Abstract

PURPOSE:To enable continuous printing without particularly strict registering, by a method wherein both end parts of a single unit pattern for printing a continuous pattern are printed by alternately using, in an overlapping manner, two kinds of halftone dots with dot density gradually reduced continuously. CONSTITUTION:For example, a printing material 4 is moved between an impression cylinder 1 and a blanket 2, and 8 printing ink is transferred from a plate 3 to the printing material 4 through the blanket 2, resulting in printing. At the first printing unit 5, printing in yellow is conducted by a conventional method while using halftone dots at an end part of a pattern. In the pattern thus printed by the first unit 5, the end part 7 has a printed density gradually lowered. Next, at the second unit 5', a unit pattern is printed while overlappingly printing the end part 7' in the same yellow color by using halftone dots with dot density varied oppositely to the above. Thus, the second end part 7' printed with a gradually increasing density overlaps with the first printed part, resulting in a predetermined printed density as a whole. Further, the same process is repeated at the third and latter units.

A typical conventional method of planographic printing means, for example, as shown in FIG. There is one for each color tone to be printed, and when the printing material (4) moves between the impression cylinder (1) and the bracket (2), the printing ink from the plate (3) passes through the bracket (2) and is coated. It is transferred to the printing material (4) and printed. And the above unit (5)
Usually, if there are four color tones, four units are arranged for each of the four color tones, and each predetermined color tone is printed. The first tooth (A) is an example in which four units (5), (5°), (5''), (5゛) are arranged linearly, but as shown in Fig. 1 (B), the pressure The above four units are arranged around the cylinder (1), and the printing material (4) is similarly placed between the impression cylinder (1) and the bracket (2).
There are also known types that allow movement between the two. In either type, the first unit (5) prints a predetermined color, for example, yellow, and then the second
In the th unit) (5'), a red part is printed, and similarly, in the third and fourth units, a predetermined color tone is printed to print one predetermined pattern (bang). Note that the number of units is provided in accordance with the number of color tones, and is not limited to four units.

7. When printing a so-called long continuous pattern using such a printing method, it is very difficult to align the pattern, and the pattern inevitably overlaps in part or breaks off, resulting in chipping. More specifically, as shown in FIG. 2(A), for example, when printing a long object having continuous patterns (6), (6″), (6″), the pattern (6″) as shown in FIG. 2(B) is printed.
), (6°) and a continuous pattern is not formed, or as shown in Figure 2 (C), the edges (
7) and (7゛) overlap, and only that part is printed very darkly. This drawback becomes a very serious problem especially when printing long objects continuously.

For example, when printing using a unit as shown in FIG. 1(A), the first unit (5) prints halftone dots at the edges of the pattern, and the other patterns are printed in yellow, for example, in the usual manner. do. As shown in FIG. 3(A), the pattern printed by this first unit (5) is printed with a gradually lighter print density at its edges (7) due to the use of halftone dots. ), the desired pattern is printed. Next, the second unit (5") prints the unit pattern using the same yellow color and overlapping the edges (7") using halftone dots with reversed halftone density. In this case, The halftone dot density is reversed, and the printed part is printed gradually from the dark part at the first end (7) to the printed part which is printed gradually from the light print at the second end (7゛). The printed parts will overlap, and the whole will be printed at a predetermined density.For convenience of explanation, only the density of the pattern at the edge (7) printed by the first unit (5) will be printed. The printed end (7') of the second unit (5') is as shown in Figure 3 (B). In the invention, these end portions (7) and (7゛) are printed overlappingly, so even if there is a slight overlap or there is a chip in the continuous pattern, it is possible to print the end portions (7) and (7゛) overlappingly. Since both ends (7) and (7") are printed overlappingly, the overlapping area is a dark area and a light area, making it possible to print at the desired density. , and because the edges are printed overlappingly, no printed parts or chipping occurs at all. stop ,
In the overlapping portion, since the dark portion and the thin portion overlap, the overall density remains the same as the predetermined density.
