : Picture .
  31. 31. Daily Printing Quality Report Ref. densities difference Operator succes DG Production Name
  32. 32. WEEKLY P. OPERATOR DENSITY SUCCES REPORT
  33. 33. Averages DG average The values to be applied to CTP rips
  34. 34. /25 36 For consistence Printing DG, plate controls is obligatory Every week produce a test plate which has a “plate scale” job on it. Plate Scale
  35. 35. Measurements are done and recorded by a plate measurement device. Then the program calculates the dot gain of the plate
  36. 36. /25 38 Plate Quality Report
  37. 37. %2, %98 and % 50 tone values are measured with plate densitometer by the prepress man to understand if there is an abnormality or not. If the values are seem to be changed, he produce a test plate for exact measurement and calibration Daily Plate Checking A tone scale stays on the bended side of the plates is checked daily. Plate is taken before P&B machine for measurement. only Plate Plate + Press Applied dot gains
  38. 38. While the Q. Engineer evaluates and records the print defects to ERPVideo-2 : B Printing Defects Checking
  39. 39. Printing Quality Report Solve mains Notice news Main target:
  40. 40. DEFECTS INCQC points PAGES B Printing Defects Checking

  42. 42. So ; we are checking ourselves like we are in competition INCQC everyday B Printing Defects Checking
  43. 43. First run or restart - following a stop copies: Customers complains mostly : from the “startup “ newspapers or “restart - following a stop ” newspapers. Because mechanically they are the worst. salable , low quality, not salable, B Printing Defects Checking
  44. 44. C Consumabels Reporting a) are being used (Current) Ex: Newsprint Evaluation Report b) Test metarials Target is; To prepare a list to our purchasing department. Show preferred and not preferred So we ask: not to bought unwanted, instead, the preferred if possible much

  49. 49. Described by our personals; criterions , weights 4 different working areas Ex: Ex: Register and tension control Cleaning Reel Stand Ink and water adjustments
  50. 50. Ex: 45gr. Std Newsprint Newsprints from top to bottom they are in 3 groups GOOD, BAD, WORSE GOOD BAD
  51. 51. Printing Quality Management Try to get ISO Newspaper standart check printing defects Report newsprint AS a SUMMARY
