Abstract
Abstract An abstract pattern plate-making system removes an undesired pattern from an endless pattern in the process for making a plate for printing abstract patterns on architectural materials. For this purpose, it has a scramble processing part 10 and a pixel copy processing part 11. The scramble processing part 10 divides endless pattern data into blocks and repeats processing in which pattern data in two blocks selected at random from among the divided blocks are combined together by a composition technique using mask data having a predetermined pattern, thereby removing an undesired pattern. The mask pattern size may be either smaller or larger than the block size. The mask pattern may be a multi-valued pattern. Further, when the endless pattern is divided into blocks, the blocks may be allotted so as to be a little offset from the endless pattern. The pixel copy processing part 11 first prepares mask data on the basis of designated pattern data in the endless pattern data and then repeats processing in which pixel data at a designated position is copied to another designated position on the basis of the prepared mask data, thereby removing an undesired pattern.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
52 words
An abstract pattern plate-making system comprising means for removing an undesired pattern by dividing endless pattern data into blocks and then repeating processing in which pattern data in two blocks selected at random from among said divided blocks are combined together by a composition technique using mask data having a predetermined pattern.
Claim 2
Dependent Claim
18 words
An abstract pattern plate-making system according to Claim 1, wherein said mask data is multi-valued data having gradation.
Claim 3
Dependent Claim
16 words
An abstract pattern plate-making system according to Claim 2, wherein said composition technique is dissolve composition.
Claim 4
Dependent Claim
25 words
An abstract pattern plate-making system according to Claim 1, wherein said mask has a size larger than a size of each of the divided blocks.
Claim 5
Dependent Claim
44 words
An abstract pattern plate-making system according to Claim 4, wherein said mask has edges which are defined by smooth curved lines and is shaped so that each pair of adjacent masks engage with each other completely in butt-to-the-line form and in a key-and-keyhole relationship.
Claim 6
Dependent Claim
17 words
An abstract pattern plate-making system according to Claim 5, wherein said smooth curved lines are sinusoidal curves.
Claim 7
Dependent Claim
62 words
An abstract pattern plate-making system according to Claim 1, wherein when said mask size is set larger than the block size, said undesired pattern removing means moves pattern data projecting from said endless pattern to an edge at an opposite side of said mask when pattern data in two selected blocks are combined together by a composition technique using said mask data.
Claim 8
Dependent Claim
85 words
A printed matter obtained by using a press plate that is made on the basis of a pattern obtained by dividing first endless pattern data into blocks, combining pattern data in two blocks selected at random from among said divided blocks by a composition technique using mask data having a predetermined pattern, thereby obtaining a pattern of second pattern data, and then repeating said pattern a predetermined number of times both vertically and horizontally as it is or after trimming it to a predetermined size.
Claim 9
Dependent Claim
16 words
A printed matter according to Claim 8, wherein said mask data is multi-valued data having gradation.
Claim 10
Dependent Claim
14 words
A printed matter according to Claim 9, wherein said composition technique is dissolve composition.
Claim 11
Dependent Claim
23 words
A printed matter according to Claim 8, wherein said mask has a size larger than a size of each of the divided blocks.
Claim 12
Dependent Claim
42 words
A printed matter according to Claim 11, wherein said mask has edges which are defined by smooth curved lines and is shaped so that each pair of adjacent masks engage with each other completely in butt-to-the-line form and in a key-and-keyhole relationship.
Claim 13
Dependent Claim
15 words
A printed matter according to Claim 12, wherein said smooth curved lines are sinusoidal curves.
Claim 14
Dependent Claim
104 words
An abstract pattern plate-making system having means for removing an undesired pattern by dividing endless pattern data into blocks and then repeating processing in which pattern data in two blocks selected at random from among said divided blocks are replaced with each other or combined together by using mask data having a predetermined pattern, wherein when the endless pattern is divided into blocks, said undesired pattern removing means allots the blocks so that they are offset from said endless pattern, and moves a region of the mask pattern which projects from said endless pattern to a side opposite to a side where it projects.
Claim 15
Dependent Claim
41 words
An abstract pattern plate-making system according to Claim 14, wherein said projecting region of said mask pattern is moved to a position, which directly faces the position where it projects, at a side opposite to the side where said region projects.
Claim 16
Dependent Claim
49 words
An abstract pattern plate-making system according to Claim 14, wherein said projecting region of said mask pattern is moved to a position, which is offset from the position where it projects by 1/2 pitch of an endless cycle, at a side opposite to the side where said region projects.
Claim 17
Dependent Claim
114 words
A printed matter obtained by using a press plate that is made on the basis of a pattern obtained by repeating an endless pattern a predetermined number of times both vertically and horizontally, said endless pattern being obtained by a process in which endless pattern data is divided into blocks, and pattern data in two blocks selected at random from among said divided blocks are replaced with each other or combined together by using mask data having a predetermined pattern, wherein a region of said mask pattern which projects from said endless pattern is moved to a side opposite to a side where it projects, thereby removing an undesired pattern from said endless pattern.
Claim 18
Dependent Claim
39 words
A printed matter according to Claim 17, wherein said projecting region of said mask pattern is moved to a position, which directly faces the position where it projects, at a side opposite to the side where said region projects.
Claim 19
Dependent Claim
47 words
A printed matter according to Claim 17, wherein said projecting region of said mask pattern is moved to a position, which is offset from the position where it projects by 1/2 pitch of an endless cycle, at a side opposite to the side where said region projects.
Claim 20
Dependent Claim

An abstract pattern plate-making system comprising: first means for preparing mask data on the basis of pattern data at a predetermined position of endless pattern data and for copying pixel data at a predetermined position to another predetermined position on the basis of said mask data; and second means for dividing said endless pattern data into a predetermined number of blocks and for rearranging said divided blocks.
Claim 21
Dependent Claim
110 words
A printed matter obtained by using a press plate made on the basis of a pattern obtained by repeating an endless pattern a predetermined number of times both vertically and horizontally, said endless pattern being obtained by carrying out predetermined image processing with an abstract pattern plate-making system having first means for preparing mask data on the basis of pattern data at a predetermined position of endless pattern data and for copying pixel data at a predetermined position to another predetermined position on the basis of said mask data, and second means for dividing said endless pattern data into a predetermined number of blocks and for rearranging said divided blocks.
