Ink direct impact on the quality of Print Color accuracy and stability. Flexography used Water-based ink With low viscosity, low pollution features. Ink management mainly through the ink hue, color strength, light fastness properties of ink color detection to achieve the quality control parameters to eliminate color cast from the source. Ink can be detected and related materials suppliers, printing companies themselves may also be detected.

1, ink hue, color strength test

Hue, color strength is the ink detection of basic items, they are a great influence on the color of ink. Hue is the color of the specific characteristics of ink, in optics corresponds to a certain wavelength, the frequency of light, such as: red, yellow and blue hue refers to the ink. Ink color strength is a kind of another ink color changes affect the size of the degree. Deployment of spot-color ink, and when one of the original hue of ink or a change, bring up the spot color ink will change color. For example, when the original ink yellowish hue than before when the deployment of a spot color ink will have to increase the effect of yellow; if the original red color of ink stronger force, would have the effect of increased red. When this color deviation over a certain range, the visual can be found, leading to customer complaints. Therefore, ensuring the correctness of the printing ink hue and color strength of stability is very important to control print color.

2, hue test Provided on the new ink, generally to adjust its viscosity to the viscosity on the plane, with press proofing, to printing out this field color ink-like, or transfer this ink in the development of a good color wheel on the pressure drop a few drops to a certain degree of pressure, speed of printing surface drag, playing as a color display like a ribbon. Observed effect of these proofs, even if the ink layer is smooth, good color, has some luster, solid ink concentration, color same supplier standards Color Card (Can be made available ink factory) is consistent, indicated that this ink hue to meet the requirements. The desirability of a certain amount of the final inspection of the ink sealed to serve as a reference when the next wet hue detection of color samples.

, Who have used ink, this ink viscosity can be transferred to the optimum value, the color wheel to play with the development of good-like, with the last fight to retain qualified version of the standard color samples or color samples were compared, it can be an initial test hue line. Another method is to be detected with the last test qualified ink wet ink color samples, color wheel on the show about 1cm away from the few drops, parallel layout.

Paper edition at this time will stay in the fight of two adjacent ribbons, two ribbons can be controlled more accurately determine whether the same hue.
