Abstract
The small automatic two colour printer VS-1000 which we have developed is characterized by introducing Toray Waterless Plate and full electronic control of mechanisms, and also we have developed, as one of the key technologies of the printer, “VS-1000 total resister pin system”. This system makes it possible for automatic plate changing to be compatible with resister pin system, and consists of two sub-systems “Plate making resister pin system” and “Automatic plate feeding and postioning system”. In this paper, we mainly explain the construction and effect of the latter “Automatic plate feeding and postioning system”. The greatest feature of this system is to introduce Toray Waterless Plate with polyester (PET) base film, named “Film Base Waterless Plate”. In conclusion, in the case of using a processed “Film Base Waterless Plate” repeatedly, the repeatability of the printed posion due to this “Automatic plate feeding and positioning system” is within ±25μm, Therefore, the total accuracy of “VS-1000 total resister pin system” is, we suppose, about ±45μm.
