24 A ) ISO 12647/3 Dot gain and grey balance values are informative only So the most critical parts of IFRA26; ISO color coordinates ( La*b* values ) TVI dot gain curve 24

25 A ) ISO 12647/3 ISO color coordinates density ISO Lab (IFRA 26) measuring mod : ISO-Check means decrease the ink

26 A ) ISO 12647/3 ISO color coordinates

27 only Paper and CMYK used A ) ISO 12647/3 ISO color coordinates ISO color coordinates * With black backing g C Y K b r M ISO (IFRA 26) values Red Yellow Green Cyan Blue Magenta Paper Black

28 A ) ISO 12647/3 ISO color coordinates While using ISO Lab measurement mode there is a difficulty Always black backing should be used, but it isn t practical. So what? There can be any way to use it without black backing? 28

29 A ) ISO 12647/3 ISO color coordinates First : determine perfect dots in IFRA26 Second: measure Lab with no black backing and look at the differences Only yellow b* value changed

30 A ) ISO 12647/3 ISO color coordinates ISO color coordinates You can put your new referance values ISO-Chek mod ISO Lab values has already loaded ColorScale mod for new ref. values

31 A ) ISO 12647/3 Dot gain Dot gain The most tone value increase is between % area

32 A ) ISO 12647/3 Dot gain old.. new.. 4,5 mm 3 mm

33 A ) ISO 12647/3 Dot gain Change the apparatus with a smaller one and make tests

41 The most tone value increase value of each color is stored in RIP for compensation

42 For consistency in Printing quality Plate related quality control jobs are also crucial in daily production weekly, monthly, & when necessary Check and control Calibrate 42

43 Daily Plate Checking Applied dot gains Plate + Press only Plate Plate is taken before P&B machine for measurement. Only %2, %98 and % 50 tone values are measured

44 Weekly Plate Calibration Every week a test plate which has a plate scale job on. produced Plate Scale /25 44

45 tone value increase values of each color are stored in RIP for compensation
