• The aim of this experiment is to create image data capable of being offset printed on paper through combining xylographic techniques with the image processing features available in Adobe Photoshop. Offset printing of xylographic images normally involves performing four-color separation by scanning a single complete work on a scanner. In this experiment, however, I printed the images of the different xylographic blocks onto separate sheets of paper and scanned them on a scanner. Using Photoshop, I then made the background color transparent and used layers to merge the image. This technique enabled me to do away with the whole idea of the subject copy and overcome the color reproduction problems normally encountered when printing the finished image. This means that the colors of the image parts obtained by scanning serve only as interim colors, making it possible to create a variety of expression, including coloration featuring a high degree of transparency not found in traditional reproductions of xylographic blocks. These types of data images capable of maintaining the texture and handmade feel of traditional xylography are referred to in this dissertation as digital woodcuts. Over the course of the study, I learned that some suitable color creation techniques are required for image data that is to be printed as a four color process job, and that digital xylography is one of well-suited techniques.
