Method and arrangement for generating a dot matrix imprint with control using random output and probability

A method for generating an imprint composed of image points on a substrate using a printing device, comprising the steps of:

• in a control arrangement for a printing device, providing a dot pattern for an imprint comprised of image points represented by said dot pattern;
• with said control arrangement, controlling generation of said imprint on a substrate by said printing device by, for at least one of said image points, identifying a probability with which said one of said image points is generated, generating a random output from a random generator and making an electronic decision, based on said random output and said probability, as to whether said one of said image points is or is not generated on said substrate when printing said imprint, and printing said imprint with said printing device with said one of said image points printed or not printed in said imprint dependent on said electronic decision;
• and
• with said random generator, generating random numbers in a predetermined number range and, in said control arrangement, subdividing said number range into a first sub-range and at least one second sub-range, and generating a random number in said number range for said image point, as said random output;
• and
• in said control arrangement, making said electronic decision by deciding that said image point is generated in said imprint on said substrate when said random number is within said first sub-range, and said image point is not generated in said imprint on said substrate when said random number is within said second sub-range.

• and
• making said electronic decision for said at least one image point using said decision matrix.
