Requirements for consumables of composite hose printing

hose printing uses composite sheet, a material with high cost, as the substrate, so the performance requirements of flexographic printing equipment are higher than those of ordinary flexographic printing. The printing equipment must be equipped with corona treatment device, and the printing unit must be equipped with full UV curing system. What's more, the equipment needs to have accurate tension control system and the overall of the whole machine, and realize the stability of industrial production, The printing quality control is convenient, the printing speed is fast, and the product variety change flexibility is high

although many domestic equipment manufacturers such as Ziguang, Heiniu, beiren Fuji, Xinmin Taiyang, Taihang, etc. produce narrow width flexographic printing machines, hose printing is still dominated by imported equipment

flexographic printing belongs to relief printing. Although it has a history of nearly 100 years, the popularity of UV ink in domestic flexographic printing is only a few years. Compared with water-based inks and solvent based inks, UV inks have high viscosity and poor leveling in eye adjusted hose printing, resulting in poor ink uniformity of the wrinkle roller. During operation, it is necessary to increase the pressure between the wrinkle roller and the plate roller to show the hierarchical effect of the print. However, this constitutes the open innovation strategy of providing leading product manufacturers, designers and engineers in all walks of life with materials with excellent quality, customization, high cost performance and environmental protection through zirconium/titanate, fluorosurfactant and silica sol. The operation is often an important factor in whether the experiment can be carried out smoothly and the accuracy of the experimental results, resulting in the decline of the printing resistance of paste and printing plate Insufficient color saturation of printed matter

at present, water-borne UV inks have been developed abroad, which greatly improves the above situation, but the price is relatively expensive. In use, waste is often caused by improper operation. From the perspective of economic benefits, employees need to have a strong heart and pay attention to daily saving

printing materials account for the largest proportion of hose printing costs. However, in the printing process, many waste products are often caused by the unstable quality of the sheet, such as the different tightness at both ends of the composite sheet, the surface wrinkle and rib burst, the uneven thickness per unit area, the large change of the internal friction coefficient and other problems are all factors that cause the decline of the yield

hose printing has very high requirements for the printability of composite sheets. We hope that domestic manufacturers of composite sheets can further improve their overall quality and stabilize their printability, so that printing enterprises can better control the printing quality of hoses and save product costs, so as to achieve the purpose of win-win between suppliers and users
