    • Printing  standardization  trial   for  high-‐‑‒definition  printing  method   utilizing  Staccato-‐‑‒10  micron  dots 1 Dr.  SHIMIZU,  Hirokazu Vice-‐‑‒President,  WILL-‐‑‒POWER  CONSULTING  INC. President,  SHIMIZU  PRINTING  INC. Visiting  Senior  Researcher,  Waseda  University  Environmental  Research  Institute Expert,  ISO  TC130  (Graphic  technology)  WG11(Environmental  impact  of  graphic  technology)  
    • Agenda 1.Purpose  of  printing  analysis 2.High-‐‑‒definition  printing  method 3.Kodakʼ’s  printing  analyzer  “ColorFlow” 4.Analysis  of  printing  condition  in  practice 5.Summary 2
    • 1.  Purpose  of  printing  analysis 3 ✦Installation  of  “ColorFlow”  (Kodak)  for  analysis 1.  Color-‐‑‒matching  for  Japan  Color  Standard   •Ultimate  goal  is  adaption  for  Japan  Color  which  is   compatible  with  ISO12647 2.Color-‐‑‒matching  for  Direct  Digital  Color  Proof •Create  color  profile  for  DDCP  to  be  checked  as  first   proof  to  avoid  printing  proof  by  press   3.Color-‐‑‒matching  for  different  presses •Secondary  goal  is  perfect  alignment  of  presses  in  our   factory  and  other  partner  factories
    • 2.High-‐‑‒definition  printing  method 4 ✦Advanced  screening  tech.  for  high-‐‑‒end  printing Staccato  screening  (high-‐‑‒definition) Kodak  Staccato  is  advanced,  second-‐‑‒order  FM  screening  technology.   Staccato  screening  produces  high-‐‑‒fidelity,  continuous  tone  images  that   exhibit  fine  detail  and  an  extended  color  gamut,  creating  a   photographic  experience  free  of  visible  printing  artifacts,  such  as   subject  moire  and  rosettes. (Reference:  http://graphics.kodak.co.jp/KodakGCG/uploadedFiles/ Products/Color_̲and_̲Screening/Staccato_̲Screening/Staccato %20Brochure%20ENG.pdf) The  angle  and  frequency  of  half  tone  dots  in  conventional  AM  screens   can  cause  subject  moire,  screening  moire  and  unstable  rosette   structures.  Additionally,  fewer  and  larger  minimum  dot  sizes  in   highlights  and  shadows  in  AM  screens  can  result  in  loss  of  detail  and   increase  in  graininess.
