1. 1. Color halftoning methods for screen printing and special effect pigments : Reproducing iridescent colors

   University essay from Linköpings universitet/Institutionen för teknik och naturvetenskap

   Author : Alfred Rundquist; [2023]
   Keywords : iridescence; color; halftoning; screen; printing; ink; special; effect; pigments; media technology; simulation; iriserande; färg; rastrering; metod; screentryck; silkscreentryck; raster; färgreproduktion; simulering;

   Abstract : Iridescence is the property that makes colors vary by angle of observation. Technology has made it possible to print with ink that has this anisotropic property. The ink that is used contains microparticles and therefore only specific printing methods can be used, for example screen printing. READ MORE

3. 2. Quality Assessment for Halftone Images

   University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

   Author : Johnny Elmèr; [2023]
   Keywords : Image Quality; Halftoning; Subjective Image Quality Assessment; Subjective Testing; Objective Image Quality Metrics;

   Abstract : Halftones are reproductions of images created through the process of halftoning. The goal of halftones is to create a replica of an image which, at a distance, looks nearly identical to the original. Several different methods for producing these halftones are available, three of which are error diffusion, DBS and IMCDP. READ MORE

4. 3. Hybrid Color Halftoning

   University essay from Institutionen för teknik och naturvetenskap

   Author : Ahmed Tausif Aijazi; [2010]
   Keywords : Halftoning; Color; Hybrid; Flexography; Printing; image reproduction;

   Abstract : Halftoning methods can be divided into two main categories, namely AM (Amplitude Modulated) and FM (Frequency Modulated). Some printing methods, such as Flexography, are not able to produce dots small enough to handle the highlights and the shadows of the original image by just using AM halftoning method. READ MORE

5. 4. Inverse Halftoning Using Inverse Methods

   University essay from Institutionen för teknik och naturvetenskap; Tekniska högskolan

   Author : Oscar Gustavsson; [2007]
   Keywords : ;

   Abstract : This Master´s thesis discusses the problems concerning inverse halftoning, which means converting a halftone image into a continuous tone one. The thesis evaluates the use of inverse methods, showing promising results. The algorithm is implemented and tested using Matlab and serves as a prototype for possible full scale applications.

6. 5. A study of FujiFilm’s FM screening method TAFFETA

   University essay from Institutionen för teknik och naturvetenskap; Tekniska högskolan

   Author : Tobias Johansson; Linda Karlsson; [2006]
   Keywords : ;

   Abstract : The study of Fujifilm´s halftoning method Taffeta has been done on behalf of Fujifilm Sverige AB, they especially wanted a subjective evaluation of Taffeta. Taffeta is a FM halftoning method of second generation, specific for this halftoning method is the structure of the dots, which should give a print with more evenness. READ MORE
