摘要： PROBLEM TO BE SOLVED: To obtain a process for producing a liquid crystal panel for gradation display and for high contrast by controlling the circumferential speed of an anilox roll at printing and the circumferential speed of the anilox roll at milling operation so as to satisfying a specific relation, thereby forming uniform alignment layers and insulating films. SOLUTION: A servo motor 8' is used as a drive source for milling operation of a flexographic printing machine and a drive source for printing operation. A plate cylindrical 5 is so disposed that the plate cylinder comes into contact with the anilox roll 2 when a stage 7 advances to execute printing and that the plate cylinder parts from the anilox roll 2 when the stage 7 retreats. The circumferential speed of the anilox roll 2 at the printing operation, defined as V1, and the circumferential speed of the anilox roll 2 at the milling operation, defined as V2, are so controlled as to satisfy the relation 0

摘要： PROBLEM TO BE SOLVED: To form a uniform film by adequately and uniformly squeezing a liquid on a plate or roll for printing by a method wherein a whole plane part of a doctor blade is uniformly pressed and held by an inclined face in a wedge structure such that a linearity in a tip of the doctor blade is not disturbed. SOLUTION: A doctor blade 10 is disposed to a lower side 11b of a V-shaped inner section of a receiving frame 11 and a pressing body 12 is inserted to the V-shaped inner section of the receiving frame 11 such that an inclination face 12a of a lower side of the pressing body 12 contacts the doctor blade 10. A bolt 13 is screwed into a female screw 11a of the receiving frame 11 from a right side face 12c of the pressing body 12 to a hole 12d in the condition that the doctor blade 10 and pressing body 12 are in contact with each other and the doctor blade 10 is supported by the lower side 11b of the receiving frame 11 and the inclination face 12a of the lower side of the pressing body 12. As a result, a component force is generated on the inclination face 12a and the whole part of the doctor blade 10 is roughly uniformly held by a surface pressure of the wedge.

摘要： PURPOSE:To solve the formation of nonuniform film quality and to provide the liquid crystal panel of a high contrast for gradation display by uniform film quality in a printing stage for the oriented films, insulation films, etc., of the liquid crystal panel. CONSTITUTION:A servo motor 8' is used as a kneading motor of a printing machine and a stage traveling region is formed by extending this region longer than heretofore. As a result the uniformly oriented films and insulating films are formed and, therefore, the production of the liquid crystal panel of the gradation display and the high contrast is possible and this process is extremely advantageous for practicability.

摘要： PROBLEM TO BE SOLVED: To provide a holding mechanism for an oscillatory die copying member for transferring without irregularity by constant velocity squeegeeing. SOLUTION: A preloading mechanism 40 is provided between a first block 5 mounted with a printing blade 1 and a second block 9 for oscillatorily holding the block 5. A steel ball 44 engaged with the block 5 is brought into pressure contact with a clamping pin 41 engaged with the block 9 by a leaf spring 46 of the mechanism 40 to bury a clearance to prevent change of a squeegeeing speed due to generation of vibration by dynamic friction force change of the blade 1 and an opposite side contact surface of a printing plate or the like.
