Claim 4

The method according to claim 1, wherein the adjustment values for the three adjusting devices are fed directly to drive motors acting on the adjusting devices in the printing machine.

Claim 5

The method according to claim 1, wherein the displacement values are used for changing the position of the print in relation to the material.

Claim 6

The method according to claim 1, wherein the displacement values are used for changing the position of the material intended for printing in relation to the print.

Claim 7

The method according to claim 5, wherein the displacement values are used for displacing the material along the printing table by displacing the second registering means.

Claim 8

The method according to claim 5, wherein the displacement values are used for displacing the printing table, together with a fixed material, in relation to the print.

Claim 9

The method according to claim 1, wherein two adjustable scanners are used for scanning the marks.

Claim 10

An arrangement for adjusting a print made in a printing machine on a material for substantial correspondence in relation to a reference pattern, comprising: (a) a reference pattern serving as an original applied to a registering table separate from the printing table and provided with first registering means for registering the reference pattern, the first registering means corresponding to second registering means on the printing machine, (b) scanning means for scanning the reference pattern formed on the original to locate predetermined marks, (c) means for recording position values for the marks obtained from the scanning means, (d) a material supplied with the print by the printing machine while the material is registered in the second registering means of the printing machine, said material being thereafter applied to the first registering means of the registering table, (e) said material, which is printed according to "d", is scanned by the scanning means to locate marks on the print corresponding to the predetermined marks on the reference pattern, (f) means for recording position values for the marks on the print obtained from the scanning means, (g) means for comparing the position values recorded in "c" and "f", (h) means for determining any deviation between the marks on the reference pattern and the print with respect to a numerical value and direction, (i) means for determining displacement values from the determined deviation which values are appropriate for compensating for the deviation to apply a subsequent print substantially exactly to a further material in relation to the reference pattern, and (j) a computer for evaluating the displacement values and for deriving adjustment values which are supplied to adjustment means to compensate for the deviation to ensure that the subsequent print is applied substantially exactly to the further material.

Claim 11

An arrangement for adjusting a print made in a printing machine on a material for substantial correspondence in relation to a reference pattern, comprising: (a) a reference pattern serving as an original applied to a registering table separate from the printing table and provided with first registering means for registering the reference pattern, the first registering means corresponding to second registering means on the printing machine, (b) scanning means for scanning the reference pattern formed on the original to locate predetermined marks, (c) means for recording position values for the marks obtained from the scanning means, (d) a material supplied with the print by the printing machine while the material is registered in the second registering means of the printing machine, said material being thereafter applied to the first registering means of the registering table, (e) said material, which is printed according to "d", is scanned by the scanning means to locate marks on the print corresponding to the predetermined marks on the reference pattern, (f) means for recording position values for the marks on the print obtained from the scanning means, (g) means for comparing the position values recorded in "c" and "f", (h) means for determining any deviation between the marks on the reference pattern and the print with respect to a numerical value and direction, (i) means for determining displacement values from the determined deviation which values are appropriate for compensating for the deviation to apply a subsequent print substantially exactly to a further material in relation to the reference pattern, and (j) a computer for evaluating the displacement values and for deriving adjustment values which are supplied to adjustment means to compensate for the deviation to ensure that the subsequent print is applied substantially exactly to the further material.

Claim 12

The arrangement according to claim 9, wherein the computer evaluates the adjustment values in digital form for three adjusting means.

Claim 13

The arrangement according to claim 9, wherein the computer includes means for evaluating the adjustment values and acting on servo motors coupled to the adjustment means.

Claim 14

The arrangement according to claim 9, wherein the scanning means includes a plurality of phototransistors and one light-emitting diode.

Claim 15

The arrangement according to claim 12, wherein the scanning means includes at least four phototransistors and one light-emitting diode, each of the phototransistors being directed toward a reflecting mark on the original or the print.

Claim 16

The arrangement according to claim 9, used for adjusting the position of a stencil in relation to the printing table of a stencil printing machine and a material placed on the printing table, the material being intended to receive a print corresponding to the stencil pattern wherein the stencil is fixed in a frame which is adjustable in an outer frame, the print corresponding to the stencil pattern is applied to the material which is fixed to the second registering means on the printing table of the stencil printing machine, and wherein the adjustment means adjusts the position of the stencil in relation to the printing table.

Claim 17

The arrangement according to claim 9, wherein the adjustment means changes the position of the print in relation to the material.

Claim 18

The method according to claim 9, wherein the adjustment means changes the position of the material intended for printing in relation to the print.

Claim 19

The arrangement according to claim 16, wherein the adjustment means displaces the material along the printing table by displacing the second registering means.

Claim 20

The arrangement according to claim 16, wherein the adjustment means displaces the printing table, together with a fixed material, in relation to the print.

Claim 21

The arrangement according to claim 9, wherein the evaluation of the adjustment values are related to the first registering means rather than to the marks.

Claim 22

The arrangement according to claim 9, wherein the scanning means comprises two scanners which are adjustable in relation to the marks.
