Problems solved by technology

For some special glazing with slightly higher requirements on hand feeling and texture, it can be realized by reducing the line number of anilox roller, but too low line number of anilox roller will lead to poor printing leveling and affect the overall surface effect. Increase the difficulty of tuning
For some special surface effects with a strong sense of accumulation, such as embossed oil effect and engraving effect, it can only be realized by silk screen printing or gravure printing. The efficiency is low and the printing accuracy is not good enough

Embodiment 1

[0032] Figure 1-2 The offset coated resin plate with high ink loading shown includes a resin plate substrate 1 and a photosensitive layer 2; the surface of the photosensitive layer 2 is provided with a number of groove-like structures arranged in a certain form.

[0033] Wherein, the groove structure is a dotted groove 3 . The diameter of the dotted grooves 3 is 0.1 mm, the depth is 0.03-0.05 mm, and the distance between the dotted grooves 3 is 0.03 mm. The dotted grooves 3 can be arranged in a "well" shape, such as image 3 As shown, it can also be arranged in a "honeycomb" shape, such as Figure 4 As shown, it is obvious that other arrays or irregular arrangements can also be used.

Embodiment 2

[0035] Figure 5-7 The offset coated resin plate with high ink loading shown includes a resin plate substrate 1 and a photosensitive layer 2; the surface of the photosensitive layer 2 is provided with a number of groove-like structures arranged in a certain form.

[0036] Wherein, the groove-shaped structure is a strip-shaped groove 8 and is linear, and the cross-section of the strip-shaped groove is trapezoidal, with a top width of 0.2-2.6mm and a bottom width of 0.6-3.0mm. The slot pitch is 0.2 mm. Apparently, the cross-section can also be arc-shaped or other suitable shapes, and the strip-shaped grooves can also be circular or polygonal, and the strip-shaped grooves can be arranged at equal or unequal intervals.

Embodiment 3

[0038] Figure 8 The offset coating resin plate with high ink loading shown, wherein, the groove-like structure is a strip groove and is a quadrilateral, obviously also can be a triangular ( Figure 9 shown), pentagonal or hexagonal ( Figure 10 shown), etc. The rest are basically the same as in Embodiment 2.

Abstract

The invention discloses a high-ink load offset print coating resin plate, and aims at providing a high-ink load offset print coating plate which is convenient to use. The high-ink load offset print coating resin plate comprises a resin plate base material and a photosensitive layer, wherein a plurality of groove-shaped structures which are arranged according to a certain form are arranged on the surface of the photosensitive layer. According to the high-ink load offset print coating resin plate, the ink load can be greatly improved under the condition of a same anilox roller line number through changing the surface structure of the resin plate, and the levelling property of the ink is not influenced.

Description

technical field [0001] The invention relates to the technical field of footprint equipment, in particular to an offset printing coated resin plate with high ink loading capacity. Background technique [0002] At present, the printing surface of the offset coating resin plate on the market is 100% flat, and the ink loading capacity is small, which can only meet the requirements of ordinary coating and glazing, and is suitable for products that require a thinner accumulation effect. For some special glazing with slightly higher requirements on hand feeling and texture, it can be realized by reducing the line number of anilox roller, but too low line number of anilox roller will lead to poor printing leveling and affect the overall surface effect. Increase the difficulty of tuning. For some special surface effects with a strong sense of accumulation, such as embossed oil effect and engraving effect, it can only be realized by silk screen printing or gravure printing. The effi...
