How to expand the plate making performance of photosensitive resin plate (Part 2)

the application of hybrid am in the flexographic CTP workflow effectively eliminates the need for jumping curves, and at the same time, due to the sharp points, the point expansion is minimized, which is the inherent characteristic of digital printing plate. Further improvements in quality can be achieved by using element based allocation tools. It allows you to choose to use hybrid am in the right place without forcing you to use it in the whole design

another new technology is hyperflex (TM) plus, which is a supplement to hybrid am plus

when the photosensitive resin plate is exposed by amplitude modulation plus, the regularly arranged points support each other in the process of forming on the plate, resulting in an effect commonly known as "bridging". However, when using other alternative addition technologies, such as hybrid am addition, the number of highlights is reduced, thus reducing the overall support. This increases the pressure on each idea and affects the reproduction of the midpoint in the development and printing process

hyperflex helps the photosensitive resin plate form dots or image elements. It can be seen from the following image that the use of hyperflex is helpful to improve the plate making process

in Figure 3, we try to break the limitations of the plate making process. In the mediation of Wald gerl, CEO of 1% LuChen new materials, and Xiao Jingjie, chief professional chief engineer of GAC Group Automotive Engineering Research Institute, we generate 25 micron ideas with 120lpi. As you can see, the dots on the printing plate are not well formed, so there is a great risk that the printing effect is far from what you expected

in Figure 4, hyperflex plus technology is only applied to the highlight area, helping to reduce the depth of bumps between points, expand the shoulder foundation, so that points can be formed well, and small points that cannot be obtained by using the existing technology can be obtained. Another advantage is that the surface area of the dots remains unchanged, so the hyperflex processing process will not cause unwanted dot increases on the printed matter

Figure 5: plate surface

Figure 5 below shows that there will be a cross part when hybrid am is applied to the whole plate. Note that the normal maintenance and installation of highlight equipment is a very important part. All points have the same static bending strength, but some are isolated and unsupported. These isolated points cannot be well formed on printed matter

Figure 6: on the contrary, Figure 6 shows the same plate added with hyperflex. As a result, in the highlight area, the slope is lower, giving more support to isolated points, so as to obtain excellent printing effect

in short, new digital technologies continue to enhance the plate making performance of photosensitive resin plates. Various regions have also introduced regulations related to golf corruption. Improving hybrid am plus and combining hybrid am plus with hyperflex plus are examples of how to apply science and technology to continue to enhance the competitive strength of flexo printing
