Screen printing device and method for screen printing onto substrates

A printing device for printing onto substrates, comprising:

• a squeegee means;
• at least one printing table;
• wherein the squeegee means is arranged above the at least one printing table;
• the printing table further comprising several conveying means which are arranged side by side and in parallel to one another and each having at least one printing nest such that a substrate can be transported in each case to each printing nest below the squeegee means and out of the printing nest after a printing process has taken place;
• wherein the squeegee means further comprises a single printing screen which extends over all of the printing nests and which has a printing pattern for each printing nest, and wherein the squeegee means has at least one squeegee which can be moved over each printing nest in order to print successively onto the substrates which are arranged in the printing nests;
• the printing device further comprising:
• at least one sensor means for detecting the position and/or alignment of a substrate arranged in a respective printing nest being assigned to each printing nest, and
• at least one controllable adjusting means for aligning and/or positioning the respective substrate and the printing screen to one another being assigned to the printing table and/or the squeegee means,
• wherein a correcting of the alignment and/or position of the respective substrate and of the printing screen to one another takes place in that period of time, in which the squeegee is moved from a substrate, which has been printed onto previously, to a substrate, which is to be printed onto.
