PURPOSE:To contrive higher productivity, by making a flexible tube by using a photo-curable type ink. CONSTITUTION:The photo-curable type ink is prepared by using a polyester acrylate oligomer, a urethane acrylate oligomer, a polybutadiene oligomer, an epoxy acrylate oligomer or the like as a main constituent, adding a reactive diluent, a photo-reaction initiator and a white pigment to the main constituent, and further adding a silica filler and a surface-improving agent to adjust the viscosity to 20-100 poise. An ink is preliminarily applied to stencil parts 6,... of a screen plate 2, and the flexible pipe 8 is brought into rolling contact with the lower side of the screen plate 2. Squeezee 18,... are rotated in the direction of arrow B and is pressed against the stencil parts 6,.... When a screen frame 3 is moved in the direction of arrow A, the tube 8 is rotated by one revolution on rollers 12, 12 while making rolling contact with the screen plate 2, whereby the tube 8 is marked with graduations 30 incised by white lines. |
