Previously, we indicated that athymic BALB/c-nu/nu (nude) mice that had been repeatedly treated with 2,4,6-trinitrochlorobenzene (TNCB) failed to exhibit chronic scratching behavior in spite of the accumulation of dermal mast cells in the lesion. The mice also failed to produce specific IgE or potent dermatitis. In the present study, therefore, we aimed to(More)
Mezzotint is one of the copperplate printing techniques developed around Europe during the Middle Ages, in which an entire plate surface is roughened by various steel tools such as rockers, halftone combs. A rocker is used to create many dots while burrs rise out of the plate. Burrs hold some additional ink making slight blots and blurs at the print. After(More)
Mezzotint[Leaf 1984] was developed as one of the traditional copperplate printing techniques in the mid-17th century. It can realize an effect of various gray tones as shown in fig. 1a. To acquire the effect, a copper plate is set up going through three phases: roughening, scraping, and burnishing. In the roughening phase, a rocker is used to create many(More)
In this paper we propose a method to synthesize a virtual copperplate print image based on physical model as a non-photorealistic rendering in Computer Graphics. In particular we pick out the drypoint from many existing copperplate printing techniques. A drypoint print has a remarkable feature that ridged burrs are arising out of the copperplate and the(More)
