Abstract
Abstract Described is a method for pattern repeat presetting of a multi color screen printing machine wherein the screen printing stencils to be used are pre-set on the basis of independently determined stencil-data and printing position data by establishing a fixed predetermined relation between these data. Also described is a multi color screen printing device having means for setting the lengthwise, widthwise and diagonal pattern repeat with use of a computer and independently determined printing position and stencil data. The invention also relates to a device of determining stencil data.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
112 words
A method for the pattern repeat presetting of a multi-printing position rotary screen printing machine for multi-colour printing, comprising the steps of: (a) providing patterned cylindrical stencils, each of said stencils comprising one or more stencil reference points related to the pattern; (b) providing an end ring at each end of each of said stencils, at least one of said end rings comprising an end ring reference point; (c) placing said stencils in the printing positions of the rotary screen printing machine; and (d) independently determining stencil data and printing position data, such that for each printing position a fixed relation between the stencil data and the printing position data is set.
Claim 2
Independent Claim
112 words
A method for the pattern repeat presetting of a multi-printing position rotary screen printing machine for multi-colour printing, comprising the steps of: (a) providing patterned cylindrical stencils, each of said stencils comprising one or more stencil reference points related to the pattern; (b) providing an end ring at each end of each of said stencils, at least one of said end rings comprising an end ring reference point; (c) placing said stencils in the printing positions of the rotary screen printing machine; and (d) independently determining stencil data and printing position data, such that for each printing position a fixed relation between the stencil data and the printing position data is set.
Claim 3
Dependent Claim
29 words
A method according to claim 1, in which the stencil data are determined by measuring the relative positions between the end ring reference point and the stencil reference points.
Claim 4
Dependent Claim
80 words
A method according to claim 1, in which the printing position data of a nonreference printing position relative to a reference printing position are obtained by: (a) providing test stencils with associated end rings having known stencil data and reference points; (b) placing said test stencils in said reference printing position and in said nonreference printing position; (c) printing said reference points of said test stencils; and (d) measuring the deviance between said printed reference points of said test stencils.
Claim 5
Dependent Claim
80 words
A method according to claim 2, in which the printing position data of a nonreference printing position relative to a reference printing position are obtained by: (a) providing test stencils with associated end rings having known stencil data and reference points; (b) placing said test stencils in the reference printing position and in the nonreference printing position; (c) printing said reference points of said test stencils; and (d) measuring the deviance between said printed reference points of said test stencils.
Claim 6
Independent Claim
95 words
A device for multi-colour rotary screen printing, comprising; (a) several means for accommodating patterned cylindrical stencils, each of said stencils comprising one or more stencil reference points related to the pattern and two end rings, at least one of said end rings comprising an end ring reference point; (b) means for setting the widthwise pattern repeat, lengthwise pattern repeat and the diagonal pattern repeat; and a computer having a memory file in which predetermined printing position and stencil data are accommodated, said computer generating the printing position setting data for the given stencil/printing position combination.
Claim 7
Independent Claim
95 words
A device for multi-colour rotary screen printing, comprising; (a) several means for accommodating patterned cylindrical stencils, each of said stencils comprising one or more stencil reference points related to the pattern and two end rings, at least one of said end rings comprising an end ring reference point; (b) means for setting the widthwise pattern repeat, lengthwise pattern repeat and the diagonal pattern repeat; and a computer having a memory file in which predetermined printing position and stencil data are accommodated, said computer generating the printing position setting data for the given stencil/printing position combination.
