Select the box printing color management system

Ink composition and function: water-based ink is processed by the water-soluble resin, advanced pigments, solvents and additives from. Its hue depends on the nature of the pigment, superficial pigment is required to have a beautiful luster, strong coloring power and conceal forces, better patience and a high degree of slack. In order to obtain better printability of ink, often use various types of ink additives to adjust the movement of the ink, monotonous and viscous according to substandard conditions. Select Ink quality factor more use of defective, will bring a series of quality problems, buy and use should pay careful analysis, discriminant shape their quarrel and make adjustments according to the situation, in order to guarantee its excellent printability .

 

 

In printing, the ink has a certain viscosity is deadlocked normal transfer, the transfer of ink needs dictate. So shallow high-grade ink viscosity control in about 20 ± 5 seconds, the difference in viscosity would constitute a printed color depth discord. Theoretical production process, according to Cheng was substandard and temperature, PH value of ink on the machine or control adjustable between 8.0 to 9.5.

 

 

Ink Dispatcher: Dispatcher first hypothesis refers ink color ink color match. In packaging products printing, ink used in color to spot color flat painted mainly arrive double vision and security of the consequences.

 

 

These undesirable spot color, not by cyan, magenta, yellow, black four-color overprint made, often can not find the original ink directly applicable, shall be based on the production situation skill personnel, were disproportionate to the original ink dispatch acquired .

 

 

Ink color assignment is based on the subtractive color process affair, that can use any of the three primary colors of color disproportionately doping dispatched from, and think its hue, lightness and saturation of the three basic attributes. When you want to select the color ink, and the ink itself thinking hue, gloss, color strength, power and other elements based on the theory conceal the printing process, the ink film thickness, printing substrate and other conditions.
