Label printing requires secondary printing processing in the following situations:

Increased number of printing colors. Intermittent label machines (flat-to-flat, round-to-flat) are limited by the胶 roller structure.Our company can print up to four colors. If the label requires printing five or more colors, a two-step printing process is necessary: first, printing the four main colors, and then a second run to add the additional colors.

2. Increase Printing Area. The web width of intermittent label machines is fixed. To expand the printing area of labels, large-diameter rubber rollers (usually available in four-color, three-color, and two-color options on standard machines) must be used. As the ink application area of the rubber roller increases, the number of colors on the roller decreases. Therefore, to ensure large-area label printing, a secondary or multiple printing process is necessary.

3. Expand Equipment Functions: Some simple label equipment lacks functionality, such as gold stamping, die-cutting, and punching, which are all done on a single platform. To meet the diverse processing needs of labels, the roll paper must be processed twice or more at the same station to complete the entire label printing.

Ensure quality while reducing consumption.

Due to the multifunctional nature of the rotating machine, as long asA single process issue can lead to printing defects.The label tags have been invalidated, therefore, some printing factories ensure the quality of label printing by processing labels in a two-step method: printing first and then finishing, using the roll paper twice on the machine (this can be done on the same machine or on two separate devices). Although production efficiency is reduced, overall...Consumption reduced. Such choicesEnsured quality while reducing costs.
