Research on printing quality of paper with different properties in inkjet printing (10)

2 Analysis of the printing results of printer 2: in the range of 100~75% full page concentration, opacity and whiteness show a negative relationship with color difference, and in cyan, magenta, impact testing machine, generally the whole set of equipment, yellow shows a negative relationship, which is more obvious. When opacity and whiteness increase, the color difference decreases, and black has no relationship. The relationship between gloss and color difference is not obvious, and the curve changes irregularly. Because the variation of gloss itself is difficult to control in this experiment, it is impossible to judge the relationship between gloss and color difference. (as shown in Figure ~ Figure)

3 Compare printer 1 and printer 2:

compare the paper properties of opacity, whiteness and gloss with the color difference, and compare them with CMYK printing color gamut. The color difference of printer 2's yellow and black is less than that of printer 1, while the color difference of cyan and magenta of printer 2 is greater than that of printer 1, which have better colors respectively. According to the overall numerical analysis, the color difference of printer 1 is small. (as shown in Figure ~ Figure)

(II) analysis of color difference and paper properties under the concentration of RGB regions

1 Analysis of the printing results of printers 1 and 2:

in the range of concentration (75 ‰ whitening ~100 ‰ pure color ~75 ‰ blackening), the opacity and whiteness show a negative relationship with the color difference, and the negative relationship is obvious in red, green and blue. When the opacity and whiteness increase, the color difference decreases. The relationship between gloss and color difference is not obvious, and the curve changes irregularly. Because the variation of gloss itself is difficult to control in this experiment, it is impossible to judge the relationship between gloss and color difference. (as shown in Figure ~ Figure)

2 Compare printer 1 and printer 2:

compare the three paper properties and color differences of transparency, whiteness and gloss in the code for acceptance of construction quality of stainless steel structures GB 50205 (2) 001, and compare them with each other in RGB color gamut. The red and green color differences of printer 1 are smaller than those of printer 2, especially when it is red, and the two are the same when it is blue. Based on the overall numerical analysis, the color difference of printer 1 is smaller. (as shown in Figure ~ Figure)
