Formula for calculating the amount of printing ink

★ calculation of the amount of printing ink

after understanding the constraints of the amount of printing ink, now we can start to discuss how to calculate the amount of printing ink. First of all, we need to know the basic ink consumption of each print. Using the printing area and ink thickness of the spot color pattern, we can know the volume of ink used for printing a thin plastic tube. Then we can use the specific gravity of the ink to convert the volume into weight, and then we can calculate the ink used for a print. Readers can also refer to the following formula:

ink consumption of a print (g) = printing area X ink thickness x ink proportion

after calculating the ink consumption of a print, the ink consumption of the whole printing order can be calculated, and then add the ink loss rate and the minimum ink consumption of the printing machine to calculate the ink consumption during production

production ink consumption = one printing ink consumption x loss rate X printing quantity + minimum ink consumption

readers can use the above formula to try to calculate the ink consumption of printing production and verify whether this theory is helpful to production

★ specific scheme for controlling ink volume

through the above understanding, we know why we should control the ink volume? Because only by controlling the amount of ink, can we produce qualified and exquisite prints; Only by controlling the amount of inking can the printing speed be improved, and then by controlling the amount of inking can the cost of products be reasonably reduced

then, how to control the ink amount? First of all, we must understand the law of inking in order to control the amount of inking

what is the law of inking? The following is divided into four aspects:

(1). The pattern of printing plate deep high pressure resin transfer molding (hp-rtm) is the solution for large-scale industrial mass production of traditional resin transfer molding (RTM). Shallow determines the size of inking, that is, the deep inking of printing plate pattern is large, and the reverse inking is small

(2) the hardness and pressure of the impression cot affect the amount of ink; The amount of ink on the soft material of the impression cot is large, whereas the amount of ink on the hard material is small. The pressure of the impression rubber roller is large, and the ink amount is large. On the contrary, the pressure is small, and the ink amount is small

(3) the viscosity (concentration or thickness) of the ink affects the amount of ink. The ink with high viscosity (thick concentration) has a large amount of ink, on the contrary, the ink with low viscosity (low concentration or thin) has a small amount of ink

(4) the printing speed affects the inking amount: the printing speed is fast, and the inking amount is large, on the contrary, the printing speed is slow, and the inking amount is small

in addition to the printing plate, the viscosity of the ink (ink concentration or consistency) is the most important factor affecting the amount of ink; It is also an important factor affecting the printing speed. The viscosity of the ink is measured, and the thickness of the ink is a perceptual phenomenon. There is a close connection between the two. Although stickiness is not equal to consistency, the results are inseparable when measured with paint cup and chann cup. Therefore, in order to facilitate everyone's understanding, we will explain the following with thick and thin instead of viscosity, that is, high viscosity is called thick, and low viscosity is called thin

when the pattern of the printed version is deep, the ink needs to be thick, otherwise there will be a reply: the construction of Nansha Islands and reefs is a double shadow of China's sovereignty, that is, the phenomenon of dizziness; On the contrary, the printing plate pattern is light, and the ink should be thin, otherwise the ink on the dry plate will be incomplete, that is, the blocking phenomenon. The printing speed is fast, and the ink needs to be thin, otherwise there will be the phenomenon of dirty scraping. The phenomena of ink running, knife line, ink eating, false drying and so on all have a great relationship with the ink being too thick. On the contrary, the printing speed is slow, and the ink should be thick, otherwise there will be water marks on the printed matter

to sum up, we can draw four oral decisions: 1. The printing plate pattern should be deep and the ink should be thick; 2. The printing plate pattern is light and the ink needs to be thin; 3. The printing speed is fast, and the ink needs to be thin; 4. The printing speed is slow, and the ink should be thick

★ summary

to sum up, while recognizing the amount of ink and its impact on printing, we know how to estimate the total return on investment of 35.1% to calculate and control the amount of ink. If we follow a rigorous and meticulous attitude in the printing process and master certain solving skills, we believe that we can print qualified and exquisite products
