Flexographic printing machine has the advantages of simple structure, convenient operation, strong material adaptability, low printing cost, energy-saving, environmental protection and pollution-free.With an in-depth understanding of flexographic printing's advantages and huge market prospects, many domestic printing companies have entered the flexographic printing field, introduced flexographic printing machines, and gained some flexographic printing experience.
Be sure to do analysis before purchasing
Before items on flexo printing machine starts, enterprise must do a good job in flexo printing market research, investigation and study of market demand for reasoning, a clear product positioning, put forward the feasibility of flexo printing. After formal involvement in flexographic printing, enterprises should also strengthen technical training. Providing people with training system from product design, plate making, printing to finishing the entire process, make the staff to master the basic theory of knowledge, so that they can use theory to guide practice, to make the flexo printing equipment operation, reduce rejection rate, improve the quality of products.
When selecting printing equipment, enterprises can compare and choose according to their own requirements, equipment configuration and price.On the domestic market at present, flexo printing equipment mainly from Spain, Germany, Italy and other countries the satellite flexo equipments imported equipment manufacturers, domestic shaanxi northerners printing machine co., LTD in 2009 to start producing satellite flexo machine drum.Different equipment manufacturers production of flexo printing equipment has its characteristic each, enterprise can according to the willingness to choose to suit their own development needs of flexo printing equipment, and form a complete set of equipment, such as repeat length plate can be adapted to different printing roller, etc., especially to adapt to the constantly changing packaging printing.

In flexographic printing process, the selection of flexographic materials and flexographic ink has great influence on flexographic printing effect.As a result of flexo printing using flexible plate belongs to the flexible plate, the printing dot enlargement phenomenon happens, inevitably lead to a small dot printing difficult, higher requirements in the production of high print, in the field to highlight cast defects such as dot, dot enlargement would appear, especially when ink inking amount is larger, will aggravate the degree of dot enlargement;Flexo ink inking amount is one-third of the amount of ink on the gravure printing ink, therefore in the highlights section to achieve the purpose of smooth color need high concentration of color ink, and water-based flexo printing ink color concentration is low, with gravure printing is quite need large amount of ink on color concentration.These problems need to be fully considered when selecting raw materials for printing enterprises. In addition, it is also necessary to select parts such as roller, ink scraper and adhesive tape.
Flexo printing prepress design, image processing, color separation, plate making, stick out version proofing, printing, finishing process, the process is different from the traditional intaglio printing process. printing enterprise need to test and summarized from the practice, master the flexo printing process.
Generally speaking, flexographic printing’s quality is mainly related to printing equipment, ink, printing materials, operating technology, roller, double-sided adhesive and printing plate. In practice, enterprises should carefully analyze and summarize the flexographic quality of printing ink, printing plate and other factors in different situations when the printing equipment is determined, and find out the best solution.
