Gravure printing and flexo printing are the two preferred printing processes in the current high-quality consumer packaging market. The two processes have their own characteristics and advantages. Shandong Printing Factory provides printing guarantee for various packaging products. The advances in flexo printing skills in recent years have also provided consumer packers with a new option to complete high-quality printing. Choosing the appropriate printing process needs to consider the cost, packaging type, printing quality and shopping mall objectives and other factors. Next we will comment in detail on the key points to consider in selecting packaging and printing process requirements.
Gravure Printing Quality
Gravure printing, the use of carved metal drums to carry printing pictures and texts, has always been considered to be the primary process to achieve high quality printing. Full color, precise reproduction of pictures and texts, bright tone reflects perfection, the whole printing process can maintain stability and common printing role. For mass printing over 200,000, gravure printing has a greater cost advantage. For medium-sized orders, gravure printing also has a cost advantage compared with flexo printing competition.
Gravure printing has always been used for certain types of packaging. For example, food packaging cooking bags are usually sterilized in the printing process, so gravure printing is needed to meet the relevant specifications of solvent residue in packaging. Gravure printing quality is incomparable, generally at a glance can be high-quality products and high-end brands and low-end products.
High Resolution Flexography
Flexographic printing uses flexible photosensitive resin plate, and relief letters convey ink to the printing material. In recent years, flexographic printing has been breaking through in the quality of printing, and has become the primary competitor in gravure printing in many fields. A series of technical advances, including printing press function, screen roller, plate, dot shape and ink supply system, lay the foundation for the completion of a new generation of high-resolution flexo printing skills.
The advantage of high resolution flexo printing compared with general flexo printing is similar to the difference between high resolution TV and general TV. The resolution of high resolution flexo printing can reach 4000ppi2, while that of standard flexo printing is basically 2450 ppi2. High resolution flexo printing is based on flat-top dots rather than traditional dome dots. Dome dot printing usually has uneven edges and poor saturation of color areas, while the new flat-top dot reflects more vivid pictures and simpler text analysis.
The advantages of high resolution flexo printing include fuller field, better ink handling, softer highlight transition, better reproduction of high quality pictures, and the ability to reproduce more than 150 LPI screen lines.
Smaller orders, faster replacement
Nowadays, all new flexographic presses can fulfill orders of at least 15,000 to 20,000 prints. Flexographic printing can take on smaller orders because its printing version is cheaper and easier to replace than gravure drum. High resolution flexo printing can complete the rapid replacement of printing operations and shorten the time period from design to printing. These advantages bring more choices for packers, especially in the market environment where packaging stores are focusing on personalization, regionalization and regular promotional activities.
Wide gamut printing process
Another innovation of flexo printing by wide-area printers. Wide-area printing uses a coloring process and adds orange, green and purple to the basis of standard four-color printing (yellow, product, green and black). Wide gamut printing uses a combination of one or seven colors to represent all printing pictures, eliminating the use of spot ink. It can reproduce 85% of 1800 pan tones, while the standard four-color printing can only reproduce 50%.
Wide gamut printing process provides packaging designers and developers with more color selection. Can complete more disorderly color printing, improve the authenticity of the picture, more attractive tones, more bright, softer. Packaging managers can choose wide-area printing process to complete more visible product role and improve the contrast between product and background color.
Omnidirectional processing capability
If the company needs to use flexographic and gravure packaging printing processes together, it is particularly important to find a packaging company that can produce both processes together. For example, the same manufacturer can facilitate business harmony and communication. In addition, brand managers prefer that all packaging production, including printing and post-processing, be done in one factory rather than outsourcing to other companies.
Gravure printing and high resolution flexo printing have cost advantages in various packaging printing fields. Packaging and printing suppliers can generally provide professional assistance in selecting the best process for detailed orders.
