First printing plate and second printing plate
View Patent ↗Disclosed are a printing plate and a mirror thereof, the printing plate including: printing portions for transferring an immersed solution, the printing portions being formed flat and arranged at regular intervals on one side of an upper part of the printing plate; and non-printing portions corresponding to a remaining area other than the printing portions, the non-printing portions being formed with at least two concavities and convexities respectively and arranged at regular intervals on the other side of the upper part of the printing plate.
1. A printing plate comprising:
printing portions for transferring a solution, the printing portions each being formed smoothly so as to not include any bumps, the printing portions being arranged at regular intervals on an upper part of the printing plate; and
non-printing portions corresponding to a remaining area of the printing plate other than an area where the printing portions are disposed, the non-printing portions each being formed with a plurality of concavities and a plurality of convexities, the non-printing portions being arranged at regular intervals on the upper part,
a distance between adjacent ones of the convexities of the non-printing portions being smaller than a total length of one of the printing portions.
2. The printing plate as claimed in claim 1 , wherein the concavities and the convexities of the non-printing portions are formed in any one of a triangular shape, a quadrangular shape, and a semicircular shape.
3. The printing plate as claimed in claim 1 , wherein a surface energy of the concavities and the convexities of the non-printing portions is determined by any one of
the sizes of the concavities and the convexities of the non-printing portions,
the shapes of the concavities and the convexities of the non-printing portions,
the depths of the concavities and the convexities of the non-printing portions, and
the spacings of the concavities and the convexities of the non-printing portions.
4. The printing plate as claimed in claim 3 , wherein a material of the printing plate includes at least one of silicon, glass, quartz, organic materials, inorganic materials, and polymers.
5. The printing plate as claimed in claim 1 , further comprising an embossment and an intaglio forming a step height therebetween.
6. The printing plate as claimed in claim 5 , wherein the non-printing portions are formed in the embossment, and the printing portions are formed in the intaglio.
7. The printing plate as claimed in claim 5 , wherein the printing portions are formed in the embossment, and the non-printing portions are formed in the intaglio.
8. The printing plate as claimed in claim 1 , wherein the printing plate is used in any one of a gravure printing apparatus, a screen printing apparatus, and a micro-contact printing apparatus.
9. The printing plate as claimed in claim 1 , wherein the printing portions are arranged at the regular intervals on one side of the upper part, and the non-printing portions are arranged at the regular intervals on another side of the upper part.
10. The printing plate as claimed in claim 1 , wherein a surface of the printing plate is furthest away from each of the non-printing portions and the printing portions, the printing portions each being a distance from the surface, that is a smallest distance therebetween, that is equal to or greater than a distance from the surface to the non-printing portions.
11. The printing plate as claimed in claim 1 , wherein along a straight line, each of the printing portions is disposed between two of the non-printing portions.
12. A printing plate comprising:
printing portions for transferring a solution, the printing portions being formed smoothly so as to not include any bumps, the printing portions being arranged at regular intervals on an upper part of the printing plate; and
non-printing portions corresponding to a remaining area of the printing plate other than an area where the printing portions are disposed, the non-printing portions each being formed with a plurality of concavities and a plurality of convexities, the non-printing portions being arranged at regular intervals on the upper part,
a surface of the printing plate being furthest away from each of the non-printing portions and the printing portions, the printing portions each being a distance from the surface, that is a smallest distance therebetween, that is equal to or greater than a distance from the surface to the non-printing portions.
13. The printing plate according to claim 12 , wherein a distance between adjacent ones of the convexities of the non-printing portions being smaller than a total length of one of the printing portions.
