英文回答：

Ink Volume Calculation for Flexographic Printing.

Calculating the amount of ink required for flexographic

printing is a crucial step in ensuring optimal print

quality and efficient production. The ink volume is

determined by several factors, including the substrate, ink

type, print coverage, and printing speed. The following

formula can be used to calculate the ink volume:

Ink Volume (mL) = Print Coverage (%) x Substrate Area

(m²) x Ink Film Thickness (µm) / Ink Density (g/mL)。

Factors to Consider:

Substrate: Different substrates, such as paper, film,

and foil, have varying absorption rates and surface

properties, which affect the ink volume required.

Ink Type: Water-based, solvent-based, and UV-curable

inks have different viscosities and flow characteristics,

influencing the ink film thickness.

Print Coverage: The percentage of the substrate area

that will be covered with ink.

Printing Speed: The faster the printing speed, the

thinner the ink film must be to prevent smudging or

ghosting.

Ink Film Thickness: The thickness of the ink layer on

the substrate, typically measured in microns (µm).

Ink Density: The mass of ink per unit volume, measured

in grams per milliliter (g/mL).

Example:

To calculate the ink volume required for a flexographic

printing job on paper substrate with a print coverage of

70%, substrate area of 50 m², ink film thickness of 5 µm,

and ink density of 1.2 g/mL:

Ink Volume (mL) = 70% x 50 m² x 5 µm / 1.2 g/mL =

187.5 mL.

柔版印刷油墨用量计算。

计算柔版印刷所需的墨量是确保最佳印刷质量和高效生产的关

键步骤。墨量由多种因素决定，包括承印物、油墨类型、印刷覆盖

率和印刷速度。可以使用以下公式计算墨量：

墨量（毫升）= 印刷覆盖率（%）× 承印物面积（平方米）×

油墨膜厚（微米）/ 油墨密度（克/毫升）。

考虑因素：

承印物，不同的承印物，如纸张、薄膜和箔纸，具有不同的吸

收率和表面性质，这会影响所需的墨量。

油墨类型，水性、溶剂型和 UV 固化油墨具有不同的粘度和流

动性，影响油墨膜厚。

印刷覆盖率，承印物上将被油墨覆盖的面积百分比。

印刷速度，印刷速度越快，油墨膜必须越薄，以防止污迹或重

影。

油墨膜厚，承印物上油墨层的厚度，通常以微米 (µm) 为单

位测量。

油墨密度，单位体积的油墨质量，以克/毫升 (g/mL) 为单位

测量。

示例：

计算在纸质承印物上进行柔版印刷作业所需的墨量，印刷覆盖

率为 70%，承印物面积为 50 平方米，油墨膜厚为 5 微米，油墨密

度为 1.2 克/毫升：

墨量（毫升）= 70% × 50 平方米 × 5 微米 / 1.2 克/毫升

= 187.5 毫升。
