C2 Determination of optimal solid density (D)
GB/T 1451093
The best solid density of the printing ink is important for improving printing quality and stabilizing printing parameters. The optimal solid density is closely related to the printing contrast. The solid density that provides the maximum K value should be selected as the optimal printing density. The optimal solid density is obtained by graphical method. By calculating the value of a certain printing color under the condition of D., the printing contrast fastness line of the tested printing color can be drawn. The D value corresponding to the top of the line is the optimal solid density of the tested printing ink, see Figure C1.0.sr
C3 Determination of dot enlargement value 4
The dot enlargement value refers to the natural expansion of the dot area formed by the increase of printing pressure during the proofing or printing process of the printing plate. The determination formula is as follows:

Determination of resolution and light tolerance of C4PS plate 1—10,
10-yuan×100%
The resolution of PS plate is determined by KPMSI test strip produced by FOGRA. Through experimental light exposure, the exposure lines of negative and positive lines can be drawn on the HOGRA plate-making table. The intersection of the negative and positive curves is the resolution of the tested PS plate, which is expressed in um. From the intersection of the representative resolution, a line perpendicular to the horizontal axis is drawn. The intersection of the line and the horizontal axis represents the minimum exposure value of the tested PS plate. After adding 4um to the resolution, a vertical line perpendicular to the horizontal axis is drawn from the intersection of the positive noise light curve. The intersection of the vertical line and the horizontal axis represents the maximum exposure value of the tested PS plate. The interval between the minimum and maximum noise light values is the light tolerance. For measurement details, see the KPMSI test strip manual. Additional notes:

Multifunctional quality inspection strips that combine visual evaluation and test evaluation are called control strips. There are two commonly used control strips, FORA control strips and the first generation Brunner control strips. B2FOGRA test strip

The solid density that provides the maximum K value should be selected as the optimal printing density. The optimal solid density is obtained by graphical method. By calculating the value of a certain printing color under the condition of D., the printing contrast fastness line of the tested printing color can be drawn. The D value corresponding to the top of the line is the optimal solid density of the tested printing ink, see Figure C1.0.sr

Determination of resolution and light tolerance of C4PS plate 1—10,
10-yuan×100%
The resolution of PS plate is determined by KPMSI test strip produced by FOGRA. Through experimental light exposure, the exposure lines of negative and positive lines can be drawn on the HOGRA plate-making table. The intersection of the negative and positive curves is the resolution of the tested PS plate, which is expressed in um. From the intersection of the representative resolution, a line perpendicular to the horizontal axis is drawn. The intersection of the line and the horizontal axis represents the minimum exposure value of the tested PS plate. After adding 4um to the resolution, a vertical line perpendicular to the horizontal axis is drawn from the intersection of the positive noise light curve. The intersection of the vertical line and the horizontal axis represents the maximum exposure value of the tested PS plate. The interval between the minimum and maximum noise light values is the light tolerance. For measurement details, see the KPMSI test strip manual. Additional notes:
