Dynamic pattern transfer printing and pattern transfer sheets with spaced groups of trenches

A dynamic pattern transfer printing system comprising:

• at least one laser scanner configured to illuminate with at least one laser beam a source substrate that comprises a plurality of trenches arranged in a first pattern and holding printing paste, wherein the source substrate is configured to release the printing paste from the trenches and onto a receiving substrate upon the illumination by the laser beam,
• a moveable stage supporting the receiving substrate, wherein the receiving substrate is affixed to the moveable stage during the releasing of the printing paste from the source substrate, and
• a controller configured to control the laser beam illumination along the trenches, and at a scanning direction across the trenches, and further configured to move the moveable stage to yield a second pattern of deposited paste on the receiving substrate, which is different from the first pattern of trenches on the source substrate,
• wherein the first pattern of trenches on the source substrate has a first pitch and the second pattern of deposited paste on the receiving substrate has a second pitch, and
• wherein the controller is further configured to calculate the second pitch with respect to the first pitch, according to a relation between widths of the source substrate and the receiving substrate.

A dynamic pattern transfer printing method comprising:

• illuminating a source substrate with at least one laser beam, wherein:
• the source substrate comprises a plurality of trenches arranged in a first pattern and holding printing paste,
• the source substrate is configured to release the printing paste from the trenches and onto a receiving substrate upon the illumination by the laser beam, and
• the illuminating is carried out along the trenches, and at a scanning direction across the trenches;
• and
• controllably moving the receiving substrate to yield a second pattern of deposited paste on the receiving substrate, which is different from the first pattern of trenches on the source substrate,
• wherein the first pattern of trenches on the source substrate has a first pitch and the second pattern of deposited paste on the receiving substrate has a second pitch, and wherein the dynamic pattern transfer printing method further comprises at least one of:
• moving the moveable stage in the scanning direction to yield the second pattern on the receiving substrate, and configuring the first pitch (p1), the second pitch (p2), a forward speed of the moveable stage (vF) and a scanner speed across the trenches (vS) to have the relation p2=p1·(vS−vF)/vS to make the second pitch smaller than the first pitch (p2<p1);
• and/or
• moving the moveable stage against the scanning direction to yield the second pattern on the receiving substrate, and configuring the first pitch (p1), the second pitch (p2), a backward speed of the moveable stage (vB) and a scanner speed across the trenches (vS) to have the relation p2=p1·(vS+vB)/vS to make the second pitch larger than the first pitch (p2>p1).
